Share Radio's technology editor Steve Caplin pays tribute to the inventiveness of the late Sir Clive Sinclair, inventor of the pocket calculator among other things - even though he always used a slide rule. He gives a Tesla a test drive, including its built-in whoopee cushion, admires a new microcar, looks forward to streets lit by glow-in-the-dark plants, explains why the Lithuanian government is warning people about Xiaomi phones, recommends an auto cutout app and highlights the latest IgNobel Prizes, one of which says sex is better for clearing the nose than decongestant.
