You had four million dollars? In 3 years they suspect gas to hit 8-10 dollars a gallon. You are filthy rich and have the means of stock piling the one million gallons. In three years if economists are correct gas will hit 10 dollars a gallon. You can then make a deal with a gas company like Hess or whatever to sell the gas through them at 8 dollars a gallon. Hess will do it because it will put a huge boost back in their in store sales and even if they dont you can find a way to sell it somewhere anyhow cause people will be rioting for it.
100% return of your investment. Would you risk your 4 mill to make 4 more in 3 years?
