Doubt the power of the sun?

This was a quick vid taken on Sunday August 17/08 to demonstrate just how hot a parabolic cooker is. Take a look.

Hi, I am planning to make a solar oven and gluing aluminum foil to the sides of a box....do you know if the glue gets too hot from the cooking if it will cause toxic gas to contaminate the food? is there a certain type of glue i should use?

@HandsomeSasquatch - The outside flaps don't get warm at all, so any glue will work. For inside, Elmer's "Glue-All" white glue is what I use for all of these items and never has been a problem. If you are making a box cooker, check out my 60/30 solar oven videos - I offer free plans for these if you send me your email to mamodbasher(at)gmail(dot)com. Thanks for watching! Ken.

Where did you get the dish from?

[hipofalcon]

@SolarizeYourLife - the dish is a Chinese unit from a company formerly known as Sangli. They are still available, but only if you want to buy them in quantities of at least 10. There may be a fellow in the U.S. somewhere that still sells them. Ken.

Nice job Ken

The demo should certainly put a stop to people feeling the need to put their hand in the middle to test how hot the cooker gets.

What's the outside temp, and what temperatures have you obtained?

@riv2012 - the outside temps at the time were quite warm - likely about 27C (maybe 85F) - I can't really say what temps the dish gets to, but it boils water very quickly. A litre of cold water will be boiling in about 8 minutes. Ken.

@SolarizeYourLife Thank you Sir, best of luck.

@manhoosnick As long is there is more than 50% sun than clouds, you can use it any time.

@SolarizeYourLife

Couldn't you just buy a 36" satellite dish and put aluminum foil or mylar on it?

[manhoosnick]

Thanks for sharing your stuff Ken :) , I was wondering if it can work with winter sun too? like 5-10 C, I am in France

@petercawaing Sure is using fiber optics.

@cdltpx I was not sucessful using the microwave I got it to run a 700 watt microwave on a 1Kw inverter and saw I would require 2x more battery and solar panels I was not about to get into all that just to heat a meal. It would be like building a robot to flush the toilet why just hit the handle. Its possivle but not wise. Maybe with a generator but again if you are going to burn gas use the stove.

Did you know there is another way you can cook keep warm etc? You can produce your own methane at home I located two ways on YT one uses cow dung the other uses table scraps either way I would call it RE since you are using methane that is being produced anyway you are just collecting & burning it. Byproduct useable ferterlizer for your garden. Look in my favorites one is on the top bar the other is in there somewhere. I tried to use solarpanels and microwave not good idea too exspensive.
