So a 30 kWh battery would weigh 261 kg... so this isn't a leap forward in energy density by mass

I heard 75 kg for a 3.5 kwh unit so 640 kg for 30 kwh

Not impressive for batteries - but for supercaps that is about 50 times better than existing units

These are roughly 1000th the price of existing supercaps - I hope it's not just somebody getting his number wrong
I know Skeleton Technology is aiming for a 20Wh/kg supercap by 2020 (https://chargedevs.com/newswire/ske...pacitors-targets-heavy-transportation-market/), and so this would still be about 6x heavier (1500kg for 30kWh) than the one from KiloWatt Labs.

I'm a bit skeptical about the 115Wh/kg supercap spec. I think someone probably missed a period "." somewhere, or mixed up their supercap spec with a battery spec lol.

In terms of pricing, well even if they're an order off, it's still cheap for supercaps ;)

All of the electronic bits - the patents and the "secret sauce" are almost besides the point

To me the point is the 200:1 reduction in weight and the 1000:1 reduction in costs
I agree with Duncan, I think the way it works and stuff doesn't matter (at least for now). if they can prove the weight and cost, then it becomes a viable product. if not it's just another product that will not see the light of day outside of exhibitions
