Toward a sustainable future

Exploring simple devices that may help us conserve, get off grid, and perhaps save some resources for our kids’ kids.

The more complex a system, the more ways there are for it to break. We have not experienced cascading systems failure. Yet.

Solar cooking is a fast easy and inexpensive way to get off grid and lessen our dependence on fossil fuels. You can buy very good commercial solar box ovens for a couple hundred dollars and with care they will last you many years. You can also make your own for very little money and can use materials for the reflector ranging from cheap aluminum foil to very nice shiny mylar to long-lasting glass mirrors. I prefer mirrors because they have excellent reflectivity and are long lasting as long as you don’t break them.
