They are small and slow, but they don’t go far. Still it is an interesting development. I mean I do not see electric 707s anytime in the future, but for enthusiasts like with the ultra lights, it has to be an exciting time. Did I mention you have to have a fairly good sized body of water to take off and land?

It’s an Airplane, It’s a Jet Ski, It’s the Electric FlyNano

The newest electric airplane to make its first flight is squarely aimed at recreational fliers, even those without a pilot’s license. The FlyNano turned some heads at last year’s Aero Friedrichshafen aviation trade show in Germany thanks to its interesting design. The FlyNano is a miniature electric flying boat, making it essentially an airborne jet ski.

The original airplane was going to have a gas engine powerplant, but the Finnish company says the ever-improving electric motors and batteries means FlyNano will be an all-electric airplane moving forward.

The first flight was a very short one, just a handful of seconds. And the airplane didn’t really get out of ground effect. The wing area looks rather small for an electric airplane compared to other models we’ve seen, which tend to have the efficient, higher-aspect-ratio wings typical of sailplanes.

The designer claims a 10,000-foot ceiling for the airplane, but that might be a bit optimistic with the current setup. FlyNano says it will continue flight testing throughout the summer. We’re looking forward to seeing longer and higher flights, though the FlyNano could be fun as an aircraft designed to fly in ground effect.

The Ivanpah Solar Project Named 2012 Energy Project of the Year

April 24, 2012

Project recognized for its innovative approach, job creation and scale of clean energy production

(LOS ANGELES, Calif.) April 24, 2012 – NRG Energy, Google, BrightSource Energy and EPC partner Bechtel announced that the Ivanpah Solar Electric Generating System (Ivanpah SEGS) received the 2012 Energy Project of the Year Award by the USC CMAA Green Symposium. Ivanpah SEGS in California’s Mojave Desert is currently the world’s largest concentrating solar power (CSP) plant under construction. When completed, it will nearly double the amount of solar thermal electricity produced in the US.

“The sheer magnitude of the Ivanpah project is reinforcing California’s position as the leader of renewable energy in the United States,” said Caroline Fletcher, USC Green Symposium Co-Chair. “The project has demonstrated an innovative approach to partnerships and is significantly contributing to job creation in the region. We’re very pleased to honor this important project with our 2012 Energy Project of the Year Award.”

“Ivanpah is a flagship project, widely recognized for its environmentally-responsible design, and lauded for its role in helping to grow Southern California’s High Desert economy,” said Joe Desmond, SVP of Government Relations and Communications, BrightSource Energy. “We look forward to completing this important solar power facility and help California meet its economic and clean energy goals.”

“We are pleased to be a part of this award-winning project. The innovation applied to the engineering and construction of Ivanpah will help advance the renewable energy industry and make solar energy a viable option for more people,” said Jim Ivany, president of renewable power at Bechtel.

Largest tidal arrays in the world to be built in Scotland

15 June 12

Scotland will see the world’s largest tidal arrays constructed off its coast, as the first large-scale rollout of tidal energy generation.

A trial with one 30m turbine, the HS1000, anchored to the ocean floor in a fast-flowing channel near the Orkney Islands, raised one megawatt of electricity — enough to power around 500 homes. Now, Scottish Power is planning on building two farms of turbines off the Scottish coast.

The project at the Sound of Islay should hopefully generate 10MW, and then the later project off Duncansby Head (the most northeasterly point of Scotland) should generate around 95MW. While individual turbines have been trialled across the world, the arrays will be the largest of their kind, with local communities having their power provided by renewable tidal sources.

The turbines — built by Andritz Hydro Hammerfest, a Norwegian firm — represent a tricky engineering challenge. Considerations for wild plants and fish means that the blades can’t move too fast, and the turbines must be located in areas where there is a reliably fast current travelling at at least 2.5m/s (such as the Sound of Islay, a narrow passage between the Scottish mainland and the island of Jura).

U.S. coal use falling fast as utilities switch to gas

By Jonathan Fahey, Associated Press

NEW YORK – America is shoveling coal to the sidelines.

