Bloom Energy Promises Cheap, Emissions-Free Power From a Small Box | Popular Science - 0 views

  • The Bloom Box idea came from K.R. Sridhar, a former NASA rocket scientist who once built a similar box device to generate oxygen on Mars for future colonists. Sridhar simply turned the concept on its head by pumping oxygen into the box, along with fuel. The oxygen and fuel combine within a new type of fuel cell to create the chemical reaction that makes electricity. There's also no need for power lines coming in from an outside source, and Sridhar envisions the box eventually providing energy wirelessly to homes and businesses. That could do away with traditional power plants and the power grid. Such transformative power may only come about if the Bloom Box fuel cells can work reliably and efficiently -- other fuel cell technologies have proven notoriously finicky. Sridhar makes his fuel cells based on cheap sand-based ceramics, coated with special green and black "inks" that allow for the chemical reaction which makes electricity. One of the simple disks can power a light bulb, and a stack of 64 disks with cheap metal plates in between them can supposedly power a Starbucks. And unlike fuel cells that require pure hydrogen, the Bloom Box can use fuels ranging from natural gas to bio-gas.

    A boxy power plant that could one day produce efficient, inexpensive, clean energy in every home might sound like a pipe dream, but it's the very real product of a Silicon Valley startup called Bloom Energy. Twenty large corporations that include Google, FedEx, Walmart and eBay have already purchased and begun testing the Bloom Boxes. 60 Minutes recently got a sneak peek at this possibly game-changing energy device.

    Here's SOME of the "rubs". How long will the device's last and what are the maintenance costs (if any)? What will the cost of the fuel be and how much is used? Will the manufacturing process "scale up nicely" (and easily) so that "economies of scale" will actually bring the price of a home-system down to around $3-5K? Will the price of the system, its maintenance, and fuel actually come out to be significantly less than the price of "grid delivered" electricity? Without "good enough" answers to such questions, this system may be more of a good remote generation facility than a grid replacement.

Berkeley Lab Scientist - Produces More Electricity Than He Consumes - 0 views

  •  
    To power his home and his car, Greenberg has two solar installations and a solar water heater. They produce so much energy he has dubbed his home the Ordway Solar Power Plant. His solar panels, which sit atop his white roof, generate roughly 7,000 kilowatt-hours annually. His house and his electric car together use about 3,000 kWh per year. That leaves about 4,000 kWh surplus that he gives back to Pacific Gas & Electric every year, enough to power about two-thirds of another typical single-family home in the area.

Delivering Health, Wealth and Water, Drip by Drip - 0 views

  • Solar-powered drip irrigation enhances food security in the Sudano–Sahel documents a field research project which found that: "solar-powered drip irrigation significantly augments both household income and nutritional intake, particularly during the dry season, and is cost effective compared to alternative technologies" Over the decades, irrigation has been shown to greatly increase agricultural productivity. Drip irrigation is spreading rapidly in Africa, with significant benefits. "Drip irrigation delivers water (and fertilizer) directly to the roots of plants, thereby improving soil moisture conditions; in some studies, this has resulted in yield gains of up to 100%, water savings of up to 40–80%, and associated fertilizer, pesticide, and labor savings over conventional irrigation systems" The solar-powered systems, however, look to offer the potential for even better results. From the study on impacts of PVDI systems it was reported: "The women’s agricultural group members utilizing the PVDI systems became strong net producers in vegetables with extra income earned from sales, significantly increasing their purchases of staples, pulses, and protein during the dry season, and oil during the rainy season. Finally, survey respondents were asked how frequently they were unable to meet their household food needs. Based on the frequency and most recent incident, households were assigned a food insecurity score ranging from zero (no problems during the previous year) to one (perpetually unable to meet food needs). This score changed significantly for project beneficiaries, as they were 17% less likely to feel chronically food-insecure. In short, the PVDI systems had a remarkable effect on both year-round and seasonal food access."

Nanoengineered batteries could enable the next generation of high-power rechargeable ... - 0 views

  •  
    Batteries for all-electric vehicles must deliver high power densities in addition to high energy densities, Koatkar said. These vehicles today use supercapacitors to perform power-intensive functions, such as starting the vehicle and rapid acceleration, in conjunction with conventional batteries that deliver high energy density for normal cruise driving and other operations. Koratkar said the invention of nanoscoops may enable these two separate systems to be combined into a single, more efficient battery unit.
