This week on TreeHugger, nuclear-powered cars, portable blow-up bubble houses, apple solar-powered chargers, transformer trench coats, plush polar bears doubling as energy detectives, and more.
The plush toy would communicate with the home's electricity meter, and glow various colors based on the energy use. The pinker it gets, the worse the house is doing on conservation efforts.
This whimsical design by Greendixlooks really fun and useful. It is geared toward iPhones and so is of course a white apple, but with lovely solar-powered leaves.
Something melty and psychedelic to do with all those wine bottles you have piling up in the corner.
Made from cardboard, yet keeps its fancy flair.
What's not to like; it is more of a bivy sack than a tent, but a lot of people camp like that.
Are portable blow-up houses really all that great?
Speaking of portable housing...
Called the "Meguru," it's a spin on the traditionally man-powered vehicle that first appeared in Japan at the end of the 19th century and that has since spread around the world.
With perfect hindsight, we see that the Ford Nucleon was not just a few years from an assembly line, but would remain a footnote in history, alongside so many other totally cool concept cars.
