Speaking of batteries ...

... The consumer electronics industry needs a better commodity-rechargeable-battery technology.  Purely aside from the issue of charge life, come on, people, is it really any surprise to anyone that many devices designed to operate on 1.5v manganese-alkaline¹ primary cells don't work well (or, sometimes, don't work at all) when you replace them with 1.2v NiCd or NiMH cells?²

[1]  Or lithium-iron, or silver oxide ... pretty much all the commodity primary-cell technologies in common use run somewhere in the 1.5v-1.6v range.

[2]  I'm seeing some references to a titanium, titanium-lithium, or titanium-NiMH rechargeable battery that's a true 1.5v primary-cell replacement.  However, I can't find any definitive technical information, just marketing claims that don't specify things like internal resistance or discharge rate.

Yeah, there's a lot of very intensive work being done on supercapacitors.
