Here's a simple experiment. I hooked a 4'x10' solar hot water panel up to just a small (3 watt) pump and a 60 foot coil of 3/8th" copper pipe set down in a tub of water. I wanted to see how effective the solar panel would be at transferring heat through that copper coil into the wate...

It can better be  used on a larger scale. You could also  design flat parabolic "plates"  with mirrors  on a sheet of  plywood  to make powerful mock parabolic dishes.  (In that case only one laser shining straight down is needed) This shows  h...
