Back in 2015, I interviewed the Chief Technology Officer Dr. Christopher Case of Oxford PV during the InterSolar North America in San Francisco, CA. Dr. Case introduced me to a potentially game-changing solar technology, the perovskite solar cell technology, that holds much promise for lowering the cost and boosting the performance of solar power by increasing photovoltaic efficiency of any solar photovoltaic thin film material to 30+% in a perovskite tandem layer (which is more than the maximum efficiency achieved in traditional mono-and poly-crystalline silicon cells). In laboratories, perovskite cells are manufactured by spin-coating, spraying, or “painting” them onto a substrate (material that provides the surface for the chemicals to crystalize on). Perovskites are only about half a micron thick while silicon layer is roughly 200 microns. The main hurdle for perovskite is durability. Perovskites are very sensitive to oxygen, moisture, and heat, therefore, requiring heavy encapsulation to protect the cell, leading to increased cost and weight of solar cell. Oxford PV’s tandem cell conversion efficiency is 29.52%. More research and development and data are needed for testing its efficiency, stability, as well as increasing lifespan and replacing toxic materials with safer ones. Company such as Saule Technologies has some very interesting perovskite products in the works: 1. they have a perovskite photovoltaic glass ( a semi-transparent perovskite solar cell printed onto flexible foils and overlayed with layers of glass), making it a window that generates electricity. 2. Saule is also producing energy-harvesting sun-blinds that can block intense summer sunlight, and allowing sunlight to enter the building in mornings and evenings to provide natural light and passive heating. These blinds can be adjusted manually or automatically. 3. In May of 2021, Saule launched the world’s first industrial production line of perovskite solar panels in Poland. Jinko Solaris also working on rolling out perovskite technology. The perovskite solar cell could be the future of energy, in the video published on Sep. 14, 2021, “Perovskite Solar Cells Could Be the Future of Energy“, below:
Perovskite mineral was discovered over 150 years ago, but it’s only recently that scientists have been able to synthesize the properties of the material in laboratories using commonly available chemicals. And what they’re finding is that it can give a big boost to the performance of existing solar cell technology. This week we take at look at how it works, in the video published on Aug. 9, 2020, “Perovskite Solar Cells: Game changer?“, below:
In the video published on March 26, 2021, “Perovskite solar out-benches rivals-2021| perovskite solar cells shines a little brighter“, below:
Perovskite, a calcium titanium oxide mineral discovered in the Ural Mountains of Russia in 1839. This new old material is generating quite an explosive buzz because scientists have found, in recent years, that it is a great material to be used in solar absorption applications. It can be made simply and inexpensively by using common wet chemistry lab methods and low cost equipment instead of the expensive deposition equipment common in the semiconductor industry. To take a look at how this process is made cheap and accessible, I’m sharing the video below:
These solar (photovoltaic) cells are made in tandem (layer by layer) fashion on a specially coated glass support. In the video above:
the glass is coated with a dense layer of titanium dioxide, by robotic arm, to prevent electrical charge generated by sunlight from leaking out of the cell.
a less dense porous oxide layer covers the dense oxide layer (usually titanium dioxide, other oxides may also be used).
a simple high speed spin coater deposits this layer from solution and spreads this coating evenly across the device.
heating this glass/device in an oven conditions it for solar cell use.
prepare the Perovskite material (which absorbs in the broad range of solar spectrum) by combining 2 precursor materials: PbI2 (lead iodide) & CH6IN (methylammonium iodide)
drip the liquid phase mixture (from 5.) onto the oxide coated device (from 4.)
spin the resulting device in 6 to assure even coating
applying halide solution
heating the device resulting from 8 on a hot plate–>spontaneously crystallizes precursors in freshly deposited liquid
color changes also result from crystallization process resulting from 9.
