What does concern me is our general trade deficit ....
Garth, two words: Energy Conservation.

A major push to bring down the cost of LED lightbulbs would yield
gigantic energy benefits. Did you know that barely 5% of the BTU's

The rest is lost in fuel extraction, processing, transportation,
generation, waste recovery, and power transmission.

Coal is of course carried in steam era hopper cars...
