The Use of Hydrogen as an Energy Carrier,clear power plants took 15–20 years to reach the prototype stage, and will take another 20–30 years to make a dent in the electric market. So we have to start right now if we want to be ready with a new system in the year 2000, the converging point of many forecasts of doom, concerning particularly energy.
