Product of the Year.
Steve Caplin and Simon Rose look at the latest in high- (and low-) tech. Kyoto University have produced a face mask that can detect Covid, while Amazon are now selling PCR tests. Scientists have developed a phone security system that relies on how you walk, commercial-sized planes using liquid hydrogen and a yacht that makes its own hydrogen from seawater. With wearable electronics becoming more popular, Canadian boffins have come up with a washable battery while some in Japan have devised a bus that is also a train - and vice versa.

There's an LED-lit zebra crossing, Adele putting an end to album-shuffling on Spotify, which has added lyrics to its songs, 8 million of them. There's crowd-funding for a gizmo that cancels out spurious noise when you're working at home and the Japanese are using discarded adult nappies to heat public baths.

If you've a bored dog, then DogTV is here, aimed at the canine viewer, while lab-grown fish could soon be on the menu.
