Google's got a robot dog that stalks indoors, haunts dreams
This is how it starts: you feel bad seeing the robot "dog" get kicked, and the next thing you know it's nipping at your heels, pushing you back to work in the salt mines. Instead of using the film and TV trope to illustrate how morally bankrupt a villain truly is, Google-owned Boston Dynamics employs it to show off "Spot": its latest quadruped, with an amazing ability to self-stabilize. The bot appears considerably more lithe than the AlphaDog it races up a hill, and can even roam in a tight pack with another unit. And unlike the diminutive Little Dog, Spot has a sensor-laden "head" that Boston Dynamics says helps it conquer a variety of ground cover.
Fanatec's Clubsport pedals V2 bring improved brake and clutch feel to the virtual speedway (video)
Around these parts, we're generally suckers for all things related to racing simulators. As such, we're excited to learn that Fanatec has unveiled its next generation of the Clubsport pedals that we reviewed over a year ago. Dubbed as the Clubsport pedals V2, the company refers to the peripheral as an "evolutionary" update to original, offering a trio of improvements. The clutch has been retooled to have a "regressive feel" that's said to be similar to a real automobile, while the brake is now of the hydraulic variety, featuring user replaceable synthetic oil -- naturally, it still has an adjustable spring and load cell pressure sensor for the utmost customizability. The final touch is merely some visual spice in the way of black anodization. Notably, there won't be any tuning kit available initially, and V1 owners might be disappointed to know that the company has opted not to offer an upgrade kit, citing costs and potentially complicated installation. Fanatec is aiming to have the Clubsport pedals V2 out by June, bundled alongside its Clubsport wheel, with pricing set at $250 for the US (€250 in the UK). Pre-orders won't begin until May, so in the meantime, shift over to the source link below and the video past the break for all the details.
Inhabitat's Week in Green: floating trains, dead bees, dirt-powered phones and Cornish pasties
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. Did you know that the cell phone in your pocket could be causing the collapse of bee colonies? This week Inhabitat reported the alarming news as Swiss researchers confirmed that cell signals confuse bees and are leading to their deaths. We also looked at a Bill Gates-funded plan to power cell phones using dirt, and we spotted a new phone battery that can be charged by yelling at it -- much to the chagrin of everyone else on the bus. Alternative transportation got a boost this week as Japanese engineers unveiled a levitating high-speed electric train that flies over the earth, and we shined a light on Berkeley's new solar-powered Impulse racer, which is gearing up to blaze a trail in the 1,800-mile World Solar Challenge. It was a big week for biofuels as well as Ford and Georgia Tech unveiled plans to create the first hydraulic hybrid U.S. school bus and UK scientists cooked up a plan to power cars with Cornish pasties. In other news, this week a New Jersey Toys "R" Us unveiled plans to build the largest solar roof in the United States, and HyperSolar rolled out a magnifying film that can increase the efficiency of photovoltaic panels by 300%. In green lighting news, we watched Google flip the switch on its brilliant Android-controlled LED bulb, and we announced the Philips and Inhabitat Bright Ideas Lighting Design Competition, which is awarding $1,000 to the designer of the most stunning eco-friendly lamp. Finally, we got excited for the start of summer with a look at the Lapin Kulta Solar Kitchen, which will be serving up sun-cooked meals all across Europe!
Chrysler announces battery-free hydraulic hybrid tech, compresses gas to make power
Think of a traditional hybrid and you probably think of a Toyota Prius. Then, after you've woken from your nap, you probably envision some complex system of batteries and electric motors and gears to capture power when braking and spit it back out when accelerating. Chrysler is now looking to deploy a different way, a seemingly much simpler way that's all based on hydraulics. The vehicle is outfitted with a low-pressure reservoir of hydraulic fluid and a high-pressure chamber filled with nitrogen gas. When braking, pumps move the fluid into the nitrogen chamber to compress it and then, when accelerating, that compressed gas is used to push the fluid and drive the wheels. It's a setup that was actually developed by the EPA and is currently in use by some commercial vehicles, most notably UPS trucks, but a hybrid Town & Country minivan could bring it to consumers -- though not until 2012 at the earliest. Now, there's a good chance the idea of a hybrid minivan is threatening to put you back to sleep, so we wish you pleasant dreams.
NASA's robot submarine achieves perpetual motion, of a sort
The Sounding Oceanographic Lagrangrian Observer Thermal Recharging (SOLO-TREC) autonomous underwater vehicle is, well, quite a mouthful. It's also the first submarine that can run a sizable percentage of forever without requiring a charge. When the 183-pound buoy dives, cooler water temperature causes a liquid wax-like substance inside to solidify, squeezing out oil that drives a hydraulic generator; when it surfaces, the wax softens once again, ready for another round. Every dive produces 1.7 watt-hours of electricity, enough to power all the instruments, GPS and buoyancy-control pump on board. It's like a drinking bird that never runs out of water. Designed by NASA's Jet Propulsion Laboratory and Scripps researchers, the thermal engine is envisioned as an oceanography tool... but since the US Navy also has a finger in the pie, don't be surprised if it plays a minor role in the coming robot apocalypse as well.
Eaton's fuel saving hydraulic hybrid systems put traditional drivetrains in jeopardy
Eaton, which is better known for its involvement in supercharging muscle cars, has a thing for saving fuel, too. According to a writeup on the outfit's website, it's working up a series hybrid hydraulic system to replace the conventional driveline. The SHH system will wed a high-efficiency diesel engine and a custom hydraulic propulsion system, and by operating at its "sweet spot," it stands to reason that lots of gasoline will be saved as it runs. Better still, the setup involves regenerative breaking in order to recover and reuse energy that's typically wasted, and the engine can safely be shut off when not needed in order to save additional fuel when waiting at a stoplight. So, where is this stuff headed first? UPS trucks, naturally.[Via Autoblog]
Hydraulic transmission gives engines, wallets a break
Another day, another potential find to avoid the imminent fuel crisis. On the docket today is Ernie Brookins' hybrid drive system, which "captures, compresses, and stores wasted drive-train energy produced when a vehicle's engine is running." Ernie here has concocted a hydraulic transmission that can reportedly power vehicles without the engine running all of the time, and he expects the solution to save motorists around 50-percent in fuel costs. Better still, the contraption could theoretically work on nearly any vehicle -- from school buses to grain trucks to high-octane Power Wheel Jeeps. As these things seem to always go, the project has hit a roadblock without a source of funding, so if any VCs out there are looking for a somewhat solid place to shove $250,000, give this man a ring.

Portasol Solar Tracker continuously faces the sun
Although solar panels are becoming more and more efficient, one of the most glaring oversights in solar technology has been the inability for panels to autonomously move along with the sun and maximize the energy it could take in. The Portasol Tracker, however, is aiming to change all that, as a market-ready rendition is finally set after seven years of testing. The Hydrasolar panel utilizes hydraulic motors along with sophisticated "passive solar trackers to affect the thermal expansion and contraction of a contained liquid to make the device rotate." Essentially, the movement of the liquid causes the panel to spin to the west along with the sun as the day passes on, ensuring that the maximum amount of energy is garnered during those precious daylight hours. Currently, a small selection of models and mounting options are becoming available, and while hard pricing doesn't yet seem to be available, feel free to hit the links below for a smattering of pics and even a quick video overview.[Via MAKE]
