Are we doing it right ? (Just Kidding...but can be Future !!)

 When we first understood about fuels we always heard about ignition temperature or something sort of activation energy, which helps us to release energy from it. But is the fact true for all kind of  fuels,,, we have heard about nuclear fission and we extensively use it for powering various things...but when we talk about nuclear fusion we are told it is a developing concept and for this we need huge amount of energy and temperature to start reaction.. But according to me the better way to generate nuclear energy is by lowering the energy levels so low that it will compress the atoms extensively leading to extremely strong inter nuclear repulsion which would suddenly push the atoms back apart to re instate equilibrium.

This sudden release of energy would be discharged just before the complete nuclear fusion and from this we can generate alternate energy bands of  {high energy- low energy-high energy - low energy..} 

So if I am theoretically correct we could harness this kind of energy pattern in something very useful and without actually taking out nuclear reaction but just by tending it to do so.

Summing up I should say that this kind of energy is totally obsolete as per technology we are currently having but this could be extremely useful in outer space explorations where temperatures are considerably low to carry out this cycle and generate work...but here the only twist is that the work invested in bringing atoms close should be considerably less than energy produced by them due to strong inter nuclear repulsion.
