yeah why it is not feasible is because the heavy water tritium and deuterium needs a gargantuan temperature of about 15 million degree celcius that which is been provided in the sun and stars. It is also feasible in the sense that this high temp can be provided through fission e.g pitheblend, but this reaction would not be controllable and so can cause massive destructure

you can start with c++ or C#.You should also download devc++.
when you get to an average coder's mode, you should download eclipse.

when did y'all start coding?
//what age did you start coding?

you do not have to be a math guru but at least have a deep insight about mathematics.being a guru is another thing on its own and does not necessarily promote deep understanding about programing.In the real sense when starting to program, maybe c++ it appears absurd especially the maths side of it.
