The Hypocritically Bold Look of Kohler
Taryn, an EcoGeek reader, received her subscriptions to Wired Magazine as well as National Geographic this week. A very EcoGeek combination, I must say, keeping up on the beauty and diversity of our world as well as cutting technology. But what she found surprised her. Each magazine had an ad from the same company, from the same advertising campaign with some disturbingly different messages.
The ad in National Geographic brags about Kohler's "commitment to creating water-saving products". On the other hand, the full-page advert in Wired seems to indicate that true luxury can only be had in a shower that simulates the drenching power a category five hurricane...an experience Kohler will gladly provide you with.
So which of these is the Bold Look of Kohler: The one that promises "Bold Conservation" or the one that promises "Bold jets of watter hitting you with one gallon per second of fresh drinkable water from every conceivable angle"? Thoughts?
Vortex-Creating Wind Turbines Could Double Wind Farm Output
An egg-beater-like vertical wind turbine design could potentially double the output of wind farms by using the space between larger, horizontal turbines.
Wind farms take up a lot of land because the large rotating blades of the turbines need a lot of space in between them to operate safely and effectively, but company Wind Harvest International thinks wind energy could be generated in those empty spaces. The company claims a MW array of their shorter, vertical turbines could fit in the space between two horizontal MW turbines.
The Wind Harvest turbines work in groups of three or more to maximize their energy output. The turbines alternate between clockwise and counter-clockwise rotation, creating a vortex that accelerates the localized wind speed by almost double. The company says it's also possible that the arrays could boost the energy output of the larger horizontal turbines as well, but that more testing would have to be done to confirm that.
Other than utilizing all of the land in a wind farm, the vertical turbines could also act as a back-up for the horizontal ones. In extreme wind speeds where large turbines have to be shut off, the vertical turbines could keep generating electricity. The company also plans to market a turbine for low wind speeds.
Wind Harvest plans to have 25 and 75-kW versions available commercially in 2011.

California Considers Mandated Grid Storage
Legislators in California have introduced a bill that would require electric utilities to provide grid-scale energy storage in their operations. The bill would call for a capacity of 2.25% of daytime peak demand by 2014 and 5% of peak demand by 2020.
A variety of technologies could be included in the mix to provide grid energy storage, including pumped storage hydro, compressed air storage, utility-scale batteries, and flywheel storage systems.
This may have the indirect effect of encouraging the utilities to promote efficiency measures and to encourage load shifting, in order to lower the amount of storage that would be required.

INGOCAR is a developmental concept for a 5 passenger car with a hydraulic drive system in place of a conventional powertrian. With the weight reduction this offers and other efficiencies in the systems, the designers say their vehicle could get 170 mpg.
The INGOCAR is a hydraulic hybrid vehicle. Like some electric hybrids such as the Chevy Volt, it uses the motor indirectly instead of using the mechanical motion of the motor to move the car. But rather than using a motor as a generator to produce electricity, the INGOCAR has a highly-efficient 2-stroke diesel engine which is used to pressurize a hydraulic tank called the accumulator. Pressure from this tank is then used to turn individual wheelmotors in each wheel.
Hydraulic power makes the regenerative braking of the INGOCAR much more efficient than that in electric motor vehicles, as well. Regenerative braking with hydraulics is able to recover 75 to 85% of the energy which is used to repressurize the system. The wheelmotors that serve as both propulsion and braking for the vehicle are smaller than the disc brakes they replace.
The INGOCAR's efficiencies work to benefit it in several ways. For instance, eliminating the conventional powertrain provides a 30% weight reduction for the car. Also, the engine only needs to run for a short period of time to recharge the pressure tank. It can also be smaller since it is only being used to develop pressure, rather than needing to be strong enough to run the car directly.
The vehicle is able to be significantly lighter than an electric hybrid because the motors are much lighter. "A comparable electric powertrain, able to recapture the entire braking energy, is significantly heavier. The weight of the currently best electric motors is 20 times higher than that of the new hydraulic motor. The weights of the energy storage devices (battery, accumulator) are about the same. As result, the weight of the car would increase by about 50% - from 2200 lb to 3300 lb - consequently increasing the fuel consumption."
The 5 passenger INGOCAR would weigh 2200 lbs (998 kg). The Chevy Volt's curb weight is expected to be around 3500 lbs, and the current Toyota Prius curb weight is also around 3000 lbs.

