I have a lighting fixture above the bathroom sink with three light bulbs in it. Two have burnt out. Before I replace them, I want to know, theoretically, if I will save money on electricity by using only the remaining one. Does the unit pull less electricity if one of its bulbs is burnt out? Or does it pull the same amount of electricity every time the switch is "on," no matter what?
Thanks.

I’m looking a battery for use with solar power and it has the following specs.

Volts 12
Capacity @ 20-hr rate 120
Capacity @ 100-hr rate 145

How does this translate into running a 1000 watt appliance and how long you can run it with this battery.

I live in an area where a power company uses wind generators successfully. I’d be looking at about a 1.8 kw generator in an area where electricity is expensive. Initial cost is K. Would I be better off waiting a couple of years for newer, better, cheaper wind generators?

Anyone with a home of over 10,000 square feet must modify the home to be powered solely on solar power or wind power.

After all, every little bit helps, and people who live in 10,000 plus square foot houses have huge carbon footprints due to their heating and power requirements. If every house over that size was powered by green energy, it would definitely reduce pollution, dependence on oil/coal, etc.

If you support efforts to reduce carbon emissions, do you also support this suggestion? If not, why not?
I’m not suggesting that we allow carbon offsets. I’m suggesting that if Global Warming is real, then Al Gore and Sheryl Crow and others who live in giant homes should have no issue with modifying them to be completely green. No credits available.
smcgilli….. you must have missed my point.

The people clamoring for us to use one sheet of toilet paper, and turn the heat down to 67 degrees, live in 10,000, 15,000 and 20,000 square foot mansions. My suggestion is, if they are right and global warming is going to kill the planet, then they should have no objection to turning their luxury homes completely green. Right? Wanna bet how fast they’d sidestep this….?
sarge — you missed the point too…. you’re talking about what’s "fair." What would be "fair" is if Sheryl Crow and Al Gore HAD THE SAME CARBON FOOTPRINT AS YOU AND ME. People in 10,000 square foot homes in Malibu, and private villas, and airports in their front yards, are telling you and me that WE have to spend money greening out homes, but they don’t green theirs. WE have to drive hybrid cars and bio-diesel, they say - but they fly in jets 100 times per year — WE have to use one square of toilet paper, and THEY make sure their entourages and themselves are bathed in luxuries while on "tour" and making movies (which are pure luxuries - and major pollution sources).

And why?

I’m doing something for school about having wind energy in S’pore. Just liked to hear what you think. Thanks.

Thus, killing two birds with one stone. It could be financed by NASA’s budget and wind power investors with government assistance.
Airborne wind turbines can be attached and reattached to accommodate space vehicles, since they can stay aloft with their own power.
Since wind turbines function more efficiently at higher elevations, but require a tether . It seems to e that the tether could be multi functional and shared by both technologies.
NOPLATE:–Yes I read about the nanotubes, but I thought they had already worked it out. —My bad, but I hope they can pull it off.
I read that LiftPort was able to send a naotube tether up 1000 ft., and is confident that they can go a mile. Still a long way to go, but hopeful.
BLAMAY:—Intreasting. —Can you explain how the electricity is produced ?
(Sp) interesting.

I am thoroughly confused on this question.

Millikan’s experiment measures the charge of an electron by suspending charged oil droplets in an electric field. If an oil droplet with a mass of 3.35 × 10–15 kg has the same charge as an electron. What electric force is required to balance the weight of the oil droplet?
