Finally got started on lining my dish with mylar, that's a ten foot
satellite dish :-). What kid wouldn't have fun with a ten foot
magnifying glass that weighs less then 50lbs.
I decided I had to check out the "proof of concept" in my driveway.
Hilarious ! With half of the dish manually focusing I can melt light
plastic objects instantly and cause a heavy paper (dog food) bag to
smoke in seconds not even with a sharp focus. :-)
Gotta get some shades b4 I go blind.
Photos should show up soon on my website ... http://www.pluggedin.ca
just look for the "water heater from hell" project.
I have a dish waiting in the weeds for me to get started with it on a
project like yours. Please keep me informed of your success.
