The starting temperature was 80f (27 C) and a full boil was obtained in 90 seconds (+-10 seconds). The dish is a 10 feet (3 Meters) diameter with a large acrylic mirror for the center. Focal length is 5 feet (1.5 Meters) from the base. The mesh panels are covered with Part A and B material from our website and also regular .118 acrylic mirror sheets. The focal point is 1" diameter from the acrylic mirror and 4"-8" diameter from the satellite dish. The vacuum tube holds 20 ounces and it was full.
Very cool Dan! We made a parabolic dish solar cooker from an old 10' satellite dish. For the first year we used old CDs as reflectors. It works pretty well, hot enough to cook marshmallows on long sticks. Next summer we're talking about a broken mirror mosaic. It will get heavy.. I will check out the material on your site.
keep up the good work! Eric

Nice when clear skies. How much heat is captured when overcast?
Must keep tracking the sun. Awkward and cumbersome.
No need to produce such high, dangerous temperatures.

Those vacuum tubes are incredible bare footing you add any collector and they are so powerful they beat most electrical appliances.

Awesome!
I wish I lived right next door to ya'll. I love all of your experiments! Why doesn't everybody love FREE energy? I think it's fascinating (in a low budget, endless possibilities kind of way). I can't wait to see the video from the film crew. At least somebody is interested in home brew renewable energy.
Next time let Denise wear the jacket ;)
