Its a lot easier than you think. Just like trains, but on roads. The highway where trucks work like electric trains: https://www.youtube.com/watch?v=_3P_S7pL7Y

The highway where trucks work like electric trains: https://www.youtube.com/watch?v=_3P_S7pL7Yg https://www.youtube.com/watch?v=_3P_S7pL7Yg And, there is electrification happening along highways, producing energy. German highway PV could generate up to 200 TWh a year: https://www.pv-magazine.com/2023/04/11/german-highway-pv-could-generate-up-to-200-twh-a-year/ https://www.pv-magazine.com/2023/04/11/german-highway-pv-cou... Also, battery swapping will become a thing. You don't have to haul a ton of batteries, you can swap them in seconds along your route. There will be (eventually) a ton of battery plants replacing peaker natural gas plants, these will be built along the highways, also serving a second function of battery swap stations.

Electrified highways is a super interesting idea. In this video they're hybrids though - presumably they come up to speed with combustion and then just use the grid for cruising. And I don't think it's a huge cost to have a gas and electric motor anyways, it's certainly not as heavy as a 1000KWH battery.

This is about large battery powered EVs, not grid powered ones. Also, it doesnt matter if you can swap a battery, or charge a fixed one in a microsecond. the problem is the opportunity cost of using a lot of battery to electrify one vehicle instead of hybridizing many more EVs by taking away batteries from hybrids are bad.

  Thanks for the explanation. Curious if there are any truck manufacturers making hybrids? Is there a Prius equivalent of trucks?

    I knew one guy who was working for a company that did that. Bit it's not an ideal use of batteries. Semis avoid cities, they avoid stop and go. Long cruises negate the hybrid advantage. Where hybrids shine are in heavy vehicles that do a lot of stop and go -> urban delivery trucks and contractor vehicles. This is where all out effort of electrification should start with, hybridizing these vehicles. Also, if you're serious about CO2 emissions, the most effective way to decrease them is to enforce lowered speed limits.
