As long as the voltage is high enough the amperage can be made entirely bearable. 10MW (about 14000 hp) can be moved with just 100 amps at 100kv. Most houses

As long as the voltage is high enough the amperage can be made entirely bearable.
10MW (about 14000 hp) can be moved with just 100 amps at 100kv. Most houses have something like 100 amp service from the power company. At 1000kv that's only 10 amps. 10MW for 10 min is about 1500kwh or enough to charge some 15 teslas approx to full.
The power levels you're talking about are big compared to household stuff, but kind of a joke compared to industrial processes.
- eMGm4D0zgUAVXc7 6y ago> 100kv [...] 1000kv Don't those voltages leak like crazy across things which a normal person would consider as a safe insulator? E.g. might some regular dirt on a plastic charging cable leak it into your hands?
- XorNot 6y agoIf you're considering those sort of voltages you might as well look into just using liquid nitrogen cooled cables and super-conducting cables. Liquid nitrogen can be made from the air on-site if needed, and is a hell of a lot easier to handle then hundreds or thousands of volts.
- meowster 6y agoI've never heard of "leaking", but higher voltages are more likely to cause arc blasts. Usually that only happens when a switch is thrown.
- SulfurHexaFluri 6y agoIs it possible to make a cable safe enough for people to be holding at 100kv?
- jazzyjackson 6y agoWhy copy the UX of a gas pump, maybe we can go back to the luxury of staying in your car while the pump is operated by an employee/robot -- pop the charge port open and the "pump" steers itself and locks in.
- tsomctl 6y agoThought I saw a Jalopnik article about Bentley or Rolls Royce inventing that exact thing, but I can't find it now. The idea being, if you're a billionaire, you don't want to do something low class like plugging in your car.
- 6nf 6y agoYou can't have a 10kV or 100kV charging station being handled by the general public to charge their cars! That kind of voltage needs specialised equipment and is extremely dangerous. There's no such thing as a consumer grade 11KV insulated cable.
- 01100011 6y agoIt doesn't necessarily have to be a cable. It could be rigid. You could even have a platform which moves the car up to the charger. I could see some sort of telescoping arm made of teflon though.
- akvadrako 6y agoDo you think these 100kv cables are unusable? https://www.schleich.com/en/product/high-voltage-cables-en/ https://www.schleich.com/en/product/high-voltage-cables-en/ I mean you would need some smarts to ensure the leads are never exposed when active but otherwise I don't see the issue.
