Good job bringing this to light. People won't realise how huge the problem is and municipalities are woefully ill equipped to...
Agreed; mining can never be sustainable, but then how do you get the metals to make all the things you need in the course of...
Very good piece.
Alchemists have succeeded in fashioning the high-tech version of the Philosopher's Stone: they can now make diamond films out of soot and a gas named argon. Chemist Dieter M Gruen's magic recipe: flash light on a mixture of pure soot -- buckyballs, which contain 60 carbon atoms arranged in a hollow sphere -- and argon gas, and the liberated carbon atoms deposit and form a thin diamond film.
Dieter believes that the new technology can produce diamond films 2 to 4 times faster than conventional methods and at half the cost. Low production costs could make the use of these tough films -- mainly used in machine tools -- more common and affordable.
