For me this is a case of environmentalism gone overboard which tends to happen often. This would only be feasible for downhill sections where cars coast or brake…
Even then the cost/output ratio would be silly…

I’d rather just forget about the thing alltogether and invest the money in geothermal…

The path is one way or two… ??
I think it only for th one way because if it will bw two way then the continuous passing of car in a random way will reduces the surrounding wind velocity….

Adding rollers just before the toll booths at the end of the bridges or a slight incline that the cars would drive on thereby depressing hydraulic pistons would work-they are rolling to a crawl or stop anyway-use their weight!

Vote them out of office. There are many small towns in the upper midwest whose governing bodies have embraced all sorts of ‘green’ initiatives through ordinance and law changes. The best thing about most of these local governments is that they do not fund these initiatives with taxpayer dollars. Thus, they are doing what government is supposed to do, allow individual initiative while finding a balance for all citizens and not increasing the already heavy tax burden on the citizens. Now if we could only stop the runaway, reckless spending that our current administration seems bent on.

1. an instrument that change sound energy to electrical energy(may be from moving body)
2. from twisting thing to mean that by some special mixing we produce material in thin form and then we fabricate inserting inside on close on the tree freely then when a person moves the cloth bend a little and that special material bend together this time there is production of electricity the same is true for tree which the material is attached below the most sensitive part for the wind

Your thought is exactly the concept behind the Solar Roadways (www.solarroadways.com). Mr. Scott Brusaw, the founder proposes to cover the road surface with special solar panels that can be driven over.Though it is a costly proposal, a test track is under way with a grant from the US Department of Transport.

There is also another more cost effective proposal to bury water pipes under the road surface and use the steam generated to produce power. A notable development in this area is the experiment by Worcester Polytechnic Institute US (www.ecogeek.org/component/content/article/2014).The downside of this proposal is that it requires a lot of water and steam turbines by the roadside or underground.

Regarding harnessing the mechanical energy from the superimposed load of the traffic,there have been some experiments by an Israeli piezoelectric company Innowattech (www.innowattech.co.il/solutions.aspx). Here again the commercial viability has to be proven as the power out put of piezoelectric materials is not that encouraging. They are also very expensive.

So what we need is a combined approach which can harness both the heat and load on the roads in a single system. This needs further R&D. Such a system would pave the way towards the smart intelligent roadways of the future.

1.energy due to friction (when it stop and when it travels)
2.energy due to the vibration of a car up and dawn

so with this method we can get lots of energy from the road and even there is another way beside this just focus on the road

A result of aerodynamic loss is the movement of air surrounding the vehicle. To me, it sounds like this bridge idea intends on recovering some of the aerodynamic losses of vehicles in the vicinity of the bridge. By adding components (i.e. rotating panels, etc.) to the bridge will not affect the aerodynamics of the vehicles themselves nor the air the vehicles are moving through.

I’m not saying that my thinking is necessarily accurate but that is my current understanding of it. If you care to provide better reasoning to why you believe otherwise, I’d like to hear it.

Good on you for opening your minds and developing this potentially great solution from such a unique and intelligent concept.

The intent is there… lets hope it passes the practicality test too!

Have your say in COP15 when world leaders gather to draft a new global climate treaty this December!

This concept will work better in wind screens and rooftop screens in individual buildings where it is easier to maintain.

another great idea by very creative individuals. The two biggest issues facing us today with respect to “renewable energy conversion” devices is:

1) Local Governmental individuals, Mostly at the small rural town level. A great Majority of these folks move into small rural towns for a variety of reasons. Like most other folks, they want piece and quiet. However, a lot of these folks are Professionals from all walks of life that are ignorant to technological change. They have money, but in a lot of cases, no desire to truly help the environment by allowing old “ordinances” to be changed to adapt to new technologies. Additionally: it boils down to “NIMBY’S”. My wife and I would like to install a medium sized wind turbine on our own land. We meet or exceed all the installation requirements, however, the towns in NH have a ordinance that won’t allow “any” structure over 30 feet tall without “special exception” from the Zoning and planning boards where these Ignorant people sit and control. This ordinance is from the early 1900’s where fire fighting equipment couldn’t pump water more than 30 feet high. Now that has been far exceeded in every small town in America. Even if the towns fire fighting equipment is “older”, it would have to be from the early 1800’s not to be able to pump water over 30 feet high.

What does pumping water have to do with Wind turbines anyway–In most cases, you DON’T use water on electrical fires anyway.

The other issue, which is still part of the NIMBY ISSUE, only, now it’s alot of “investment” people that have POLITICAL INTERESTS that get money from large contributors like, oil companies.

THESE politically TIED people are both lying and being lied to by big companies and the large government interests. THE “ever lasting green back will put our country into a energy slump that we’ll never see out of the dark again” because small to medium town political interests are unwilling to gain “future” independants from fossil fuels as well as nuclear, When our political leaders stop lying and truly start working for the American People again, our country will raise itself from the depths of energy starvation as well as being able to give the American work force a chance to work again.

We need to stop sending our newly developed technologies and jobs overseas where they are exploited.
American’s and politicians alike need to re-evaluate our issues and start working for Number 1 again!!

Fossil fuels are dead, stop trying to stretch what is no longer in the ground and get the technologies moving faster. That also means, changing local leaders so the ordinances can be updated to keep pace with technologies. Without updating ordinances, what is the point of creating new technological advances if the “leaders” are going to keep them down by Staying in yesteryear.

I would like to have anyone with similar views email me to discuss and exchange information on how we can start to get real change moving ahead without using the same old strategy of “empty promises”.

Thanks for your interest and any comments
