Dishin' out the Joules per second.

Test of my heat source project. When done it should give ~600 Watts of hot goodness. This test should be about 500 Watts. I'll meter the calories soon.

hey, what sort of budget did you have for building this thing?

[TalksWithDirt]

@peternisbet The Satellite dish was from Craigs list, Free. The mirror stock was from Craigs List, so it was free too. THe glass cutter with the el-cheapo glass cutter from Home Despot and was $5.00. But it took some time. I'm about to start making a boiler and power platform for it. Hopefully if I can get 60 Wt electrical out of it, I can make a 'Solar Powered Movie'.

Ingenious, you think a setup of magnifying glasses could be plausible?

[TalksWithDirt]

@freakman420 It would be very difficult. Power extraction, in this case thermal concentration, is a function of cross section area. A magnifying glass would work great, as any unfortunate ant colony living near a young child will tell you. But there is in difference between a magnifying glass or a satellite dish. The available power is the same. However gluing a bunch of mirror squares on a sat dish is much easier than grinding a huge lens.

i dont get it.

[TalksWithDirt]

1 Joule (Thermal) has the ability to raise the temp of 1/3rd of 1 gram of water 1 deg celcius. So this dish with mirrors could raise about 1.5 kg (Or a 3/4 full soda bottle) of water 1 deg C. Or almost 2 deg F. Every second.

It's an old satellite dish ..... Soooo... Dishing out the Joules per second.

Hope that helped.

is that a super dish network dish?

@TalksWithDirt 1 Joule can raise about 0.24gram by 1 deg celsius so 500 Joules/second = 120gram 1 deg celsius per second
