[Elecraft] Battery vs Ultracapacitor

[Kevin Rock]

The articles I've been reading put these components in association with 
solar cells, regenerative braking, and with various types of fuel cells as 
the electricity source.  Fuel cells and ultracapacitors play very well 
together.  The economy of scale is coming from the hybrid automotive 
market.  Batteries are just too darn heavy for that venue.  Fuel cells and 
ultracapacitors complement one another very well for this market.  
Interesting times ahead.
