Motion Electrons Microcosmos
Terahertz electronics is really exciting. This is the similar technology to what they use in the new airport security checks to find weapons (The so called body-scanners). It has many purposes, but because it can go through more materials and reach longer distances it has the potential to make better wireless devices. We might could have free wifi everywhere and never need a data plan again. Remote parts of the world would finally have access to the internet. It would be much harder for China and other closed governments to block access. This would also be able to transmit data faster as it has a shorter wavelength so it is easier to modulate data. Hopefully this stuff can come to fruition soon.
