Look Ma, no batteries

The electric car of the future may well not have batteries but instead a super-duper ultra version of the humble capacitor. Austin Texas based EEStor has patented ''technologies for replacement of electrochemical batteries,'' meaning a motorist could plug in a car for five minutes and drive 500 miles...without gasoline.

In the vacuum tube audio world I frequent, people argue about the sound of different types of capacitors (which tends to drive engineers crazy). Hmmm...... I wonder what one of these babies would do in my homemade amp.

We'll probably never know because GM will buy the technology and bury it, right?
