He has number-plate recognition software and greets you by name on your subsequent visits, with all your details available on screen before you can even off-load the junk. They video all sales and every transaction is logged. I wouldn't want to drive in there with a load of HW cylinders or a bundle of electrical cable that I couldn't validate. He pays good prices too. I was dropping off a dud HW cylinder (steel/ceramic) and copper and brass offcuts etc from our renovation and our street's recent inorganic :D An old steel washtub unit with stainless steel basin was collectively worth $20 (separated, they pay less if they can't weigh individual metal types). I reckon the Police should run some 'silent sting' operations, then they'd know which dealers to watch in future. As for this Do they even still use copper in power lines ?? Yes, the resistive losses in other metals are too high, and anything better is too expensive, being either exotic or limited supply such as silver or gold. Superconductors are exotic and incredibly expensive, but need cooling to extremely low tempratures, and even the so called 'high temperature' superconductors are still cooled to way below zero.
