If energy density were proportional to cost, nuclear fission would already be dominating by a factor of 2,000,000x over fracked gas and coal. The reality is that complexities of systems needed in energy conversions end up coming into play. Getting net energy out of fusion was done in the 1950s (explosively, but still). Even given sustained controlled fusion, you still have to build a power plant around it and 'break even' on costs.
- pfdietz 6y agoRight. The energy density argument is obviously wrong, and I marvel that people can still make it with a straight face.
- Hasz 6y agoThe comment is mostly about energy scales -- Getting into the actual conversion rate, system efficiency, amortization etc is beyond the scope of a comment, especially when it's still an area of very active research.
