Solar Energy to Human Energy - no need of food

All the energy we have is indirectly coming from Sun.

(Solar Energy -> Plants -> Animals/Humans).

The energy generated from food in our body is chemical energy called Adenosine triphosphate (ATP).

I met employees of one startup company in New York that has filed a patent  to directly convert Solar Energy to ATP. The technology is in a very early stages and would be used as an alternative energy.

An extreme extrapolation of this technology would be that we may not need to eat food in future.

One Solution to 'Billion Passwords Stolen'

According to recent news reports, Russian hackers have stolen 1.2 Billion passwords
(http://money.cnn.com/2014/08/05/technology/security/russian-hackers-theft/).

Now, we are all wondering whose password has been stolen and how to protect it ?


If online email companies can display to the user the last time and location from where a person had logged in, every time the user logs in, it would alert the user.

Once the user gets alerted that somebody else had logged in from a different place and at a different time, he has a chance of changing his password.
