They have these electric motors setting all kinds of records, I never thought of having an electric motor try to compete with a gas engine but I do remember working a place where powered metal was compress enough to cause the powder to become a hard metal and be used as gears.  I guess the whole thing relies on the batteries the motor gets the energy from.

Yes absolutely and lets not forget that batteries are very efficient these days, talking of efficiency here is a video that compares battery powered EV's to Hydrogen powered, worth watching  Smiley

Good video Data, I have a feeling for what they are doing with hydrogen now,  I remember the days of separating hydrogen and oxygen from water.

Interesting. Puts some actual figures on the efficiencies of both technologies.

Short term batteries all the way. But hydrogen will play a part at some point, I feel. More likely mass transport, trucks and boats. And possibly aircraft.

Storing excess solar as methane or hydrogen will play its part too. These techs are expensive atm but will scale much better than batteries.

Can we implement all this lovely tech before another 1 deg C rise in global temp?

Thanks for the comments chaps  thumbsup

Short term batteries all the way.

Indeed, having lived with a Leaf for over a year and doing more than 9000 miles in it I can confirm that battery powered cars are completely workable today, we have a pretty big charging infrastructure now, it's big enough for the amount of EV's on the road and is growing every week.

I have never run-out of charge yet either  Smiley
