Lithium Again.

Just depends I suppose, on if the design engineers think that far ahead. As we all know some designers forget that things need maintaining.

Same thing with some motorhome manufacturers...

Yes Ray, sad but true isn't it.

The hard part with the big industrial types are removing and reinstalling the complete drive. I reckon that as time goes by and EV 'S become more accepted it will be done like an auto trans service is these days. Just depends I suppose, on if the design engineers think that far ahead. As we all know some designers forget that things need maintaining.

You only have to look at modern cars to see how they are designed to not be worked on, once you could climb in the engine bay of a car and work on it, today you almost have to remove the engine and transmission to change a spark plug or oil filter.

Graphene capacitors will enhance Ev's, not replace the batteries, there are youtube tutorials on how to make graphene capacitors that anyone can do and going to have ago at it when have the time just to see if I can do it. U have a couple of capacitor driven torches, which are over 29 years old and they still work 100% and are used every night to take the dogs for a walk. Just shake it a few times and off you go. Progress is always restricted by those in denial of the unfolding reality, or to protect their vested interests and we see that in every industry today.

Some of my lifepo4 cells (120ah portable pack) are over 12 years old, used most days and still retain 100% capacity, house pack is a year younger and gets a hammering, especially when we are playing music and they never falter. Reckon 30 years will be the goal and should make it there, if still around by then. Have 3 cells from that batch that have never been used and they still sit at 13.2v, yet never been charged or used in any way.

NP, I am going to steal this line from your last post and use it from time to time. I think it is brilliant, appropriate and to the point.

Every day in my working life I found something new to learn, whether I wanted to or not. Everything electrical changes almost every day.

Thanks David, I'm the same, learn something new every day and strive to do that, even if it means it taxes my brain, which it does regularly.

I'm one of those people who jump onto anything new and never disregard it until it is proven false, even if I know nothing about the technical side of it. To me it's being able to see where the potential will lead that counts, even if it leads nowhere, from it will always come better understanding and progress.

Remember many decades ago when was first introduce to the wonders of capacitors, back then my late mate told me they would one day revolutionise energy use and storage. Everyone laughed when I repeated that, same with lithium, same with graphene, it will be the same when they discover energy doesn't need to be stored, but captured from the humongous generator that sits within the earth. Same with black holes and stars, I see them as dimensional doors, that move matter and gases between universal dimensions transferring it into a state that fits the dimensions they interact with and not big balls of hydrogen, or being able to compress matter to infinity. On side is a black hole, on the other is a star, but that's another story.

Graphene will probably revolutionise energy storage and use, with graphene capacitors and lithium graphene/sulphur storage cells, may well be the next generation if energy storage and we will see EV's with endless range and almost instant charging.

Capacitors have a long way to go before they can capture and hold for slow release the capacity the same size/weight an LTO cell can. Then they have to last as long as an LTO cell. If they can master those 2 tasks, then they need to n=make them as safe as an LTO cell and find a way to manufacture them at the same costing or better than the current LYP cells because LTO cells will be at around that pricing by then.
The hydrogen fuel cell is a brilliant breakthrough in technology, but making the hydrogen clean enough to not foul the membrane is very expensive and a long way off at the moment. The problem is in the transport, either as natural gas (methane) or ammonia otherwise the hydrogen molecules escape through the holding vessel walls. Burning it in a turbine is a much better option, the hydrogen mixes with the air and uses the oxygen to create a highly flammable yet self cooling flame front because the by product is water and that adds density to the exhaust increasing thrust that drives the turbine. Harness a generator and you have a self charging electric vehicle.
But why change a fuel we have a lot of through a complex separation process when we can burn the methane in the turbine. Gas turbines have been around for years, we even use them now as peaking generators as part of the grid. We already have the technology and the plants built to liquefy methane (LNG) and the vessels it can be contained in for transport. We already have the technology to turn hydrogen into methane by adding a carbon atom, so we can create methane using excess renewable energy and sea water or under ground salinified (not even spell checker or Google are sure how that is spelt) that is destroying crop growing area from the rising salt levels as the underground water table rises. The by-product would be many minerals and salts that also has a value, Sungro has already proven that market.

So we already have all the required technologies, why aren't we doing it now? I think NP hit the nail on the head "Progress is always restricted by those in denial of the unfolding reality, or to protect their vested interests"
Another great saying attributed to John K Galbrath but I don't think it is just restricted to conservatives
