It does make you wonder about the Governments and environmentalists lobbying to ditch “dirty” combustion engines vehicles in favor of electric, when the electricity needed to charge the batteries often comes from combustion of fuel to produce the electricity. Throw in the knowledge (the information is commonly available) that the materials required to make the batteries are not going to be sufficient to meet global demands and you might be forgiven if you conclude that those making the decisions are either stupid or have an ulterior motive, or both!!JWWhite wrote: ↑Thu Jul 26, 2018 6:29 am Ten years left to redesign lithium-ion batteries
Reserves of cobalt and nickel used in electric-vehicle cells will not meet future demand. Refocus research to find new electrodes based on common elements such as iron and silicon, urge Kostiantyn Turcheniuk and colleagues.
Electric vehicles need powerful, light and affordable batteries. The best bet is commercial lithium-ion cells — they are relatively compact and stable. But they are still too bulky and expensive for widespread use.
The performance of rechargeable lithium-ion batteries has improved steadily for two decades. The amount of energy stored in a litre-sized pack has more than tripled, from around 200 watt hours per litre (Wh l–1) to more than 700 Wh l–1. Costs have fallen by 30 times, to around US$150 per kilowatt hour (kWh). But that still exceeds the $100 per kWh goal for affordability set by the US Department of Energy. And batteries that are powerful enough for an electric car (50–100 kWh) still weigh around 600 kilograms and take up 500 litres of space.

I agree, it's crazy that they are ready to throw away workable technology, to go with something that does not yet work and more than likely will be unsustainable.Dannie Boy wrote: ↑Thu Jul 26, 2018 8:43 amIt does make you wonder about the Governments and environmentalists lobbying to ditch “dirty” combustion engines vehicles in favor of electric, when the electricity needed to charge the batteries often comes from combustion of fuel to produce the electricity.

All batteries are the current(no pun intended)means of storing electrical energy in a portable easily recoverable state.Ten years left to redesign lithium-ion batteries
Many of the people trying to stop electric vehicles have an ulterior motive, they're trying to sell more oil!Dannie Boy wrote: ↑Thu Jul 26, 2018 8:43 amIt does make you wonder about the Governments and environmentalists lobbying to ditch “dirty” combustion engines vehicles in favor of electric, when the electricity needed to charge the batteries often comes from combustion of fuel to produce the electricity.

We Might Save the Internal Combustion Engine by Flipping it on Itself
Well, it may run on petrol, but I overhauled a diesel version in 1969! They need to look up "Knocker Commer"!As Wired explains, the opposed piston engine layout has long been on the minds of vehicle engineers. It replaces the four-stroke engine's valvetrain with open intake and exhaust ports, eliminating the friction and complexity of a camshaft and valves.
Not much new about this design and concept. Looks like an almost direct copy of Fairbanks Morse Engines - principally used in marine, railway locomotive, and power plant applications.We Might Save the Internal Combustion Engine by Flipping it on Itself
