I believe last night was the first time it aired, and I'd like to know your impression of it.

Please grade it A, B, C, D or F, and offer a brief (or lengthy, if you wish) comment.

Also, please say something about your own background so I'll know whether you're an insider or an outsider to the welding industry.

I'd like to run a fan (12 volt .72 amps) from a charged 1 Farad Cap but don't know how to calculate the time it will last! So far my crude math yields 190 days! Yeah right! I'd prefer the math so I can see what a 5 F would do etc... Plus I'd learn a bit! Thanks!

And could insulated water tanks be large enough to retain enough super heated water to generate steam to power the generators be used to act as a buffer so that through the night and on low light days electricty production would be steady without varible output allowing for steady production 24/7/365 if it was sited properly? Would this greatly lessen solar powers twin main faults of expense and inconsistency without the need to wait for cheaper batteries or new more affordible photovoltaic solar panels to be invented or built?
