Nuclear fusion reactors

Nuclear fusion reactors are a term used to describe a future source of energy. Most stars including our own Sun released energy by nuclear reactions between light atoms at temperatures of millions of degrees. This process is known as thermonuclear fusion, at very high temperatures cause light nuclei to fuse to produce heavier nuclei such as in the centre of stars. Inside the centre, four hydrogen atoms (atomic number 1) react to produce one atom helium (atomic number 2), in a nuclear fusion process, the weight of the hydrogen consumed is more than the weight of the helium atoms produced.
The mass difference converted to energy 0.711% of the mass of hydrogen atoms is energy.

Less than 1% does not seem like a large percentage, nevertheless the energy equivalent of matter given by Einstein’s E = mcˆ2 is extremely large. The conversion of one gram of hydrogen (around 1 to five of a small coin) to helium produces as much energy as the combustion of 17800 litres oil (112 barrels).

The energy of one gram hydrogen in a nuclear fusion reaction = 17.800 litres of oil (112 barrels)
