Battery based electric vehicles of today and tomorrow.

i'm pretty sure the buried wires in factories are for guidance etc for their smart lift trucks etc etc.....vs power. maybe that's what you meant.

i went into a huge warehouse customer visit for something, don't remember but....i do remember it was almost pitch black and you could hear these robots running all over the place. they snapped on the lights and i was blown away by how big the place was....and dark, and all the robots.

yes, you are probably right!

for a long time texas legislation, influenced by american airlines, had some strange rule regarding SW Airlines departures and landings.

been a long time and don't remember the details but, another example of legislators being bought and sold by special interest.

That was actually Federal regulation.

A Tesla, SpaceX & Boring Co Theme Park? Yes, Please

A thought that never crossed my mind.

I could see how this could be something a father of 6 young boys might do.

From a note left on a Tesla I expect in the USA today's 13 year olds will become key to the EV market place. 10 years from now EVS will either be commonplace or not exist on any major scale.

Heck,

I'd even go to look at pallets in fields

Living on the water I have always wondered why this type of power generation is not more developed. Tidal flow is as predictable as can be.

The 'world's most powerful tidal turbine' starts to export power to the grid

The O2 turbine weighs 680 metric tons and has a length of 74 meters.

That's another century old idea, which modern technology is trying to make more practical.

What's the ROI on that?

"ALL?" The only implementation of wireless charging I have ever heard of is the Shanghai busses with fast solid state capacitors and charging stations installed under the pavement at bus stops.

Search term, "smart road". It was the big wet dream before Elon Musk kicked the Toyota Prius off the podium.

This one used simple electrified rails, World's first electrified road for charging vehicles opens in Sweden

Others fantasized about contactless charging in motion without realizing they were building a linear motor/generator. That the force to pull the EV over the embedded coils in the road would be greater than the electric power transferred.

Coil only needs to come on while the vehicle is in position.

Pay attention, I am talking road not parking space.

High power wireless (stationary) charging adds a lot of weight to the vehicle and is much less efficient than a simple umbilical charging cable. Is impractical fantasy.

Lets say you manage to transfer 90% of the energy to the EV BCM for use in charging the battery? 240V @ 40A on a 50A circuit is 9600W. You will be dumping 960W of heat into your garage. About same as most portable electric space heaters. This is over and above the losses in the EV to convert that power into chemical power in the battery.

Video is for the TV generation who has to be spoon fed by "marketing people". If they had a serious presentation then it will be printed so that their claims will be accurately recorded.
