Steve Caplin, Share Radio's technology editor, looks at Google's 3D video chat system, the return of airships, Einstein's e-mc squared letter, the installation of the swimming pool 35 metres high, a hydrogen engine with only 20 parts, an electric Popemobile, an anti-hacking system, how a man blind for 40 years has recovered his eyesight, a 3D-printed electric scooter and he discovers just how prescient rocket scientist Wernher von Braun was in one of his science-fiction novels.
