Thread: EV 1500km per charge, Aluminium Air fuel Cell

[QUOTE=Phideaux;2946698][QUOTE=Silenceisgolden;2946666]But why does the world need this ASAP? Until the world is entirely powered by renewables, electric cars will be running on coal. "

Britain now has more renewable generation than non-renewable [\QUOTE]

Maybe so, but until electricity is generated ENTIRELY by renewable means, electric cars will be powered by coal or other fossil fuels, because until we are entirely renewable, ALL renewable energy will be used before you hop into your electric car. And if you should hop into your car first, then your fridge and your electric massage table will be coal fired instead of renewables fired.

Population control is the discussion we need to have, but it treads on too many toes.

Having said that, fifty years ago I ripped the clapped side-valve engine out of my C10 BSA and put in a Holden started motor and battery, end electric vehicles do have an immense charm in their own right.

You’re forgetting that even if you powered every EV from coal, it’s still a LOT cleaner and far less emissions are produced - I’ll dig the figures up when I’m back in front of my computer. It makes heaps of sense RIGHT NOW to go electric. It would start reducing emissions immediately no matter what they were charged by. People keep dragging up this argument about charging them with coal time and again but it’s been done to death and the proof shows it’s still heaps cleaner and more efficient to do this than produce the same power with petrol or diesel in the vehicle.

Thank you, I would like to see your figures. The only info I could find was the table I printed, which doesn't take into account the conversion efficiency of either coal or diesel fired power.

The energy is cleaner, the production of the elements used is far more damaging than that - Aluminium is an extremely high output process.

The band wagon is what it is though.

It would be nice if there was some magic wand which translated into "convert all vehicles to electric, end all environmental problems".
But there's not.
We're a very long way down a track, which, if we had something like a position of "Life-support systems Chief Officer, reporting to the Captain of Spaceship Earth" the report would be,
"Captain, I've just discovered, the previous several officers in my position made invalid assumptions about the resilience and depth of the system, and appear to have ignored multiple warnings from their Science Officers! Unless we backtrack and apply new and revised recycling and energy generation systems, the balancing systems are going to fail! Possibly within my lifetime!!"
(The 'Science Officer predictions were issued in the early-mid 1960s, and (fires, floods, bigger storms, etc) are evident in yesterday's and tomorrow's newspapers. I remember them. (And I never thought I'd see Binna-Burra Rainforest Lodge burn...) All the 'Captains' - PMs, Presidents, etc - were informed. Which is where Greta's "how dare you!" comes from. Failure to act? Unforgivable. PS - the most important thing Greta said: "I don't want you to listen to me. I want you to listen to the scientists!")

SilenceisGolden: agree with you re population control.
Refer Paul Ehrlich (1968), even if many of his predictions were wrong, or premature.
In fact - some actions have been taken - and they have worked. They're just insufficient.
SilenceisGolden: disagree if what you meant is, we have to go to 100% renewables before we get serious about EVs.

Re complexities
Insert variables like:
* people driving home from work and plugging in their EV are making a big drain at peak period. Plugging in during high sun or high wind - better.
* House batteries can't be used for charging EVs (they're too small; the percentage of charge they'd deliver simply wears out the house battery.) * However, EV car batteries can be used to power houses. And draw power from solar.
(My existing solar is good for only about 30km daily, I believe...)
* Existing electricity systems were designed for point sources of major power, not multiple sources of minor generation.
* Some graziers are surviving because they got a good lease for their unproductive hill paddock now providing wind power.

There's a zillion other variables. But the solution is within reach - particularly if we have governments who support the future instead of the entrenched polluters who pay more in Party contributions than they do in tax.

Let's see what Homestar comes up with - the only figures I could find suggest that coal pollutes more than diesel, in which case we are not ready for electric cars yet (from an environmental point of view).

Still looking for the report I’ve read, but this is a start. Media stuff I know but a reliable source. Still on my phone so limited with what I can find at the moment

Bloomberg - Are you a robot?

Maybe you could find the BNEF report while I get home. If not, I’ll dig that up too.

I think the Bloomberg report supports what I read. It says that "The difference was biggest in Britain and the U.K., which have large renewables industries." The point is, that while the car is using renewables it means that something else is using fossil fuel derived electricity instead of renewable electricity. This will only change when ALL electricity is derived from clean sources.
