    I AM an engineer, though a software engineer not an EE. Nonetheless, you might want to take a look a this, the link is included in the diary but here it is directly.

    A regime is at it's most dangerous when it believes it's own propaganda...but that is also when it is most vulnerable.

      "Based on these claims, a five-minute charge should give the capacitor sufficient energy to drive a small car 300 miles (480 km). However, standard household wiring is not capable of delivering the power required for this, so charging times this short would probably require purpose-built high capacity dispensing stations.[3] Overnight charging at home should still be practical[4], as is using a second EESU for the home which could be charged overnight using cheap, off-peak electricity to then charge the EEStor unit in the car in 5-10 minutes on demand.[5]"

      In other words, no five minute charges on your home circuit.

      The good thing about EEStor is that it at least seems capable of storing enough power to operate a practical car.  But charging remains an ugly problem.

      •  Yeah, in re-reading it (0+ / 0-)

        it looks like you need a 3900 volt circuit to get the 5 minute charge time. The 220 circuit could not possibly achieve this.

      I'm a software engineer too, with a moderate electrical background.  But math is math, physics is physics, and I could have answered these questions in high school.  Seriously, check your numbers before making claims.
