Comment Re:Ways around this (Score 1) 512

Well, most (if not all) Android phones by default (since Marshmallow, I believe) default to using any USB connection plugged in for charging only, and requiring you to unlock the phone to change that option each time. And before that (since at least Jellybean, I believe) don't expose filesystem data until the device is unlocked. So that gets you some modicum of safety. And with the device encryption turned on, it won't even get into the OS without an unlock code. So provided they're not going to physically dismantle the phone, or other such destructive measures, your data is pretty safe. Apple... well... not so much.

Of course, whether the courier "loses" the package en route is another matter entirely.

Comment Re:Wind and Solar are Environmental Disasters (Score 4, Informative) 502

It's not "Countless". Wind turbines kill between 214,000 and 368,000 birds annually - a small fraction compared with the estimated 6.8 million fatalities from collisions with cell and radio towers and the 1.4 billion to 3.7 billion deaths from cats. So if it's really migratory birds you're so worried about, you'd better ditch your cellphone. And/or kill your cat.

I know my parents' bank in the UK doesn't allow you (technically, I believe you still can, but it's discouraged) to use the numbers on the card to make online purchases. They provide an application that runs on your desktop, connected to the internet, that generates a unique credit card/CCV/expiry number for each session (I believe it technically has access to a not insignificant pool of numbers at the bank, so there is the possibility of re-use but only after a very large number of session requests has taken place), so even if the details are stolen (which is unlikely) or the merchant is malicious, the transactions can be isolated and reversed very easily.

Comment Re:Energy in? (Score 2) 158

So they have to procure an amine in the pure form,


mix it with purified water,

Right again

heat it to 125 to 165 oC (a lot of energy, also under pressure),

Partially Correct - there was no mention of it being under pressure.

bubble the air through it (requiring at least the same pressure as the solution so there wouldn't be backflow)

1.001 Atmosphere of pressure, yes.

then recover the product using distillation (energy intensive).

Correct. Though as the solution was originally at 125-165C, the methanol would most likely be in vapour form, so condensation would be a relatively simple matter.

It's good chemistry and interesting catalysis, but I don't see how it will be cost-effective.

My guess is it would be cheaper to let a tree reduce the CO2, chop it down, and make the wood alcohol from that.

Oh, of course. Though that is a process that requires considerably more time than this one, it seems.
