dr ehab said that piezo electric cell is very expensive as the cell in the lab costs 1000 L.E so if we will make acarpet by it will cost min. 5000 L.E , he said also thats areal project and in Europe they make shoes by that idea and make it wireless (i cant understand how sunny ) - i went to the faculty today earlier - i asked him also about green house idea he said that ch4 hiph poisonous and any leakage must cause danger risk so it afailed idea , also asked him about flywheel idea , he couldnt reply but he said that it is avery nice idea and go on ( my opinion that flywheel idea is the best one.)