Alcoa Eyes A Leap Into Solar Industry
Finally, A No-Draw Charger
AT&T has just announced a USB-based telephone charger that does not pull electricity from the wall when it's not charging a phone. I don't know about you, but my charger is plugged in 100% of the time. That charger pulls a tiny amount of energy from the wall 24 hours a day 365 days a year. Multipy that by 100 million chargers in America and there's probably at least one coal-fired power plant in America dedicated entirely to that wasted power.
AT&T's new charger, however, is a standardized USB charger that does not pull any power from the wall when there's nothing plugged into it. You wouldn't think this was a particularly complicated thing to do (especially since chargers routinely cost thirty FREAKING dollars.) But high-markup chargers are a big part of cell phone company's profit models, so they aren't generally interested in pulling R&D dollars from that big tasty pie.
But it works, and it will charge a variety of devices, even non-AT&T devices. It's great news for us all, and at the same cost as a regular (dramatically overpriced) cell phone charger.
Let's hope the technology makes its way into other vampire power culprits soon. Read the full press release from ATT here.

LED Lighting Would Save America $120 Billion
A Department of Energy report on light emitting diode (LED) technology has some pretty startling numbers to digest. First, 7% of America's electricity is used to light our homes and businesses. That number is down significantly in the last few years because of the adoption of efficient lighting. But there is still a great deal of ground to be gained. Indeed, as bright white LEDs begin to make their way to the market, the DOE expects their adoption to result in huge decreases in energy use.
The cumulative savings of widespread adoption of this technology over the next 20 years would be about 1.500 terawatt-hours the price of which, at today's energy prices, is around $120 billion. The savings would eliminate the need for 24 new large power plants, to say nothing of the decrease in carbon emissions.
The DOE has a host of programs to spur growth in the LED market, including a X-Prize style contest, R&D projects and market-baed projects. Of course, we have to do our part too. New technology relies on EcoGeeks to be the early adopters of LED technology. I've already got a few lighting up my house.
China Planning Massive Asia-Europe Rail System
China's high-speed rail plans get more ambitious by the day. Not satisfied with having the world's most advanced and extensive rail line in the world, China is now planning to connect its rail system to 17 other countries in Asia and Eastern Europe where it will join the European rail network.
China plans to have this massive project completed in 10 years. The rail system will include three major continent-crossing lines running at 200 mph. One line will connect London to Beijing in a two-day trip and continue on to Singapore. Another will link Vietnam, Thailand, Burma and Malaysia. The third will connect Germany to Russia, go across Siberia and back into China.
With travelers able to take major routes like these at high speeds, air travel may become a lot less necessary across Europe and Asia.
China will be financing the project in exchange for access to natural resources from the 17 countries the rail lines will run through. As an example, Burma will provide China with lithium for its rail connection.

Bead-Filled Washing Maching Uses 90% Less Water
A new washing machine design uses 90 percent less water and reduces utility bills by 30 percent by cleaning clothes with tiny plastic beads.
The machine by UK company Xeros Ltd uses 3mm-long nylon beads that can get into all crevices and folds of clothing and absorb stains and dirt. Stephen Burkinshaw, a polymer chemist at Leeds University, discovered that nylon beads at 100 percent humidity could attract stains away from clothing and into the center of the beads, preventing deposition back onto the clothes.
The machine uses a small amount of water to dampen the clothes and to reach the right humidity level, then the drum is flooded with the beads. When the cycle is complete the beads drain away with the water to be reused hundreds of times.
I'm sure you've already started questioning what happens to these plastic beads once they're done scrubbing clothes. The company wants to eventually create a closed loop where the saturated beads can be refreshed and reused in the machines, but for the time being they will be collected and recycled.
Xeros says that if all of the US used these machines instead of regular washing machines, it would save 1.2 billion tonnes of water per year and the CO2 emissions saved would equal taking 5 million cars off the road. The machine would also eliminate the need to dry clean many delicates, another environmental benefit. The Xeros machine is expected to be available by the end of next year.

