Solar Powered Maglev/Evacuated Tube Transport For Our Magical Planet Earth

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links & note magenta)

Wow, we are surely living in a magical time! Another form of upcoming mass transport is based on the magical Maglev (derived from magnetic levitation) with upgrade.   It is a transport method that uses magnetic levitation to move vehicles without touching the ground. A vehicle would travel along a guideway using magnets to create both lift and propulsion, thereby reducing friction and allowing higher speed. Here is a TED Talk that demonstrates this concept, below:


Of  course, such a magical technology would have many potential applications;for example: the Shanghai Maglev Train, also known as the Transrapid, is the fastest commercial train currently in operation and has a top speed of 430 km/h (270 mph) (and once reached 311 mph or 501 km/h in a pre-launch test). The line was designed to connect Shanghai Pudong International Airport and the outskirts of central Pudong, Shanghai. It covers a distance of 30.5 kilometres in 8 minutes.

Maglev trains move more smoothly and more quietly than wheeled mass transit systems. They are relatively unaffected by weather. The power needed for levitation is typically not a large percentage of its overall energy consumption; most goes to overcome drag, as with other high-speed transport. Maglev trains hold the speed record for rail transport. Vacuum tube train systems might allow maglev trains to attain still higher speeds, though no such vacuum tubes have been built commercially yet.

Compared to conventional (normal) trains, differences in construction affect the economics of maglev trains, making them much more efficient. For high-speed trains with wheels, wear and tear from friction along with the “hammer effect” from wheels on rails accelerates equipment wear and prevents high speeds. Conversely, maglev systems have been much more expensive to construct, offsetting lower maintenance costs. Despite decades of research and development, only two commercial maglev transport systems are in operation, with two others under construction. In April 2004, Shanghai’s Transrapid system began commercial operations. In March 2005, Japan began operation of its relatively low-speed HSST “Linimo” line in time for the 2005 World Expo.

In its first three months, the Linimo line carried over 10 million passengers. South Korea and the People’s Republic of China are both building low-speed maglev routes of their own designs, one in Beijing and the other at Seoul’s Incheon Airport. Many maglev projects are controversial, and the technological potential, adoption prospects and economics of maglev systems are often debated.

Even though no commercial vacuum tube train systems have been built yet, scientists at Southwest Jiaotong University in China have reportedly built a maglev train that could reach 1,800 mph (2,900 km/h). A vacuum is used to minimize air resistance, according to The Daily Mail.Dr. Deng Zigang, the project leader, claims such vacuum tube train systems could be used for military or space launch systems. At the high speed of maglev train system, air resistance becomes a serious issue.  Dr. Deng Zigang writes in his paper, “If the running speed exceeds 400 km (250 miles) per hour, more than 83% of traction energy will dissipate wastefully in air resistance.” A maglev train running in a vacuum would increase its potential top speed and improve its efficiency level. If such a theoretical evacuated tube transport (this concept had been around for over 100 years now) may be successfully designed and built,  people potentially will be able to travel between New York and Beijing in 2 hours!

In one of our previous posts we have also discussed a similar concept, Hyperloop, by Elon Musk, with the added feature of being solar powered and reaching top speed of 760 mph (1,220 km/h).


The beauty of universal collaboration through open-source is such that information in free-flow form, would enable much to be synthesized, exchanged, and edified quickly. Now the scientists and  engineers at Netherland have also taken on the challenge and incorporated the concepts of maglev, evacuated tube, and solar power, working on the Netherland’s Quantum Train (quantum-locking or quantum-levitation). Quantum Train is essentially the solar-powered evacuated tube transport that will be CHEAP, SAFE, FAST, SUSTAINALBE, and GREEN. The future of Quantum Levitation will enable 2 mm thick 3″ diamter superconducting material to carry  approximately 1000 Kg (a small car). The future will be magical ! Many top notched scientists and engineers are working on this at the moment in multiple countries and we are looking forward to the day when Solar Powered Quantum Evacuated Tube Transport/Maglev Train will be transporting us near 1,800 mph on every continent….perhaps even one day transporting us from one continent to another continent in this magical transport system.The world is getting smaller. I am very thankful that we are living in such a magical and collaborative world, full of wonderful scientists and engineers with visions and willingness to collaborate.

