solar generation of electricity may be a scam, we were told from two sources.
So we're investigating by experimention, field trips, sales pitches, and
fast neutron's post piqued our interest in solar generation of
Santa Fe, NM
From actual experience, wind farms produce 1.2 watts per
square meter. Solar Thermal and Photovoltaic methods capture 5 to 6 watts per
square meter. There is no economy of size in either technology. Dividing the
watts you need by those values gives the land area in square meters needed to
produce the juice. The numbers are astronomical
[Bill's post just before fast neutron's may have caused above post?
MorganStanley VP was next stating that large-scale solar generation of
electricity is a fraud.
MS lost $24 with the bankruptcy of
Aviation. Guess was going to be more careful about possible investments in
New Mexico solar ventures.

|billp37 a 10 MW solar PV array takes up about 7
acres. no long term damage to land. That is 10,000,000 watts / 28,000 sq meters
= 353 Watts / sq meter no water resources used. Germany has 30 GW's installed =
30,000 MW / 10 MW x 7 acres = 21,000 acres In Ontario, Canada we have 105,000
acres of golf courses As well most solar goes on un-used rooftop space. China
figures they have 100 million sq ft of flat roof commercial. equal to 23 GW's.
Solar produces power at 31 grams of CO2 over lifetime, nat gas 600 grams/ kwhr.
Most studies are done by people that do not fully understand the technology.
Response: none :)

Albuquerque Journal appears to be pushing large-scale solar
generation of electricity?
Where do journalists come from? They are
manufactured in America's universities in a liberal arts curriculum.
Whitman college taught me:
Liberal arts 'educated' 'think' different. Most
memorize, speculate, emote, then interpret.
Logic and reason does not
work with them.
Ignoring facts is a liberal arts ploy.
scrutiny of them trying to ignore facts can get them to deal with facts.

Solar panel .01 V, battery 1.34 V, current into LED
1.26 V should be at the anode of the LED. But why the
voltage is present when the solar panel is charging the battery is puzzling. A
mistake in test point placement?

61.6 mA at 1.34 V is applied to AA NICD battery by solar panel

Solar panel voltages are suprising high even with dim light.
But little current it output.
