WEST LAFAYETTE, Ind. — For the first time in the U.S., a roadway has wirelessly charged an electric heavy-duty truck driving at highway speeds, demonstrating key technology that could help lower the…
Research in Indiana lays groundwork for highways that recharge EVs of all sizes across the nation
I think if it’s like <= 10%, it’s fine. If we’re talking about 50%, this is beyond unacceptable.
This article claims 90% efficiency has been achieved for moving vehicles, but it should likely be taken with some grains of salt. On the other hand, with phones it’s unimportant on the level of the individual using it, so perhaps the phone wireless chargers aren’t particularly optimized and it’s possible to do better?
Or you know; trains for long haul freight…
Lovely idea and I’m very much in support of trains, but in a lot of countries the railroad infra just isn’t there and can’t be built on all routes. In my country, the 2nd, 4th and 6th largest cities by population likely can’t be connected by rail. It’d be a popular route for passengers for sure, and likely useful for cargo too given that I’ve for sure seen plenty of trucks driving between those cities, but there’s TWO large areas of wetlands in between. Super simple on a map, just draw a line east to west pretty much, but just isn’t happening in real life. Easiest way to take a train is to go through the capital. So 4-5 hours by train vs 1-2.5 hours of driving depending on what route you’re doing (actually one of the train routes to the capital is closed too right now, for a number of years already, but it’ll be replaced by Rail Baltica eventually at least so that’s nice). And that’s despite the trains being faster than cars (speaking passenger cars and trains here - I wouldn’t know about cargo)
It’s not a super long route end to end, but you could save on weight of batteries, which in turns increases maximum weight of cargo, since the total weight is limited. And charging would be a pain for long haul truckers in Europe because of the regulations on driving hours. E.g if because of a charge, your allowed 9 hours of daily driving time ends at midnight, well now you can’t start driving again before 9 AM and that’s if you haven’t used up your weekly allowance of 3 9+3 hour split rests yet - otherwise you’d have to wait 11 hours. I’ve heard tales of long haul truckers in Europe skipping their piss breaks just so they could make it to a good rest station in time instead of having to stop at a random roadside parking lot. The system sucks in some ways and truckers hate it, but it prevents their employers from coercing them into driving dangerous hours (and “hero” truckers can’t willingly do it either).
long haul truckers in Europe skipping their piss breaks
Pretty sure every trucker worldwide uses piss bottles/jugs. I’m not even a trucker, I just drive long distances to and from work (5-12 hours) and I do it sometimes.
Do we know yet what the energy loss is?

way of the road, way she goes boys
You’d still have to stop so what’s the difference?
It would be illegal to pee while driving round these parts I’m pretty sure. Distracted driving and all that
Nobody is stopping while using piss jugs.
