We're not 10 years in the future though are we? So saying a Tesla will be 1.5T then is pointless.
Far from pointless. In the coming years, well within our lifetimes, the EV will have transformed, while IC cars will have not moved and inch. The only advance in IC can be with rotary engines. They are being lined up for hybrid use. But most of the energy in the tanks is still wasted, just a little less than the past its sell by date piston/crank engines.wsurfa said:
A real comparison would be Note 2 to Note 7 - battery increase c 10%. That worked out well.....so well the Note 7R has the same size battery as the Note 7, but is only c3% increase to the Note 2.
Both phones are effectively the same size.
However during that time processor efficiency has massively increased.
Electric motors have improved as has the management systems with kinetic energy energy clawback.Both phones are effectively the same size.
However during that time processor efficiency has massively increased.

My mate is CTO of a Silicon Valley technology company. He says the one thing NOT advancing is battery technology. It is simply not keeping up with the rest of the sector.
There have been a few breakthroughs in batteries, they are just not in production. it takes time for that, then the makers test the batteries in their products for a loooooong time, to ensure reliability.mybrainhurts said:
Our starry eyed swooners seem incapable of understanding that, cometh the self driving car, cometh a blanket ban on driving.
I've never seen so many dumb lemmings in one place.
People with obsessions of `driving` outdated pollution spewing cars should not hold sway.I've never seen so many dumb lemmings in one place.

The piston/crank engine is highly inefficient due to its inherent design. It cannot be improved to any level of efficiency or tolerable emissions for the planet and humans breathing in the exhaust. It is way past the end of its sell by date for sure. The line has been drawn. It should have gone decades ago in favour of rotaries. But a rotary is an ICE as well and would have only have extended the pain of these unsuitable engines.
Just about everything about the ICE is wrong.

I was talking to a ship's designer a week back. I was talking about EVs and that batteries are far more efficient than they were and so efficient the electric plane is here. Electric boats are not new; they date back to the 1800s. He mentioned that electric propulsion of ships is here in that electric motors turn props in Diesel/electric and going over to full battery is just another progressive step. He said that it is now feasible to use battery storage on ships, the fluid-flow versions used for grid battery storage. Weight is not such an issue with ships. They are slightly less efficient than Lith Ion batteries, but when in port the batteries can be charged up. He said it would be ideal for coastal vessels and say cruise ships around Europe.
Many places like Venice are kicking up about the pollution cruise liners create. Solar panels could be on the ships to assist the ancillaries. I mentioned advances in batteries to come. He said that was an advantage, as when batteries need replacing a far more efficient set will probably be available. They will also take up less space than massive diesel engine generators, the exhausts and fuel storage tanks. When a cell of a battery set fails it is easy to replace and maybe with a more efficient cell. A whole battery set could be replaced gradually cell by cell as they deteriorate. This spreads the costs of course.
He did mention hybrid ships that run on batteries when running into ports. The diesel generators can then be downsized.
Here are the fluid-flow batteries:

Rotaries should have replaced piston engines because of better efficiency?
If the R&D had gone into them of course they would be more efficient as they have great advantages in size, weight and smoothness. Mazda is looking at them for hybrid purposes to run at constant speed as hybrid genny's. All too late as full EVs will take hold. A rotary genny may have 10 years life after introduction.Edited by RayTay on Friday 21st July 02:19

just lots of batteries that use rare earth metals and shrouded in titanium
I've had an EV since 2015 so I'd say I was one of the earlier to convert, but listening to you I'm tempted to go back to being a gas guzzler. Your attitude is not endearing which will actually prohibit people wanting to follow in your footpath.
Spend more money on an ICE car. Be my guest. You obviously do not like facts. I have an attitude that likes hard facts.

If you want facts, read mckinzey, one if the worlds leading strategy consultants, their view on costs...EV has a long way behind parity
But one day....

Thank you. That is nearer than you think. I know McKinsey having worked with them. They highlight that in 6 short years battery pack prices have tumbled, dropping 77%, and will continue to do so. That is using the current battery technology. This report is over 6 months old. Since then China have announced it is setting up major plants leaving Tesla looking like a side show and also breakthroughs in battery technology have been announced. Then there is the mass production of electric motors and the rest of the car, of which there is little of it to make, that again will bring down costs. And also the ramping up of EV charging point infrastructure. All looks very good indeed.But one day....

This report does not mention this, but others predict the tipping point towards EVs will be only 6 years.

You seem to have this mental block when it comes to efficiency. Having something smaller and lighter doesn't help much if you need to burn significantly more fuel for the same power output due to problems with the fundamental design of the engine. You are living in a dream world if you think the wankel could ever best piston engines in terms of efficiency.
You must keep up with matters. A wankel with HCCI ign and running as a constant speed genny outstrips a piston/crank engine in that operation. Then the small size and weight and smoothness in cars has great appeal.Edited by RayTay on Wednesday 19th July 18:00
