@NZEVPodcast you may want to consider freebie speech-to-text for your podcast, to make it more search friendly: Google Docs Voice Typing (GDVT) or Windows Speech Recognition (WSR).

Regarding your last podcast, and the origins of autonomous vehicle, guerilla tactics played great part in the US conflict in Iraq and Afghanistan.

Many in the military still die from improvised explosive devices, IED, from unexploded ordnance guerillas recover and use against trucks.

This is the reason DARPA sponsored a contest in 2005: trucks are expendable but people, not so much.

Well, image if, instead of invading Iraq and Afghanistan, just half that cash was put into autonomous vehicles. We'd all be flying around in them by now.

The US is always spending lots of money on "defense."

A US aircraft carrier or naval strike group is equivalent to lighting a cigar with a $100 bill.

For instance the new US aircraft carrier cost 13 billion, three years behind schedule, and 2.4 billion over budget.

A naval strike group costs about $4,500/second.

But on very rare occasions, war does provide some benefits, if mostly completely accidental.

It been very clear the US values the military over long-term socially worthy causes. I'm not defending them.

For a country that is vehemently opposed to welfare the USA sure hands out a lot of corporate welfare. That's all the military and war is - an excuse to spend taxpayers money with whichever company has supported or lobbied senators the most.

There's also "pork-barrel" politics tied to many US military manufacturers.

https://en.wikipedia.org/wiki/Pork_barrel

This getting off-topic, but it's a problem here also.

New Zealand Taxpayers' Union

"A $10 million loan from taxpayers to build a gondola -- this is pork barrel politics typical of Shane Jones' Provincial Growth Fund.

Ruapehu Alpine Lifts owns both major ski-fields in the North Island and enjoys tax free status. A ski-field owning monopoly that doesn’t pay tax is the last organisation that deserves taxpayer subsidies."

Coming to market soon, Audio's new EV.

It's got some nice tech, including virtual mirrors.

The car is to be called "E-tron", which is a cool name, except in France where etron translates to 'turd' :-)

I saw the word "loan" there.

The ski field tax treatment is at least partially defensible on tourism grounds. Weren't they originally state owned until they were privatised? That would be the underlying problem if it was the case. Selling them converted a public good into a private asset. That's usually dumb in the long run.

Should be renamed "NZ don't want to pay any tax union"

Yes, and then we can still have people paid for working the gondolas years after the gondolas have stopped being run.

So, a little more on-topic:

From Toshiba: http://www.greencarcongress.com/2018/07/20180706-toshiba.html

"The team fabricated large-size lithium-ion batteries using the HD-TNO anode and a LiNi0.6Co0.2Mn0.2O2 (NCM) cathode with a capacity of 49 Ah for automotive applications. These cells had a high energy density of 350 Wh L-1, a high input-power density of 10 kW L−1 for 10 s at 50% state of charge (SOC), and fast-charging from 0% to 90% SOC in less than 6 min."

So....it's scalable. Can it be commercialised effectively? A six minute charging time drastically lowers the need for higher-range vehicles - adding 200km in six minutes would only add quarter of an hour for two stops on a drive to Taupo to stay within an 80% upper limit - you'd spend about that much time on a petrol station forecourt.

The batteries can take a very fast charging rate, that is great!

BUT: To charge a 50kWh battery in 6 minutes (1/10th of an hour) requires 500kW flowing in. If the charger were running at 500V then it would need to be flowing 1,000A current to provide 500kW, such a current flow would be problematic. If the voltage was increased then there would be other problems with increased danger and lethality. There is also the difficulty of the infrastructure supporting that much energy draw.

I'm not saying that we could never have 500kW chargers, just that there would be difficulties and expenses in providing such a thing.

As the range increases, the need for fast charging during a trip decreases. Eventually, we may end up with enough range so that we only need to charge overnight. If you had a 200kWh battery then you could drive 1,000km on a charge and if you plugged it in for 10 hours while you had an evening meal, watched TV and slept - you would only need a 20kW charger. It would typically take over 12 hours of driving to cover 1,000km with the normal mix of speed zones, for most people that would be more than enough time driving for a day. The number of times I've travelled more than 1,000km in a day is about once in the last 50 years - and I wouldn't be all that keen on repeating that.

I would predict that the future is in having enough range to only need to charge overnight, rather than super fast 500kW charging.

I just read that EVs have a horrible ride because the tyres are kept rock-hard to extend the range. Don't know how true this is.

I don't know, battery size/range seems like a fairly easy way to distinguish model from model. Although it wouldn't be unheard of for manufacturers to take advantage of economies of scale and fit the same items to multiple models and for the features to be essentially software-driven.

Some truth in it, but probably only makes a noticeable difference to extreme hypermilers.
