Prices of the electricity we use to charge

I can see that eventually Li-ion batteries for vehicles will be banned. It's OK to take the risk with a few cells in power tools & the like but putting thousands of potential little bombs in a car is an unacceptable risk.

Yes - it's not like we have been using dangerous technology for transport for a hundred years and more.

The fire risk in lithium ion batteries will be eliminated in about 3-4 years in semi solid state or solid state batteries. They put a temperature sensitive membrane between the two electrodes to stop short circuit.

My understanding is that dendritic crystal formation piercing membranes is what is holding up the introduction of solid state li-ion. Won't a pierced temperature sensing membrane between electrodes still be a short circuit, rendering the cell useless, albeit perhaps more safely?

I hope they will solve the problem of dendrites soon. Solid state batteries don't burn, so there's little need to add anything.

everything will burn if its going fast enough even the sr72

SR-72 'Son of Blackbird' Could Be a Mach 6 'Bomber' Russia Can't Touch

Lockheed Martin’s SR-72, nicknamed “Son of Blackbird,” is poised to replace the iconic SR-71 with cutting-edge stealth, hypersonic speed approaching MACH 6, and an option to deliver powerful conventional or nuclear-tipped missiles.

now if i was going mach 10 and had to get out fast going 7672.69mph how does that work then

It always comes back to the basics with BEV's
I like the notion of ICE being "Air Engines" in that they use 13 times more air than fuel.
If only we could harness the hot air from poly-tic-shuns and sceance-tists there wouldn't be an energy problem! Haha :-()

440V? Railway overhead voltage is 25,000V. High voltage, low current, small wires.

Train power rails seem to be 650v - 1500vDC plus now.
Overhead power Trains appear to be 25kVAC

Still didn't hear a voltage quoted, did I miss it?

1,329 tiny snails released on remote island

The snails are native to the Desertas Islands

Those snails were believed to be the last of their kind, so they were collected and brought into captivity. "

I think the lowish DC voltages are used only for lowish power systems: the Tube, and suburban passenger multiple units.

Heavy freight is a different kettle of fish, needing much higher power, in rural areas with more restricted access to the electricity grid and so on. Low voltage DC has a lot of disadvantages for that.

I haven't studied it in detail, but there are a couple of things that would trouble me: (1) the 25,000V equipment on each lorry. How big, how heavy? Is it practical? I suspect difficult. (2) The network capability: lots of users close together, instead of only one train at a time; steeper gradients on the roads in places, so very high localised power demand.

I think an in depth study would probably conclude that a shift away from lorries to trains for hub to hub transfers, and improved turnaround times from train to road at the hubs might be a better answer.

I will watch with interest but not lose any sleep over it.

There is currently no proper high capacity solid state. The guy on the video confirmed that his was semi solid state. It doesn't have the fast charging capability and high longevity of solid state batteries. He can also set fire to it. Not if it was a real solid state.

Ilika’s solid-state battery safety test exceeds expectations
"Tests involved a nail penetration test, designed to simulate a catastrophic failure scenario.

"Ilika has designed solid-state cells intended to provide a safer alternative to high-energy lithium-ion batteries,” chief executive Graeme Purdy said in a statement.

“Thanks to SafeBatt and this study, we have now observed test results which contribute to a growing body of evidence demonstrating Goliath's superior safety performance."

Importantly, the Goliath P1 cells did not explode or overheat, and their external temperature remained below 80°C. This contrasts with typical lithium-ion cells, which can swell, rupture, or catch fire, often reaching temperatures exceeding 600°C."

More power just for the asking, ha ha ha, why bother with those "super" batteries! ;-)

Yes - it's not like we have been using dangerous technology for transport for a hundred years and more.

They should reintroduce the original name: Explosive Engines.

All the Pre-Registered BEV's are being auctioned off.
Bargains to be had with only few miles in 1 or 2 YEARS! What a pretty pickle, spoilt for choice?
Oh, and one might not get insurance for one's bev, or one's house. No service history may mean no warranty, wonderful
