Electric vehicles during a disaster

[4570Man]

Personally, I expect batteries, and motors to evolve fairly quickly in the next decade or two, as the current innovation rate is high and the translation time for technology to go from research is pretty short, e.g. a decade. (It isn't software!)

Electric motors are already in the mid to upper 90 percent efficiency range. There’s not much room for improvement there. Lithium batteries have been around for a long time. They’re not the infancy technology they’re claimed to be. And they’re also in the high 90 percentage efficient. Unless someone discovers a new element to build drastically better batteries electric vehicle aren’t going much farther then they are now. Electric vehicles might be somewhat of a success but abandoning combustion engines is a completely delusional idea.

For fun I used google maps and asked to go from Svartnes on the NE coast to Oslo, down at the southern tip.

It said it’s a 24 hour drive.

Norway is a lot like Alaska. If you want to drive there, don't count on using a road.

Had you watched more than 30 seconds of it, you would have seen it.

30 seconds was plenty for me.

Yep. Someone said to expect EVs to handle corrosion no differently than ICE cars. That is very concerning considering the oil pans, structural members, corroded circuit boards and wiring, metal lines (gas, brake, coolant, trans oil) etc. that have all needed to be repaired or replaced due to corrosion on our vehicles here in SE Michigan......

Tell me about it...lol I live in SE Michigan as well (near the Indiana line). First thing I do with any vehicle I purchase is, I pull all the connectors apart and put dielectric grease in each of them. Putting new brake lines on my wife's van right now. The steel ones corroded off. Even the muffler lasted longer but it is wheezing so that is next.

For those of you interested, here is what home battery support of the grid can look like;

Tesla's virtual power plant had its first event helping the grid – looks like the future

Tesla’s virtual power plant in California had its first emergency response event helping the grid by pooling power from Powerwall owners around the state. The event appears to have been a success as the distributed power plant looks like the future. A virtual power plant (VPP) consists of...

electrek.co

It used just under 2,400 homes to provide about 1% of California's load during a heat wave induced high power time.

With improvements in bidirectional charging that are being deployed, I would expect to see more of these sorts of programs, with much higher levels of stored energy involved. A typical home backup battery is a small fraction (e.g. a quarter) of a Nissan Leaf battery, which is a small car, with a small range.

All the best,

Peter

Hard to believe all this Lithium mining and battery production is good for the earth.

It’s fine as long as it’s done in a 3rd world country. Same story for oil drilling and pipelines.

Just drove the entire length of PA and continued west to Columbus, OH to see my daughter play at Ohio State.
Just “going with traffic” we were doing 90-95 like it was nothing.
Going 75 was slowing traffic down and felt like 45.

And those people ***** about the price of gas.

Current fusion tech. see what i did there?
Probably not in the next 35-50 years.

ITER non-tokamak design, expected to reach Q=10, needs to be at least 30 to be a viable energy source. Containment vessel, which is very large, will be bombarded by neutrons, making it brittle and highly radioactive.

SPARC a tokamak design with newer materials, is scheduled to come online in 2025. Smaller containment vessel. Should reach similar Q as ITER.

National Ignition Facility:
array of laser beams converging on fuel pellet. Would need to reach Q value of at least 100 to be a viable energy source.

TAE Technologies:
A design to fuse hydrogen with boron-11 by colliding plasma “smoke rings” inside a long, cigar-shaped chamber. This setup would need to hit temperatures even higher than those in tokamaks. The upside is that it could generate electricty without the neutron problems the other designs need to deal with.

LoL...nice paste job...!

Like I said about all the present (viable) alternative power sources...they are using "CURRENT TECHNOLOGY"...!

Instead of wasting monies on developing battery technology that rely on the grid to recharge is exactly that...a waste...!

I can't wait until the first new development that actually makes a difference in a major technology that is created by AI... it's coming
