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  :)

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?

I found that informative too thanks  :thumbsup:

Thanks for the comments chaps  :thumbsup:

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  :)

Found these and thought they'd fit on here.

Snowy, nice vids  :)

Batteries have come quite some way in a little time, already reaching 100,000 miles plus and they are only going to get better.

I need to post this:

An Apology & Corrections, from that last video.

QuoteSales of electric vehicles reached a record high last month, accounting for one in every 12 new cars purchased in the UK.

Green number plates could be arriving for clean cars in the UK.

Green plates would be more noticeable to road users, and this increased attraction can help normalise the idea of clean vehicles, highlighting the changing social norms around vehicle ownership.

I was looking for cars again the other night. One thing I wondered is if you have to park in the street, then how would I charge an electric car ?  :scratch-head:

Not that I am going to buy one just yet.

One of the infrastructure problems to overcome.

If you have off road parking or are visiting town where there are parking bay charge points then there is no problem. You can get a grant to fit your own charger.

If you randomly park near-ish your own home each day then an extension lead is the only way but this has obvious issues not least being a trip hazard.

The solution (in my opinion) is street lamp charging. It can be done now with a smart meter that charges you, ££, to charge you car. There is no roll out solution ATM and EV uptake is still relatively low but this is all set to change. Probably have to dig up the roads, again, to fit bigger power cables to the street lamps.

This is me. I can't really run a cable across the road   :o :LOL:

So no electric car for me at the moment.
