Amazing 1700ft transmission tower climb!

This is a first-person, POV video of an electrician climbing to the top of a 1768-foot broadcast transmission tower.

Amazingly, the climber doesn't have a harness, though occasionally he clamps himself onto any odd piece of the tower that will hold him. Doesn't look like he has a parachute attached to his back either. No wonder this is one of the most dangerous jobs in the United States.

French tire company Michelin new invention: The Tweel

The 'Twee'l is an experimental tire design developed by the French tire company Michelin. The tire uses no air, and therefore cannot burst or become flat. Instead, the Tweel's hub connects to flexible polyurethane spokes which are used to support an outer rim and assume the shock-absorbing role of a traditional tire's pneumatic properties.

The Tweel consists of a cable-reinforced band of conventional tire rubber with molded tread, a shear band just below the tread that creates a compliant contact patch, and a series of energy-absorbing polyurethane spokes. The rectangular spokes can be designed to have a range of stiffnesses, so engineers can control how the Tweel handles loads. The inner hub contains a matrix of deformable plastic structures that flex under load and return to their original shape.
