But not all scientists are convinced that helium-3 is the proper solution for the planet's energy needs. While helium-3 has potential, no one has built a fusion reactor that can economically extract its energy yet, and it may take decades to do so. Other experts aren't convinced it will ever be economically feasible to produce massive amounts of energy from helium-3. Still, helium-3 has scientists--and entrepreneurs, no doubt--interested.
