Alternative energy solutions are a topic of intense interest worldwide. Research and development into new methods to generate and harness power continues although some tend to forget that there are already some pretty viable solutions readily available. Just look at...

Nice!

I always have wondered how wide should a "photocell belt" around the world be in order to provide energy for the population.

Should have a farm of 100km's square in orbit... never any down time. pure unfiltered power.

It has been considered. The biggest problem with this is how to transmit the power to the ground in a safe manner. It is not an easy task; if the power were constrained to a beam, it would fry virtually anything that strayed into the beam.

[SIZE=13px]first, how to transmit power to earth? Second, how much it will cost to make 100km square? making even less 10km square farm on orbit would cost as much as the cost when you making bunch of nuclear powerplant (include several years of maintenance cost) on the ground, and that's more cheaper and even a single nuclear powerplant can generate electricity several folds than your 100km square orbit farm even unfiltered![/SIZE]

Several mains distribution boards, all plugged together end-to-end.

Hmm - but nukes are ultimately impractical, not just dangerous. Qv Germany, where the nuke shutdown hasn't been an economic disaster at all. An article in the Bulletin of the Atomic Scientists titled "The German Nuclear Exit," shows that "the nuclear shutdown and an accompanying move toward renewable energy are already yielding measurable economic and environmental benefits, with one top expert calling the German phase-out a probable game-changer for the nuclear industry worldwide."

Yes, you're right. I'm just pointing out that how expensive making orbital solar panel.

Most people are confused of the physics of earth. The most light is not at the equator but past the latitudanal level closer to north and south poles where in some cases you have daylight 24 hours. That is where the solar panels should be considered. Also wireless energy transfer. Teslas invention that got lost or suppressed by oil companies. So they can play with energy supply to create artificial demand and enery crisis.

While the guest above remind that people got confused about physic of earth that most light is not at equator but past latitudinal closer to north or south poles, this person forgot that solar power not just need most light/sun rays, but also the intensity of the light, the ambient temperature on north/south poles should be considered too before you make some big solar powerplant there. I know this, based from my friend experience when building remote research compound there supplied with solar power
