Re: [EVGRAY] Lithium Ion Capacitors?

Hi Bob,
These guys have ...driving  a forklift.

Though these are actually supercapacitors where energy is stored
capacitively not chemically.
These non polluting environmentally friendly capacitors have 40 year
lifespan and 1 million charge recharge cycles.

The capacitor unit in the video is 3.5 KWh and sells for $4500 AUD down
here in Australia.
Construction/manufacture is said to be pretty shoddy (made in the Middle
East) somewhere.
It's early days yet with the technology but sure looks promising.
