Tons of gravity energy going to waste
« on: March 12, 2007, 03:49:19 PM »
There are thousands of cars and trucks intering and leaving citys almost 24/7 daily.
Now that's alot of iron. (Weight)

Imagine a compressor system installed in all lanes of the hi-ways leading in and out of major citys that compressed air to holding tanks to be used to turn a turbin to generate electricity for the whole city.

It's about as close to being free energy, as anything because the traffic is gonna be there anyway

Could be designed similer to a truck scales and when an axle crosses it, Wa-LA instant compressed air!!!

If any of you people become mayor, you might propose this idea to the city, then give yourself a raise.  ;)

Would like any and all feed-back on this half baked idea.

The energy from a system like this is not free.  Every vehicle compressing air must expend extra energy.

Not nesassarly. If it was built on any slight slope incomming, it wouldn't require any extra energy.
Also the platform (for lack of words) would only move a short distance down. Like maybe an inch or so. Thanks for the feedback.

An idea exactly as you are proposing was already featured on a freeenergynews.com article a couple months ago.

How about magnetic mats or just a row of magnets in a plastic protective covering on the underside or in the bumper area of vehicles and coils in the road in the places where lighting is needed. Store collected energy by day in batterys and use it at night to light signs and streetlights. bumper to bumper traffic for hours in the morning and evening would seemingly genorate a hell of a lot of electricity. And the flux drag wouldnt mean much to an automobil or heavy truck. That one has been a thought of mine since i was a kid. What do you guys think? Just an idea.. Always seemed plausible to me.

Sounds just as good as any. Don't see why it wouldn't work.

I don't follow freeenergynews so I missed the article. But good to know someone is thinkin.

Ok Dave.
Hows about linear turbines along the side of the road. Hook these to genorators. Use the wind produced by a passing auto to drive the turbile or a series of turbines constructed much like heatvents on the roof of a building. Or a squarl cage fan hooked mechanically in series. Maybe gather enough tork to power a 5000 watt genny to charge batterys. The wind is truley a byproduct and of no use at all. In this way it is a passive system and has no more drag than normal travel on any vehicle. And a windy day would be a bonus.  Hey this is fun!... Next idea please!    Moab.

Hi Folks,

I think alternative energy sources should be fully enviroment-friendly.
The ideas you introduce are interesting but the energy they would create are based on sources that not enviroment-friendly at all.

Somewhere I read an interesting approach to use wind energy: in a highly mountain area a natural cave was found to be oriented almost North-South direction and the ruling wind direction was from the North. An opening was made at the South side of a longer/more or less straight section of this cave and a generator was fixed in the South opening, wind could come in from the North entrance.  And the big draft turned the wheels of the generator almost all the time.  Unfortunately I cannot remember where this was built or if it still in operation.

Thank-You Gyula.

Dave's idea uses weight and momentum to compress air. then to power turbins.

I think the point of the thread was to try and squeez that little bit of energy that that is being waisted by autos and trucks. As i said the wind idea causes the auto to do no more work than it would normaly do to move it down the road.(passive) and if we could capture it it wouldnt be free. it would be makeing use of somthing (Wind or weight) to do work that was otherwise waisted. Kind of a fun thing to ponder.

Exactly.  You explained it better than I could. It's wasted energy that could be utilized because the weight is going to be there anyway.

I'm not disagreeing with Gyula but as you said, as long as the energy is there take advantage of it.  It is interesting tossing this around and I like the responses. I'm sure there's probably alot of things we haven't thought of yet.
