There is a time and place for everything. Yes, every improvement in the human condition has come at the cost of increased energy consumption. So-called "green" energy is about providing the same energy or even more than fossils can provide in a way that will be sustainable, mitigating the known harmful effects of littering waste everywhere. There is no debate here that falls under the umbrella of weight-weenieism. How this relates to the thread topic of titanium spoons, hydrogen tires and bikes made of 5mph bumpers is dubious at best.

There is a lotta foo to go 'round for light-hearted chit-chat about nonbicycle topics.

Just sayin'--
Carry on.
