As referenced, it is tough to do experiments that require a lot of energy when you do not have it to use. Once that happens, technological advancements could come about in a major way. For example, a specific vehicle could run on nuclear fusion entirely. It’s hard to know without testing, but if that could occur then one would never need to pay for gas or oil and never need to charge it. On top of this, that car could likely reach extreme levels of speed. It is possible this would go to the military before consumers ever see it. Technological advancements often need a good budget, and the U.S. Military has a huge budget to dedicate to stuff like this. Primarily, energy needs and supplies are the bulk of the cost. With nuclear fusion, more of us could work on big stuff like this at any time.