“Solar Tsunami” Shared by the Effervescent Professor Jose Cordeiro of Singularity University during World Future Society 2014

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links and note magenta)


On July 12, 2014, during the World Future Society 2014 at Hilton Orlando Bonnet Creek, Orlando, FL, I caught up with the hopeful  Professor Jose Cordeiro (trained at MIT) of Singularity University, to share some of his optimism about the future of Solar and Renewable Energy. He even used the term, “Solar Tsunami” to demonstrate that our energy future will soon be  that of Solar Energy every where. There is no stopping it for Solar Energy is Clean, Healthy, Every Where, and Cheap. We’re facing an exciting future where there will be solar roadways, solar cars, solar planes, solar trains, solar boats, self-driving cars, and much much more wireless. We will see a future with far more distributed solar power rather than centralized power.

Professor Jose Luiz Cordeiro, the Venezuelen scientist, futurist, economist, engineer, and columnist, is extremely enthusiastic because he is excited about sharing information and being a proactive futurist. In the link below, you can find out the four potential types of attitudes toward the future described by Professor Cordeiro in his TED talk, “The Future Is Not What Is Used To Be: Jose Luis Cordeiro at TEDxRio+20“.  Professor Cordeiro literally effervesces for he is able to fully appreciate both the danger and opportunities our future is availing us. This is a common characteristics one finds in Solar Enthusiasts and Futurists; the thought of potential future free energy and transhumanism simply holds such incredible promises that one cannot help oneself but become effervescent!

Fellow Earthlings, We Need To Go Renewables (Solar-Wind-Water) Quickly!

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links below)
__________________________________________________________________________________________

Updates on our Solar-FIT For Sunshine State petition: 165 signatures strong. We need more! Please help us to spread more sunshine by signing this petition and sharing it with others. It is our shared responsibility to move toward the renewable energy age and Sunshine is the cleanest, healthiest, and least war-prone way to go!
__________________________________________________________________________________________

I’ve been asked by quite a few people, since starting Sun Is The Future, why I would  bother spending so much time working on this project. My response: there are many of us on this planet, who are concerned about the impact of climate change issue, who are worried about the stability and safety of our future generations. Case in point,  I would like to bring you an interview of a nature photographer, James Balog, on a long-term project, documenting the visual impact of climate change even more effectively than scientists’ data or graphs. This amazing body of work is also known as the “Chasing Ice” that I highly recommend

“Chasing Ice” (some call it The Inconvenient Truth) (directed by Jeff Orlowski, photographed by James Balog), capturing melting glaciers

.  Below is the interview with the photographer James Balog and Jeff Orlowski (Chasingice.com)  and multiple links that will help to demonstrate the impact of global warming and why we need to GO RENWABLES and GO SOLAR  QUICKLY:

We need to realize that this is not a partisan issue and needs to be addressed quickly before more coastal cities would disappear or extreme climate conditions appear.

Due to my applied math and engineering background, my natural inclination is always to look for solutions when a problem arises. As indicated in several previous posts where talks were given by Professor Mark Jacobson (you can find it by typing his name in the search box in upper right hand), the need to transition into renewable (Solar-Wind-Water) quickly is the solution. This is the purpose of existence for Sun Is The Future, for it brings not only the sharing of information on solar energy at www.sunisthefuture.net,  interviews and visual information at sunisthefuture Youtube Channel at www.youtube.com/user/sunisthefuture , assistance for entrepreneurs throughout the planet to establish and maintain small businesses in solar energy/renewable energy/energy efficiency/recycling via micro-finance at www.kiva.org/team/sunisthefuture ,  a petition for Solar-FIT For Sunshine State at http://sunisthefuture.net/?page_id=7424 to help encourage more solar installations in state of Florida. And most recently, because some of the meetup groups would not permit me to talk/spread the idea of solar energy use unless I am selling a product, I’ve started  online Sunisthefuture stores (aka Sunshine Online Store & Sunisthefuture Logosportswear).

