Steve Caplin on Sony selling 100m Playstation 4s, on contact lenses that can zoom in, on harvesting electricity from walking, on how one person can drive two trucks at once, on an autonomous pod with wheels that rotate 360 degrees, on an e-bike with blindspot assistance, on snail slime's effect on ageing and how tickling your ear can slow the ageing process. All this and the Cobham tea room with a robotic waitress called Theresa.
