Boiling water in the garden using our "Parabolic Solar Cooker"

Here's a challenge - try cooking without using any fossil fuels (gas, electric power or wood). Yep, it is actually possible by simply harnessing the energy of the sun.

This weekend, we set up a "parabolic solar cooker" and did just that. Well done team.

A solar cooker can do anything an oven or stove can do without putting any strain on the earth's precious resources (or the household electricity bill). This is quite important in countries such as Chad or Sudan, where timber supplies are rapidly dwindling and access to electricity is limited.

Parabola

The "parabolic" design of the reflector "collects" sunlight and then focuses the heat onto your cooking pot with such intensity that it boils or bakes the contents.

The drawback of cooking with sunlight is that it won't work on a very cloudy or rainy day or night, and it can take twice as long as an oven or stove.

Aside from that, it has been great fun to cook our Sunday lunch outside in the garden knowing it costs nothing at all save patience.
