quote:Originally posted by realmswalkerIt would be beter to start at every one not wasting energy, turning off lights and such...

quote:Originally posted by Soul SurferThe most practical idea in this vein is the "do it yourself" commuter train. The passengers in a reasonably full commuter train could generate plenty of energy to drive the train along. This energy could be "harvested" by using pedals or possibly a lever pump to generate electricity to charge batteries to run the motors. This input energy could be monitored for each person and you would be charged for your journey based on the amount of energy you put into the system. Athletes might be able to manage a free ride! There would of course be a smallish fuel based generator in this hybrid fuel electric system to allow the train to get around when it had very few passengers in it.

quote:We create a world that needs more and more power to run it.
quote:We put high value the creation of wealth at the expense of being in balance with the planet we are on.
quote:We become so reliant on clever technology that consumes more that it creates. Now we are trapped in our own illusion that this is progress and that we are making a better world.
quote:i think you are cool all the same.
quote:Originally posted by VAlibrarianI do agree to the spirit if not the letter of "We create a world that needs more and more power to run it". Technically, we did not create this world at all. But we have created infrastructures that are highly reliant on intensive use of energy in the United States, and now that other nations are trying to follow our lead
quote: there is some question as to how to generate the energy required for this to happen. More nuclear? Drill deeper for oil? Burn so much coal that the sky will be filled with the smoke?
quote: It is possible to structure the systems on which we depend to use less energy, rather than let convenience and the marketplace drive everything we do.
quote: In the USA, we have many workers who drive two hours to work and two hours home, one person in a vehicle weighing 3000 lbs., which burns a gallon of gasoline every 15 miles. That is a lifestyle which our planet cannot support for every human. I do not envy these commuters, because they are wasting 4 hours of each workday in order to live in a home with an acre of grass around it.
quote:The original question about reclaiming wasted energy to do useful work reminds me of hybrid vehicles. Every time you step on the brake, you send electricity to a battery, instead of heating up your tires.
