HP launches environmentally friendly rp5700 slim desktop PC
As the green trend looms ever larger over the consumer electronics industry, HP is taking full advantage of the opportunity by unveiling the environmentally friendly rp5700 slim desktop PC. The company toots its own horn by boasting about the Electronic Products Environmental Assessment Tool (EPEAT) Gold award that the machine has garnered, and we'd assume that building it from 95-percent recyclable components and packing it in a box made from at least 25-percent post-consumer recycled cardboard had something to do with it. Additionally, the unit sports an uber-efficient power supply and comes with "an optional solar renewable energy source" to extract juice from the sun. As for hardware, you'll find Intel Core 2 Duo chips up to 2.13GHz, up to 4GB of DDR2 RAM, SATA hard drives as large as 250GB, optional RAID 1 setups, and your choice of operating system. Of course, the EPEAT Gold-certified machine steps it down to a Celeron 440 CPU with 512MB of RAM, and while this particular configuration will start at $817, other options are available today from $648 right on up.[Via Slashgear]
Thermoacoustics behind all-in-one cooker, fridge, and generator
Sure, building up a campfire in order to roast some eats in the wilderness could be fun for awhile, but for the reported "two billion people that use open fires as their primary cooking method," we're sure it loses its luster somewhere along the line. The University of Nottingham is hoping to change all that, however, by attempting to develop an all-in-one gizmo that acts as a "cooker, a fridge, and a generator," and relies on biomass fuels for energy. The £2 million ($3.96 million) SCORE (Stove for Cooking, Refrigeration and Electricity) project seeks to create a "wood-powered generator capable of both cooking and cooling food," and it will purportedly rely on thermoacoustics to cut down on pollutants, increase efficiency, and be more reliable to future consumers in Africa and Asia. No word just yet on when this newfangled kitchen appliance will be ready to ship, but a portable version would probably do quite well in the camping market.[Via CNET]
Toyota looking to go hybrid-only by 2020?
Be warned, you should certainly take this one with a helping or two of salt, but according to a report over at Motor Authority, Toyota's Masatami Takimoto has at least insinuated that by 2020, hybrid vehicles would account for "100-percent" of the automaker's fleet. Of course, the context of the conversation was surrounding the firm's recent report that it expected to "make as much money on hybrids as it does on conventional gasoline-powered cars by 2010," so all sorts of boasting was likely to be aimlessly floating out of higher-ups' mouths. While making such a bold claim can't be seen as entirely unrealistic, we have to wonder if purely electric whips won't have at least some presence in the mainstream automotive market (and Toyota's lineup) within the next 13 years.[Via Edmunds]
University of Edinburgh crafts energy efficient FPGA supercomputer
Considering that ATI and NVIDIA don't seem to be making any substantial strides in reducing the amount of energy required to run their products, it's a tad surprising to hear of an entire supercomputer running a bit leaner than the competition. Hoping on the ever-growing green bandwagon, University of Edinburgh developers are at it again, this time crafting an uber-speedy machine that's reportedly "ten times more energy efficient and up to 300 times faster than its traditional equivalents." Based on field programmable gate arrays (FPGA), the chips are not only very difficult to program, but they can currently only be used "to perform very specific tasks." Of course, the creators are more interested in the extreme number crunching and power saving abilities than anything else, and while no commercial uses have been identified just yet, the machines could purportedly be used in fields such as "drug design, defense and seismology."[Via CNET]
AIST turns transparent glass into mirrors to conserve energy
We've seen two-way displays and undercover mirrors before, but the latest two-faced invention to come from the depths of the National Institute of Advanced Industrial Science and Technology (AIST) can pull double duty in regard to purpose and save a little energy in the process. The "switchable glass" has certain reflexive properties created by the twin coatings of "40-nanometer-thick magnesium-titanium alloy, plus a 4-nanometer-thick layer of palladium," which allows for the mirror to become transparent when a small amount of hydrogen is introduced between the two panes. Alternatively, tossing in a bit of oxygen forms a reflecting mirror, allowing users to "switch" the glass by injecting gases. Contrary to other commercialized approaches, this rendition can purportedly result in up to a "30-percent savings in energy costs" by having to run your air conditioner less, but there's still work to be done. Scientists at the AIST are still toiling away as they try to fight the relatively rapid deterioration that occurs from "frequent switching," but if they can add a dash of durability and get the price down to a respectable level, we could all be living in a house of mirrors before too long.[Via PlasticBamboo]
