There is a useful thread on Powerwall in whirlpool.net.au. Seems the first retail customer in Australia has just had a system installed at a cost of $17,000, but $5000 of that was solar panels.

Yes there is an article in today's Australian which looks very much like a publicity handout by the Tesla resellers.
The bloke commented he would not be able to run an electric jug, but had bought a caravan small one.LOL.
I read in a USA publication a little while ago that currently the Tesla battery is made up of a zillion Panasonic small (AFAIR the reporter said just bigger than AA) batteries, most probably what they call sub C.
So currently the batteries are the same as in your trusty drill or overseas Prius ( I understand that Toyota plans that OZ models will have nicad) only lots of them.
It will be interesting to discover whether Tesla is able to achieve the great cost savings that he hopes from his ( US government subsidised) mega factory where he plans to build all components for the Powerwall.

People want to buy Tesla batteries because the brand name has some serious street cred amongst the tech heads. Nothing wrong with that, it's the same brand recognition that sells Range Rovers.Quote:

Electric utilities that whine about solar users bumping up peak evening power usage should be ecstatic, but instead they're whining about lost revenue.
The cells used in these batteries are designated as 18650 size, nothing to do with NiCad battery sizes. Mass production keeps unit costs down.
As for government subsidies for Tesla to manufacture his own cells, I should bloody well hope so. After all, fossil fuel production has seen the benefit of subsidies since nearly forever. Would you prefer a modern high tech factory in your district, or just another filth spewing coal power plant? Even now generators are selling their old coal mines for a pittance to new owners who will suddenly evaporate when asked to clean up the mess. The taxpayer ends up paying anyway.
You mean coal that supplies over 80% of our power even with subsidies and mandatory buying of wind power?
You mean coal in the terrible network that supplied a record consumption of electricity last week keeping all those air conditioners going?
You mean coal that produces CO2 which makes plants grow and is pumped into greenhouses and has greened the world?
You mean coal where CO2 levels have risen but the temperature hasn't for 18 years?
I guess you will prefer the utopia of subsidies that will never end for wind, solar and batteries , and where the real payoff period exceeds the useful life.

Snort, you've been reading too much Wattsup's trash again. Enjoy your "coal is good for humanity" fable, if it lets you sleep soundly at night. ;)Quote:

PS Looks like Sydney will have a record wet summer in the middle of an El Nino . Who would have thunk it. Not any "climate scientists " I have read.
Shows how little they really know.

HERE'S ONE FOR THE DEBATE !
Attachment 107163
The entire rationale for wind turbines is to stop global warming by reducing the amount of CO2 being returned to the atmosphere from the burning of fossil fuels.
In the attached picture, recently taken in Sweden, freezing cold weather has caused the rotor blades of a wind turbine to ice up bringing the blades to a complete stop.
To fix the ?problem? a helicopter is employed (burning aviation fuel) to spray hot water (which is heated in the frigid temperatures using a truck equipped with a 260 kW oil burner) on the blades of the turbine to de-ice them.
The aviation fuel, the diesel for the truck, and the oil burned to heat the water, could produce more electricity (at the right time to meet demand) than the unfrozen wind turbine could ever produce. (Before it freezes up again).
The attached picture is a metaphor of the complete insanity of the climate change debate.
In decades to come this one photo alone with sum up an era of stupidity, when rational thought, logic and commonsense was abandoned and immense wealth and resources needlessly sacrificed.
And please don't measure the CO2 to install it in the first place.
If you really believe humanity have stuffed the planet, don't have kids.
At least other options are about to start shipping, https://www.zcell.com/
10kWh and safe- been used in use in industry for 15 years now. Powerwall is cool in their cars but not going to cut it in our homes or business IMO. The best bit for business and homes I.M.O. is the inverter for the Zcell is a full function UPS.
