Many people watching their weight, but it is sometimes difficult to work out or monitor the amount of calories in foods,not to gain overweight. The concept of energy-efficient elevators ½ offers an alternative solution where the elevator stops between floors. This not only reduces power consumption by reducing the number of stops, but also causes people to ascend or descend the stairs to get to the workplace. For example,if you want to use the elevator to reach 2nd floor and someone else wants to reach the 3rd floor, the Eco-Life ½ Lift will stop at 2 ½ floors. Very unexpected, but a very interesting concept!
