Not only infinitely recyclable, but like 99% recyclable right where it is located as well. You don't need to ship in a bunch of material when the process is tearing up what is there, processing and adding a little more, then putting it right back down.
Concrete done right has a far longer life span. We have a few concrete roads that just fall apart at the seams every time they are redone at certain intersections. I would bet they are either rushed to try and keep the intersection closed for as short as possible, done by the lowest bidder who didn't budget to do it right, or the intersection has such a shitty foundation/drainage that anything on top of it is going to fail.
Other roads that seem to have just as much traffic have held up fine for decades.
The primary reasons that multiple attempts have failed for over 100 years! Motors in each wheel could possibly cross the barrier of complexity, but I'm still not expecting this to make it to mass production anytime soon.
Knowing how to do it conceptually and knowing how to do it in mass produced cars is the big thing and I am expecting this to either not be cost effective. Not sure if it will be reliable for over 100k miles, but I expect the cost to limit it to the weird luxury car space at best.
You can use ground in a car to complete the circuit, such as when using jumper cables, but the frame is the ground and you aren't getting power from the frame.
Maybe you are thinking of negative and positive wire markings being the opposite?
Rode in an old steam train that has a boiler fueled by coal. Got to see the furnace that heated the boiler have some fresh coal shoveled in before we went for a short ride.
I don't remember if it is called a furnace on a train, it was a few decades ago and I'm too lazy to look it up.
Someone can intentionally trick someone onto a slippery slope and grease it up to make the slide faster, like Republicans are doing right now with undermining abortion and LBGTQ+ rights while claiming it isn't a slippery slope.
Where do you get the idea that a slippery slope must be unintentional?
Is someone slipping on a banana peel unintentional if someone drops the peel in front of them? Do you think you might be taking the word 'slippery' a little too literally?
