Arizona State University Pioneers Solar Structure Installation
Visitors to Arizona State University’s (ASU) Tempe campus soon will be shaded when parking in a lot adjacent to Sun Devil Stadium by an innovative, patent-pending solar structure design that generates 2.1 megawatts (MW) of electricity. This groundbreaking solar installation project marks the first partnership between ASU and NRG Solar, a subsidiary of NRG Energy, [...]
Innovative Method from MIT for Solar Thermal Energy Storage Expected to Make a Significant Contribution to the Industry
Concentrated solar thermal technology works by focusing the sun?s rays onto a heat engine that turns a generator making AC electric power. As with Photovoltaic technology of course we can only make the power as long as the sun is shining. To solve this problem we need to come up with an efficient, reliable and [...]

Engine 3F Efficiency Analysis part 1
In an earlier post I measured 1.05 watts output from my engine 3F using a 69 watt input. This computes to 1.5% efficiency. So where did the other 68 watts go? The following is my analysis of where all the energy went. It won?t be as rigorous as I would like, partly due to lack [...]
