It’s not a scam. No one’s running up private jet bills. The science team is legit and impressive.
It’s just a teeny operation and taking an inordinately long time (for shareholders at least) to get any kind of toehold on the road to commercialization.
Their first product, the bio solar panel worked but didn’t find any kind of market. A longer lasting battery for (hopefully) not much more cost would certainly find a market. But the tech is super rarefied and we just have no indication if they will ever get there. Bit like investing in a biotech. Could be a patented gold mine or could all collapse late in phase 3.
