I was reading a small article and it was speaking about Helium 3, the benifits of it for energy seem well worth the trip to the moon. Why are we not doing this? Any imput on or someone fimiliar with h3 please comment. Thanks.

Even though I'm not overly familiar with H3, I'll take a shot. The reason we're not going there is because, at present time, the costs are simply too high to motivate it. While there might be an abundance of H3 there, the cost of transporting everything needed there (tools, machines, a base perhaps), mining it, and then getting it back down here isn't worth it.

Also, Helium 3 is good for fusion power plants, but they don't actually have one that can currently produce more power than it consumes (but they are real close - so close it is possible that they have done it now but I haven't heard yet).

point of note, helium three is He-3

 

H-3 is Hydrogen-3 (also known as tritium).

 

these are very different materials.
