Soooooooooooooo.............

As it turns out EV is not so good. Who would have thought???

I run my car on a truly recycled fuel and it runs well and goes far and is efficient. Engine probably good for half a million clicks if I take care of it too.
Yep recycled dinosaurs. They give oil which fuels my car.
It's a good system.

Isn’t that cannibalism?
One dinosaur feeding on other dinosaurs.... ;D ;)

All electric 70 series, apparently the electric drive system can be retrofitted to existing vehicles? It's built specifically for mine operations, but who knows ? - https://youtu.be/tVhquG_rCsA being done by an Aussie company in WA - https://www.voltra.net.au/ecruiser/

I still electric vehicles only being practical in an urban or controlled industrial environment though, due to the problems with remote charging though?

I notice they're not saying what those series 70 conversions cost though and if you don't need a fourby it would probably be cheaper to get a Tesla S or the Model X if you want the mandatory SUV.

As far as EVs go they're too dear for most but you might have to set your sights on a hybrid in future as they keep ramping up emissions standards to strangle the ICE and the domestic diesel will be the first to go with their problematic vac bags up the exhaust already. In that respect get ready for GPF with your petrol engines too-
https://www.greencarguide.co.uk/features/gasoline-particulate-filter-gpf/

That's why carmakers like Hyundai are sniffing the wind on hybrids now with Toyota's RAV4 success-
https://www.msn.com/en-au/motoring/news/hyundais-plan-to-topple-toyota/ar-AAJQUDc
All sorts of development going on in that respect and the old 12V battery might have had its day-
https://dieselnet.com/news/2017/10daimler.php
It's logical if diesels can't cut it with emissions and petrol lacks torque (or if you design one for torque the fuel economy and emissions suffer)you can get around that to some extent using the benefits of electric motors to get the load off the line until the petrol engine takes over with optimum rpm and as well you can recover waste energy with regenerative braking.
There's no Great Evil conspiracy against consumers within engineering, manufacturing and supply. Just the many tradeoffs incurred to satisfy diverse tastes, priorities and wallets. But first comes all the insatiable Gummint eggsperts, nanny-staters and usual suspects.

This new battery technology could be a big game changer...


South Australian researchers from the University of Adelaide have secured an A$1 million research contract with a Chinese battery manufacturer to develop the new technology and bring it to market within 12 months.

The patented design uses non-toxic zinc and manganese, two metals that are abundant in Australia, and incombustible aqueous electrolyte to produce a battery with a high-energy density.

The researchers estimate the cost of this new electrolytic Zn–Mn battery to be less than US$ 10 per kWh compared with US$ 300 per kWh for current Li-ion batteries, US$ 72 per kWh for Ni–Fe batteries and US$ 48 per kWh for Lead–acid batteries.

The battery is designed by Dr Dongliang Chao and Professor Shi-Zhang Qiao from the University of Adelaide’s School of Chemical Engineering and Advanced Materials.

The high-energy, safe battery opens up markets where the battery weight, size and safety are essential factors, including automotive and aerospace, and domestic and commercial buildings, and grid-scale energy storage.

Dr Chao said although there were other Zn-Mn batteries on the market such as the dry cell, they were not rechargeable or recyclable and did not present high-energy density due to a different chemical reaction mechanism.

“I can imagine this battery being used on all vehicle types from small scooters to even diesel electric trains. Also in homes that need batteries to store solar power, or even large solar/wind farms,” he said.

“With more sustainable energy being produced – such as through wind and solar farms – storing this energy in batteries in a safe, non-expensive and environmentally sound way is becoming more urgent but current battery materials – including lithium, lead and cadmium – are expensive, hazardous and toxic.

“Our new electrolytic battery technology uses the non-toxic zinc and manganese and incombustible aqueous electrolyte to produce a battery with a high energy density.”

Dr Chao and Professor Qiao began working on the project in South Australia about 12 months ago and patented the technology at the beginning of this year.

Chinese battery manufacturer Zhuoyue Power New Energy Ltd, whose current batteries are lead-based, has committed $1 million to develop the new technology.

The ongoing research work and initial product development will be conducted in Adelaide with manufacturing expected to take place in Australia and China.

Dr Chao said the project would combine the new electrolytic battery technology and the company’s battery assembling technology.

“In addition, the battery uses basic materials and simple manufacturing processes so will be much cheaper to produce and easier to recycle than existing batteries of comparable energy density,” Dr Chao said.

Dr Chao obtained his PhD from Nanyang Technological University, Singapore, and worked as a researcher at University of California, Los Angeles, before joining the University of Adelaide in South Australia last year.

South Australia is home to the world’s largest lithium-ion battery at Neoen’s Hornsdale Wind Farm in the state’s Mid North. It is also looming as a hub for electric vehicles and hosts the World Solar Challenge, the world’s most famous solar car race.

Just another example of Australia selling it’s assets cheaply to the Chinese. Assuming there’s some credibility to the technology I’d be happy to see the government spend a million on this in the name of climate change.

How the hell in this day and age can a bloody govt. not back the research and if proven lead by example and completely manufacture and distribute the batteries here in Oz.  Our fed govt is just a bloody joke.  I read about this technology quite a while ago and it seemed credible at the time. Hopefully it goes ahead as a winner.

I'll believe it when it comes to market, I have read too many times of the latest wonder power generation device/ battery chemistry etc that is going to be a game-changer that hasn't eventuated.

Having said that, one day one of them will come to fruition and will make some people very rich and a Googleplex times more difference to the environment than someone supergluing themself to a road ever did.