The fuel that powered the U.S. from the industrial revolution into the iPhone era is being pushed aside as utilities switch to cleaner and cheaper alternatives.

The share of U.S. electricity that comes from coal is forecast to fall below 40% for the year, its lowest level since World War II. Four years ago, it was 50%. By the end of this decade, it is likely to be near 30%.

“The peak has passed,” says Jone-Lin Wang, head of Global Power for the energy research firm IHS CERA.

Utilities are aggressively ditching coal in favor of natural gas, which has become cheaper as supplies grow. Natural gas has other advantages over coal: It produces far fewer emissions of toxic chemicals and gases that contribute to climate change, key attributes as tougher environmental rules go into effect.

This Piece Just Blew Me Away – Small unit nuclear power is just so wrong on so many levels

This is the Republican Corporate dreamland. Proclaiming that you are the energy source of  the future doesn’t make it so. But mix in a fair number of under educated farm people who will believe anything and Westinghouse who has everything to gain and you have a Missouri wet dream. Unfortunately this is just that, only it is a bad dream. I mean really, if we make it small and spread it around it will work better? Get out.

Breaking news: Exciting investment opportunity for Missouri announced today

Posted on April 19, 2012

On Thursday, April 19, Missouri’s energy future took a giant leap forward as investor-owned, cooperative and municipal utilities announced that they are partnering with Westinghouse Electric Company to apply to the Department of Energy’s Small Modular Reactors (SMR) investment fund for up to $452 million. The funding will support engineering, design certification and licensing for SMRs in Missouri.

This historic partnership could make Missouri a world leader in the energy sector economy.  Gov. Jay Nixon, Sen. Mike Kehoe, Rep. Jeanie Riddle, Chairman Pollock and the overwhelming majority of members of the General Assembly who support nuclear power and helped make this amazing opportunity a reality, should be applauded for their hard work and commitment to Missouri’s energy and economic future.

Over the last four years, MBEF’s supporters across the state educated the public to show that cleaner, alternative energy sources like nuclear are a path forward for Missouri. Today, we are another step closer to creating jobs, boosting our economy and securing our energy future.

This announcement could make Missouri home to an SMR component manufacturing center, engineering and design center, and training facility for engineers—establishing Missouri as a world leader and exporter in energy technology and manufacturing.  In addition to the construction of new SMRs, thousands of Missourians will be put to work because of this project.

An economic impact study about the SMR project is in process and will be made available later this spring.

The Military Sheds Its Dependence On OIL – Shouldn’t we be doing the same thing

I know this week and next week, maybe all summer, may look like a chaotic mish mash of subjects but to rejuvenate my sense of purpose I am only blogging about stuff that I find interesting today. I find the military’s attitude towards peak oil to be much more pragmatic then the capitalists they serve.

U.S. military kicks more ass by using less fossil-fuel energy

By David Roberts

This is my contribution to a dialogue on the military and clean energy being hosted by National Journal.

To understand the promise of renewable energy for the U.S. military, it helps to start as far from Washington, D.C., as possible. (This is true for most forms of understanding.) Start far from the politicians, even from the military brass, far from the rooms where big-money decisions are made, far out on the leading edge of the conflict, with a small company of Marines in Afghanistan’s Sangin River Valley

Not long ago, for a three-day mission out of a forward operating base in Afghanistan, each Marine would have humped between 20 and 35 pounds of batteries. One of the reasons Marines are so lethal in such small numbers today is that they are constantly connected by radios and computers. But radios and computers require a constant supply of batteries, brought by convoy over some of the deadliest roads on earth and then piled on the backs of Marines in highly kinetic environments.

In late 2010, India Company, from the 3rd Battalion, 5th Marine Regiment, tried something new. They packed Solar Portable Alternative Communications Energy Systems, or SPACES — flexible solar panels, 64 square inches, that weigh about 2.5 pounds each. One 1st Lieutenant from India 3/5 later boasted that his patrol shed 700 pounds.

Some Of These Energy Tips Seem Aimed At The Dim Bulbs

But then again they could be 10% of the population and the tips are supplied by Dominion. I mean really a producer advising you how to not consume. Still.

