It is not the point, because the aim is not energy self-sufficiency. The aims are to produce the energy needed at the most economical cost, and also to do so in a carbon neutral fashion. Rooftop solar is a massive low-hanging fruit in that regard. Batteries, not quite so much, but they're getting there. Some of our friends have invested in batteries, perhaps because they value carbon-neutrality higher than we do. > The other is that it takes up > too much area because it's too dilute; even Dyson spheres have that problem, > they produce a huge amount of power but they need a gargantuan area to do so. > > > > You have warm mild bits too, like Florida, or southern California. > > > I know from personal experience that if it wasn't for Willis Carrier's > invention of the air conditioner there is no way Florida would be the third > most populous of the 50 states, even in mid winter it's not unusual for the > temperature to be in the upper 80s (fahrenheit) with very high humidity. > Everybody has air conditioners, the state should be renamed "Carrier".

But only for a few days in the warmest month of the year. I have visited SoCal and NoCal many times - the temperature range is pretty similar to here actually. We're lucky that we live by the see: close the doors and blinds during the day when it is hot, open them in the evening when there is a cool sea breeze. Yes - in the western parts of our city, aircons are more essential. but again, only for a few days a years. And without Carrier I don't think Texas would be the second most > populous state, and Arizona wouldn't be the fastest growing. Perhaps so - but running the aircons when solar generation is at its peak, and temperature are at their peak works well. Solar makes a lot of sense for those states. > > John K Clark See what's on my new list at Extropolis > wca > > eex > > > > > > > -- > You received this message because you are subscribed to the Google Groups > "Everything List" group. > To unsubscribe from this group and stop receiving emails from it, send an > email > to everything-list+unsubscr...@googlegroups.com. > To view this discussion on the web visit https://groups.google.com/d/msgid/ > everything-list/ > CAJPayv2deya%3DE_kRwtcbsHi9ie_yrUTGSpH-uKmmz8YAW9Cu9Q%40mail.gmail.com. -- ---------------------------------------------------------------------------- Dr Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders hpco...@hpcoders.com.au http://www.hpcoders.com.au ---------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Everything List" group.
