For anyone with a modest interest in Science and Technology, this was a corker of a program last night. Michio Kaku, an actual Physicist (unlike many presenters who know sweet FA) took viewers through the big emerging technologies. Fusion Power, Nanotech, Superconductors, Bioengineering, etc.

The problems with developing each technology, the potential they hold and the problems they may cause were looked at thoroughly, in easy to understand language but not dumbed down.

According to some of the professors, the rate of technical change is doubling each decade, a bit like Moore's law but for technology as a whole. And apparently, the next generation of tiny robots will be able to travel into the human body, controlled by computer. They also pointed out that nanotech is working towards a "molecular assembler", just like in Star Trek, that can assemble objects from atoms captured in the environment.

It's worth wearing a sceptical hat for some of the program, but if it gets a repeat (hey, this is BBC4), watch it.
