> It'd be awesome to save that, but it's not game changing An 8-15% increase in available electricity without any new power plants built isn't game changing?

> It'd be awesome to save that, but it's not game changing An 8-15% increase in available electricity without any new power plants built isn't game changing? The ability to transport power over longer distances, making eg. solar farms in remote locations suddenly feasible projects isn't game changing? > and you have to take into account the cost of replacing the wires No I really don't have to, as we, as a species, seem to have money in abundance. What we do not have in abundance, is biospheres. We have exactly one of those, and if it's ruined, all the money won't help. The ability to suddenly boost the efficiency of our electrical grids by 8-15% would not solely solve the problems our species currently causes for itself, but it would help a ton.

Costs are not just money. There is an environmental cost to making and installing things. Spending the same amount of money on green power generation would probably help the biosphere much more. > making eg. solar farms in remote locations suddenly feasible We can already get losses down to a couple percent per thousand kilometers. Those farms are already feasible.

That's far from clear. If our grids are 8-15% more efficient and the cost of electricity falls accordingly, it will boost demand and we may end up needing more power plants than we otherwise would have. If the goal is to reduce the consumption of a resource, making its consumption more efficient is often counterproductive (see [1,2,3]). Granted, if the alternative is burning fossil fuel then it's a good thing! But once electricity becomes more economical than fossil fuels for all uses, making it even cheaper is not going to help the biosphere. And I think that's probably going to happen before we have a room temperature superconductor that can be used in power transmission.
