And I quote: "Ultracapacitors have replaced or are being tested to replace batteries in engine starting applications such as . . . submarine engines . . ."

No hydrogen emissions, no chemistry at all, no heat emissions, no seawater/battery acid danger (chlorine gas), millions of duty cycles (not ~ 700 as with lead acid), one tenth the weight of lead acid batts, equivalent of an 800 km. drive for ~$10 (CDN) . . .
