The 31 inventions that Britain really needs

‘Get Brexit done, then Arpa’ read Dominic Cummings’s WhatsApp profile. Arpa was what’s now the American Defense Advanced Research Projects Agency. Mr Cummings has departed, but our very own British Arpa has arrived. Downing Street has tweaked the Yankee acronym to ‘Aria’ — the Advanced Research and Invention Agency. Its aim? ‘High-risk, high-reward’ scientific research. The cost? £800 million over four years.

Ludicrous, no doubt: one of those fast-forgotten ‘eye-catching initiatives’ beloved of our leaders. But it got me thinking. We’re responsible for so many of the world’s great technologies and inventions. Steam engines, electric motors, television, telephones, incandescent light bulbs, the jet engine, computers, the world wide web, penicillin… What new achievements could lie in store? Where are the great unmet needs of we British?

I’ve been asking around. On the basis of my own and friends’ thoughts, I’ve drawn up a preliminary list. Through these pages, I now submit the following proposals to Aria for consideration — just to kick things off.
