Invention of the Day

A vertical treadmill for indoor climbers.

It only has to be about 15 feet high with no need for ropes since the drop to mats is OK from that height – it’s used for bouldering.

Each vertically treadmill could have fixed hand and foot grips, or better still these could be electrically actuated to simulate a long wall with dial-up degrees of climbing hardness.

Mechanisms for electrically actuated grips popping in and out of the treadmill wouldn’t be hard to figure out.

Then every air conditioned gym could have an indoor climbing section and the things wouldn’t be so bloody crowded and hot.
