The UK government is considering the legalisation of skywriting, six decades after it was banned during the Cold War. If it goes ahead, we could see advertisements, marriage proposals and other messages written in the sky by the summer. Can the dying art be revived to take aviation to dizzy new heights or is it just pie in the sky?
Electric trees
Catalina Lotero, an industrial designer, believes we can harness the static electricity produced naturally when leaves brush against each other to power homes in remote off-grid communities. The technology is in its early stages, but Lotero says a single tree could provide enough electricity for seven homes.
Legal weed
Cannabis was legalised in Canada 18 months ago, but the nation’s marijuana black market is booming. Weed aficionados point to high prices and poor quality as the reason they are sidestepping legal traders, favouring instead their old dealers. The boon for underground dealers, meanwhile, has wiped billions of dollars off the values of the industry’s largest companies, in a collapse that is being compared to the dotcom bubble.