Such tandem product has the advantage of being able to be introduced into existing infrastructure of current silicon module manufacturing process, boosting its efficiency. With added few steps toward the end of the production line, the coating (equivalent to second solar cell) takes advantage of the blue portion of the solar spectrum and may improve the solar cell efficiency by 20-25% above the underlying silicon. The fact that Perovskite-based solar cell technology is of earth abundant material also insures its availability and low cost. Its high absorption in solar spectrum enables it to have comparable characteristics to that of gallium arsenide. Its ability to change its sensitivity to different band gaps in solar spectrum allows it to make different architectures in tandem solar cells. It can truly be considered as the Custom Solar Absorber! In short term, Perovskite-based solar cell may boost the efficiency level of existing technology and in the long term. It may be a stand-alone technology with closer efficiency level to that of gallium arsenide but at a much lower cost. It may potentially be sprayed, ink-jet printed, dip-coated, etc. It is no wonder that Dr. Case commented, “the perovskite in solar application is the fastest increasing photovoltaic efficiency of any solar photovoltaic thin film material ever! In just a few years, it went from a lab efficiency of about 6% to well over 17%…the material is a very good solar absorber….bringing the material to 25% efficiency in a monolithic layer and 30%+ in a perovskite tandem layer….potentially the future replacement for silicon.” The perovskite thin-film solar cells, is currently being developed by Oxford PV (a spin-out from the University of Oxford in 2009-2010 to commercialize this technology, which has exclusively licensed the intellectual property developed by Professor Henry Snaith and his team of 20 scientists). Below, Professor Henry Snaith will embellish upon the development of this solar technology, in the video published on Jan. 10, 2014, “Perovskites: The Emergence of a New Era for Low-Cost, High-Efficiency Solar Cells“, below :
Henry J. Snaith is Professor of Physics in the Clarendon Laboratory at the University of Oxford and Fellow of the Royal Society. He has pioneered the field of perovskite solar cells and published hundreds of papers. He is founder and CSO of Oxford PV, which holds the largest perovskite patent portfolio worldwide and focuses on developing and commercializing perovskite PV technology. In this interview, he discusses the present status and future prospects of perovskite PV, in the video published on Nov. 11, 2018, “The Path to Perovskite on Silicon PV | Prof. Henry Snaith“, below:
Oxford PVplans on continuing to optimize this technology’s cell efficiency and accelerate the transfer of the technology into production. Furthermore, it aims to develop the range of substrates to which the cells can be applied. With its promising future, we, the solar enthusiasts and investors alike, should keep our eyes on Oxford PV in the coming years. In the next few years, we anticipate that Dr. Henry Snaith and his team of scientists will continue to tackle challenges in trap densities, doping densities, mobility, mechanisms for free carrier generations, etc., to further improve device performance. You will find that many in the solar industry share the optimism of Professor Henry Snaith and Dr. Christopher Case.

2. In the video published on Nov. 17, 2017, “Everything you ever wanted to know about perovskite“, below:
Keep in mind that Shockley-Queisser limit applies to silicon solar cell and not to perovskite solar cell. The Shockley-Queisser limit is calculated by examining the amount of electrical energy that is extracted per photon of incoming sunlight.For better understanding of Shockley-Queisser limit, please refer to the excerpt from wikipedia, in italics, below:In a traditional solid-statesemiconductorsuch as silicon, a solar cell is made from two doped crystals, one an n-type semiconductor, which has extra free electrons, and the other a p-type semiconductor, which is lacking free electrons, referred to as “holes.” When initially placed in contact with each other, some of the electrons in the n-type portion will flow into the p-type to “fill in” the missing electrons. Eventually enough will flow across the boundary to equalize the Fermi levels of the two materials. The result is a region at the interface, thep-n junction, where charge carriers are depleted on each side of the interface. In silicon, this transfer of electrons produces a potential barrier of about 0.6 V to 0.7 V.