Idiot habshi speaks without knowledge again.
Microwave ovens actually take a lot of energy to heat food.
Your typical consumer microwave oven is about 50% efficient, which means
your 700 watts of cooking energy takes about 1.4 kilowatts of electricity
to generate.
Microwave ovens also require AC, not DC as the power source.
Microwave oven, lets say $50.
Solar panel, $50 to $100.
Heavy duty battery capable of about 120 Amps for extended periods, about $50
to $100.
2 kW DC/AC inverter, about $300.
Total: $450 to $600.
Probability of ignorant villager keeping the system running for more than
a week or two, about zero.
5 gal propane tank, full, from Home Depot, $15.
Two burner camp stove, $25.
Idiot.
