Re: World's Largest Conveyor Belt

Mark eloquently commented in misc.writing:

Did you know that if you leave a light on for one
hour, you have just burned 10 lbs. of coal?

Errr?
Coal has a heating value of about 3,645 watt-hours/pound. That
means a typical 100 watt light bulb should burn about one hour per day
for an entire year on 10 pounds of coal.
