I have to think new ideas had problems that were thrown away because they realized there was a problem. Is there a methodology for documenting and subsequently searching out these cases? Because I have to think there were cases of ideas conceived and then tossed for problems, and then reconceived and implemented without realizing there were issues with the idea… -
Well. The plot thins. It appears Gene Hackman's wife died up to a week before Gene, from hantavirus pulmonary syndrome. Gene may not have been aware of her death due to advanced Alzheimer's, but given where his body was found, it's possible he was finally seeking help when his heart gave out. A sad story.

I bet a wet dress rehearsal would have caught these issues… -
I thought hydrogen burned blue if not colorless. Running extra rich?

The biggest advantage I see to home PV installations is redundancy in case of disasters disrupting the utility supply, if a major storm destroys transmission towers, for instance. Available power may be limited in such cases, but it’s better than having the contents of fridges and freezers spoiling during a lengthy outage, or having to find fuel for generators. Of course, no solution is perfect.

I see solar as complementing baseload on hot summer days, using the excess solar to power air conditioners. But I suppose it would be little help in the evening and none at night, without some form of storage. I suppose a liquid-based hvac system could pre-cool a tank during the day when solar is plentiful, to be circulated at night to keep things cool. Sort of the opposite of concentrated solar-thermal power, which heats molten salts enough to keep generating power at night, but that only really works in areas with few overcast days. Modern photovoltaics still work on overcast (especially lightly overcast) days, when it doesn’t even really matter which way the panels are pointed.
