Green elevator will popularize in 4 years time

Every lift will generate the electricity by itself in the coming future. The experts predicted such lift with energy regeneration technology may completely replace the non-energy regeneration lift in 2-4 years.
The technician from HITACHI JAPAN explained the theory of this energy recycle lift. When the lift goes up or down, it will need the brake to keep the constant speed. At the same time, lots of mechanical energy converts to electric energy by electrical machine and uses up in the heat resistance. By using the Power Return Device, we can connect the wasteful electric energy to the power line and achieve the purpose of power recycle using. The conversion efficiency can get over 80%.
Now the elevator energy saving technology is developing rapidly, and “energy regeneration” is just one of them.
