Re: Wind and Solar vs Coal, Gasoline, Nuclear

That's right. Duke Energy owed -21% in taxes in 2018. -21% of 3 billion is 630 million. Nice subsidy there. So why does $630 m cause concern compared to the $70+ bn for wind and solar ? And doesnt Duke operate RE power generators also ? And. Again, why do you assume EIA has not included tax rebates...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Yep. For a fun (and insidious) oil subsidy google "depletion allowance." This tax break means they can deduct a percentage of the income from the oil they pump because the well is being "depleted." And even more fun - they can deduct more than 100% of the amount of oil in the well! Sort of an infin...

Commercially available ebike using power tool battery packs.

Has anyone tried , tested or even seen one of these Ozito ebikes that use their universal powertool battery packs ? Ozito is a chinese brand that produces a range of (cheap ?) cordless power tools that are retailed through the Bunnings stores in Australia. Its obviously just a cheap bike with a 250w...

Fire risk all depend on the individual cell chemistry. The burning/ explosive nature is dictated by the choice of electrolyte used by different manufacturers.

Re: A123 26650 FIRE

Maybe try to fully discharge all the cells (min safe voltage ). before you attempt assembly or disassembly of packs
Working on charged cells increases the risks dramatically.

If you just connect multiple cells in “series strings” of 10 , and connect those 6 strings in parallel, then you will need a BMS for every individual cell ! iE,..60 BMS’s :shock: 👎 Whilst cells connected in “parallel groups” of 6 first, then connect those “groups” in series to 10s, you only need 1 B...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

It actually sounds like they have done the opposite. They have prevented the home owner the option of using their own power before the meter and forced them to buy from the grid even though they have enough of their own electricity. The solution to your rant is real time two way smart meters which ...

Encouraging people to run their hot water systems and charge electric cars in the middle of the day is a far better way to manage it. Shutting off solar is one of many tools in the AEMO bag, and it probably won't get used a lot. Nope ! ..you are missing the key point... which is not just to reduce ...
