My mind is blown. My eyes disbelieve. My ears thunder. I smell a rat and I tingle in my toes. I am happy that school children will ride buses past the failed energy generator of the past and the successful energy generator of the future.

This Huge Wind Turbine Floating on Water Is Fukushima’s Energy Solution

A mere 12 miles from the wrecked Fukushima Daiichi nuclear plant will soon sit a 620-foot, 1,500-ton windmill atop a 5,000-ton podium. It’ll be the biggest floating wind turbine on Earth, and it could usher in a new age of green energy for a region largely fed up with nuclear energy.

The turbine, completed Monday, will generate up to 7 megawatts of electricity, making it Japan’s most powerful wind turbine, and the most powerful floating turbine in the world. That’s good news for Japan, a country that’s shut down nuclear power plants in the wake of the 2011 earthquake and tsunami and subsequent meltdown.

The beast of a turbine sports three 270-foot-long blades and is built to stand against winds nearly 200 mph. It’ll be part of a wind farm that will include three turbines total, and will be stationed in the Pacific in the coming months. One is already in place in the ocean—that smaller one generates 2 megawatts of electricity.

The $401 million Fukushima wind farm project is a government-sponsored collaboration among 11 companies and research orgs, like Mitsubishi, Hitachi, and the University of Tokyo.

Nuclear Power Is Dangerous – I do not think I can say that often enough

From Three Mile Island, to Chernobyl, to Fukushima, nuclear power has soaked up trillions of $$$ and awarded planet Earth with poisonous outputs  and death and destruction. The proponents point to the trillions of kilowatts generated without carbon emissions. The bottom line is what to we do to shut them down? Safely. The answer is – there is none. So we are in jeopardy for thousands of years.

No One Knows What to Do With Fukushima’s Endless Tanks of Radioactive Water

Posted By Eliza Strickland on Jun 09, 2015

This is what passes for good news from Fukushima Daiichi,  the Japanese nuclear power plant devastated by meltdowns and explosions after a cataclysmic earthquake and tsunami in 2011: By the end of last month, workers had succeeded in filtering most of the 620,000 tons of toxic water stored at the site, removing almost all of the radioactive materials.

After numerous false starts and technical glitches, most of the stored water has been run through filtration systems to remove dangerous strontium-90, as well as many other radionuclides. TEPCO, the Japanese utility that operates the power plant, trumpeted the achievement: “This is a significant milestone for improving the environment for our surrounding communities and for our workers,” said Naohiro Masuda, TEPCO’s chief decommissioning officer, in a press release.

But it’s not quite so easy to bounce back from a nuclear disaster of this scale. For one thing, don’t take TEPCO’s statement too literally: No one is living in the “surrounding communities”—they’re far too contaminated for human habitation. Furthermore, the filtered water is still full of tritium, a radioactive version of hydrogen. (When two neutrons are added to the element, it becomes unstable, prone to emitting electrons.) Tritium bonds with oxygen just like normal hydrogen does, to produce radioactive “tritiated water.” It’s impractical—or at least extremely difficult and expensive—to separate tritiated water from normal water.

2014 hot topics in renewables

January 14, 2014 | By

excerpt on solar…

The year 2013 was one for the record books for solar. According to the Solar Energy Industries Association (SEIA), the third quarter of 2013 was the second largest for the U.S. solar industry, and new solar electric capacity added in 2014 will generate enough clean energy to power more than 850,000 average American homes.

Solar became one of the leading sources of new generation in 2013 with the continued decline in equipment costs

“[This gives] the industry the opportunity to focus on soft cost reduction as well,” said Tom Solazzo, principal, PwC Power & Utilities. “Initial efforts at addressing permitting, labor, financing, and contract costs through operational efficiency and standardization are bearing fruit, with more upside potential in the future.”

First Offshore Wind Farm In The U.S. Kicks Off Construction

by Katie Valentine Posted on

Offshore wind is coming to the United States.

Construction on what will be the country’s first offshore wind farm started Monday in Rhode Island. The wind farm, which is being developed by Deepwater Wind, will be located off of the coast of Block Island, a small island about 13 miles south of Rhode Island. Once completed, the five-turbine, 30-megawatt wind farm will produce enough energy to power all homes and businesses on Block Island, which previously relied on diesel generators, according to the Sierra Club. The wind farm will also send energy to mainland Rhode Island. It’s expected to come online in fall 2016.

Environmental groups, many of which have pushed for the project since it started going through hearings in 2013, applauded the start of construction. Bruce Nilles, senior campaign director for the Sierra Club’s Beyond Coal Campaign, told ThinkProgress that the start of construction was a “landmark” moment for the U.S. wind industry, and that it “really makes real the promise offshore wind has” in the U.S., particularly on the East Coast.

 “This is technology that will play a very important part in decarbonizing electric sector,” he said.

When I first saw this I thought it was from The Onion. But this for real.

Discarded Laptop Batteries Keep the Lights On

Millions of batteries discarded with computers have more than enough life to power home lighting for one year, researchers in India say.

Many of the estimated 50 million lithium-ion laptop batteries discarded every year could provide electricity storage sufficient to light homes in poor countries, researchers at IBM say.

