Swedish designer Peter Thuvander has come up with the iYo YoYo, a nifty green alternative way to charge your iPhone or iPod.

“To celebrate my new Iphone and the fact that darkness is looming over me. I´ve done this: An induction powered yoyocharger for Apple.

And since solarchargers don’t work at night or in Sweden half the year, this should be a smash hit.”

Thanks to a small Li-ion battery inside the yo-yo you build up a charge while you play with the iYo YoYo. Afterwards you can just plug in your iPod or iPhone and it will be charged.

Apple recently released their new line of MacBook and MacBook Pro laptops, which are mainly made from aluminium. They say that they are their greenest latops ever and claims that they are “highly recyclable and even more energy efficient”, and that they are “designed with the environment in mind”.

But really, how green are the new laptops?

Greenpeace, who is running a hard and successful campaign for greener electronics, says that the new laptops are “not quite the breakthrough” they “were hoping for”:

“A check of the full specs revealed the MacBook Pro, MacBook and MacBook Air – as well as the LED Cinema Display will now have internal cables free of PVC and will have internal components containing no BFRs. Not quite the breakthrough we were hoping for. These new MacBooks are currently on a similar level of toxics reduction to the Sony Viao laptop series on PVC, and the Lenovo Think Vision in monitors. The BFR free internal components represent an improvement from the bar set by the Vaio line.”

Hank Green, over at EcoGeek, is a bit more negative saying the new laptops are “wasteful”:

“I’m glad to see Apple focusing on the efficiency of their computers, not to mention decreasing the amount of toxic materials they contain. But this new carved-brick process isn’t green, it’s wasteful, and I’m happy to be sticking with my good-ol’ plastic clunker.”

Jaymi Heimbuch, from TreeHugger, on the other hand is a bit more positive:

“It seems that this process allows the MacBook Pro to use 50% fewer parts. In the manufacturing stage, they start with a 2.5 pound piece of aluminum. The end structure is only 0.5 pounds (for the MacBook Air). That means that 2 pounds of aluminum is cut away.

Nevertheless, it looks like this process, despite flaws, has some real improvements for the notebook in the big picture of its lifetime and total footprint.”

Apple explains how green their MacBook and MacBook Pro are on their website.

The Australian Consumer Association recently published a list on Computer Energy Costs for various home gadgets such as your computer screen, DVD player, cordless telephone, gaming console, laptop etc.

Interesting with this list is that it shows how much energy these gadgets consume weekly, monthly as well as yearly, even when they are supposed to be off.

According to the study, the Sony PlayStation 3 consumes 33.34 kWh (weekly consumption) when on and playing a game. That is more than a Plasma TV who uses 29.68 kWh when on and playing a DVD.

When the same game console is off (back switch on) it still consumes 0.30 kWh. Microsoft’s Xbox 360 consumes 0.40 kWh when off and 26.00 kWh when on and playing. The Nintendo Wii is a bit better, it consumes 3.14 kWh when on and playing a game. But it consumes 0.32 kWh when off (WiiConnect24 is off). That is more than PlayStation 3.

“Our tests also found that leaving a PlayStation 3 on while not in use would cost almost $250 a year in electricity bills (charged at 15c per kWh). This alone is around five times more than it would take to run a refrigerator for the same yearly period.

The Xbox 360 was not far behind the PlayStation 3 in energy usage costs per year, serving as an important reminder to turn off videogame systems after use.”

The only way to be sure these energy hungry gadgets don’t consume energy (and your money) is to make sure they are switched off and unplugged when you are not using them.

But now the campaign has run into some problems. Apple, the computer company, doesn’t like the GreeNYC logo – which resembles an apple.

Apple has filed a formal opposition (.pdf) arguing that the GreeNYC logo will cause “mass confusion and ruining Apple’s good reputation.”

The logo is being displayed on advertisements, public transportation systems and other similar places and products. For example the logo will be on a limited-edition 100% organic cotton shopping bag.

In 6-9 months a decision is expected to be made by the Trademark Trial and Appeal Board of the patent office in favour of New York or Apple. Wired has more about this story.
