"In London, scientists are creating prototype invisibility cloaks using metamaterials to bend light around objects, and we discover the science behind new technology allowing the blind to 'see' through taste using hi-tech sunglasses.
In Kentucky, USA we visit the small town where a local farmer invented wireless telephones over 100 years ago. Or did he? Finally in Tasmania, we meet our Inventor of the Week who, after being told it was impossible, invented and made his own unique prosthetic arm."
Their support website is encouraging inventions. I found this quite interesting:
For this you hold two phones the wrong way round on both sides of your head and correspond with a partner doing exactly the same - the effect is being able to hear what they are hearing. "Its like being inside your head!"
Building robots!
