Solar panels today can capture 20% of the suns energy. That means we could potentially get 5X (!) the amount of energy if we focus on how to do it. 20% efficiency isn't great, but it can easily power a home & electric car. At 75% efficiency, it BLOWS AWAY the cost of oil, coal, and (so called) "natural" gas. If we reach 75% efficiency, it's over for fossil fuels. This is one of the best areas to focus on - Let's get to 75%!!! Build things in your garage, experiment, study, invest, encourage!

if its stainless steel, its not wool.

Make A Telescope Out Of It That Would Be Huge

If you can't put this kind of vessel under pressure, and you can't drink the water from the boiler because of contamination from the steel wool, what would this purpose be?

All I know is the scary suspence music at the beginning is from the creepy ghost movie "The Others" so random how I recognised that. Did anyone else...?

@trumpsahead The fuck is wrong with you.

how you make the mirror ???

Darn, I missed the death ray. :-(



The opening of this video saw chemtrails in the sky. Could you bring down a plane with this? Maybe four or five almost flat mirrors long focal lengths. Would that work?

@trumpsahead no, you would need 2 sq miles of perfect mirrors to simply illuminate a target at 30,000 ft, up there, where the ice condensation clouds are:-) Even then, the focal point would be so scattered, the pilot would not even notice you. It would look like a shiny lake on the ground from the air.
5:1 dish diameter to focal point is the absolute maximum, up to about 200m focal length, after that, impossible.

These mirrors look very cool... But can you please help me. Other then for some parlor trick or science show, how can I use this on a daily or weekly basis and conserve energy? And when I say use them, I mean in an easy, user friendly way.

@the43k The best way is for cooking or solar heating water through a closed loop system for a heat exchanger. The second requires tracking and mounting.
