I now live in a place with lots of sunlight (and lots of rain) and would like to use a solar cooker. I have seen a number of designs for solar cookers (Wikipedia has a list), but I am wondering about which design to adopt.
Priorities for me are
We have a conventional (gas) stove, which we can use at will. Using the solar cooker can be a little more tedious, but boiling water should not be a one-day project.
With children around, saving a bit of energy is nice, but not if there is a high risk of going blind. I have seen an experimental design with a satellite dish, where the experimenter ended up with a second degree burn.
- (sustainable) DIY design
Preferably something rain-resistant (i.e. maybe not cardboard and aluminium foil) that can be built from materials available in non-specialist stores, which gives back the energy (and money) spent on materials in a reasonable time-frame.
