Garnaut was adamant there would be no floor price for carbon. There's no way the ETS will cover $12 bn / $19 however many tonnes that is. Does that mean electricity prices will go up by 1.9c a kwh if 1 Mwh -> 1 tonne of CO2 ? I don't see it happening without massive giveaways.

The fact that hot graphite blocks and now undersea turbines have been considered for King Island seems to confirm wind charged vanadium redox batteries are a disappointment. I hope Lennon realises NZ geothermal is volcanic not granite like KuTH and other shysters are pushing. Both places can wonder what happened to autumn rain.

We must eat more fish and chips so the newlyweds can get home again.

I like fish and chips so I'm happy to help :-)

The tidal power test isn't to power King Island per se - just to try and prove the technology - and that area has some of the best currents around. I don't think this reflects on flow batteries one way or the other.
