Comments Off on Dykstra Proposes Putting Modern Automatic Sails On Large Container Vessels

For several years now, many naval firms have proposed bringing back sails on modern ships in order to reduce fuel consumption and lower  greenhouse gas emissions . Ideas have ranged from utilizing solar sails to employing old-fashioned sheet sails. But now Dutch company Dykstra Naval Architects has put forward plans for a new concept sail-powered ship. Dubbed ‘ The Ecoliner Fair Winds ‘, the vessel has four massive “automatic” sails that use satellite-based weather data to harness the wind and calculate the most optimal route for the ship. The system could enable shipping fleets the world over to reduce the CO2 footprint of their fleet .

Comments Off on Report Shows That Protected Wilderness Areas Are Excellent Drivers for the Economy

It is true that money does not grow on trees, but it could come from people traveling to see them. A report titled “ West Is Best: How Public Lands in the West Create a Competitive Economic Advantage ,” written by Headwaters Economics this month, details how the West’s 355 million acres of parks and wilderness areas are drivers for high-wage jobs and local economies. Incredibly, in rural counties where land was under some sort of federal protection, employment increased by 345% over the past four decades. By contrast, in areas that had no protection, jobs increased by only 83%. It seems that preservation is a lucrative business.

Nissan LEAF to Power Homes in Japan

Comments Off on Nissan LEAF to Power Homes in Japan

In Japan this week, Nissan unveiled a system for using their LEAF EV to power a house during a power outage or shortage. The two-way charging device isn’t a new concept, it’s been part of the idea for EVs all along, but finally companies are producing the technology and nations are getting behind the idea of using EVs for extra power.  Denmark recently became the first country to create a program that pays EV owners for the power they feed back to the grid . The two-way system is beneficial in two ways:  it lightens the load on the grid during peak hours and helps cover power shortages and it also allows EV owners to buy their power during cheaper night hours and then use it during more expensive peak hours. The Nissan LEAF batteries can store up to 24kWh of electricity, which could power an average Japanese home for about two days.  If the system is just used during peak hours during the day though, the car would still have plenty of juice left for everyday trips. In Japan where nuclear reactors have been taken offline since the tsunami, power shortages and blackouts have become more common.  Lithium ion storage batteries are available for homeowners to use as back-up power, but if you can use your car for the same purpose, it becomes more simplified. via IT World

Eco Factor: Biogas-capable garbage trucks will be powered by waste. Using landfills to generate electricity is not a new concept for the City of Toronto. The city is now taking the energy generating capability of waste to a new level, by working on a garbage truck that can run on biogas generated from garbage

Plug-In Solar Appliance Brings Cheap Solar Power to Homes

Comments Off on Plug-In Solar Appliance Brings Cheap Solar Power to Homes

Solar power company Clarian Technologies has developed a new concept in residential solar power:  the solar appliance.  Just like a refrigerator or microwave, a homeowner can buy the Sunfish solar power system, plug it into any outdoor outlet and start feeding solar power into their home. Whereas most solar power systems require a contractor to install the module and an electrician to connect it to the electric panel through an inverter (to convert the DC power generated to AC power), Clarian says a handy homeowner can install the Sunfish themselves in about an hour. The other major bonus of such a plug-and-play-type system, is the cost.  Let’s face it, that’s the main draw.  The base model Sunfish will cost $799 with the largest running about $4,000, where a typical roof-mounted system costs a minimum of $10,000 and goes steeply up from there.

Concentrated Solar Power Isn’t Just for Deserts, It Could be for Walls Too

Comments Off on 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 .

Comments Off on 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

Comments Off on 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
