In theory you can fuse up to Iron.... the last stage of stars. You are not limited to just Hydrogen.

- tapas73 5y agoI assume that some of fusions done by the star are net energy consumption (i.e. not usable for energy production)
- ncmncm 5y agoYou assume wrong. Anything beyond iron is made in a supernova, i.e. in the last moments before it is not really a star at all, anymore.
- chii 5y agotakes a star's worth of gravitational force to push atoms like those together in the core to produce fusion. To reproduce such heavier elements in fusion reactors on earth would require, likely, a much higher energy than the output.
