But these are figure that don't count the oil used to grow, transport, and cook the food that is used to power the person that is doing the riding. A totally stupid analysis. No, what you wrote qualifies as silly. Those figures are a constant for both the cyclist and the non-cyclist, since both eat and the food comes from these same sources. The non-cyclist typically consumes more calories than the cyclist because cycling improves the effiency of the human engine and reudces the number of heartbeats per minute, further reducing the number of calories. While amount of additional food required to feed a fit cyclist who trains for racing may well be significant, the commute cyclist does not need any additional food than his sedentary counterpart and may well consume less. Its like those idiot that call electric cars zero pollution because they don't know where the energry came from. Just for food processing we get "All together the food-processing industry in the United States uses about ten calories of fossil-fuel energy for every calorie of food energy it produces." In those cases, you are correct. There is no non-polluting form of transport, though some are clearly less polluting and more efficient than others. If you use, say, hydroelectric or geothermal plants, pollution is still a huge concern (as is the localized environmantal damage), but the overall air quality would clearly improve. ....stuff deleted |

When I used to ride a road bike, getting airborne was a great way to bend the wheels. Then your cycling skills left something to be desired. Bunny hopping is a very useful skill for avoiding obstacles in the road: speed bumps, tree branches, broken bottles, fallen cyclists. And no, it doesn't bend wheels when done correctly. -- terry morse Palo Alto, CA http://bike.terrymorse.com/ |

That was a minor irritation to the owner - so he drove them very slowly. But that car does perfectly fine on the standard speed humps on the residential streets. Lots of cars like that scrape bottom when pulling into gas stations, parking lots and driveways. I know that there are cars that can't get into underground lots. You see the scrapes at many sorts of different places than speed humps. I guess they don't complain about those. You guess wrong; all are examples of sloppy and/or substandard construction. Bad curb cuts and incorrectly sloped ramps are just as bad as speed bumps... nate -- replace "fly" with "com" to reply. http://home.comcast.net/~njnagel |
