Dried foods is good money wise, most of dried foods in USA is either local, South American, or Turkish/Mid-East/Central-Asia.

I buy raisins and uruk(dried apricots) my guess is both are from Turkey since the stores I get em at are Russian and simply speaking without local retailers buying your stuff in bulk and at low prices you have no shot.

I have been thinking about this:

1) bullet proof vests to SA how much are they there and who sells em? or does Denel make their own.

2) plexy glass? for bulletproof windows and motion sensors or IR sensors for area security. Ergo if someone between the weght of 100-300lbs walks over it it alerts you but otherwise not really. perhaps bear traps for people lol.

3) adrianh you might be interested in energy storage something like gyros. I mean flywheels. "Beacon power"(went bk but got bought out, so still alive) had interesting technology for flywheel energy storage. Not a new technology but hardly ever talked about. I don't think its' effective for us small users or even small commercial users.

Then you have micro trubines which is somewhat interesting like capstone, but there are diesel and gas generators by big firms like Briggs and Stratton and Yamaha I think, and little guys like Hardy Diesel generators. If their cost and operation is cheaper than Eskom+Municipal overhead charges it might make sense.

Theoretically if you spend more than 63 cents per 1kw an hour it might make sense to get a generator. Assuming diesel cost per gallon is around $7.5 and it takes .84 gallons per 1kw generated as it says in calculations. Most of these above in the states can work on Nat Gas cause we have a lot of it so for some it makes sense.

4/5th) Idea is to figure out what has some energy demands but is not economic on the grid, but is economic off the grid, get grants from own government for part of it, and exploit the niche between grid/non-grid parity. Automate it to compete on labor interruptibility etc...
[Looked at Zhauns, not it in my mind]. Small sugar processing plant might make sense if you actually produce a diesel out of it or an ethalnol aspect. Ergo make it for yourself in essence and distribute to gas station. Granted all of this is already in the multi-million dollar world.

Perhaps fertilizer, or coffee roasting and packaging.
