quote: So here's our problem. Even if you manage to create some supercondutor hyper technology that's capable of delivering 306 million joules of electricity in just 1 second, you need to generate 306 million joules of energy in 1 second.
quote: And that's completly ignoring the issue of heat transfer and the fact not just the charging equipment but the powerlines from the powerplant all the way to the charging equipment have to be able to handle that many joules of electricity each second. Not just a second, they have to be constantly fed with electricity.
quote: let's say the average nuclear powerplant has an output of 1000 megawatt/hour, or 1 million kilowatt/hour, or 3,6 trillion joules in an hour. Hour has 3600 seconds, so 1 billion joules each second.
quote: Now, all the electricity we use is also generated right now, we have no form of long term mass storage of energy. Meaning shut off all powerplants in the US, the entire US goes dark.
quote: There is something called pumped hyrdo power. We (the US) have the ability to store around 5% of power for reuse later (we only get 4% back, so its a net loss in power
quote: Pumped Hydro generation capacity is not the same as storage capacity, and the latter is the important metric for making wind/solar usable.
