Great show on making Mac trucks using platinum and copper.

I hand a little surgery and am laid up and bed and watched this show and part of it was the history of platinum. You can see that platinum will always be in need.

More on the from the website--

The highway truck — a modern workhorse, a heavy hauler vital to commerce — carries an 80,000-pound payload and must operate in every condition from sub-zero cold to triple-digit heat. To survive, it must be strong, durable and fuel-efficient, like the Mack Pinnacle, an engineering achievement made possible by platinum, petroleum, copper, manganese and polyurethane.
