I'm talking about taking renewable energy to manufacture hydrogen at source. Rather than use electrolysis, this discovery might form a part of a better process.

To use water and aluminium as energy storage. We already have a pretty good global aluminium infrastructure.

If water could be combined with aluminium to produce hydrogen on demand, then you refuel by replacement of the aluminium oxide waste with fresh aluminium and refilling the water tank.

Then you still need a better method to convert aluminium oxide to aluminium - but here's the great thing about this research. Better ways to convert in one direction usually lead to better ways to go the other way too (eg, microdots convert electricity to light better, but also the other way round too).

Depends how easily that aluminium oxide can be converted back to aluminium - if it is easy enough then this is a better cycle than electrolysis and might finally make hydrogen a sensible alternative energy storage medium than oil.

so we'll have to wait and see.

But javascript is an awfully convoluted language. Why does it become easy when you put a language like that into the equation?

I've still got my spectrum... Will this thing support my kempston joystick?

Is it okay if your camcorder recording includes the anti-piracy notice?

What is this "woman" thing you speak of?

I'm wasting my mod points now by posting, but I can't let that lie. A volcanic eruption that can kill everybody spouts vast quantities of CO2 - that's how it kills them - it suffocates them.

The guy in prison would be the first to go because CO2 is heavier than air and would fill the gaol as soon as possible.

Depending on the internal resistance perhaps your wire just melts really quickly, breaking the circuit.

That appears to be the sort of claim they are making, although I think they say the total volume will only be 20% less.

And they claim the practicalities, efficiencies and economies of Li nano-titanate and Li nano-phosphate batteries - which have half the specific energy of Lithium-Ion again. That's four times the specific energy of like-for-like batteries.

We're just going to have to see if it works and see what the price is.

Also the ICE weighs an awful lot more than 280lbs while four small in wheel motors weigh very little. then there's the gearbox, the driveshaft, the lead-acid battery (hint, hint "LEAD"). The coolant, the brake fluid (not needed with decent inwheel motors).

The electric version will be /much/ lighter overall.

(The two go hand in hand - they could both come under the umbrella of "phisicianism" :)

I've looked at you example again and there are not enough samples to determine that it is a skewed normal curve so we can't know whether it is actually a counter example.

I suspect it isn't but I have ladies to meet and dance argentine tango with in a few hours so I'm not going to spend the time forming a pedantic proof or disproof of any of this.

Hah! Who's the smart one now?
