How do you transport solar power tower energy to a building that is 4 kms away?

And is an area of 1 km^2 for a solar power tower enough to produce energy for five houses? can you make an approximation of how much it could supply?

If you want the heat energy, consider tracking mirrors at the site and solar collectors on the houses. If you want electric energy, that area is enough to support a traditional steam turbine, much more cost-effective than photovoltaic. That area is about 15 times the area that Solar One used to generate 10 megawatts in the Mohave Desert, so it could supply a theoretical maximum of 150 megawatts during peak sunshine. That’s probably enough to match the demand of about 25,000 homes. Best bet would be to feed it to the electric power grid.

How can I power a couple small appliances using solar power?

What would I need to power a small fan, some LED lights, ect in my home, without spending hundreds or thousands of dollers? How would I set it up? I think I would need a Solar Panel, a AC/DC converter or some kind, and a Battery?

Any Help! Thanks!

Look up solar solar power supplies, battery charger and solar charger on the Internet.Lots of good information there.

You will need to know how much current you will be drawing, the number of hours you will be using power, the rating of the power supply and the insolation ( this is spelled correctly) from insolation tables on the Internet.

How to prevent solar power lights from getting stolen?

Although they haven’t been stolen YET, I expect my solar power lights to get stolen sooner or later. I was wondering if you know a good way to prevent them from getting stolen (other than moving them somewhere else or not putting them out at all)?. Oh, and i would not like to make a cement foundation for them or buy different ones -lol. Any help will be greatly appreciated
oh, and please make the answers reasonable, don’t be crazy.

Drill a hole through the base of each one, just below ground level, and string a plastic-jacketed steel cable through them all; then bury the cable in a shallow trench between the lights.

Could Solar Power work more effectively if the solar rays were magnified?

If we focused the sun’s energy like a magnifying glass does into the solar panels, would this generate more power at all?

No, it would not. If the magnifying glass is the same area as the solar collectors, then it would be the same amount of energy the solar collectors would be gathering without the magnifying glass.

In a way it would be cheaper, using cheap mirrors to focus the sun’s rays onto a smaller solar collector surface area. And solar collectors are far more expensive. But as to more power? No.
