Hi Bryan

That’s a great point about turning white goods into solar cookers; never thought about using microwaves (the shell of) as a solar cooker, after all they offer great efficiency and would therefore offer high rates of return on energy conversion. Just place some reflective panels on the front and you’re up and running.

If only we had sun in the UK, I would love to test this concept out… The Microsun Solar Cooker.

Rob , Spot with your comments . The GSO and it’s ilk sell 1000’s every year all over the world and the parabolics many times that I’m sure . Granted not the convenience or rapidity of a microwave and all those modern appliance but there is a great satisfaction to be gained by regulatly turning out a sun-cooked meal .

The world is changing ….it should be simple to gut useless microwaves and turn them into box cookers Toasters ? I don’t know …never had one

Hi David
Thank you for your input. With the exception of the hot pot, all the solar cookers you see in post do actually boil water. The radiant heat which is focussed on the pots for the various designs is plenty sufficient to boil water, dependent on how efficient cooker/s are with converting solar energy. Only one square metre of solar radiation hitting the Earth produces one kilowatt of energy. Once again it boils (excuse the pun) down to efficiency of design of solar cooker.

Solar cooking is all about educating people on viable and alternative energy sources, for equatorial places like Africa and Asia, there are a plethora of solar cookers in use every day. THEY REALLY DO WORK.

I have boiled water and cooked food with my solar cookers and that’s in February, in Birmingham, England, admittedly on a nice sunny day.

May I suggest you try building one yourself, you will be pleasantly surprised, food tastes great.. and it’s free energy.

Why not purchase some reflective vinyl, and line a pizza box, or cardboard box, and see the results for yourself.

Solar cookers are extremely ECO-friendly, especially for 3rd world countries not needing to gather fire wood on a daily basis.

There may come a time when we won’t be reliant on microwaves, ovens, etc, we are living in very fickle times my friend, and great changes are on the horizon. With regards to your comment ‘there is no possible way to focus all the light and energy at one single part’, may I suggest you check out parabolic solar cookers, they are the most powerful design of all solar cookers, and you can MELT METAL with them.

Please let us know more of your thoughts David.

Dude, theres no way that the sun can heat one of these pots enough to boil water straight up. It can maybe get to 250 or 300 degrees but in no way will it ever have enough heat the boil water. It would have to be at least 500 degrees or something like that to make it boil.

Secondly, although the sun is quite hot bro, it is also over 10,000 miles away, making the incumbent radiation close to nothing due to its angle of incidence.

And lastly, these will have no chance of ever selling becuase there is no need for solar power cookers/ovens when we have microwaves, ovens, and toasters in our kitchens already. And in addition, there is no possible way to focus all the light and energy at one single part bro.

Take these facts into consideration when considering designs that are so called ECO-friendly.

This really works?? This would be great for my surf trips.

Hi Marietta

Parabolic solar cookers certainly are great fun to build and use. They are the most efficient of all solar cooker designs.

Plato in his day used the parabolic design to create his very own Solar Death Ray which was used to blow ships up.

I love parabolic solar cookers, they can generate quite a lot of heat

Hi Bryan

Portability of parabolic ovens is certainly an issue, however the SolReka solar oven overcomes the issue of trying to carry around a huge dish on your back and looking like something out of Teenage Mutant Ninja turtles.

I would like to discuss matters further with you once my oven is ready for sale (link up our sites and promote solar cooking in Europe).

I very much like the idea of a Northern Hemisphere day, I conducted a solar club here in the UK only last year, the kids loved it.

I am about to post an article showing how easy it is to build a Cone Solar Oven

Regards
Sol

We’re down in Granada this weekend – starting yesterday with a spanish ecological organisation – and a whole collection of solar cookers . It’s good to see the Sun Oven is still by far the favorite because of ease to use and consistent performance . Parabolics are impressive …but portability – mmm . the little cookit is always in favor but price plays a big part …it comes with a requirement for lots and lots of patience . La Trompeta in absent still but I have some plans for August when I finished some tests .
How about August 2 – which someone has declared ‘ Northern Hemisphere Solar Cooking day . I don’t like manufactured days …’International Take Your Hamster To Work Day’ and all that ….but if it helps publicity …and with a little work …that’s good ..

Had the first day of double digit sales on Wednesday , then more Thursday ..and yesterday 2 more to a summer school who had tried various cheaper options but wanted one the teacher had usedinthe US and knew worked …

A good week .!
