"Coldfusion" energy?

What possibilities exist for investing in "cold fusion" energy?

Answer:
Since there isn't a whole lot of evidence that it exists yet, any investment in it would be extremely risky. Even if scientists working on it do come up with something, investing in it now would be like investing in computers back in the 1870s. You will probably be dead before a penny is made on it.

That being said -- I'm sure someone would be happy to take your money as an investment.
hundreds of billions have been poured into fusion--hot and cold--with no prospect yet in sight of having a working solution. It will require hundreds of billions more at least.
That is the holy grail of power generation with the promise of unlimited and cheap energy for all to use. However the physical limitations of actually achieving and controlling cold fusion are too many and solving it is several years away.
