Yeah this is a big problem with fusion too, it requires a really big concrete footprint which limits how cheap the power can be.

- anonuser123456 4y agoToo much concrete is probably the smallest of fusions problems. The tritium fuel cycle is pretty much impossible to solve economically. We already know hydrogen infrastructure isn’t very cost effective. So imagine radioactive hydrogen.
- pfdietz 4y agoThis is one reason (among many) to prefer Helion. It doesn't use DT, so it doesn't have the problem of closing a tritium cycle. It won't even have a lithium blanket. Tritium does get produced from DD reactions, but it can be just separated from D, stored in metal hydride beds, and allowed to decay to 3He.
- loeg 4y agoThe other major problem with fusion being, it hasn't successfully produced energy (on Earth).
