Yes, agree but the guy on minimal salary with mortgage and 3 overextended credit cards will never qualify for the loan to buy a new electric car.
Shucks he buys 2-3 clunkers a year as they die off one after the other.
He has no choice as he can't afford the repair bills but sharks will finance a new clunker.

Are you saying rebates should only be available on items that everyone can afford?

You know the current target for 5G is 1gbps in metro areas? That's not 10x increase it's a 25x increase which will be rolling out in the next 10 years.

We already have point to point links in the 10s of gbps.

We're also already exceeding the traditional Shannon limit using CDMA + compression.

If you want to stick your head in the sand and say that nothing will ever improve that's your prerogative. However don't be surprised when the world moves forward with or without you. No amount of yelling "get off my lawn" is gonna change that.

I think you're even under selling 5G. The proposal is for it to have 10,000x the capacity of current networks.

If you understood how it worked , you would realize that that high speed data is via using several frequencies simultaneously . Fine if close to the cell tower(s) and if the cell tower is operating much below it’s max number of connected phones in the middle of the night.
As the cell tower loads down mid day at lunch time . Each phone is only going to going to be connected to the tower with only one download frequency and that frequency maybe 10% duty cycle as it is also being shared with 10 other customers .
You can open as many water taps as you want in the house , barn and shed simultaneously. The total accumulated volume in 10 minutes isn’t going to be different if there is two or ten taps open. There is a bottle neck.

You seem to be stuck on this same argument. No one argues that present battery technology will lead us to the holy grail. Improvement will require new battery technologies.

More like discoveries not improvements.

Kind of like jet travel getting faster? We're all still stuck at .9 Mach, just like the 707 days.

Nice job moving the goalpost.

You said that cellular data rates weren't going to increase more than 10x in the next 10 years. You want to walk that back now that you've proven that we're going to exceed it?

I work in that industry, I have an idea or two in what carries do to hit their data capacity . You might want to look up CDMA which let's you serve many users over a single channel simultaneously.

Oh my gosh, we might agree! How about: "Improvements will require new discoveries" ?

The headline is a bit overstated. The stock dropped 7%.

Irrelevant. We're at mach .9 because people don't like the noise of supersonic aircraft.

Waiting on the discovery of silent flight technology, It will come. Right?

I don't know. Are people clamoring for silent supersonic flight? It seems to me people made a collective decision that the benefits of supersonic travel do not outweigh the "costs."

What is your background and education? Ask an engineer and they will tell you that any tech has an absolute limit, a maximum possible limit and limit that is a bell curve with the best performance per dollar per time per reliability and per safety .
This is why the Concord was parked . This is why the US still flys the U2 instead of the ST-71. Even the super duper B2 is sub Sonic and the F35 is subsonic with the ability to briefly sprint super sonic.
It is why the best efficiency for an internal combustion reciprocating diesel is approx 50% and that is compound with exhaust heat extraction. Try to tell people that the 200mpg carburetor does not exist and they will fight you to the death because they want to believe they can have it and save money . And they believe oil companies are villains hiding the 200mpg carb. Take a look at the btu’s in a gallon of gasoline and tell us how 200mpg is possible . Same analogy for battery storage .

I don't think tomato has realized I'm letting him make my case, he still doesn't see it...

 

[vvanders]

Buick, you never did say if you wanted to walk back your claim of data speeds increasing 10x or not in the next 10 years.

You has such a succinct explanation of how this massive technical achievement was going to be made I'd hate to see you not follow through.

All this discussion of supersonic planes is irrelevant. The Concord was parked because it was not profitable, given the (non scientific) restrictions placed on it. The B2 flies sub-sonic because of its stealth requirements. The SR-71 was retired largely for political reasons.

You and HS continue to make the argument that the ultimate capabilities of batteries are limited because present technology imposes these limitations. It's very shortsighted to assume that new technology will not be developed / discovered in the future that will increase the capabilities of batteries. You, in particular, keep arguing that the laws of physics prevent further improvements in battery capabilities. This is simply an untrue statement. Physics does not say that the energy density of batteries cannot meet or exceed the energy density of fossil fuels, only that you cannot do it with present battery technology.

What is your background and education? Ask an engineer and they will tell you that any tech has an absolute limit, a maximum possible limit and limit that is a bell curve with the best performance per dollar per time per reliability and per safety.

My background and education? I have a PhD in experimental physics, and undergraduate degrees in applied mathematics and electrical engineering. I founded and presently own a company that manufactures scientific equipment. I have a pretty good grasp of what the laws of physics say, and what they do not say.

Going to be a lot of old PhD's with a classic old Tesla in the barn someday, waiting for the break through. You can park it next to the Honda Insight. Lol.

I don't own a Tesla. Or an Insight.
