Using dummy numbers. But, lets say you need to be going 100mph to escape the suns gravity. The Earth is moving around the sun at 75mph. So you only need to speed up 25mph to leave.
But to fall to the sun, you need to slow down 75mph. And speeding up and slowing down in space take the same amount of energy.
Maintaining a supply of spare parts for a line of notebooks could very well use more natural resources than maintaining a supply of working laptops for replacement.
Your logic works if you only are going to listen to a song a few times, but after a certain threshold, the artist would receive more money than from a CD or iTunes purchase.
I don't think there is anything wrong with an email provider asking me for my cell number to send me text messages, how else would they send them?
In addition, a cell phone number is NOT required to create a Google account. Sure they ask (and gender is apparently required, I just made an account), but if you leave it blank, they won't complain.
Would you care to elaborate how you'll be able to power a drone for an extended amount of time? I was doing some minor research (I was curious about the pirate bays 'server drone' idea), and the best that I could personally come up with was flight times of about an hour. That doesn't seem all that useful to maintain a constant server, or traffic cam, presence.
