I think science is great. I really do. But just as I wonder about the people who develop computer viruses and things like that, I have to wonder about scientists who pursue work like this.

This year, 2007, has also brought the news that terahertz lasers small enough to incorporate into portable devices had been developed.

Sandia National Laboratories in the US in collaboration with MIT have produced a transmitter-receiver (transceiver) that enables a number of applications. In addition to scanning for explosives, we may also assume their integration into hand-held communication systems. ‘These semiconductor devices have output powers which previously could only be obtained by molecular gas lasers occupying cubic meters and weighing more than 100kg, or free electron lasers weighing tons and occupying buildings.’ As far back as 1996 the US Air Force Scientific Advisory Board predicted that the development of electromagnetic energy sources would ‘open the door for the development of some novel capabilities that can be used in armed conflict, in terrorist/hostage situations, and in training’ and ‘new weapons that offer the opportunity of control of an adversary … can be developed around this concept’.

The surveillance technology of today is the surveillance of the human mind and, through access to the brain and nervous system, the control of behaviour and the body’s functions. The messaging of auditory hallucinations has given way to silent techniques of influencing and implanting thoughts. The development of the terahertz technologies has illuminated the workings of the brain, facilitated the capture of emitted photons which are derived from the visual cortex which processes picture formation in the brain, and enabled the microelectronic receiver which has, in turn, been developed by growing unique semi-conductor crystals. In this way, the technology is now in place for the detection and reading of spectral ‘signatures’ of gases. All humans emit gases. Humans, like explosives, emit their own spectral signature in the form of a gas. With the reading of the brain’s electrical frequency, and of the spectral gas signature, the systems have been established for the control of populations – and with the necessary technology integrated into a cell-phone.

‘We are very optimistic about working in the terahertz electromagnetic spectrum,’ says the principal investigator of the Terahertz Microelectronics Transceiver at Sandia: ‘This is an unexplored area, and a lot of science can come out of it. We are just beginning to scratch the surface of what THz can do to improve national security’.

Oh yeah. I feel safer already.
