Battery Driven Cars

[Keith at Tregenna]

John, just a mute point, batteries don’t drive cars, they power them, humans drive cars

For years we had, who let the lady drive !

Wait to see what the robot's do:

3 robots collided at a UK grocery giant's warehouse, starting a fire that delayed thousands of orders.

how do you scrap one what and how do you get shut of the batteries there is a lot of plastic in the car bodies are they realy friendly to the planet? jp

Electric Cars on the surface look very good, but when you dig deep you will see there are a number of issues with them that most drivers would not be aware of.
No matter how the companies sell them I doubt they will tell the full story.
Biggest problem is the rechargeable battery.
Each recharge, and most owners will put them on charge every day, is that with every recharge the efficiency of the battery demineshes until at about only 80% efficiency the distance between charges is reduced.

Australia is working on and investing in a battery based on iron pellets. Very cheap but large so only for use in houses etc with solar panels. Also investing large sums in hydrogen production, and a major iron ore exporter has labs working on green steel, where hydrogen is used instead of other heating sources.
Australia is working on solutions to the global warming, not just raising taxes as in most countries who say they will get to zero emissions, but have no other plans to get there!

#14 Would be interesting to see one of those driverless cars avoid a random kangaroo suddenly pounding across a highway!!!
Even drivers can't always miss them, they suddenly come out of nowhere and you wouldn't want to hit one. LOL

ha h! so true; last time I travelled outside Perth, I never saw a live one, just dead ones beside the road. Body shops must do well though.

Apparently: The 'holy grail' of batteries:

Scientists develop an 'iron-air' battery that stores electricity for days through rusting - and is a fraction of the cost of lithium-ion equivalents ?

The battery works through rusting iron and then reversing the rusting process
While discharging the battery breathes in oxygen and converts iron metal to rust
While charging electricity converts rust to iron and the battery breathes out
This process allows it to store power longer and discharge it over a longer time

This is perfect for keeping supply from renewable energy sources such as wind and solar which stop operating when the wind isn't blowing or sun isn't shining.

Could be the future ?

May answer much.

Will wait and see.

One of our large transport companies has an experimental electric truck on the road/
One of the problems for us here in Oz is the tyrany of distance, how do you cross the Nulabor on batterie with no charging station?
Then there is the question of time to recharge, maybe be fine for domestic but for major transport time is money.

Talk of using Hydrogen in steel making has been on the cards for a number of years now but getting it right will take some time.

driving down a country lane in Scotland just on the other side of a bend here is a stag standing in the middle of the road the wife said dont hit it?? HAVE YOU EVER SEEN THE SIZE OF A FULL GROWN STAG? it would have killed the pair of us.. jp

As you say Victoria plenty of Camels out in the outback, an estimated 2 million, I may and go and put my name on one ready for when the petrol runs out, or that twit in America finds and stirs up life on Mars.

Victoria, that sounds very much like the description of most politicians.
Down a country road and sitting in the Middle a very large male Roo, no way to get past him have to wait until he moves.

Another car come sup behind me and after a few seconds IO can see the driver getting a bit irate and waving his hands at me.

My Land Rover can block the view of smaller cars behind so he had not seen the Roo.

I got out and went to speak with him when the Roo decided to move, not away from us ,rather more towards us.
I never saw a car go so fast in reverse as this one did.
But the Roo, obviously disturbed now bounded off into the bush.