In work being aired this week at a conference in San Jose, researchers at IBM Research India in Bangalore found that at least 70 percent of all discarded batteries have enough life left to power an LED light at least four hours a day for a year.

While it’s possible to combine LED lights with solar panels and rechargeable batteries (see “Innovators Under 35: Evans Wadongo”), using discarded batteries could make the approach far cheaper.

“The most costly component in these systems is often the battery,” says Vikas Chandan, a research scientist at the lab’s Smarter Energy Group, who led the project. “In this case, the most expensive part of your storage solution is coming from trash.”

Solar Power Sees Unprecedented Boom in U.S.

Photovoltaics and solar thermal both enjoyed banner years, despite uncertainties
March 10, 2015 |By Daniel Cusick and ClimateWire

U.S. solar power grew by 6.2 gigawatts in 2014, a 30 percent increase over the previous year and representing nearly $18 billion in new investment, according to data released this morning by the Solar Energy Industries Association and GTM Research.

The new power systems, comprising tens of thousands of photovoltaic (PV) arrays for homes, schools, businesses and utilities, as well as a handful of large concentrated solar power facilities in places like the Mojave Desert, raised the United States’ profile as one of the world’s leading adopters of solar power, officials said.

But the future for U.S. solar isn’t without its bumps.

New installations of nonresidential solar panels, while accounting for more than 1 GW of power, shrank by 6 percent year over year, a condition caused by a variety of factors “ranging from tight economics to difficulty financing small commercial installations,” GTM analysts said in their latest “U.S. Solar Market Insight Report.”

Going To Mars – Why it will never happen

Posted on by

So see if you can follow me on this. Some people see “space travel” as a way to get off this planet. But why would you want to do that? It is a perfectly good planet. I think it is because everyone knows deep down that the way we are treating this planet may ultimately cause its demise. That is why I am ultimately an environmentalist; because I do not believe we can get off this planet. So we humans better change our ways. Why do I believe there will be no space travel for humans. The radiation levels of outer space are too great, the distances too far, and the physical demands too great. Thus I believe in saving energy and creating green energy because I believe it is the only way for our planet to survive. Yet people dream.

Breakthrough in energy harvesting could power life on Mars

Martian colonists could use an innovative new technique to harvest energy from carbon dioxide thanks to research pioneered at Northumbria University, Newcastle.  The technique, which has been proven for the first time by researchers at Northumbria, has been published in the prestigious journal Nature Communications.

The research proposes a new kind of engine for producing energy based on the Leidenfrost effect – a phenomenon which happens when a liquid comes into near contact with a surface much hotter than its boiling point. This effect is commonly seen in the way water appears to skitter across the surface of a hot pan, but it also applies to solid carbon dioxide, commonly known as dry ice. Blocks of dry ice are able to levitate above hot surfaces protected by a barrier of evaporated gas vapour. Northumbria’s research proposes using the vapour created by this effect to power an engine. This is the first time the Leidenfrost effect has been adapted as a way of harvesting energy.

The technique has exciting implications for working in extreme and alien environments, such as , where it could be used to make long-term exploration and colonisation sustainable by using naturally occurring solid as a resource rather than a waste product. If this could be realized, then future missions to Mars, such as those in the news recently, may not need to be ‘one-way’ after all.

The Foodbank Goes Green
One of the first 50 wells being drilled in October2014.
This fall work began on an estimated $850,000 geothermal
project that will help cut utility costs at the Foodbank’s 56,000 square
foot facility. The geothermal projectwill help heat and cool a portion of
the building.
50 wells were dug 200 feet deep in the open lawn on the east
side of the Foodbank’s Cook Street location to install a closed loop
geothermal heating and cooling system in the ground.
The system will use the earth as a heat source in the winter and
a heat sink in the summer, resulting in significantly lower energy
consumption.

When I Was Growing Up The Hot Things Were Compact Flourescents

Now the hottest things in the energy conservation world  or at least in the lighting world are LED lights. They come in all shapes and sizes. In fact I have one that I use as a flashlight, but it was intended to be a safety head light for my bicycle. It has been amazingly helpful. This is a complex subject so it will take me a few weeks to get it all posted. But here is a start.

http://en.wikipedia.org/wiki/Light-emitting_diode

Light-emitting diode

From Wikipedia, the free encyclopedia

 

A light-emitting diode (LED) is a two-lead semiconductor light source. It is a pn-junction diode, which emits light when activated.[6] When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.

An LED is often small in area (less than 1 mm2) and integrated optical components may be used to shape its radiation pattern.[7]

Appearing as practical electronic components in 1962,[8] the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.

Early LEDs were often used as indicator lamps for electronic devices, replacing small incandescent bulbs. They were soon packaged into numeric readouts in the form of seven-segment displays, and were commonly seen in digital clocks.

Recent developments in LEDs permit them to be used in environmental and task lighting. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching. Light-emitting diodes are now used in applications as diverse as aviation lighting, automotive headlamps, advertising, general lighting, traffic signals, and camera flashes. However, LEDs powerful enough for room lighting are still relatively expensive, and require more precise current and heat management than compact fluorescent lamp sources of comparable output.

LEDs have allowed new text, video displays, and sensors to be developed, while their high switching rates are also useful in advanced communications technology.
