I live in Guernsey and it is pretty damp here the whole time. Alot of the houses are old granite ones and the traditional approach was to have an Aga running to keep the perceived moisture levels down. I grew up with them and love them...

However, I guess that they are the car equivalent of a 4x4, guzzling oil like nobodies business.

My gran has an electric one (Economy 10 or something) which is a more indirect way of using fossil fuels (no direct personal combustion), but still pretty bad for the environment. I think that the local electric company is looking at a tidal solution but that will be a while away.

Anyway, it got me thinking. My gran's Aga is much like a very large night storage heater - a bunch of bricks that heat up and store energy and then release it for cooking.

Surely there must be a way to heat up that amount of bricks (or whatever the material inside is) to the correct temperature by solar energy? Would PV panels work or would you need to use some kind of evacuated tube/water solution?

As you can see I am blissfully unaware of all the details but hoping to find out alot more about solar power in general (will post another thread on that). So if you are more practical in this area please let me know if this exists or is possible or even is desirable.

Cheers

A mate of mine makes solar cooker things for Africa/third world places. He took some large sheets of stainless off me in the summer and had a good chat about tracking ... He found some multi use encapsulated circuit units that can be programmed and plugged into external feeds (like thermometers and light sensors) - he has had some good results with tracking mirrors apparently. I'll have another chat with him...

From http://www.everhot.co.uk/faqs_general.php

>> How much power does an Everhot use on average?
>> When set at our recommended cooking temperatures our 2 oven cookers will consume around 88 units of power per week.

88kWh/(24*7)h = 524W

That is a lot of power. And they claim their cooker is more efficient than an Aga, which I can well believe.

If you want to go "eco", maybe you could get a woodburning cooker from Esse? That uses solar power; it's just very inefficient solar power!]]>
