Hoshino debuts "biodegradable" FD-300 flash drive


It's far from the first company to attempt to make a more environmentally-friendly flash drive, but given the near disposable nature of them these days, that's not exactly a bad thing. This latest drive from Hong Kong-based Hoshino also takes a decidedly different approach than other drives that simply keep the hazardous chemicals and whatnot to a minimum, with it actually constructed out of polylactide (or PLA) made from corn that is, technically, biodegradable. The downside is that in order for it to be broken down, PLA needs to be blasted with heat for ten days on end at a specialized facility, which isn't exactly the most direct route back into the ground, or an accessible option for everybody at the moment (there's also the small matter of it being based on a food product). The drive also apparently isn't available to the general public just yet, but companies interested in doing business with Hoshino can contact 'em for more details.

The corntop lives: Fujitsu showing off mostly-biodegradable notebook

We're not exactly sure what became of that biodegradable laptop being touted by NEC all the way back in 2004, but the concept of corn-based notebook casings is far from dead, with Fujitsu showing off just such a machine at this year's CES. According to Inhabitat, "the main component is polylactic acid, also known as PLA, a resin that comes from the fermentation of the raw biomass from plants," although a small amount of nasty fossil fuels must still be mixed in to create a housing with the proper structural integrity. Fortunately, once the rig is ready for the great gadget heaven in the sky, the plastic can be separated from the PLA so that the latter material can be left to safely biodegrade. No word yet on when we'll see these edible inedible lappies hit the market, so for now we'll have to continue kicking Mother Nature's ass with our biannual tech upgrades.

Foster's to aid in first "beer battery" fuel cell project

While it's certainly debatable whether beer is to thank for the explosion in the consumer electronics industry, it looks like we'll be thanking the beverage without hesitation for making our world a little greener. Oddly enough, "scientists and Australian beer maker Foster's are teaming up to generate clean energy from brewery waste water by using sugar-consuming bacteria," and better yet, the University of Queensland will host a microbial fuel cell at a Foster's Group brewery near Brisbane. Essentially, the cell will consume brewery wastes such as sugar, starch, and alcohol, while producing clean electricity by harnessing the energy released from the organic materials coming in. The device is expected to produce two-kilowatts of power, and while hopes are to bring the technology to other breweries and wineries around the country, this iteration should crank up sometime in September.
