There's quite a few practical details that weren't addressed. Whats the self discharge of these caps? Sure, maybe they can hold a ton of energy in a small volume but who cares if it bleeds off in 2 hours? What's the…
Thats the discussion. In reality, you care about both. Power density to move the energy into and out of the cell quickly to shorten charge times and supply thirsty loads. Energy density to run lower loads for longer.
You don't need superconductors to get around the skin effect. It's actually interesting that you mention superconductors, as the skin depth in a perfect conductor is actually zero. (Anyone know what happens at DC in…
"Further increases are not recommended due to increased hysteresis loss." This is why I am REALLY hoping the materials revolution everyone keeps talking about takes off and we get some decent high frequency, high…
I can see the advantage, but I still would argue that just having some DC power standard like USB will always be more economical and practical than trying to build "do it all" supplies to work with all gear despite the…
Hey, not to shoot you down but there is definitely a transformer in the iphone supply. Second, building switching supplies that can supply an arbitrary output voltage/current isn't practical or economical. Third, don't…
