Comment Re:Imprint is still allowed? (Score 1) 142

I haven't seen the desk-type imprint machine in ages. Must be 20 years, maybe 10 - 15 years in backwater areas.

Though the last time I got my car towed, the driver had some sort of miniature impression rig. Which still makes sense, if you're out of range of network and whatnot...

Also in Cuba, they had one down there. Which sorta makes sense too.

The $1 iphone charger I took apart was such a poor design and construction. Very little isolation, so unsafe. two transistor resonant style switching setup, cheapest there is. Too small output capacitors making the output very noisy. Though it claimed 1A, it was dropping out by 300mA. Not even close. No input filtering at all. no fuse. I'm surprised the things work at all, really.

That's not to say that it isn't possible to make a good charger for less than a .. whatever ripoff pricing apple charges, $30? There should be room to profit on a $5-10 charger, and meet all standards... But the $1 ones are absolute garbage, and no one should use them, ever.

Aluminium smelting uses a ridiculous amount of energy. So much that electricity costs can represent as much as half of the final value of a piece of aluminium metal.

It's also why smelters tend to be parked next to giant hydroelectric dams.

Note the process uses gigantic carbon electrodes and burns them up, releasing CO2; and cryolite as a flux, which makes fluoride waste products. So it's not entirely a closed deal. The aluminium part is, though. 100% reusable.
