Khunu is a start-up company that aims to be the first to bring yak wool clothing to the global market. They offer a range of athletic clothing that is made with 100% Himalayan yak wool. What are the advantages of yak wool? Khunu says that independent lab tests have shown yak wool to be 10-15% [...]

Now that the e-bike market is maturing in the U.S., I think we’ll be seeing some sophisticated electric bikes released this year. Here are three intriguing e-bikes that have become available so far:
The Eneloop E-Bike by Sanyo
Sanyo has introduced an electric bike called the Eneloop. This pedal-assist bike has a barely noticeable 250 watt motor [...]

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.

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.

Maybe you aren’t ready for a completely green wedding. However, there are some eco-friendly practices that you can easily incorporate into your special day.
Go Local
Use locally grown and seasonal flowers, wine and other foods purchased from community markets, rather than exotics shipped and grown in foreign locations. Also have your wedding locally rather than a destination wedding.
Incorporate Nature
Use live trees that can be planted later as centerpieces and other decorations. You can donate them to a local charity, school or other organization. This is much better than cut flowers that will just be tossed at the end of the night.

Simple Green Wedding Tips

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.

I’ve been testing some Looptwork products, and they are amazing. Here’s why: the company makes all their products from 100% industrial “excess” materials. That means every zipper, button and thread used in their designs was about to be thrown out. For example, the Hoptu Laptop Sleeve shown above is made with 100% upcycled nylon neoprene [...]

Warren County Kentucky is building the first net-zero energy school in the country.  Richardsville Elementary School will operate free of the grid by generating its own renewable energy, incorporating smart architectural features and a major emphasis on efficiency.

The list of features for this school is mind-boggling.  The school will have thin-film PV roof arrays, solar water heating, geothermal HVAC, insulated concrete form walls, a rainwater collection system and energy-efficient lighting.  The building is designed to take full advantage of natural light and wind for cooling. The plot of land includes a reclaimed brownfield, preserved woodland, a protected stream and bioswales.

A new report from technology research corporation iSuppli warns that we’re facing a global LED shortage in 2010.  Hooray!

Why am I cheering?  Because the reason for this shortage is a huge surge in demand for the energy-efficient lighting in the electronics industry.  Yes, it’s bad that the supply is low, but it’s great news that the use of more efficient lighting is becoming more mainstream.

The report says that demand for LEDs is expected to rise by double-digit percentages for at least the next three years.  In 2009, 63 billion units were consumed out of the 75 billion unit capacity worldwide.  The worst-case scenario is a rise in prices for mid-range and high-end computers and HDTVs because of their larger displays.

The solution is simple enough though:  increase production.  The two largest suppliers have gotten the hint — Aixtron and Veeco Instruments are doubling their production by the end of this year.

A new study from NASA’s Goddard Institute for Space Studies has identified on-road transportation as the most significant overall source contributing to global warming. Power generation, while having the greatest total impact, also includes a large number of compounds that increase cloud reflectivity and provide other effects to offset some of the warming they are responsible for.

In the study, rather than looking at specific chemicals and compounds, the range of airborne pollutants is broken down by economic sector. The study looks at the range of gases and aerosols that are released by each of 13 sectors of the economy, and finds that on-road transportation has the greatest overall effect on global warming.

“Cars, buses, and trucks release pollutants and greenhouse gases that promote warming, while emitting few aerosols that counteract it. The researchers found that the burning of household biofuels — primarily wood and animal dung for home heating and cooking — contribute the second most warming. And raising livestock, particularly methane-producing cattle, contribute the third most. On the other end of the spectrum, the industrial sector releases such a high proportion of sulfates and other cooling aerosols that it actually contributes a significant amount of cooling to the system. And biomass burning — which occurs mainly as a result of tropical forest fires, deforestation, savannah and shrub fires — emits large amounts of organic carbon particles that block solar radiation.”

The intent of this study is to make the information about climate change more accessible and understandable. “We wanted to provide the information in a way that would be more helpful for policy makers,” according to Nadine Unger, leader of the research team. “This approach will make it easier to identify sectors for which emission reductions will be most beneficial for climate and those which may produce unintended consequences.”

No one should mistake the point of this study to indicate that coal burning and other power-generation and industrial processes are benign and therefore do not need to be scaled back. Although industrial processes mitigate their adverse effects with regard to global warming, the sulfates and aerosols that are beneficial in this one manner are responsible for a range of other, negative environmental impacts.

The paper was published online on Feb. 3 by the Proceedings of the National Academy of Sciences.
