Fusion is more likely than (radically) better batteries. I spent a lot of time looking into this. Lithium air could just about see an electric transatlantic aircraft but its at least 25 years away, The way forward is to ditch renewables and build fission reactors, and then use synthetic fuels and what's left of fossil as a stop gap. Naturally, since it's the correct thing to do, it won't happen. -- "First, find out who are the people you can not criticise. They are your oppressors." - George Orwell |

The thing is, every since the very beginning of electricity being used,
people have tried to store it efficiently. It has not been possible to increase this efficiency. I mean a two lake system and a pump is not very portable, and most of the other ways to produce it also use one form of energy to make electricity, and one assumes if everyone switched off, the generators would still have to run due to the inherent losses. It really will take a lot longer to crack the problem, and as one knows from hydrogen storage the greater the density the more dangerous the fuel. Just fire a nail gun into a modern laptop battery and see what happens. Not something to do while standing by it or indoors. Brian -- This newsgroup posting comes to you directly from...

When someone presents a graphic like the one here, you'd need to study their sums very carefully for mistakes. The article itself mentions potential sources of error or what metrics might be best. https://en.wikipedia.org/wiki/Cost_o...city_by_source "Note: Some caution must be taken when using formulas for the levelized cost, as they often embody unseen assumptions, neglect effects like taxes, and may be specified in real or nominal levelized cost. For example, other versions of the above formula do not discount the electricity stream." But I've been seeing articles on Arstechnica for the last couple of years, where it's been mentioned that wind farm developers have been offering very attractive contracts for power. It's just possible that the graphic in that article, declaring wind a winner, isn't far off. But since those graphs are also used to "sell things", we can't really trust them all that much. Paul |

Fusion is more likely than (radically) better batteries. Could you not run a Tesla or airplane off beta voltaic batteries. It might bump the price of a bit..., but in principle it could work, couldn't it? |
