"It's about seeing the world as what it can be and not what it is" K.R. Sridhar, inventor of the Bloom Box says. Any company who starts with that kind of philosophy has my backing. Originally designed for NASA, the Bloom Box was re-engineered to be a stand-alone power plant in a box. The goal is for consumers to be able to purchase a single Bloom Box for about $3000 for their backyard or basement, which could then power an average American home. Bloom Energy, the manufacturers, estimate that customers could make up the initial purchase cost in 3-5 years with money saved in energy production by the Bloom Box.
The Bloom Box takes in oxygen, and combines it with a fuel of your choice to produce electricity. Fuels can be fossil, like natural gas, or renewable, like gas produced from landfills, or solar power. I'm still a fan of the Bloom Box even when using fossil fuels, as they use half as much fuel to provide the same amount of energy as conventional methods. See the full story on 60 minutes here.
