How much coffee do you drink? How much caffeine?

Caffeine content of coffee is not a standard unit. Variables include:
• instant generally contains less caffeine than fresh
• type of coffee bean
• grinding
• how the coffee was made e.g. filter verses percolated
• where it was made

Where it was made? In 2005, a university study measured the caffeine content of 97 short blacks from restaurants on the Gold Coast, Queensland, Australia. The strongest sample contained nearly nine times as much caffeine as the weakest.

Waste heat can be recovered as relatively green energy

“Pollution is nothing but the resources we are not harvesting. We allow them to disperse because we've been ignorant of their value.” — R. Buckminster Fuller — http://www.brainyquote.com/quotes/quotes/r/rbuckmins101926.html

Not normally considered a “pollutant”, but data centres spend a great deal of money on infrastructure, energy & other running costs to remove the heat produced by servers. In accordance with the advice of Buckminster Fuller, above, heat in data centres is coming to be seen as a resource:

A startup in the Netherlands has plans to move servers to homes for heating:

Poultry & pig farmers can reduce energy bills by 65% by capturing waste heat:

Dumbing down Australia — the view from Bloomberg

“Having this reliance on the bottom end of the economy, like small businesses, is a short-term fix,” said Andrew Hughes, a lecturer at the College of Business and Economics at Australian National University. “Cutting back on research is insanity.”