[6]When the material is placed in the sun, photons from the sunlight can be absorbed in the p-type side of the semiconductor, causing electrons in the valence band to be promoted in energy to the conduction band. This process is known asphotoexcitation. As the name implies, electrons in the conduction band are free to move about the semiconductor. When a load is placed across the cell as a whole, these electrons will flow from the p-type side into the n-type side, lose energy while moving through the external circuit, and then go back into the p-type material where they can re-combine with the valence-band holes they left behind. In this way, sunlight creates an electric current.[6]In physics, the Shockley–Queisser limit (also known as the detailed balance limit, Shockley Queisser Efficiency Limit or SQ Limit, or in physical terms the radiative efficiency limit) is the maximum theoretical efficiency of a solar cell using a single p-n junction to collect power from the cell where the only loss mechanism is radiative recombination in the solar cell. It was first calculated by William Shockley and Hans-Joachim Queisser at Shockley Semiconductor in 1961, giving a maximum efficiency of 30% at 1.1 eV.[1] This first calculation used the 6000K black-body spectrum as an approximation to the solar spectrum. Subsequent calculations have used measured global solar spectra (AM1.5G) and included a back surface mirror which increases the maximum efficiency to 33.7% for a solar cell with a bandgap of 1.34 eV.[2] The limit is one of the most fundamental to solar energy production with photovoltaic cells, and is considered to be one of the most important contributions in the field.[3]The limit is that the maximumsolar conversion efficiency is around 33.7% for a single p-n junction photovoltaic cell, assuming typical sunlight conditions (unconcentrated, AM 1.5 solar spectrum), and subject to other caveats and assumptions discussed below. This maximum occurs at a band gap of 1.34 eV.[2] That is, of all the power contained in sunlight (about 1000 W/m2) falling on an ideal solar cell, only 33.7% of that could ever be turned into electricity (337 W/m2). The most popular solar cell material, silicon, has a less favorable band gap of 1.1 eV, resulting in a maximum efficiency of about 32%. Modern commercial mono-crystalline solar cells produce about 24% conversion efficiency, the losses due largely to practical concerns like reflection off the front of the cell and light blockage from the thin wires on the cell surface.The Shockley–Queisser limit only applies to conventional solar cells with a single p-n junction; solar cells with multiple layers can (and do) outperform this limit, and so can solar thermal and certain other solar energy systems. In the extreme limit, for a multi-junction solar cell with an infinite number of layers, the corresponding limit is 68.7% for normal sunlight,[4]or 86.8% using concentrated sunlight.[5] (See Solar cell efficiency.)

On Monday, September 20, 2021, the share of renewable energy (solar, wind, and hydro) on Australia’s main electricity grid shot above 60% (at 60.1%) for the first time at 12:10 pm, exactly one day and 15 minutes after its previous peak and record of 59.8% on Sunday, September 19, 2021, according to Dylan McConnell of the Climate Energy College in Melbourne, Australia, using data from OpenNEM. This new peak highlights the increased pace of transition into the clean or renewable energy and the shrinking output of coal as more solar and wind are rolled out across Australia. According to another data watcher, Geoff Eldridge from NEWLog, Sunday, September 19, 2021, did not just break the record for the share of renewable energy, but also the record for instantaneous wind and solar at 57%. The Australian Energy Market Operator also noticed: NSW record maximum rooftop solar PV (2,694.4 MW) and corresponding lowest minimums for network demand (4,867.4 MW) and Operation Demand (5,065.0 MW) and tweeted on Friday, September 24, 2021, “Spring is the season for records to bloom! Forecast mild temperatures and sunny weather in NSW and QLD on Sunday may see rooftop solar drive down energy demand from the grid to a new record low!” With such occurrence, NSW, the Australian state grid with the highest dependency on coal generation, would find it easier to align with the state government’s push to replace the aging coal fleet of more than 10GW with wind, solar, and storage under its renewable infrastructure plan. According to Eldridge of NEMLog, coal output on the main grid was at a record minimum of 9,161.6 MW at noon on Sunday, September 19, 2021 (or, at leas the lowest since Nov. 1, 2020), and was down 153.57 MW on the previous minimum on Sunday, Aug. 22, 2021. It was also a record low share of coal generation (38.97%) on the main grid and for combined coal and gas (40.05%). The share of solar and wind