Comments on: Climate Reporting in Physics WorldClimate science commentary by actual climate scientists...By: Burn boron in pure O2 for car power- November 30, 2011 Considering that fuel cells may be twice as efficient as conversion to electricity via combustion driving a mechanical heat engine, There's no evidence of that. Air-breathing hydrogen fuel cells that are much too heavy per unit power output to propel a car have 41 percent efficiency, based on the delta 'G' of hydrogen oxidation. Lighter ones can and do propel prototype cars, but not as far as hydrogen internal combustion car prototypes were going in 1970s. Look up the BMW 520h. Suppose fuel..http://www.realclimate.org/index.php/archives/2007/02/climate-reporting-in-physics-world/#...

Re 283: I don't know off hand what the theoretical limitations are in lasers or in PV cells designed for concentrated monochromatic light. Also, my asteroid comments were made with humor in mind. Aside from that, I'm not sure which physical laws I've suggested breaking. Of course, many ideas may upon inspection turn out not to be solutions - the more complex arrangements of...http://www.realclimate.org/index.php/archives/2007/02/climate-reporting-in-physics-world/#... |
