I would look into making a still for distillation of water,alcohol for drinkin'& alcohol for burnin'!What is the main fuel of Africa? Charcoal,yes sir,It lasts a good longtime,is multi-purpose & Cheap to make whilst warming the bones,& Is a very necessary commodity!Maybe get some sheep,Wool is the best for staying warm when away from the homefire!A variety of sizes of cast-iron ware,including a cauldron for stewing.A hand crank mill for grains would be an Xlnt investment,as would stainless steel containers for storage.You could build yourself a forge for melting scrap metal,& self-learn some Blacksmithing,during hardtimes that would be an Xlnt position,indeed!Or......Move in with the colonials,We will keep the light on for you! Cheers!
