Intersolar North America 2015, In San Francisco, With Intention

Share

Dear Friends, Visitors/Viewers/Readers,

Permanent art installations from Janet Echelman, Kendall Buster, Norie Sato, Charles Sowers, and Walter Kitundu of San Francisco (SFO) international terminal in Terminal 2, formerly known as the "Central Terminal" replaced Rotunda A as SFO's international terminal in 1983.

Of all the photos I took during the trip to Intersolar North America at San Francisco, CA, I find this one (above) truly reflects the spirit of San Francisco. Take a look at how this piece of sculpture by Janet Echelman is described in wikipedia:

Echelman transforms the terminal with fictional nature that subtly engages viewers with real and imagined natural forces. Her sculpture installation cuts three round skylights into the ceiling, from which descend delicate layers of translucent colored netting to create three voluptuous volumetric forms. A series of shaded outlines below are embedded into the terrazzo floor, reflecting the precise shadows that would occur on the summer solstice if the sun could penetrate through the roof. During the day, sun streams through the skylights to cast real shadows that interplay with the fictional shadows in the floor. At night, the artist’s program of colored lighting makes the sculpture glow from indigo to purple, magenta to red-orange. Computer-programmed mechanized air-flow animates the fluidly-moving sculpture at different intervals throughout the day, as if the wind could magically flow through solid walls.

The artist achieved the sculpture’s physical presence by braiding fibers and knotting twine into sculptural netting suspended from powder-coated steel armatures. Despite their large scale, more than 120 feet in circumference for a single form, her sculpture is experienced as ephemeral and weightless. Visually, the sculpture evokes the contours and colors of cloud formations over the Bay and hints at the silhouette of the Golden Gate Bridge. Aesthetically, the sculpture looks both backwards and forwards, drawing its color from the heyday of psychedelic music, the Summer of Love, and San Francisco’s prominence in the beat poetry movement, while also referencing the contemporary bay area as a hub of innovation and interconnectivity for the world of technology.

There is definite intention behind how and why San Francisco is such a hub of innovation and interconnectivity for the world of technology. I have personally observed, on more than one occasion, how San Francisco network had actively gathered/netted in talents from other parts of the USA and good part of the planet earth. On this particular trip, more than ever, I have gained so much information, hope, and optimism for the future of solar industry and technology during Intersolar North America 2015, that I can truly appreciate such netting mechanism radiated from this little area of approximately 46 sq mi. That is why the artist/sculptor Janet Echelman from Tampa, FL , has her sculpture displayed in San Francisco International airport terminal 2 instead of in Tampa, FL.   In the short 3-4 days of Intersolar North America 2015, more than ever before, I can see the future certainty of Solar Tsunami. Coming from a background of mathematics and engineering (civil and mechanical), I’ve gained much of my understanding for the power/energy industry by having an in-house (hubby) technical advisor with electrical engineering background. What seemed to me, intuitively, the natural solution for Energy-Pollution-Economy-Climate Change-International Conflicts during my freshman year in college more than three decades ago, the Solar Energy, will finally be in the main stream!

There will be a series of posts and videos from Intersolar North America 2015 during the remaining of this week and good part of the next week demonstrating how Solar Energy will soon be in the main stream. World wide, we have Germany to be thankful for. USA wide, we have CA and San Francisco to be thankful for.

~have a bright and sunny day~

What Is Solar Cell (5)

If you are in favor of renewable/CLEAN energy, please sign the petition page showing support for FIT/CLEAN Program at http://sunisthefuture.net/?page_id=1065 Thank you.

Dear readers/friends, I hope you will stay with me for 3 more posts (up to What Is Solar Cell (7)) before we move on to another topic in solar energy. Thank you for your patience.

In the previous post, you have seen that Boron and Phosphorous may be used to as dopping material to be added to Silicon in the process of making semiconductor material for solar cell. But there are also other alternatives.  As a matter of fact, instead of silicon, gallium arsenide (GaAs) is another possibility.  GaAs based multijunction devices are the most efficient solar cells to date, reaching 42.3% by the triple junction metamorphic cell.  High-efficiency multijunction cells were originally developed for applications such as satellites and space exploration.  Triple junction GaAs solar cells were also being used as the power source of the Dutch four-time World Solar Challenge winners Nuna in 2003, 2005, and 2007.

Scientists and engineers are constantly looking for alternatives that would help to increase efficiency and decrease cost.  Most commercially available solar cells are capable of producing electricity for at least 20 years without significant decrease in efficiency.  Typical warranty given by panel manufacturers is for a period of 25-30 years, without having output falling below a specified percentage of the rated capacity. So, there are products and technologies that need to be tested and validated.  In U.S., NREL (National Renewable Energy Laboratory), located in Golden, Colorado, established in 1974 and began its operation in 1977 as the Solar Energy Research Institute, tests and validates solar technologies.

Keep in mind that there are three reliable certifications of solar equipment: UL, IEEE, and IEC.

  1. UL: Underwriters Laboratories Inc. (UL) is an independent product safety certification organization established in 1894 and has its headquarters in Northbrook, IL.
  2. IEEE: Institute of Electrical and Electronics Engineers or IEEE (read I-triple E) is a non-profit professional association dedicated to advancing technological innovation related to electricity. (45% of its members are located outside of US).
  3. IEC: International Electrotechnical Commission is a non-profit, non-governmental international standards organization that prepares and publishes International Standards for all electrical, electronic, and related technologies.

Now, I have a clip for you at http://www.youtube.com/watch?v=sRqmTpozPYA or simply click below:

 

Stay tuned at the same bat channel…more will be in store for you…
