Low temperature steam engine now available for residential CSP

The missing link in residential scale solar and other heat generated electricity has been a practical low temperature, low pressure steam engine. Now 230 - 300 degF heat can create realistic amounts of electricity.

atitude Solar in Maine has developed a concentrating parabolic trough collector in panel form to compete head on with evacuated tube collectors in price and performance. We then wanted to use it to generate steam to drive a steam engine-generator. Experimenting with conventional steam engines showed how extremely inefficient they are with low temperature 50 - 100 psi steam. We have solved this problem and it is now available for purchase for use with our solar collector, any evacuated tube collectors, or even with just a tube coil in your woodstove or oil furnace.

LG Solar Unveils NeON R with Enhanced Aesthetics and Energy Savings

The NeON R module features "Back Contact" cell technology delivering an entirely black panel that is aesthetically pleasing and energy efficient. The cell's seamless, surface blends perfectly into nearly all rooftop designs while the module's electrodes are positioned on the rear of the cell. Using LG's N-type cell structure, the panels produce 365W of energy, up to 7.3kWp, compared to 5.8kWp of the p-type cell. The module's new design minimizes LID, thereby delivering a longer lifespan and increased energy output.
