Re: The Switch To Electric Vehicles.....


On the 'leaps in technology' issue, there was a dude on Coast to Coast last night who was discussing the re-invigoration of the space program since it's been privatized. I guess Elon Musk's company SpaceX has just tested a super large rocket?

This man was claiming that things are moving so rapidly that it will be practical to have manned moon bases in about 5 years. When the lady interviewer asked him why anyone would want to have a manned presence there he had some really interesting reasons.

Among them were with no air there is no distortion and with modern camera and software technology one could do lens arrays that would be the equivalent of a kilometer in width which he said would be large enough to see activity on planets around other stars.

He also was touting moon tourism as the price of getting into space plummets. He was saying that with the gravity being 1/6th that of earth one could strap on wings and fly inside the large glass domes that would be the Hiltons of the moon.

What was germane to this thread in his conversation was his statement that Helium 3 is apparently abundant on the moon and is the preferred fuel for fusion reactors which he thinks are going to be coming on line in the next 10-20 years. He was saying that up to now there hasn't been as large an emphasis on fusion technology because Helium 3 is so rare on earth. With an established moon presence it will be the Helium 3 rush on the moon he claimed.

Re: The Switch To Electric Vehicles.....


Fusion is pretty interesting, it has been a struggle to get break even or better.

I considered trying a different approach that would be pretty interesting, but in the end, I don't have that much interest on the technical side, more of a " I wonder how close I could get doing it this way".

Optical "seeing" is really limited on the earth, which is why Hubble was put in orbit. We do have array telescopes on earth, but they still have to pick the signal out of the background junk.

Put a big enough telescope array on the moon, and you could see people's goose bumps.

Reviewing laptop disassembly vids, and the latest ultraslim ones have batteries no thicker than heavy cardboard, maybe 4" wide, 8" long.

They are called "polymer lithium-ion" batts.

Each generation of technology is happening quicker and quicker. Energy density always goes up.

Cool stuff is going on.

Yet, genuine breakthroughs in battery technology are few and far between. Year over year, we squeeze more juice out of the pack, but a true successor remains just out of reach.

It’s not for lack of trying, either. Over the last THREE decades, engineers and researchers in South Korea, China, Japan, the United States, and Europe have scrambled to develop safe, light, and powerful battery.

There is a general sense that LiIon technology has to be abandoned for something better.

I hope so. We pay enough for battery packs..
The cobalt shortages are going to be crazy if the auto company's build the cars before the batteries.
Sucks the valuable resource seems to be easy to mine in the Congo. I have spoke with mining company and its near impossible to get in the ground because of corruption and banana politics. Even if you do get in the ground the government will find some way to squeeze money out of company till it doesn't make any money.

Nothing has ever changed. From wood to coal to oil to natural gas to nuclear to renewables.

Its never changed.

Perceived availability is directly related to supply/demand.

We are paying today for li ion batts the same as I was paying for slow charge ni cads 30 years ago.

Re: The Switch To Electric Vehicles.....


I think the key is making the cars not require as much battery as they do today. It's my opinion the brushless motor is a great start. Worked great in tools.

https://www.tesla.com/blog/induction...ushless-motors

Brushless or Induction?
Back in the 1990s all of the electric vehicles except one were powered by DC brushless drives. Today, all the hybrids are powered by DC brushless drives, with no exceptions. The only notable uses of induction drives have been the General Motors EV-1; the AC Propulsion vehicles, including the tzero; and the Tesla Roadster.

Methinks tools of the trade got their ideas from EVs, not other way around....

Mike do you really think a 150 dollar cordless drill has better tech than a 100k dollar car?

The Tesla is Brushless and runs on AC current. From what I understand.

Yes, and use an induction motor except the Model 3 which uses a permanent magnet reluctance motor.

My wife wants an S model, but it's not practical if we retire in Boise.

Re: The Switch To Electric Vehicles.....


Why that? I think it'd be perfect... you could fill the trunk with potatoes wired up to constantly recharge the battery. You'd never need to stop at a charging station. It's fool proof!
