Northrup Grumman close to having portable Fusion Reactor

We speed everything up so dramatically in the modern world that the age of oil is probably behind us. Northrop Grumman put out that press release saying it is this close to having a portable fusion reactor. If you can have fusion nuclear energy, it’s free. You use water; the energy is free.

And unlike fission, where you need uranium, and you have dirty stuff to get rid of later, fusion is absolutely the opposite. It uses water and there's no byproduct. Power becomes free.

So not only is solar power going to be cheaper than Oil by 2026 but likely we will also have portable fusion energy as well.

However, fusion is literally the same thing as the sun. So, how do you protect people from the small sun you have created in order to create fusion power?
