I wouldn't want 10 square metres of lead acid batteries laying around my laundry,
Oh come on, they're actually quite cute, combining the visual qualities of an aquarium with bubbler, along with happy gurgling noises as though they've just enjoyed a good meal
The big picture appears to be, that we're heading for trouble with our national power supply. The coal fired plants are getting long in the tooth and total mismanagement of our gas resources [grrrrr] has meant that what should have been a cheap source of power for all sorts of uses around Australia, isn't [and isn't even making us money as an export].
Roof-top solar could and should make a big contribution to the problem but if it's to be widely taken up it has to be as cheap as is possible. If it's going to cost an extra $5-10,000 to build a compliant shed in the back yard it stands to reason that a whole lot less people will get into battery storage. [Incidentally, I notice the recommendation is, that the shed should only be accessible to power supply persons, which would make it useless for anything else]
Surely it should be possible to design a compliant "box" capable of withstanding a fire, or any other sort of chemical problem, which could be placed anywhere?
Maybe what's ticking over in the heads of govt. is a memory of the pink batts program. Even if batteries were successfully installed in 999,995 house the program would be a public disaster worthy of tipping out a government if 5 houses went up in flames.