Concentrated Solar Power Isn't Just for Deserts, It Could be for Walls Too
Usually when you read about concentrated solar power, it's referring to some large project destined for the Mojave Desert, but Syracuse's Center of Excellence in Environmental and Energy Systems (SyracuseCoE) has set out to prove that this technology can be used in smaller, colder settings.
SyracuseCoE in Syracuse, NY is itself a LEED-platinum-certified, 55,000 square-foot building that serves as a testing ground for renewable energy and efficiency technologies. The south wall of the building is home to a concentrated solar facade that, at first glance, resembles the frosted cube walls found in doctors' office waiting rooms.
This 8-foot by 8-foot facade houses several clear pyramid lenses that track the sun and concentrate the rays onto high-efficiency PV cells. Extra energy not converted to electricity is used for heating water and radiant heat in the building. And because it's made up of clear panels, it also adds natural lighting indoors. You can watch a video of the system at work here.
Using a concentrated solar power system in an architectural application is a new concept, so the center will be monitoring and reporting on its performance.
The facade was designed by the Center for Architecture Science and Ecology and the company HeliOptix is licensed to market it.

Transonic Combustion Improves Gas Engine Efficiency Over 50%
Conventional gasoline engines are terribly inefficient things. Only 13% of the energy of the fuel actually moves the car. 62% is lost in the engine as waste heat, and driveline losses, accessories, and idling also reduce the efficiency.
Transonic Combustion is planning to build automobile engines with improved efficiency obtained through heating and pressurizing gasoline before injecting it into the combustion chamber. "This puts it into a supercritical state that allows for very fast and clean combustion, which in turn decreases the amount of fuel needed to propel a vehicle," according to MIT Technology Review. A transonic test vehicle achieved 64 MPG in highway driving, compared to a 48 MPG hybrid Prius, and running at a steady cruising speed of 50 mph, the test vehicle achieved 98 MPG.
Like diesel and HCCI, the Transonic Combustion technology operates without needing a spark plug. Timing software also further enhances the operating efficiency of the system. Transonic injection is being developed for use with gasoline engines at present, but will also be compatible with advanced low carbon footprint bio-fuels in the future. Transonic expects its system will be comparable in cost to other current high-end fuel injection systems.
Because of the higher operating pressure, the longevity and durability of the engine will be important considerations the company will need to address. The company plans to build its production facility in 2013 and expects to be building engines for production vehicles in 2014.

Google Maps Adds Bicycle Information
Beginning today, Google has begun providing bicycle directions for its Google Maps service with directions for cyclists in 150 cities in the United States. Google already incorporates public-transit and walking directions in addition to automobile driving directions, and the bicycling community has been calling for Google to add bike routes for some time.
The routing suggested for cyclists is designed to avoid freeways and high-traffic areas, and to select gentler terrain by routing around hills. To make it even more useful for riders on the go, Google expects to have a mobile version available in the near future, as well.

Colorado Approves 30% by 2020 Renewable Energy Standard
Yesterday, Colorado's state legislature finalized a bill to increase the state's renewable energy standard to 30 percent by 2020.
Colorado was one of the first states to adopt a renewable energy standard at all, committing in 2004 to get 10 percent of their electricity from renewables by 2015 and increasing that to 20 percent by 2020 in 2006. This latest measure puts the state right behind California, who has the highest standard at 33 percent by 2020.
The bill also requires utilities to get 3 percent of their electricity from distributed sources like rooftop solar and other smaller wind and solar installations in order to give a boost to local renewable energy and construction companies. That requirement alone will be responsible for 1 GW of clean energy, save 6.8 billion gallons of water and reduce emissions by 30 million tons of CO2 a year.
