"Battery Station" vs. "Gas Station" should've been a no brainer from day one.
Next best plan should be "electric roads" that are powered by green tech.
Of course it all would be massively expensive. Sadly, it's clear that the powers that be to protect Earth's climate do not give a shit.
Highways could totally have power lines overhead...the problem is just finding the best way of getting it to the car safely (I don't like the trolley-style solution).
Not sure what the "trolley style" is.
My exposure to electric roads are electro-magnetic rails under the road that provide a constant electric field that cars drive over.
Honestly, I think it may be possible to build entire roads with enough crushed metal elements in the asphalt/concrete and a slight low power charge throughout the entire surface would be able to keep any vehicle battery at a steady charge.
But, I'm not a scientist/engineer/electrical specialist, etc ...
You might be underestimating how much power a car consumes while driving. For example, a Tesla model 3 has an efficiency of about 130 Wh/km in mild weather at highway speeds. Assuming that on the highway you'll travel 100 km/h, that means you'll use 130*100 = 13.000 Wh/h, a constant power draw of 13kW. That's enough to power perhaps 8-12 houses on average.
A km of road could have, let's say, 200 cars on it (4 lanes, 20m per car). That means you'd need to pump about 2.6 megawatts of power into every kilometer of road to keep them all topped up.
EDIT: fucked up math
And that doesn't seem to take into account transmission losses. Even the best wireless phone chargers are maybe 70% efficient. This may hit 40% if you're lucky. So double that figure.
Does using a period in your number not cause confusion? 13.000 vs 13,000. I first read it is 13 since the zeros mean nothing following a period where im from. No shade, just curious.
Apologies. I'm from a country where the meaning of the period and comma is reversed compared to the US, so I did it this way out of habit.
No need to apologize. I didn’t know they were reversed. Do yall do periods for three digits? 1.000.000,00?
Yup, just like that
Trolly style = hooking on to an over-road power line.
Yes, I should've known. It was a popular thing in my area with a bus line that stopped just within the past 3 years.
