Um... no. No, no, and no.

This is NOT a superb idea. If someone would read my post, I explained that the conversion process from regular light to a laser would only use up energy, leaving you with less than you had to begin with.

This theory is a very intriging statement. I think it would be possible to in the near future with us breaking into Laser Eye Surgery and all. Before peopel thought they would never be able to control the eyes, Now we can almost rewrite the eyes. Just think that we will be able to do alot with Solar laser Optics as an energy source. I think its the way of the future. Great job man!

Your idea is interesting but there are much limitations in it as there are in any of those other energy sources you had described.

Firstly, to convert solar energy into a concentrate beam would require a tremendous amount of energy, as someone earlier had stated. The ratio between the energy output and energy input might actually be overbalanced towards the input energy side, and thus would mean worthless energy output that would require too much resources and energy to create any worthwhile amount of energy.

Secondly, to actually produce any worthwhile amount would require a giant apparatus system. This would require a great amount of resources that would also require a location relatively safe enough for concentrated energy waves that are carrying as much energy as gamma rays, if your thoughts on lasers zapping people are true. The solar cells you'd have to create would have to be strong enough to take this energy in; where will this indestructable material come from?

Just some thoughts.

No theres nothing wrong with being ambitious, also if I may congratulate you on your idea (which to be honest, is a very simple one I'm surprised no one else has thought of it before). I must also admit that I have a very limited knowledge of how LASER's, but I sincerly hope that you manage to perfect this technique and further refine it so that it can be used to provide a large protion of the power we need.

I agree with this. I think it's a good idea.

It seems it would work

but the energy required to have an effective laser is a lot, thus will take hours of energy collection just to have the laser run for a few seconds

I have a question and a correction. what is the efficiency of this converter? because with just polarizing light you can lose 50+% of the transmission from the sun right away. experiments with polarizing film is a great example of this. does this added lossy step actually not cancel the gain in efficiency of the solar cell? this is a really interesting subject. I'd like to here more about the physics of the matter.

the correction is:

Not all nuclear energy sources are a double edged sword. nuclear power is very safe but there are the potential problems with fission technology(radiation,meltdown etc.) the work i'm going to be doing is on fusion technology which has none of these potential hazards. if there is an error the production of hydrogen stops (lack of power to run the reaction) and the fusion core reaction also collapses due to lack of hydrogen input. even if the safety catches ALL fail there may be an explosion but no radiation hazard.

fuel cells are limited by the reaction they use. it's quite slow. it also requires fossil fuels to make these work. ethanol is a non-option because to hold our current energy needs we would have to cover three earths completely with corn which isn't feasible.

You don't have to bash into his post, he has a nice idea and the way he is gonna use that idea is going to show us how efficient this way of generating energy is.

Nice read, I hope you'll get this to work, humanity will need it in the short future <_<

You wouldn't need a couple acres of mirrors to come up with enough energy check out this video. It takes 2 square meters of sunlight to melt anything so what's saying we couldn't harness that energy in a different way IE: through solar cells or through steam generation
