I HAVE an idea whereby high-rise buildings can produce energy and satisfy their own energy requirements.
In a high-rise building with many super-fast lifts, the air in the lift wells could be harnessed to generate electricity.
When the lifts move up and down in narrow lift wells, it pushes air forward.
| the top and bottom of the lift wells.
The air can be used to propel light-weight turbine fans, which can generate electricity.
This technology is relatively simple.
With all the high-speed lifts going up and down in high-rise buildings, there will be a constant supply of air power to tap into and convert into energy.
It would be a cheap but precious source of power for the owners of the building, and can supplement the electricity supply needed to light up various areas in the building I hope the authorities and polytechnics could consider my suggestion and test out the idea.
