Not quite. Going from pure 2d, to 2.5d is not the same.
With 2d, you get (for example) 40000*40000.
To double (in the same chip area) - you need to go to 60000*60000, or 40000*40000*2.
You can do this several times.
You may reach 40000*40000*8 - you are not going to reach close to 40000, without the chip fabrication costs getting completely out of control.

In this case, as I understand it, bribery. Large amounts of money paid to corrupt malaysian government officials.
Dealing with the proceeds of this in the USA is not legal, and it is treated as simply as if the people involved walked into a bank and stole it.
The regulations - or earlier versions of them - were in force at the time of the original deposits into US institutions.

Not quite. The hardware is capable of energy recovery and in some circumstances may extend the battery life.
It's just that in most circumstances, for most users, it is going to be largely, or entirely reliant on battery to the point that it will work just fine for 5 years without any energy recovery.

If, for example you put it close - 50cm? to your phone or router, it may actively stay charged, and not discharge at all.

But, the battery is large enough, with low enough self discharge that it meets the published specs with none, and in at least many cases it's not going to recover anything meaningful.

'Large' in this case is a 450mAh lithium-ion battery (as shown in a teardown).
Properly chosen lithium ion do not suffer from self-discharge much.
This weighs about 15 grams. The battery will permenantly lose some capacity - but as the discharge is very slow and at very low rate, most of the capacity will be usable.

http://www.eevblog.com/forum/r... - I am unsure if this link will work. This shows a teardown of a tag.
On eevblog, under the title "weird "energy-harvesting" broadband (?) antenna ".

This shows a 450mAh rechargable lithium-ion battery.
http://www.ti.com/ww/en/wirele... - this is a TI device which is designed for sensor tags, and sports a 1 year battery life reporting once a second over BLE with a 2032 battey. This is one half the capacity of the lithium battery used.
It also won't be sending data at one second intervals.
It seems entirely reasonable that the comparatively large battery will last five years without any wifi charging at all.

Some more research finds that some instances of the blurb say it uses the RF to 'boost' the battery on the device.
In principle, the device is large enough that a $1 battery would run it for years. In some cases (if you put a phone on top of it) it will actually probably net charge. In a normal office environment, it will not.

However. In the USA, there may be reasons for wearing a gun - for example if you have the right carry permit and are simply confused as to what state/... you are in, or if you can wear it in the airport.
In the UK, merely carrying an imitation weapon, never mind a real one, is illegal. (in some cases, carrying a rifle or shotgun may be legal).
This rather changes things.

'What we know is that the vehicle was on a divided highway with Autopilot engaged when a tractor trailer drove across the highway perpendicular to the Model S. Neither Autopilot nor the driver noticed the white side of the tractor trailer against a brightly lit sky, so the brake was not applied. '
