A huge amount of energy is wasted distributing electricity for 10s of thousands km.
I am not sure how it can help storage though, even if you theoretically can let the electricity spin in a closed loop forever the energy density seems way too low to me.
- gingabriska 8y agoGraphene based supercapacitors have huge capacitance because graphene is single atom thick, so you can put a lot of layer of this material increasing total surface area hence capacitance for same volume of capacitor space used.

- gingabriska 8y agoI've same problem, it's now less bad with Quick Charge and Powerbank combo but still bad.
- fsh 8y agoA standard 380 kV power line has a loss on the order of 1% per 100 km. Unless you want to span large continents, this doesn't seem like a big limitation at all.
- tigershark 8y agoPower Lines are several hundreds of km and even only 1% of the global electric production seems a huge amount to me... But in reality it is much more, in US is 5%: https://www.eia.gov/tools/faqs/faq.php?id=105&t=3 https://www.eia.gov/tools/faqs/faq.php?id=105&t=3
- fsh 8y agoThese numbers show that the grid is already 95% efficient! It makes much more sense to improve the really inefficient parts, such as power plants and electricity consumers.
