Experiments Not Possible Before Will Now Be Possible
You might not realize it, but there are MANY experiments that scientists would love to conduct but it is simply impossible given our current energy grid. This might be due to the lack of energy possible or that scientists would use up so much that it would require shutting down several cities. It might also be that if they try to use the energy they need, they could blow through energy grids. It is impossible to know exactly what would happen without knowing the experiment. Yet if it needs a lot of energy, you can bet that scientists know that and cannot do anything about it. With nuclear fusion helping to provide near-limitless energy, the sky is the limit!
