We use the wind,the sun radiation and the bridge’s pylons height in order to store dynamic energy.We lift the “drops” using two ways: Wind energy(wind propeller under the bridge’s deck).The phenomenon of stack effect(air ducts under the tunnel’s floor which is water storage).The air velocity into the tube is strengthened by channelling hot water around the exit utmost of it.The hot water comes from solar energy reflectors.The above function ventilates the tunnel.The dynamic energy is converted into electricity by the controlled fall of the “drops” by the bridge’s pylons.Power produced due to gravity (30 pylons,100m height with 2drops of 10tn each):P1=n.ρ.g.h.q=730kw,E=730Kw x 4h=17.520KWh,covers the needs of 4415 people.To lift the “drops” we use the power of:
Wind: Pw=0,5.ρ.Α.ν³n=600KW
Sun:Pa=200KW
P=Pw+Pa=600+200=800KW
For the calculation of a possible budget,we must consider the benefits of new imported investments and the territory’s energy autonomy.
