1 Watt Stirling engine driving high-power LED

First let me say I will display this engine and generator at the Maker Faire in San Mateo, CA on May 21, 22 so you can see it running if you are there. The above video shows a one-watt Stirling engine driving a one-watt LED. Conversion efficiency is not too high so I’m only driving [...]

Time to Build! A First Look at ?The Initial Plan?

All, Its time to let actions speak louder than words. We’re going to build the first ever space-based solar power satellites! I made this announcement at the International Space Development Conference and again at the New$pace (properly spelled with a dollar sign) conference in Washington D.C. this summer. Now it’s time to let you in [...]

Multijunction Solar Cells

Multijunction solar cells have long been used in space. Solar cells are well proven in space as a fairly reliable and stable source of energy, capable of running very long time. The primary danger for solar cells in space is cosmic radiation and meteoric dust, causing erosion of the surface of silicon cells and limiting battery life. Multijunction solar cells have multiple layers and have efficiencies higher than single junction cells. They consist of a 3-5 semi conductor for each layer.
