Peppermint’s Forty2. The solar microgrid – made portable and accessible.

September 6, 2012 in Distributed Power, Solar

Based in Sioux Falls, South Dakota, Peppermint Clean Energy is a cleantech startup developing the Forty2, an integrated solar “Utility in a Box” – powerful enough to run an emergency disaster-relief medical facility, compact enough to be carried by a child. The Forty2, with a name that pays homage to The Hitchhiker’s Guide to the Galaxy’s Answer of the [...]

Mera Gao Micro Grid Power. Solar-powered network systems for rural off-grid villages.

July 6, 2012 in Appropriate Technology, Distributed Power, Solar

The world’s off-grid population – who are also the world’s poorest – not only rely on dirty and unsafe sources for their energy needs (kerosene for lighting, charcoal for cooking), but they are also paying a much higher price for energy needs than their grid-connected counterparts. We’ve seen a number of off-grid projects respond to [...]

Eight19. Transforming lives with flexible solar technology.

June 14, 2012 in Appropriate Technology, Solar

Cambridge, UK-based Eight19 combines an innovative technology (organic solar PV) and an innovative business model (pay-as-you-go solar electricity system) to provide a low-cost solution for clean energy access to rural off-grid communities. Eight19 is a technology company.  They develop and manufacture a novel printed plastic solar cell technology based on organic semiconductor materials.  As compared to the [...]

Solar Impulse. The revenge of Icarus.

May 17, 2012 in Solar, Transportation

I was inspired to approach the topic of low-carbon travel, after reading Sustainable Energy – without the hot air and realizing that no matter how much effort you make in your daily life to reduce your carbon emissions and live efficiently – take shorter showers, turn down the heat, avoid using a car, eat less meat – as [...]

3-D Solar. Up to 20x more power than flat panels.

April 8, 2012 in Solar

Numerous companies – 1366, Bandgap, Twin Creeks, and more – are striving to optimize solar cell efficiency or manufacturing to bring down solar costs. Regardless of the innovative process, the end-result is generally the same: a flat panel that is fixed on a rooftop or other surface. A team of researchers at MIT is considering [...]

SolarFuel. Smart Energy Conversion.

March 23, 2012 in Energy Storage, Solar, Transportation, Wind

SolarFuel, a Stuttgart, Germany-based startup, is developing a Power-to-Gas (P2G) technology which converts wind and solar-generated electricity  into “storable” synthetic CO2-neutral natural gas. The key challenge facing the successful integration of renewable sources (re. solar, wind) into grid infrastructure is intermittency. Renewable electricity is generated irregularly – when the sun is shining or the wind is [...]

Brite Solar. The future is Brite.

March 21, 2012 in Solar

Brite Solar, based in Athens, Greece, is developing 3rd generation photovoltaic technology to produce solar windows for homes and office buildings. Brite Solar’s PanePower Solar Technology is based on Building Integrated PV (BIPV) market, growing substantially from $528 million in 2008 to

1366 Technologies. Solar manufacturing for the 21st century.

November 1, 2011 in Solar

If you know anything about the solar industry (which is likely more than I do), you’ve probably heard of 1366 Technologies.  Based in Lexington, MA and named after the solar constant (not a street address like 1369, one my favorite Cambridge coffeeshops), 1366 has developed a novel manufacturing technique to produce silicon wafers by casting (in [...]
