Roll up, roll up for your Friday dose of green news nuggets, including the new eco restaurant from the team behind Acorn House, the launch of Big Wardrobe and word on ground source heat pumps in Cornwall.
Acorn House grows a green-powered Water House
The crew who brought us fab local food restaurant Acorn House have opened a new venture (pictured above). SmartPlanet rocked up last night to sample tasty modern European-style canapes and check out the Acorn-like aesthetic at the Water House's opening in Hoxton. The restaurant's impressive credentials stem from a heat pump in the canal out the back to provide carbon-free heating and cooling, plus a hydroelectric system and solar panels providing free green electricity.
Big Wardrobe takes on Whatsmineisyours.com
Fancy swapping that old cardie for a new dress? Or swapping those last season jeans for a new tee? Check out landfill-fighting clothes swap site Big Wardrobe. The idea's not new, but the site design's slick and there are already over 100 items the blokes' section and more than 200 in the women's.
Waitrose phases out pig farrowing crates
One of our favourite ethically minded supermarkets has made its bacon more ethical by cutting out suppliers that use farrowing crates for pigs. The crates, which are common use in Danish pig-rearing, are about as inhumane as they come. With farrowing crates, a sow is contained with a tiny metal frame within which it only has room to stand up or lie down. It also means it's unable to get up close to its piglets, which are kept next to it, but outside of the frame. Waitrose, we thank you for making our bacon butties easier on the pigs and on our consciences.
Combat climate change
Chat to and hear from scientists working on the frontline of developing new technologies to slow down climate change later this month at the Science Museum's ever-excellent Dana Centre. The event on 28 Feb is free but you need to pre-book.
Cornish homebuilder plumbs ground for eco heat
Home-builder Rosemullion Homes is taking advantage of Cornwall's naturally warm ground by installing ground source heat pumps at a new development called The Orchard. The pumps basically use pipes underground that act as reverse fridges, handily providing carbon-free heating for the new homes.