could have been significantly higher were it not for the level of curtailment, either economic (switching off to avoid negative prices) or network (being forced to switch off due to grid issues or capacity constraints). On Sunday, September 19, 2021, the level of curtailment was more than 3.5 GW when that short-lived record was set. As the rollout of solar, wind, and storage (both battery and pumped hydro) continues to enter the grid, more records will change. AEMO forecasts that the rooftop solar, alone, will be able to reach 100% of demand in the state of South Australia some time this Spring (of Australia), around October, a FIRST for any gigawatt scale grid in the world! AEMO is also predicting that rooftop solar could meet up to 75% of demand on the entire main grid within next five years and is preparing the national grid to accommodate times of up to 100% solar and wind by 2025. ABC News: South Australia’s renewable energy boom has achieved a global milestone, in the video published on Oct. 25, 2020, “ABC News: South Australia runs purely on solar power in world first“, below:
Australia is preparing to build the world’s most powerful solar power plant. Engineers and builders will have to solve complex problems to cover an area equal to 17 thousand football fields that accommodate photovoltaic panels with a total capacity of 10 Gigawatts. The second challenge will be to transfer this energy to Singapore, the main consumer of electricity. There is also talk of exporting energy to Indonesia and various parts of Asia. But how exactly will the power plant be able to power a country more than three thousand kilometers away? In the video published on Sep. 21, 2021, “How Australia’s Most Powerful $16 Billion Solar Power plant Will Power Singapore“, below:
To begin with, it is worth understanding why energy problems have arisen in one of the most developed countries in the world. Australia faces regular power outages, and, unfortunately, South Australia suffers the most. There may be a lot of reasons: for instance, in September 2016, due to a storm, almost the entire state was left without electricity. One reason for the outages is that there are not enough storage facilities on the territory to supply more electricity during peak loads. The local authorities could not ensure the commensurate development of their own energy or storage capacities capable of providing electricity supplies during calm or cloudy weather. And it is quite difficult to restore the network because of the climatic conditions and long distances – Australia is not a tiny country. At the same time, electricity prices in the country are considered one of the highest in the world, in the video published on Jan. 13, 2021, “HOW ELON MUSK MANAGED TO SOLVE THE ENERGY CRISIS IN AUSTRALIA“, below:

Elon Musk talks about his plan for the sun. It’s already very normal day when Elon Musk talks about some revolutionary idea and this speech is no exception, in the video published on Sep. 12, 2021, “Elon Musk – Sun is The Future“, below:
In order to be sustainable, we have to have sustainable means of production and consumption of energy, to drive electric cars in order to reduce CO2 emission, and to generate sustainable energy. Sustainable energy may be in the form of solar, nuclear, hydro-thermal, hydro, and wind energy. The primary form of energy to be generated will be solar. Sustainable or solar energy production combined with stationary storage, the world can be powered many times over by solar energy. About a third of our energy use is electricity, about a third of energy use is for for heating, and a third of energy use is in transport. There is enough energy from the sun to support all three areas of energy use/need. There is 1 gw per square km amount of energy coming from the sun. The earth is already almost entirely solar powered. The amount of energy needed to power our civilization is tiny compared to energy from the sun (1 gigabit per square kilometer). At 20% efficient solar panels, that’s 200 Mw per square kilometer. There would be plenty of energy for all three areas of energy use from solar, with some contribution from wind, geothermal, and tidal. And we need to stop subsidizing burning fossil fuels.

Terrific, on Thursday, Sep. 9, 2021, Australia has once again beaten its previous record for the share of renewables on its main grid, reaching instantaneous 58.3% , and also setting a new record for the share of wind and solar in the grid. According to OpenNEM’s data, the new record was set at 12:30 pm, and easily beat the previous record of 57.3% set just a few days earlier. Since such records are usually set on weekends when industrial use is lower, it is quite telling when this new record was set on a weekday.
