Solar Sunday is my weekly roundup of renewable energy and energy efficiency news from around the web.
“For entrepreneurs, energy is going to be cool for the next 30 years,” he says.Optimism about creating a “Solar Valley” in the geographic shadow of computing all-stars like Intel, Apple and Google is widespread among some solar evangelists.
“The solar industry today is like the late 1970s when mainframe computers dominated, and then Steve Jobs and I.B.M. came out with personal computers,” says R. Martin Roscheisen, the chief executive of Nanosolar, a solar company in San Jose, Calif.
Nanosolar shipped its first “thin film” solar panels in December, and the company says it ultimately wants to produce panels that are both more efficient in converting sunlight into electricity and less expensive than today’s versions. Dramatic improvements in computer chips over many years turned the PC and the cellphone into powerful, inexpensive appliances — and the foundation of giant industries. Solar enterprises are hoping for the same outcome.
What do you get when you combine the innovation of MagLev technology with solar power, hydrogen fuel, and a futuristic aesthetic? The Interstate Traveler Hydrogen Super Highway, or the Traveler- a ground-breaking solar powered, hydrogen-fueled, zero emission mass transit system that would carry everything from people to cars in sustainable style and carbon neutral function. The construction is set to begin this year, and would connect Ann Arbor and Detroit.The highway is made up of a slew of systems called the rail conduit cluster and will provide a comprehensive integrated system of the public/private transit system and municipal infrastructure network. It would serve as public transport system AND distribute electricity, potable water, liquid waste, fiber optics, hydrogen, oxygen, and fuels.
The public transit component would combine high speed magnetically levitated (MagLev, which we’ve seen in wind turbines before) cars running on parallel magnetic rails, laminated solar cells, and the conduit cluster that would be used to distribute electricity, water, fuels, etc. (It has been projected that each mile of rail would produce about 844,800 watts of electricity per hour at peak time using the solar energy). As for fuel, hydrogen would be used in fuel cells, internal combustion engines, micro turbines and other energy conversion devices to generate power.
The greenies among us will love this: the Strapya mini solar cell phone charger! Smaller than an iPod, this device only needs to drink up 6-10 hours of sunlight and then it serves as a completely dependable backup power source for your cell phone. The mini solar charger hooks up to your phone via an adapter and offers up to 3 hours of energy on the go.
Jeffrey Inaba and C-LAB have created this mandala of consumption, refuse, and plastic waste, with one side dedicated to the “hydration compulsion” that helps puts millions of one-use bottles in places bottles aren’t meant to be.
Sponges that soak up carbon dioxide could provide a new weapon in the battle against global warming. These materials hold promise as filters in power station flues and vehicle exhausts, capturing the gas before it can reach the atmosphere and affect the climate.Researchers at the University of California synthesised a range of new sponge-like substances with pores just the right size to trap molecules of CO2. The most efficient of them can absorb 83 times its own volume of the gas.
Once the sponge is full, the gas could be stripped out for disposal in large, natural caverns deep underground or beneath the seabed. The sponge can be filled and emptied indefinitely, simply by varying the overhead pressure.
The hope is that the sponge will make carbon capture and storage more attractive and cheaper than at present.
Dance your iPod to full charge
A nanotech invention by a US research team offers an intriguing glimpse of the future: slip on some nanowire-embedded clothes, plug your MP3 player or cellphone into them, and as you dance or walk around, your outfit generates enough power to run the gadget. More details on how the fabric works, and some nano-imagery after the jump.
New Record in Solar Efficiency
On a perfect New Mexico winter day — with the sky almost 10 percent brighter than usual — Sandia National Laboratories and Stirling Energy Systems (SES) set a new solar-to-grid system conversion efficiency record by achieving a 31.25 percent net efficiency rate. The old 1984 record of 29.4 percent was toppled Jan. 31 on SES’s “Serial #3” solar dish Stirling system at Sandia’s National Solar Thermal Test Facility.The conversion efficiency is calculated by measuring the net energy delivered to the grid and dividing it by the solar energy hitting the dish mirrors. Auxiliary loads, such as water pumps, computers and tracking motors, are accounted for in the net power measurement.
“Gaining two whole points of conversion efficiency in this type of system is phenomenal,” says Bruce Osborn, SES president and CEO. “This is a significant advancement that takes our dish engine systems well beyond the capacities of any other solar dish collectors and one step closer to commercializing an affordable system.”

Yikes! That’s scary.
