Nanofabrication engineers have built the first on-chip device that exploits the Casimir effect
One of the strangest effects to arise from the quantum nature of the universe is the Casimir force. This pushes two parallel conducting plates together when they are just a few dozen nanometres apart.
Greenery may fulfill a superficial need to improve the landscape aesthetic, but plants play a much more critical role in regular life function, converting carbon dioxide to oxygen through a process called photosynthesis. Panasonic is among the companies attempting to replicate this natural procedure through artificial means, and it looks like the Japanese electronics maker is well on its way towards a viable solution. Presenting at the International Conference on the Conversion and Storage of Solar Energy this week, Panasonic announced the development of an Artificial Photosynthesis System, which uses a nitride semiconductor to convert water and carbon dioxide — a byproduct of factories and power plants — into an organic material called formic acid, which is used in the manufacturing of dyes and fragrances. Covering the planet in formic acid wouldn’t necessarily represent progress, but assuming demand isn’t exceeded, it certainly beats CO2. Best yet, Panasonic claims that the system converts the substances at plant-like efficiency rates, or 0.2 percent. Hit up the PR after the break for a more granular look at the company’s creation.

Despite plenty of indications that the Earth has gotten warmer—like melting glaciers and ecosystems that are shifting toward the poles—there are a number of climate skeptics who simply don’t accept the temperature records produced by three different organizations (NASA, NOAA, and the CRU). Many of them pinned their hopes on physicist Richard Muller, who was also not convinced the professionals had gotten it right. But Muller did something about it, forming the Berkeley Earth project, and building a huge database of land temperature records.
Back in October, Muller dropped his findings in a rather unconventional location: an editorial in The Wall Street Journal. Despite the hype, the results were rather bland. He produced a temperature record that was nearly identical to that of the other organizations. But now, Muller is back for round two, and this time he has chosen the New York Times as an outlet for his climate musings.
As before, his team uses a different statistical method of reconstructing temperatures that works well with short records, taken at sites that were shut or moved. NASA, NOAA, and the CRU use methods that require long records, so they have to make adjustments to the data from sites that have shifted or gotten new equipment. This compensates for the fact that these changes will lead to discontinuities in the record. Since Berkeley Earth doesn’t need the same length, it can just skip adjustments entirely: any record with a discontinuity is just split there, and treated as two records. The team has now also pushed its analysis back to almost 1750, adding a century to the land temperature records produced elsewhere.

Suidobashi Heavy Industries has put the finishing touches to its latest project, the 4.4-ton Kuratas. Mobile suit obsessives around the world can thank artist Kogoro Kurata and robotics expert Wataru Yoshizaki for the robot frame, which has space to house a pilot inside. The mech’s touchscreen UI even includes a Kinect-based movement interface and the shudder-inducing “smile-activated” twin BB gatling guns. You can customize your own diesel-powered beast in the dystopian gang colors of your choosing, but be advised: the $1.35 million price tag doesn’t include further customization options like a faux leather interior, cup holder or phone cubby. The Kuratas does, however, come with the ability to make phone calls direct from the cockpit, so you can tell your enemies that you’re coming for them.

Solar may be the green energy source that’s been hogging the headlines lately, but there are other fossil-fuel free ways that can help meet society’s electrical needs. One of these is tidal power, and the US is set to start harnessing the ocean’s electricity-generating potential this summer with the TidGen Cobscook Bay project — the first such commercial project in the States. Located just off the coast of Eastport, Maine, turbines will be placed in 50-100 feet deep water to take advantage of the 100 billion tons of water that flow in and out of Cobscook Bay each day. When the project goes live, it’ll feed into the public power grid and generate enough juice to power between 75 and 100 homes, and the plan is to eventually install enough turbines to generate 3MW of power — which should cover the needs of over 1,000 homes and businesses. There’s more info, plus plenty of political self-congratulation in the source below.

One of the biggest changes ever made to WiFi is coming in the next year with a new standard supporting the 60GHz band, powering much faster transmissions than are possible in the existing 2.4GHz and 5GHz bands. All that’s needed are some chips, and products to put them in.
Slowly but surely, the chipmakers embracing 60GHz technology are making their plans known. The latest is Marvell, which today announced a partnership with startup Wilocity to make tri-band chips that will use all three bands. That will allow consumer devices to connect to existing WiFi networks while also taking advantage of the super-fast 60GHz band for high-speed data transfer and high-quality media streaming. Under the developing 802.11ad standard, 60GHz transmissions can hit 7Gbps.
Wilocity already has a partnership with Qualcomm Atheros, Qualcomm’s networking subsidiary, to build tri-band chips. Those are expected to come out by the end of this year and focus on the PC notebook market—for example a laptop bundled with a remote docking station. The partnership with Marvell won’t result in shipping products until 2013, but Wilocity’s VP of Marketing, Mark Grodzinsky, told us that the Marvell/Wilocity chips will focus on a broader range of products including tablets, Ultrabooks, and phones. The two companies are also targeting access points, residential gateways, and media center devices.