Wind and solar reached 56.1% at 12:30 pm, also a record of total output, although the aggregate total of about 14.5 GW was not a record. At the time of the record, rooftop solar alone contributed 32.4% of the total demand of about 24 GW while wind farms contributed 12.9%, and utility scale solar farms 10.8%. Coal was reduced to 40% of the output, with black coal in Queensland and NSW providing 29.4% and brown coal in Victoria 10.4%.
After the infamous meltdown in 1986 resulted from a flawed reactor design and poor training, other nuclear reactors at the Chernobyl facility continued to operate until the turn of the century. For the past 18 years, Chernobyl has been nothing but an abandoned wasteland due to the high level of radiation, making the Chernobyl exclusion zone unsuitable for agriculture or forestry. This exclusion zone is a 1000 square mile area around the Chernobyl nuclear plant mostly uninhabited and unused since the 1986 disaster. Since there is already substantial electrical infrastructure in place left over from the nuclear plant and the fact that the land is unused and cheap, the site is an excellent choice for large solar farm(s) to be installed.
“It’s not just another solar power plant…it’s really hard to underestimate the symbolism of this particular project. ” the chief executive of Solar Chernobyl LLC, Evhen Variagin, told reporters at the unveiling of a 1 MW joint project that can power 2,000 homes, on Friday, October 5, 2018, by Ukrainian company Rodina and German company Enerparc AG, costing about $1.2 million (1 million euros) and benefiting from feed-in-tariffs that guarantee a certain price for power. The head of the Chernobyl nuclear plant Valery Seyda said, “It is the first time the site has produced power since 2000, when the nuclear plant was finally shut down. But now we are seeing a new sprout, still small, weak, producing power on this site and this is very joyful.”
Between January and September of this year (2018), more than 500 MW of renewable power capacity is added to Ukraine, more than twice as much as in 2017, according to the Ukrainian government.The head of the Office of the National Investment Council of Ukraine, Yulia Kovaliv, said investors want to reap the benefits from a generous subsidy scheme before parliament is due to vote on scrapping it in July next year. “Investors expect that in the renewable energy sector facilities launched before 2019 will operate on the current beneficial system of green tariffs…that is why investors want to buy ready-to-build projects in order to complete construction before that time.” Yulia Kovaliv told Reuters reporter on the sidelines of a conference in Odessa in September.
Cheap land and sunny skies are attracting interests from around the world. Two Chinese companies, GCL System Integration Technology Co. Ltd. and China National Complete Engineering Corp, are also building a one-gigawatt solar power plant (enough to power 100 million LED bulbs) to the South of Chernobyl. Another dozen smaller investors are also installing solar parks nearby on a smaller scale. These entrepreneurs are not deterred by the challenges of major construction projects in nuclear contamination zone. Engineering work has already begun, but there has not been any public disclosure about safety measures, the completion date, nor a price for the project.

Hurricane Florence was a Category 4 at its peak, at 130 miles per hour (or 210 kilometers per hour) wind two days before making its landfall on September 14, 2018. That was so close to the threshold (140-160 miles per hour) of the design of new solar farms. About a third of the 3,000 megawatts of solar capacity connected to Duke Energy Corp’s system went down initially, according to utility spokesman Randy Wheeless. As of this week, about nine projects in North Carolina remained offline. Four of these were due to damage to Duke Energy facilities and five were due to damage to the project themselves. Wheeless said facilities that suffered the most tended to be five megawatt projects connected to Due’s distribution system.
