Flammable ice Its reserves are several hundred times more than the total reserves of coal. natural gas and petroleum. So it can save sources to a much degree. The transportation of this kind of energy is convenient. It can reduce the environmental pollution, The pressure should be moderate. And it can be produced under the pressure of 30 atmospheres when it is zero. The temperature should not be too high ,Its better to control it between zero to ten centigrade. There has g
