So Tesla may be able to manufacture 10% of the worldwide demand. 90% of a market still seems like a worthwhile target for other battery makers.

@ZLabe tweet:
For the first time, every month so far this year has been at least 1°C greater than the 1951-1980 climate baseline.

Not knowing much about capacitors (yeah, less than even that), I had this idea the moment after I heard that Tesla bought Maxwell - that one could load up a (future 1,000 km range) EV's capacitors really fast (like in 5 minutes - "megacharge"!), then get the car back on the road, and have the capacitors then, at near-optimum rates, charge up the battery.

Same!

It just seems so... logical!  But maybe increasingly fast battery charging brings it close to the time required to safely charge such a capacitor. I look forward to learning why it doesn’t work.  Maybe in Tesla’s upcoming battery and drive train investor day? 

It may be as simple as not being cost effective. Totally apart from the capacitors themselves, the connectors, conductors, contactors, IGBTs and fuses for, say, a couple thousand amps or more at 400V have got to be bulky, heavy and expensive.

I'll go out on a limb and say a lot of us like to hear about progress even when it isn't the answer to every single problem. Lighten up, yeah?

With all of this wonderful news, when should we expect the Keeling curve to curve back on itself?


Renewables and batteries are wonderful additions to our power mix, but in most venues they aren't keeping up with additional demand.

Y-o-y increase for last week (start April 28) was posted today as 4.48!

edit: ha, never mind, I see that last year the weekly average was oddly low