Duke had been trying to get developers to move toward larger solar projects to connect largely to its transmission system, the high-voltage wires that link Duke plants to the distribution system that delivered power to homes and businesses. With hundreds of solar projects connected to Duke’s grid in North Carolina, the number of damaged projects remained small. Senior vice president at Strata Solar, Brian O’Hara, said that the Chapel-Hill based solar developer with more than 140 projects in the state saw damage at only two facilities. O’Hara said, “Duke has done a commendable job responding quickly and getting our facilities back online shortly after we notified them that they were inspected and ready to reconnect….our teams have coordinated closely with Duke’s recovery team, and it has been professional, responsive and pretty seamless.” The chief operating officer for Durham-based Ecoplexus Inc., John Morrison, said his company also saw very little damage, with only two of the 16 sites operating in North Carolina suffering some broken modules, amounting to less than 0.34% of the the developer’s modules, “not enough to even exceed the insurance deductible.” Spokesman for the California-based Cypress Creek Renewables, Jeff McKay, also reporting no notable damage in its solar fleet. As for Duke itself, its only project that suffered damage was the 60-megawatt Monroe Solar project in Union County, with few panels being damaged by wind. Duke’s Fayetteville, Warswa and Camp Lejeuene solar projects were all undamaged and returned to service as soon as grid operations allowed. Most outages during and after the worst of the hurricane Florence were due to problems with Duke’s grid rather than problems at the projects themselves.

Yes, this is the year to celebrate the Bridgestone World Solar Challenge’s 30th Anniversary in Australia! The event began on Sunday, Oct. 8, 2017, at State Square, in front of the Parliament House of Northern Territory (at 6:00 am-8:30 am, with the first car leaving at 8:30 am) and expect to see the solar car teams arriving at Victoria Square/Tarntanyangga of Adelaide, Australia (between Wednesday, Oct. 11 to Sunday, Oct. 15, 2017). After teams of students from 30 countries designed and built their own solar cars, they have traversed 3,000 km between Darwin and Adelaide in 5-8 days, to meet the challenge of 3 classes of World Solar Challenge of 2017: Challenger Class; Cruiser Class; and Adventure Class.
World Solar Challenge was the brain child of solar pioneer Hans Tholstrup and car racer Larry Perkins. In 1982, they embarked on a quest to drive a home-built solar car The Quiet Achiever across Australia from West to East. Hans also enthusiastically urged others to explore and develop solar transport. So, the World Solar Challenge was born. Inaugurated in 1987 with pioneer sponsor, the South Australian Tourism Commission, the World Solar Challenge continues to showcase the development of advanced automotive technology and promote alternatives to conventional vehicle engines.
Using no more than six square meters of solar panels, bright young minds from different parts of the world are on track in developing efficient solar powered electric vehicles. Every two years, teams from international universities and technical institutes gather with private entrepreneurs at Down Under to promote the knowledge and fact that sun/solar is the future.
Above are photos and videos from World Solar Challenge 2015. Keep in mind that these solar car teams will be arriving tomorrow Thursday, Oct. 12, 2017, at Victoria Square/Tarntanyangga, Adelaide, Australia. If you will be near Adelaide, check out Victoria Square for views of many interesting designs of solar cars.

Within two weeks after Hurricane Irma swept over St. John (smallest of the three main U.S. Virgin Islands), a survivor used debris from a nearby home to spell out “SEND TESLA“. With significant loss of life, lack of drinking water, dehydration, food scarcity, and disappearing power grid in Puerto Rico, the humanitarian effort by Tesla stepping in to help was truly welcomed. Bloomberg reported that Tesla had been sending hundreds of its Powerwall battery systems to be paired with solar panels to help restore the power back to the battered island. The monumental destruction brought by hurricanes Irma and Maria on the U.S. Virgin Islands and Puerto Rico in September is opening up the possibilities for companies such as Tesla to move in and establish a presence. Tesla sent representatives to the island to begin signing up survivors for solar services.
Tesla indicated that some of the systems (Tesla Powerwall+Solar Panels) are already in Puerto Rico and others are on their way. Bloomberg also reported, “The company (Tesla) has employees on the ground to install them and is working with local organizations to identify locations.” The Puerto Rico island is still mostly without without power.
Thanks to Tesla for bringing power/electricity back to some of the people of Puerto Rico and U.S. Virgin Islands.
