This week at TreeHugger: We put hands on the Hymini, the portable power bank universal adapter cum wind and solar generator, in a new hi-definition video. Gmail is a great way to stay in touch without actually having to talk to anyone, but what're the green implications that come with never deleting another email?

The Big Apple announced plans to become the first US city to require electronics recycling; no small feat considering the city's residents buy 12 million gadgets a year. Lastly, Nokia's "Remade" cellphone concept sure talks a mean green game, but all that glitters is not green. Or is it?

The Hymini, the portable power bank universal adapter cum wind and solar generator, has generated as many questions as it has power, to this point: how much wind does it take? How do you pronounce it? And what sort of sexual funny business does the name refer to? We got some answers at the recent Greener Gadgets Conference, in this exclusive video (it's even in hi-definition!).

Okay, so Gmail has become the de facto form of communication for many of us, but there's gotta be some sort of cost associated with never deleting another email, no? Moving from paper to digital storage is leading to major increases in energy consumption, and Google itself acknowledges it is "as much of an energy glutton as heavy industry." But just how much energy are we using up by not keeping our Gmail inboxes in order?

New Yorkers currently dispose of more than 25,000 tons of discarded TVs, computers and other electronic equipment, which is hardly surprising because it seems they also buy 12 million electronic gadgets and do-dads every year, amounting to about 92,000 tons in total. Deciding that those numbers are just one cellphone too many, the Big Apple's City Council voted to make manufacturers responsible for the take-back of their electronic gadgets. Don't go running to the basement for your pile o' gear, though; the ruling wonít become effective until July 2009.

Lastly, the Wall Street Journal tells us that "Nokia Corp., the world's largest mobile-phone maker by sales, unveiled a new handset made of no new parts. Called 'Remade,' the handset uses 100% recycled pieces, the latest in the company's push to go green, Olli-Pekka Kallasvuo, chief executive of Nokia, said yesterday at the Mobile World Congress in Barcelona." That would be nice, but from what we can tell, they really released a non-functioning model and a video "showing a new concept from our design team exploring how recycled materials could be used to make mobiles in the future." In other words, vaporware. And that ain't so green, just yet. Release the hounds!
