I have a solar cooker (Mr. Sun) which I'll be writing a review on and hopefully getting ideas on. Also homemade solar oven and cooking with a solar sunshade. I've done all of them in Canada with very low cost. The solar oven was able to bake a cake and cost about N4000 to make. Cooking with the sunshade I was able to cook beans for a cost of about N2000. Neither was very elegant because my design skill is terrible but still.....affordable and at least an interesting talking point.
.... but more on that later.
First up will be 1) Clean drinking water and 2) A cheap balanced(ish) diet.
But I'm on vacation with my Mom so posts will be a little slow in coming.
That is quite cheap and will be highly beneficial here since we have abundance of sunlight.
The major points have been highlighted, lets work with that.
Enjoy your vacation.
