Solar electric energy is electric power generation from sunlight. It could be direct to PV - Photovoltaic, or it could be indirect. An instance of the indirect type is concentration of solar power, where the energy of the sun is concentrated to boil water used to generate power. http://www.plumbarena.co.uk

This is great for legacy systems, but given the cost of energy, it is a poorly planned new design that could effectively utilize this technology. Real energy savings can be had with heat pump water heaters (cool the house, create hot water simultaneously), or the University of Michigan using the Great Lakes for a heat sink and cutting their air conditioning bills by about $500K per month.

Also this must use true waste heat as a source. if not then increasing thermal conductivity will lower the mother ships efficiency. This would negate any power produced by the parasitc system running of the exaust heat.

I posted this six days ago; and it's been nothing but crickets chirping.

Bill Schweber would have caught this. Where is he?

For the record, when the source resistance is zero, the efficiency ? is 100%; while when in maximum power transfer conditions, the source resistance = the load resistance, the efficiency ? = 50% i.e. the voltage drop and hence the i˛R power dissipation is equal across the source and load.

FALSE: Electrical efficiency ? ? R(load)/R(source ("TEG")) ? = R(load)/[R(load) + R(source)] It's unbelieveable such a fundamental error could make it past the editors and be published in EETimes: A cursory glance would show that if the source resistance is less than or equal the load resistance, the efficiency ? would be =1.0 Dan Schwartz Editor, The Hearing Blog http://www.TheHearingBlog.com

Like many of you, I was saddened to hear the news of Leonard Nimoy's death. His Star Trek character Mr. Spock was an inspiration to many of us who entered technical fields.
