I thought this was hilarious, but also an excellent commentary on what digital storage has enabled us to retain over old school paper. Yet, somehow, the experience of reading information from paper over screen is different. I consistently feel that I retain information better when I've read it on paper.

New wireless devices need no power supply, can harvest energy from TV towers

Wireless devices and sensors capable of sending and receiving data may soon be able to also harvest the power they need, right from the air, thanks to the radio waves that already emanate from cellphone and TV towers.

The team at UW has developed a technique they call "ambient backscatter", which can let devices use the cellular and TV transmissions already being broadcast around us, reflecting those signals to send and receive their own data to similar devices, without the need for a battery or other power source.

To test the ambient backscatter technology, the researchers set up a small testing network in Seattle, and the devices were able to communicate with each other, as sensors would in a real-world application, even up to 6.5 miles away from a TV tower.

Hope this post is fresh ! Let me know if it is not :)

Tesla knew about this stuff way back when. His tech needs to catch on. He invented radio, not Marconi, and back when Marconi used 19 of his patents to get across a static-ey S sound on the radio, Tesla was using different frequencies for each control on a remote that made a RC battleship destroy another model boat. The man made ball lightning in a lab. He made a Tesla coil with the exact frequency to stop all electricity in its tracks like in The Day The Earth Stood Still. All over a hundred years before that movie came out.

Half of all research papers published in 2011 are now already free to read, according to a report funded by the European Union. The report suggests many more research papers are openly available online than was previously thought, and the number is set to rise rapidly. The report's authors call the 50% figure for 2011 a “tipping point”.
