A car designed by teenagers that gets nearly 2000 mpg, white roofs for New York City, and how your DVR is jacking up your electric bill… this week’s green tech finds.
Puma’s “clever little bag” is biodegradeable: We mentioned Puma’s alternative to the shoe box back in April of 2010; PSFK reports that the bags will also be compostable (or, if you’re impatient, they’ll dissolve in water in a few minutes). (via Environmental Leader)
The 2000 mpg car? OK, not quite… this design by students at Kingdown School in Warminster, UK got a mere 1,980 mpg. That was more than enough for it to win the Mileage Marathon Challenge at Mallory Park track near Leicester. (via Inhabitat)
