Solar powered sponge that boils water

MIT have created a bubble-wrapped sponge structure which boils water using only the suns heat. This relatively low tech and inexpensive solution could provide a sustainable alternative to the kettle and hot could even be used in hot water systems.

The study was led by George Ni and Gang Chen and was published in ‘Nature Energy’ this week.

“It was relatively low optical concentration,” Chen says. “But I kept asking myself, ‘Can we basically boil water on a rooftop, in normal conditions, without optically concentrating the sunlight? That was the basic premise.”

The design uses a sponge like material made of graphite and carbon foam covered in a thin, blue, metallic-like film which absorbs radiation in the visible light spectrum but doesn’t radiate infra-red which means it keeps in the heat.

6 ways to save the planet that are pretty good excuses to be lazy

Life can be pretty exhausting sometimes, so many tasks to get through and so little time. Wouldn’t it be great if you could just take a break? Here are 6 ways you can be lazy to save the planet:

1) Wash your clothes less – Save up clothes and only wash a full load. Wash at lower temperatures too – washing in warm water will get your clothes just as clean as hot if you aren’t fighting heavy stains.

 

 

2) Take your car to the car wash – They use half the water it takes to do it yourself.

3) Pay your bills online – it saves paper and reduces greenhouse gas emissions, so there’s another good reason for sitting at home in your pants surfing the web.

 

4) Use a dishwasher – instead of handwashing, but only when it’s full

5) Slow down – does life need to be so fast? Take it easy, driving at 50mph uses 25% less fuel than 70mph

And if anyone is judging you, you can just say ‘Hey, I’m saving the planet’
