If this thread had not generated a gazillion views I wouldn’t keep adding to it ;)

It would seem there is a spanner been thrown in the electric works according to today’s report on Aunty.

https://www.abc.net.au/news/science/202 ... /104054438

Interesting but not surprising. There was also a report my wife showed me on somewhere else about a dude touring WA in his Tesla.

All interesting stuff and I’m following it as my daughter and son in law have just picked up a new BYD full EV. The ACT government were offering interest free loans, a few years free rego and a free how to vote card for the next election. Or some such tosh. They have a fairly brutal urban commute so for them it makes sense I assume.

The feds are now attempting to provide a shipload more chargers. Not the Valiant ones. They are a fair bit behind and should not be surprised people have stepped in their orange juice and bought hybrids instead.

Mr Touring WA told the reporter he topped up at caravan park o’night at the 15 v outlets but interestingly the park I stayed at up the Hunter Valley earlier this month has special signs prohibiting the charging of EV’s .

As usual there is no free lunch.

Edit: also reported this week, some councils cracking down on genius ev owners running live 240volt leads across public footpaths. Yes you read that right. Bloody killjoys :shock:

Interesting stuff ozzie,

Reckon hybrids have a big role to play in Aust while "the grid" catches up. I drive hybrid toyota and can vouch for them. In city traffic the engine is mostly off and battery power runs the systems. Braking recharges batt too (no brake pads to wear out) It's mature well proven tech.

Rooftop PV's still expanding, There's a huge PV shaded carpark at Willow's shopping mall here now, keeps sun off cars while powering the mall up (with Aldi in there too!)

I've followed "Chasing Latitudes" this year. Chris is a professional US yacht delivery Captain and sailing consultant based in Puerto Rico, Carribean. He's got decades of experience and knowlege, and is a non-pc straight shooter, (no beating about the bush or hiding the cold hard truth for the easily offended out there). He's in the big boat world, but allot of these principles apply to any craft. He doesn't have sponsor-ship deals like most other sailing u-tubers, his utube site is a window to his consultancy business, takes newbies/dreamers (for a fee) on delivery trips to see if they can handle it..(80% can't, so it saves them big bucks, not getting into voyaging type boats, and perhaps limiting to coastal or harbour ambitions)

Here is his latest summary/opinion piece on electic motors and batteries..

https://www.youtube.com/watch?v=r8Qhtwcr9VM

Batteries and the ludicrous system costs get slammed. Seem to be fair arguments. Uma is featured (they get free e-motors etc from sponsors (25k USD each motor and leg!)) Dont drink the "Green Cool-aid" before watching this.
Chris (and sailing with Thomas, Norweigian) seem to be on the same page.

Andrew, good link. This thread now has 308k views. There is a lot of interest in the subject obviously but until you can fit a thousand miles of supply into a reliable storage battery the size of travel suitcase, i don’t think it will float. :lol:

Something relevant I can personally relate to. I have just gone through the exercise of replacing our lawn mower. We had a small cheap 240v corded mower to do our small patch of footpath (I got rid of all grass on the property 25 years ago …I’m a boaty :twisted: who wants to mow)

Some years ago our situation changed and the bush area that’s adjacent to our property ceased to be maintained by the private owner. This quickly went from being grass to a fire hazard. Not to be outdone by adding rodents and snakes to the mix. I bought a cheap secondhand self propelled off gummy and maintained a wide strip of it as a firebreak for a few years with the the owners concurrence, and on the condition I can park my boat trailers there. It also did my footpath. This worked ok till the mower died a few months ago. I thought I’d replace it with a new self propelled electric that used the same batteries as my power tools as I have several high amp hour batteries and a charger already and they would all be interchangeable.

On doing the net and YouTube research however including talking to other E battery powered mower owners the joy wasn’t there. Neighbours who had one, said they pushed theirs most of the time and only used the self propelled to go up hills otherwise it was not sufficient range to do their whole lawn even with dual batteries.

Lawn Contractors doing reviews with high hopes for the electric. said they had reverted to their Honda professional grade self propelled as the E mowers were not up to scratch other than for well maintained lawn. Which is what we bought. Honda, self propelled, key start, multiple speed four stroke. I have to fight the Mrs now as she enjoys doing the lawn. Idea also being that if my health deteriorated she could continue to maintain the property ok till we relocate. I like to think of it as an investment in staying here a few more years. Also it only cost $100 more that a package deal electric SP with batteries and chargers.

As a side issue we recently stayed a weekend in inner city Sydney as part of our 45th Anniversary celebrations. The multi storey car park we used had four marked spaces on each level for charging EVs. On the day we arrived they were all marked “Out of Oder” on our floor, same the morning we left two days later. Dunno if the ones on the other levels were the same but this could seriously stuff your weekend up if you had traveled by EV.

We’ll get there eventually.

Maybe.

And also, we're in the same queue as every other country, trying desperately to get our hands on these chargers, because we know that there is a growing number of EVs being sold globally and you can't get these chargers quickly enough."


Hardly a problem at all :lol:

Interesting article Ozzie,

Read something similar in "1/2 outback" Central Qld. EV's for evacuation in emergencies (where the grid power is gone) are just a dangerously BAD idea. Think cyclones, floods and bushfires (eg LosAngeles).. recomended having a 2nd ICE car for use in emergency evacuations, just leave the EV behind to it's fate, as Arnold would say "if you want to live!". In disasters the mass of fleeing EV's can totally overwhelm public recharging systems, long ques at E-stations or at worse totally blocked highways that need clearing with bulldozers.

Yes, the E-mowers..I've owned and trialled a 72V victa e-mower with about 400-500m2 lawn, at first it was ok (but required a halfway 20min recharge/tea break) then with battery ageing after a few years it wasn't really upto it. One day it "bricked" and wouldnt accept recharge, but somehow (utube) I got it to recharge again. Greenshed which sold it, didn't have 72v replacement batteries and the genuine ones online only were 100s$$$. So e-mowers has just sat there unused for well over a year now.

Also have a 21" self-propelled petrol mower (it's a beast that i use on another 4000m3 lawn block) on the small 400m2 lawn (the the e-mower was for) "the beast" eats it in 15-20 minutes straight. Edges are done with a petrol line trimer (in wet season growth) and an 18v e-line trimmer in dry/slow growth season (both Ryobi) No more e-mowers for me, but will keep going with the 18V e-line trimmer, its reliable and part of my Ryobi 18v garden/hand tools collection, which are great. So far i've replaced the 2x18v batteries once after 4 years ($200), (kept the weak old ones for 18v lamp/fan/radio). It's good value as at least 10 ten hand tools share these batteries and there is little other mainenance costs. They have good after sales spares backup on going too, the battery exterior design/plug has remained the same for years and i hope to stays like that (they can improve internal wizardry tho)

At present I'm not going above garden tools/hand tools level with E-power. It is very good at this level. But above this the grunt/range/cost/spares backup/continuity factors don't gel. The petrol gear has cost about $100-300 per year to run and maintain, always spares and mechanics to keep them healthy.

In 2025 Australia, E-cars are still limited, probably best around town with home re-charger. The highway recharge networks are badly falling behind and it's only for the devoted. How can the govt/EV makers expect faster uptake if the recharge network/green energy isn't built faster.? I seriously wish that EV's would fill the around town/city commuting market first, but big EV batteries are still years away from breaking-even with ICE fuel tanks. keep an ICE disaster/long range vehicle handy if you live remotely or in a disaster-prone region.

Well what’d ya know? Power your boat AND keep it spotless with baking soda all at once . :)
I’m not laughing. I didn’t think I’d be carrying out phone conversations on my watch ten years ago.
