Re: Tesla's new power cell for houses
there are just lithium-ion cells stacked and liquid cooled/controlled....much like what nigel calder has/had installed in his boat for design testing and documenting power rates and such.
Much ado 100 year old technology that is priced way out of line with what any one can afford. Perhaps down the road, IF PV panels and wind become price competitive.
They still need to be charged and recharged, they have limited lifespan and certainly a finite number of charge cycles. Electronic control, but even that has failed to regulate similar cells every now and then. And when these cells fail, they fail dramatically.
Get them for your boat now, as I believe they are in the $400USD and up range for a comparable size $100 lead/acid type. Controllers and chargers are pricey. and they don't like damp, corrosive environments according to Nigel in an article he did last fall.
