Grape pits

Harvesting grapes in mini-craters on a volcanic crater on Lanzarote, the easternmost of the Canary Islands.

“An archipelago 100 kilometres to the west of Morocco, the Canary Islands have produced wine for more than 500 years — “marvellous searching wine”, as Shakespeare noted in his play Henry IV.

But vineyards on Lanzarote date from the mid-18th century, following six years of volcanic eruptions that blanketed the island in black ash.”

The craters are dug out and used to shelter the vines from prevailing winds.


DIY Pee-Powered Phone Charger

“The Bill and Melinda Gates Foundation has funded research to develop a pee powered smartphone battery… but you can make one right now. Lemon batteries are cool, but salt batteries are powerful. And, hey, there’s salt in urine, so a urine powered battery would be the ultimate emergency battery to top off you cell phone, right? Sure, if you’re squeamish, you can use salt water instead o’ urine! We show you how to build a battery from aluminum foil, copper wire, charcoal, and salty liquid that’ll charge a smart phone in the video!”
