One really great potential of unlimited, cheap fusion is that other things could potentially come ” riding - in ” on the back of it.
For example, not everybody wants to get their electricity from a centralized source. While a fusion reactor small enough to fit in a garage is certainly smaller than something like Three Mile Island or a large coal - fired plant, it’s still too big for an individual homeowner who wants total independence from the grid. However, photovoltaic solar panels are expensive to manufacture in large part due to the energy intensive process of extracting and refining ulta - pure quality silicon. But if focus fusion makes cheap and unlimited energy and silicon possible, then cheaper photovoltaics could then ride on the back of fusion.
Another example : Although it may never happen if the government DEA keeps up their absurd anti - hemp policy, focus fusion could assist in helping to grow more hemp for just about anything and everything in a more environmentally sound manner than is done today : food for a hungry population, building and construction materials, and renewable transportation fuels like biodiesel and butanol. This could be achieved if focus fusion can produce unlimited fresh irrigation water from the sea. Dump plenty of water on the deserts of the American Southwest and it becomes a major hemp growing region ( algae ponds, too). Dump water on the dry Australian Outback and you have a second major growing region. Pour water onto the Sahara Desert of Northern Africa and it becomes a third major industrial hemp growing region ...... so that all the poor in Africa now have plenty of food, construction materials, and renewable transportation fuels. Many other areas could produce more as well.
I could probably go on and on about all the other energy and fuel sources focus fusion could help to create. Such as hydrogen from seawater. Or even extract CO2 from the ocean to produce renewable transportation fuels like I discussed in some other post.
