is constantly present in our solar system. In the core of the sun, Hydrogen is converted to Helium providing enough energy to sustain life on earth. This process occurs at temperatures of 10-15 million degrees Celsius. We are now trying different methods here on ....

.... the problems is attaining the correct temperature for fusion to take place without using more energy then you produce. Fusion reactions occur at a sufficient rate only at very high temperatures. Over 100 million degrees Celsius is needed for the Deuterium-Tritium reaction, while other reactions require even higher temperatures. (Hotta Labs, Source 1) The density of fuel ions must be sufficiently large for fusion reactions to take place at the required rate. The fusion power generated is reduced if the fuel is diluted by impurity atoms released from surrounding material surfaces or by the accumulation of Helium "ash" from the fusion reaction. As fuel ....
