Moderation Notice
Can I remind posters that in the 'Mind Zone' part of the forum the following rule applies: Avoid mocking/joking responses / images / one liners.
Thank you. I thought it was a valid point about electricity storage given that I am a professional electrical engineer - but I suppose you are the global moderator. |

It was not a specific response to your post it was a general request after deleting some irrelevant posts.

I was hearing from a nuclear fusion expert who was talking about reclaiming heat energy from fusion to generate electricity, and he was talking about the Carnot engine. He said the devices available today to do the job are very close to the Carnot efficiency. This was my view earlier in the thread as well. What he reckoned though was with current technology it is impractical to go above 1000C, explaining the pipes would melt and so if you were running at 1000C you should expect 70% efficiency. Naturally you have a trade-off here between efficiency and difficulty in constructing the machinery out of high melting point materials, like perhaps ceramic composites. Anyway, 70% is still not bad for something that we could do with off-the-shelf technology and once we have that we can perhaps crank it up in temperature as we do the research and development. You have to start somewhere. Never expect the first prototype to be as good as a technology that has been around for decades.

And what was the original post at the start of this topic and one that you have continued to fail to grasp. It is rather serious subject. |

And what was the original post at the start of this topic and one that you have continued to fail to grasp. It is rather serious subject. I suppose I could have used Energy Storage in the title, but it is what it is, and too late now. The idea was to identify it with these renewables(wind + solar) which generate electricity which we need at a later time. Yes you can store it, but then this works by converting it and then back again. I can't see why you make such a fuss. The thread was also intended to talk about batteries, which i suppose you could say they "store" electricity. |

The electrical supply is instantaneous. |

The electrical supply is instantaneous. It was a bit colloquial. I would not do it if it were a scientific paper. But being a forum I thought it suited it OK. You see energy storage could imply all manner of things like oil and gas. This thread is intended for electrical energy. I don't wish to say any more about this triviality though and think you aught to focus on which methods we should use in order to get to net zero without returning to the jungle. |

It is your topic, it is a serious subject, and now you want to make it colloquial? And I remind you that we don't use electrical energy storage. Think Dinorweg. |

It makes a 1000C heat engine at 70% look reasonable in my mind. Heat is a compact way of storing energy. Potential energy is not. We can't really scale that up too much. |

You are boring the shit out of me going over and over the same trivial point. Now back on topic. |

You are boring the shit out of me going over and over the same trivial point. Now back on topic. You know what my field is. I have have given you solid facts and have corrected some of your errors. I'm done with it. I suggest you do the same. Move on. |

Let the British technology stagnate eh? I heard the other day on the BBC the suggestion we should go back to water wheels on streams.
