It has been known that diabetics taking Metformin experience lower cancer rates, and now it is apparent why that may be and how it may apply to non-diabetics as well. When combined with Doxorubicin to kill non-stem cancer cells, the results are nothing short of astonishing: total remission in a mouse xenograft model. The results are achieved at levels below the dosage needed for diabetic control, opening many new avenues in cancer treatment and prevention."

$659,000,000 to generate 400,000,000 watts of power, or 400,000 kW. That's a constant income of $40,000 at $0.10 per kWh. Divide $659 million by $40K and it's 16,475 hours. Divide that by 24 and it's 686 days. Divide that by 365.25 and it's 1.9 years.
