Coal to start a download

In a brief video Jay Walker ( at around minute 7 of 8 ) shows that a single MB of data needs the energy of a piece of coal just to find its way from a server to your computer. 5% of all energy we consume is being needed to run the Internet ( may be compared to yearly amount of cerosin needed for airplains ).

Super Brain: Too expensive and too unefficient

Got 208 Millions of USD left? Buy yourself a second brain. World`s fastest computer is fairly as capable as your own head. But there is one downside.

There might be one upside, however: It will never complain about headache (Not meaning to have sex with it…nooooo).
