  15. 15. The way that we can weave these realities and aspirations together and turn them into opportunities and rewards is through piezoelectricity. Piezoelectric tiles can be placed underneath the top layer of asphalt on select parts of 35W in Duluth, which is up for repaving in 2015. The top layer of the asphalt has visco-elasto-plastic qualities which make it flexible. The vehicles that pass over the tiles create compression stress. The compression stress deflects vertically and releases mechanical energy. The piezoelectric elements, in the form of tiles, captures the mechanical energy charges and converts them into electricity which can be used immediately, stored, or sent back to the grid. Because the piezoelectric tiles are underneath a layer of asphalt, the road can be maintained the same as it would be if there weren’t any tiles. The road can be plowed and swept the same way, and the tiles themselves do not require any maintenance beyond routine system checks. The life span of the tiles is approximately 30 years, and the installation of the tiles does not change the characteristics or load reaction of the asphalt. This does not affect a car’s MPG. There are currently five countries that we have found to have installed piezoelectric systems. Anything from a rail line in Israel, to tiles in the train station in Tokyo, underneath portions of the Veneto-Trieste highway in Italy, to underneath dance floors in England and the Netherlands. Well, why not Duluth? Installation of the piezo tiles underneath 35W would make Duluth the first city in the US and in the western hemisphere to capitalize on this technology. This installation could not only put Duluth on the map, but directly affect the mayor’s 90 by 20 goal. We are proposing that piezo tiles be installed along the points of 35W that run through Duluth and are on the ground. This way, integrity of overpasses and bridges will not be compromised and this will also allow more energy to be created by any snow or rain that runs down the hillside and sits on the piezo tiles. The cost of installation after grant money allocation would be approximately $1.8 million. This is what Duluth would be responsible for. This is only 27.5% of what the total cost would be if it all ten miles of the road that runs through Duluth would be repaved. The six miles of 35 that we are proposing to be lined with these tiles would produce over 22 million kilowatt hours in one year. That is 2 million more kwh than the city of Duluth operations buildings used in 2010. As stated before, the energy produced from piezo materials can be used immediately, stored, or sent back to the grid. When being sold back to the grid, the energy company pays the holder of the kilowatts mony in the form of feed in tariffs. Feed in tariffs provide guaranteed grid access for the energy producer, long term contracts for the electricity produced and the purchase price is based on the cost of generation. The current going rate for feed in tariffs is 8.734 cents per kilowatt hour. That means that the city of Duluth could make $1.9 million on the energy produced in just one year.
  16. 16. An asphalt road has visco-elasto- plastic qualities which make it flexible. Compression stress from vehicles passing over the asphalt causes it to deflect vertically, releasing mechanical energy. Piezoelectic tiles capture these charges and convert them into electricity which can be used immediately, stored, or sent back into the grid.

  30. 30. ThemoneymadefromthepiezotileinstallationwouldhelptoreduceDuluth’sresidentialcarbonfootprintandenergyuseasthepopulationisprojected to increase. We propose that three funds are generated and each year would receive a specific amount of money from feed in tariffs. The first fund would be controlled by the city and would be used to install piezotechnology on various other infrastructures, such as sea walls, interior streets, and rail lines. The cycle of these installations could run parallel to other infrastructure projects happening in the city. For example, rail lines around the new multi modal transit hub in downtown could be outfitted with the energy harnessing technology and any energy produced could either be used to power the hub or the feed in tariffs could be used to help pay for the new hub. The second fund would be used to provide money to retro fit homes so that they are more energy efficient. This fund would extend and expand the currentDuluth’sEnergyEfficiencyProgram(DEEP)byofferingalarger“menu“ofitemsforresidentsupgradingtheirhomes.

  33. 33. Neighborhood Fund The third fund would be dedicated to neighborhoods and used to upgrade infrastructure. The upgrades would incorporate piezotechnology installations to produce energy and money for the neighborhood. We started looking at five specific neighborhoods within Duluth; all have comprehensive plans, active communities, and common goals. These neighborhoods are Morgan Park, West Duluth, Lincoln Park and the combined Central and East Hillside communities. Morgan Park provided us with an opportunitiy to show how this technology can mark the future developments for the community. The technology would be in the form of poles that bend in the wind or when covered with snow, which create compression on piezotiles to produce energy.
