It is possible to harness power from solar energy, to orbit big solar collector, how to collect user on earth.
Posted by admin on Aug 31, 2010
I mean, if we can install big solar collector outside earth to orbit facing to the sun, it is possible, if possible, how can our expert transfer the collected energy to the earth ?
They actually considered this like 20 -25 years ago.
The problem is getting it back to Earth.
If we focus the light beam or use micro waves and send it to collectors;We’ll have to be dead on with our aim.
Can you imagine what would happen if something went wrong and sent a beam through a major city?
You would also have to create large no fly zones to keep planes from flying through them.
Maybe We could use the energy to fuse Nitrogen and hydrogen into ammonia.
Then We could separate them back here on Earth and extract the heat.
Of course that would create a problem also.
What if We had another challenger or Columbia accident while they were loaded with ammonia
How much would it cost to run the entire united states on solar power?

And how many square feet of solar panels would this require? Cite your source if possible please.
Georock is correct that storage would be required. Pumped hydro is the most efficient way of storing power at this level – surplus power is used to pump water to an elevated reservoir, then reclaimed by draining the water through a turbine. The need for storage can be decreased also by carrying the electric grid through multiple time zones so the time that there is no sunlight on the grid is decreased.
CIA figures show U.S. electrical consumption at just over 4 trillion KwHr per year. At about 2000 hours sunlight per panel per year (conservative estimate) that means about 2 trillion watts of solar panel. Retail prices right now are about $3.50/watt, so a one-time cost of $7 trillion would give us fossil-fuel electricity in the states. There isn’t that much solar panel fabrication capability in the world yet. Seems like a better investment than a lot of others we’ve been making at that scale, though.
The area is a bit tricky – the newer thin-film photovoltaic panels will be lots cheaper when the bcome available in bulk (that’s production capacity limited right now) but the take up to 10x the area of the silicon photovoltaics. Figuring in silicon, at around 10 watts/square foot, it’s 200 billion square ft. or about 7200 Square miles. That’s the size of the eastern 1/3 of San Bernadino county, which is mostly Mojave desert.
Another possibility is solar thermal, which uses mirrors to focus sunlight on a boiler. This is a powerplant-sized solution with about the same efficiency as the photovoltaic. Some designs incorporate enough thermal storage to allow overnight continuous operation.
I want to install small size hybrid power genrator with solar & wind on the top of my house?

I have seen mini power hybrid with solar & wind genrator set in Taiwan but forgot the make.
You would be interested on the following guide for the instalation

any good songs to play for a video? 10 points?
Posted by admin on Aug 31, 2010
hey i’m making a video on how oil is bad, it’s ruining our planet so we should turn to solar. any one have good songs/facts about solar energy or oil?
that would be awesome
my ideas are: soak up the sun – sheryl Crow

which one is the best/ any better ideas.
it’s just for a school project…..

Stirling Engines – Solve Energy Needs?

KCET, Public TV in LA ran this story about “Stirling Engine” powered solar electric generating technology. If true, we may be able to kiss nuclear power plants good bye.

Should solar power be the dominant energy-source of the 21st century?
Posted by admin on Aug 30, 2010
Hasn’t solar power technically been the dominant energy-source of all the other centuries?
No, Let’s rely on the middle east oil, Thank God US is dealing with a terrorist country like Saudi Arabia!
What is the cost of a solar power plant?
Posted by admin on Aug 30, 2010
that depends of it’s power. If you want electricity for 3 houses it’s affordable. For 3000 it’s a goverment issue 
What if Cornelius Vanderbilt decided to use wind & solar to power his trains in 1870 & if for steel, Carnegie?
Posted by admin on Aug 30, 2010
…. had used wind and solar instead of coal to fire his furnaces?
Isn’t that what Obama and the Dems are trying to do to the US today?
Yes. They are suckered by the insane eco-bigots who are so deluded they ignore the physical realities of life on earth. They live in a hyper-deluded fairy tale world and are ravaging everything in the desperate, futile effort to pretend it can be realized.
I support practical conservation efforts but I won’t cooperate with the ultimately terribly destructive delusions.
Facts About Solar Energy
Posted by admin on Aug 29, 2010
http://solarenergyhomesolution.com/Free The nuclear reaction in the sun consumers about 4.2 million tons of mass every single second. At this rate, the sun will last another 6 billion years. Earth intercepts only 2 billionths of the suns total energy output. The amount of sunlight that hits the Earth’s surface is 35,000 times the amount of total energy that humans use.