Mia Farrow’s Twitter further reminds us of the BBC report of 55% of the people in Puerto Rico are without drinking water. Hopefully, President Trump’s visit tomorrow (Tuesday, Oct. 3, 2017) to Puerto Rico will bring more attention, help, and water being dropped in by the U.S. National Guard to these Americans at Puerto Rico.

Hyperloop pod carriages major components designed by Elon Musk (presented at WindermereSun.com & sunisthefuture.net)
Hyperloop tube (presented at WindermerSun.com & sunisthefuture.net)
(Please click on red links & note magenta)
The vision of Elon Musk, once a simple sketch in Musk’s blog back in August of 2013, will soon become a reality. At the speed of 760 mph, this high speed mode of transport would allow commuters to travel between Orlando and Miami in 26 minutes or between Los Angeles and San Francisco in 30.15 minutes (twice as fast as commercial air travel). It is truly enabling us to travel at a blink of an eye. As an alternative to boats, aircrafts, automobiles, and trains, Elon Musk’s vision was that of hyperloop transporting people (and cars) via electromagnetically levitated pods/capsules enclosed inside of steel low-pressure tubes. Musk described the design looking like a shotgun with the tube running side by side for most of the journey and closing the loop at either end. The tube is partially evacuated to reduce friction. The capsule or pod carriage rides on a cushion of air forced through multiple openings at the capsule’s bottom (as though capsules are suspended midair by air casters, think of pucks on air hockey table float around ), further reducing friction. The capsules would be propelled (accelerate or decelerate) by linear induction motors (which are magnetic) placed at intervals along the route. These tubes would be mounted on columns 50 to 100 yards apart and the pods or capsules inside would travel up to 760 mph. Finally the hyperloop vehicle itself contains air compressor near the front to intake excess air in the tube and exhaust in the back because excess air would cause resistance and drag that would slow down the vehicle.
Since Elon Musk has made the hyperloop design/technology open source, there had been multiple governments, universities, companies worldwide exploring this concept . Hyperloop One, launched in 2014, previously known as Hyperloop Technologies, is a company in Los Angeles, California, that is working to commercialize the Hyperloop for moving passengers and/or cargo at airline speeds at a fraction of the cost of air travel. The concept of Hyperloop transportation was introduced and named by Elon Musk in August 2013, although he is not directly involved with Hyperloop One. The company has raised $160 million and demonstrated a form of propulsion technology in May 2016 at its test site north of Las Vegas. Its new round of funding on September 21, revealing an additional $85 million received from investors such as DP World, Caspian VC Partners, WTI, and OurCrowd.com. So, in total, Hyperloop One has raised $245 million since its launch in 2014 and is now worth more than $700 million. Hyperloop One has completed a 500m Development Loop (DevLoop) in North Las Vegas and just after midnight on May 12, 2017, the company held its first full-scale Hyperloop test, becoming the first company in the world to test a full-scale Hyperloop. The test combined Hyperloop components including vacuum, propulsion, levitation, sled, control systems, tube, and structures.
Hyperloop One is currently developing passenger and cargo system routes in the United States, Canada, Finland, Sweden, the Netherlands, and the United Arab Emirates. It is also in early talks with Indian government to build one in India. Its publicly stated goal is to deliver a fully operational Hyperloop system by 2021. Officials with Hyperloop One placed the Florida route on a list of 10 that had cleared an initial proposal review. Each of the cities will now receive resources to help develop feasibility studies for the regions.
“The Hyperloop One Global Challenge started as a call to action for innovators, engineers, trailblazers and dreamers around the world who shared our vision of creating a new mode of transportation,” stated Shervin Pishevar, cofounder and executive chairman of the Hyperloop One group, in an announcement of all of the finalists. Below, is the announcement of Hyperloop One Global Challenge in June of 2016:
Outcome of The Hyperloop One Global Challenge, announced on September 14, 2017:
