Today we introduce a new green and enjoyable alternative to
today’s elevators – Yesterday’s elevators!
travel fast and smoothly between floors with out electricity or even wires.
How does it work?
A confined space (a square frame) is aligned to the building (in our out).
A Square hot air ballon is then placed inside that space.
To go up , we warm up the balloon, causing it to elevate .
To go down, we lower the heat level.
Enjoy the ride.
