Share Radio's technology editor Steve Caplin gets excited by trials of a hydrogen-powered train which, it is hoped, might appear in passenger service in 2023. David Attenborough achieves a record for speeding to 1m followers on Instagram, Amazon reveals a host of new products - including one that seems rather creepy - and also unveils a palm scanner while others think 3D vein scanning could be the way to go. There's a foldable PC, a super enzyme that eats plastic, a smart bike light seeking crowdfunding, a pop-up restaurant on a plane, how seaweed could help with your cleaning and a jet suit for paramedics in the Lake District.