10 Tips to Save Energy and Keep Cool This Summer

  1. Raise your thermostat to 78º. This is the number one way to conserve energy.
  2. When you are away from home for more than eight hours, raise the thermostat setting and you can expect to see a 1% savings for each degree of setback. This will reduce the amount of energy used to cool your home while you’re away. You can learn more about your thermostat online by visiting the U.S. Department of Energy website.
  3. Keep shades closed when the air conditioner is on. Sunny windows account for 40 percent of unwanted heat and can make your air conditioner work two to three times harder.
  4. Check and clean filters. Cleaning and replacing air conditioning filters monthly allows the system to run more efficiently.
  5. Install ceiling fans. Don’t underestimate the importance of ceiling fans. Moving air over the body provides a cooling effect. The use of ceiling fans can mean savings of around 25% on cooling costs and can make the temperature seem 10 degrees cooler.

Building The Buildings Of The Future – No Air conditioning is a place to start

Posted on by
Reply

This is an old piece but it is still as true today as it was then. Air conditioning and by that I mean cooling air when it is hot is very expensive both financially and with regards to energy consumption.

http://www.greentechmedia.com/articles/read/buildings-without-air-conditioners-the-latest-in-energy-efficiency-5413/

Buildings Without Air Conditioners: The Latest in Energy Efficiency

Air conditioners consume an inordinate amount of power in the U.S. and they aren’t very efficiently used. To save energy, some say leave them out.

Michael Kanellos: December 22, 2008

Sometimes the most efficient air conditioning system is not having one at all.

To curb energy consumption, architects with projects in temperate cities – Seattle, Portland, San Francisco – have started to design buildings without mechanical air conditioners. These buildings will have heaters in all likelihood, but not air conditioning (see Can Greentech Make Housing Cheaper and Green Buildings No Subsidies Needed).

“There are only five days a year you need cooling in Seattle,” said Amanda Sturgeon, an architect and senior associate at the firm Perkins + Will, who recently designed a building without a mechanical conditioner.

In some cases, architects are putting in air-side economizers, i.e., computer-controlled windows that open to let in cooling breezes (see The Solar Window). The General Services Administration building in San Francisco uses openable windows on 12 of its 18 floors that let in cool breezes at night that, ideally, keep the offices cool in the daytime.  There is no mechanical cooling in the open office areas.

This shift comes courtesy of two trends. One, building developers and contractors have latched onto green buildings as an economic opportunity. Designing a building to LEED Silver or Gold standards – the environmental building standards promulgated by the U.S. Green Building Council – only adds around 2 percent to the overall cost or less, according to various contractors, architects and researchers. Designing to the LEED Platinum standard can add only 6 percent if carefully planned. The trick, say Sturgeon and others, is to exploit as many passive, design-centric techniques for scoring LEED points before moving on to the potentially more expensive, equipment-centric ones like biomass boilers or new types of lighting systems.

Smart Meters – Not as smart as you think

Those crazy Brits. Always planning their regulations in advance. Here they are rolling out smart meters left and right and no one has made a peep about regulations. I am betting that that is going to hurt in the long run.

Government to restrict sales and marketing around smart meters

Energy efficiency news – by GreenWise staff
5th April 2012
Companies are to face restrictions around how they sell and market their products and around the data they can collect about their customers when mass rollout of smart meters gets underway.

Under new guidelines proposed today by the Energy and Climate Change Minister Charles Hendry, all sales will be banned during the installation of smart meters and installers will need the permission of customers before they visit if they want to market any products to households and businesses. There will be restrictions on data energy companies and other suppliers can hold about their customers. And, in a bid to help consumers save energy and cut their bills, smart meter installers will have to provide energy efficiency advice and all households will be offered an in-home display allowing them to see what energy is being used and how much it is costing.

The Government wants 30 million homes and small businesses to have smart meters installed by 2019. Smart meters give consumers access to accurate information and mean they no longer have to rely on estimated bills. But the cost of the rollout, set to start in 2014, has been estimated at £11.7 billion and consumer groups are concerned the programme could leave consumers short-changed and their privacy undermined.