The exciting thing about being alive now is the fact that existence of all the projects at Sun Is The Future would not have been possible few decades ago. Through collaborations of various internet organizations and social networks, readers/visitors/viewers have come from more than 160 countries. That is why, despite the rate at which our global warming has increased, I am still hopeful that we can reach out to every corner of the planet earth to speed up the transition into renewable/solar energy. But we do need to hurry, for we have been warned by the IEA (International Energy Agency), that our world is headed for irreversible climate change in five years, the world will lose forever the chance to avoid dangerous climate change. What does that mean? Explained below in italicized 2 paragraphs taken from Nov. 2011 post of Guardian :

Anything built from now on that produces carbon will do so for decades, and this “lock-in” effect will be the single factor most likely to produce irreversible climate change, the world’s foremost authority on energy economics has found. If this is not rapidly changed within the next five years, the results are likely to be disastrous.

“The door is closing,” Fatih Birol, chief economist at the International Energy Agency, said. “I am very worried – if we don’t change direction now on how we use energy, we will end up beyond what scientists tell us is the minimum [for safety]. The door will be closed forever.”

Let’s all try to do what we can to transition into the renewable and solar energy age!

~may we all try to reach for the bright and sunny day~

Using the Math and Magic of Origami to Increase Solar Efficiency

Share

If you prefer to listen rather than to read, audio portion of this post is available at: AUDIO (<–Click)

Dear Friends & Visitors/Viewers/Readers,

(Please click on red links below)

I just spent a full day at WordCamp 2012 at Orlando, FL, learning how much more I can improve this site.  Wow, I certainly have much to  do….thanks to all of those WordPress volunteers responsible for organizing this event!  Well done! Much appreciated!

———————————————————————————————————————————————————————

Today’s post is an embellishment of May 7, 2012 post on Solar Future From The Eye of  a Twelve-Year-Old, Solar Cells in 3D .  Life is simply delicious when the confluence of my three hobbies, origami-math-solar, would play a part in our energy future by boosting the efficiency level of solar panel.  For those of you who have been following this site (http://www.sunisthefuture.net) for almost two years, hopefully you have come to realize the three difficult triad historically associated with being the barrier to prevalent implementation of solar energy is: cost, efficiency, and battery storage.  Our previous post in Nov. 27, 2012, reported on dramatic decline in cost of solar energy. I will present to you, in today’s post, an interesting way to increase solar efficiency, followed by next post’s piece on battery storage.

Below is a wonderful presentation by Robert Lang, “The Math and Magic of Origami”, selected from TED talks, demonstrating the use of origami concept in increasing solar efficiency.


Regardless be it from researchers in MIT, Virginia Tech, or the teen William Yuan, they have all utilized the origami concept to dramatically boost the efficiency or power produced by solar panels (ranging from doubling to 20 times or more  than the traditional fixed flat panels, claimed by some researchers/experimenters).  The origami-like 3D solar structure is much more efficient than the flat panels, absorbing more light and generating more power than a flat panel containing the same area footprint.  The idea is that all unused light which has been reflected off one panel would be captured by other panels.  Panels of this type is most ideal in situation with limited space. “This was a fully ‘bio-inspired‘ idea. I was hiking up at Lake Tahoe in California and noticing the shapes of trees, and wondering, ‘Why do they have a given shape over another?'” said researcher Jeffrey Grossman, a theoretical physicist at MIT.  In the past researchers in photovoltaic panels have kept these panels mostly flat to prevent any shadow effect because shadowing would diminish the amount of light panels harvest.  Furthermore, 2D panels are easier to install on rooftops and better suited for large-scale fabrication techniques.  Scientists now use a genetic algorithm in a computer simulation to determine the optimal 3D shape for harvesting the largest amount of light for solar panels. This algorithm creates random combinations of flat, triangular, double-sided panels and analyze them in response to the sun’s movement across the sky. The best ones are selected to be mated to create “offspring”;this process is then repeated for millions of generations to see what might evolve.

A huge advantage of 3D solar panels is that they require no moving parts and generate an even flow of power throughout the day.  In order to achieve this with flat panels, they must be arranged on a tracking system that moves with the sun, “which is a big bummer, since you really don’t want any moving parts sitting on your rooftop,” Grossman said. Anything that moves can break easily and requires more maintenance.  It is exciting that this simple idea will ultimately help to reduce the cost of solar power. We wish much success with these researchers and experimentalists in coming up with the optimal, computer generated, 3D designs.
