Solar & Wind Bridge Could Power 15,000 Homes

Italian designers Francesco Colarossi, Giovanna Saracino and Luisa Saracino created a “Solar Wind” bridge concept for a Solar Park Works Ė Solar Highway competition in Italy. The competition called for designers to imagine new ways to reuse a decommissioned elevated highway, while incorporating renewable energy sources. For their creative concepts, the designers won second place in the competition, with an award of 7,500 Euros. First prize was 20,000.

In the proposed design, 26 wind turbines would be used in the understructure of the bridge. They would catch wind currents moving up the gorge and generate electricity. The road surface on the bridge would incorporate solar panels. According to the designers, the energy created by the wind and solar elements of the bridge could power 15,000 homes.

The bridge surface would also contain a green promenade where drivers could stop and enjoy the views. Additionally there would be soil beds for growing vegetables and fruits on the bridge, so visitors could purchase food. Though adding soil beds seems like it could create a lot of extra weight to the bridge, combined with many visitors which might decrease its lifespan. Also, would the emissions from vehicles crossing the bridge wind up in the produce grown on it?

Adding wind turbines makes sense because of the natural wind currents in a gorge, as does adding solar because of the large surface area. One might argue that adding the circular frames around the wind turbines with the rotating blades adds an aesthetic element to the bridge. Using clean technology in a bridge might help to promote the idea, since bridges are so often focal points. Initially it would probably generate a lot of press, and perhaps discussion when in use. Disadvantages of using a large number of wind turbines integrated into a bridge are the number of birds that might be killed by them, and potential damage caused by turbine vibration.

Wonderful the thought of being creative and useful, and not hurtful to the earth, and the people and all that lives on earth.

Personally I have no problem with the more traditional wind powered turbine, quite a few where I live in the relatively flat East Coast of England, more to come. This design is so much more attractive for more urbane environments; whatever can be done to reduce our dependance on an energy source created 1000s of years ago is surely a good thing - not so great for those countries who are oil exporters though!!

P.2- you get more $ non out of court settlement too!

Re:Wind power generation-Newer types of both generators & the blades for them,make generating high amounts of energy from 20mpr or less wind current reality-see

Just place screen across the already in place ciralces around the fans=no hurt bird/other.
It listed abandoned,then says cars using it,but no reaon positive reason why this has not already been strongly implemented as it should now be.

Food should be growen some distance away to prevent the smog collection,but could also be growen on higher level teirs to not get the smog which is mostly heavery than air,so filters downward.

This "contest"was not nessary& maybe a "cover"-as they have already knowen of this idea for years,but have not done it& perhaps now might be about to.
Ex:Using brakes on your car to generate elelctricity when you put on the brakes,to re power your batteries-it's knowen,but not widely,nor used much-DEMAND IT-safer&less gov or other source dependant upon others=off shelf tec.
Utilites paying you for your electric co-generation was by the force of a court case,they did not want to pay,& now do not want to allow you to co-generate or over charge you for the req. intertie req.'ed for safety,which again,a court case has ruled illegal,not to charge,but to over charge& they must allow-but they still fight it& you,to get you a possable net loss to you,even though they know ahead of time they will lose case,but charge you by making you sue for your Rights Enforcement-still worth it-BUT-do NOT Settle out of court,or others can not use your case nor can you,againest co.proving history of abuse of law. You get more not se
