  1. Piezoelectric Generator Team Akamon Huijun Park Hongmei Liu Yuki Yamagishi Shen Jiang (Andy)

  2. 2011 Tōhoku earthquake and tsunami What made it so difficult to save lives? Electricity supply stopped, then… > Medical equipments stopped 　　　　　⇒ couldn’t treat the patients… > Traffic lights didn’t work. 　　　　　⇒traffic accidents took people’s lives > Even if someone may be still alive, we were not able to know their locations

  3. So many power plants, then why!? Why couldn’t we transport electricity to those area? • Thermal Power Generation(61.7%) • Hydro Power Generation(8.1%) • Nuclear Power Generation(29.2%)

  4. etc... X X

  5. Localized Power Generation If the power plantsareseparated OR⇒ Then even one is attacked, no damage for others.

  6. Methods: Solar energy

  7. Low head hydro power Kankakee Low-Head Hydropower Facility in Illinois (1.2 megawatts installed capacity) Source: National Renewable Energy Laboratory(NREL)

  8. Wind power But what we are going to focus on is ...

  9. Piezoelectric generator

  10. Power-generating Floor (PGF)

  11. The theory of power generating floor -----Piezoelectric effect When pressured Pressured ion arrangement changes Electric energy *Picture on the right is from "Piezoelectricity",Wikipedia

  12. Application of the piezoelectriceffect igniting printer touchpad gyroscope clock speaker

  13. condenser Supplyenergy

  14. What're the merits? No fossil fuels required No waste No contamination Low cost No restraintof location

  15. Our project is…..

  16. How much energy can we get from this project? 1(J) of energy is produced when 60kg personmakes a 0.25m pace. On expressways of Tokyo Metropolis 1,100,000 of 2,000kg vehicles run 18km per day on average. If we introduce “energy generating floor” into expressways of Tokyo Metropolis … Energy production per day = (2000/60) * (18000/0.25) * 1100000 =2.6*1012(J/day)=720,000kWh

  17. Data: • Total length: 322.5km • Average daily traffic: 1,100,000 cars per day • Average driving distance: 18 km per vehicle • Average vehicle weight: 1345kg ( considering people and freight that vehicles carry, at least 2000kg should be used in these rough calculations) • Electricity output by PGF: 1Ws (60kg person steps on the floor in 1 second) • Size of one PGF: 30cm×60cm • Daily average electricity consumption per household in Tokyo: 10kWh • Amount of households in 23 districts of Tokyo: 4,322,539 (2010) So we can provide 1.5% electricity consumption merely by PGF under the expressways of Tokyo Metropolis. Data sources: pp.103-105, 12/15/2008, Nikkei Electrocis; 4/27/2011, Nikkei News; "Shuto Expressway", Wikipedia; Maebara Seiji, Minister of Land, Infrastructure, Transport and Tourism, during Q&A of publication of new expressway fare system; Annual report by Metropolitan expressway Co,. Ltd.

  18. What is more... "The efficiency of PGF has been increased by 30 times during the last 6 years (2005-2010). And it still has the capacity to increase at least 10 times." "The electricity produced by PGF underneath the expressways of Tokyo Metropolis will accound for 40% of the electricity consumption by households in 23 districts of Tokyo." ---according to President Hayami of Soundpower Corporation

  19. How can we use piezoelectric generation during the • emergency ---like earthquake? • Hospitals: large enough to supply electricity consumption of medical equipment, when only electricity is cut off during the emergency. • Traffic signals: still will work depending on the PEGF, because where there is a road, there is electricity (our motto ^^) • "Emergency Positioning System(EPS)": wired positioning system of PGF : wireless signal sending system: So, if you are out of iPhone's power, and looking forward to rescue corps, just find an intact road and jump!!!

  20. Constraint • Cost • Maintenance • Efficiency • Durability • Stability

  21. In a nutshell • power generation dispersion= risk dispersion • Save lives Where there is a road, there is electricity.

  22. Thanks for listening
