Longterm Storage Is Not An Issue – It never has been for renewable energy

This is actually part of a lecture that I give to college students called the Myths of Global Warming. The point of it is that Global Warming is indeed happening and at an accelerated pace. The point is that there have been myths erected like barricades that defend the use of fossil fuels. Here is a high tech version.

Super Hot Salt: The Newest Energy Storage Innovation?

Policymakers and energy industry experts often talk about clean energy as though it isn’t reliable. In fact, while an MIT study recently found the existing grid would probably be up to the challenge of absorbing clean energy, intermittency does present a real challenge that renewables must address to get to high levels of penetration.

But BrightSource Energy, a major player in the market for concentrating solar power, or CSP, recently announced the installation of new thermal energy storage technology at three of its planned power plants in California. This thermal energy storage technology will go a long way toward solving the intermittency problem for concentrating solar power. BrightSource’s announcement demonstrates that we can in fact get reliable baseload power from the sun [or, even better, load-following power].

The thermal energy storage systems, built using SolarPLUS technology, work by using hundreds of parabolic mirrors to concentrate the rays of the sun on a tank of molten salts, heating the salts to several hundred degrees above the boiling point of water. The superheated salt is then stored in a giant insulated container until the power plant needs to add additional output, at which point it can use the heat stored in the molten salt to boil water to create steam to drive its turbines.

Healthcare Upheld – But that is not what I am going to post about

It has been the shipping industry’s wet dream for a hundred years, Wind Power. They dream back to the days when the only costs for shipping was the ship and port fees. I do not know if this is the system that will catch on but it is pretty cool nonetheless.

Wind-Powered Cargo Ships Make a Comeback

February 28, 2011 By

Sailing ships once carried much of the world’s cargo across the seas, until canvas sheets were replaced by low-grade “bunker” oil. Now it appears that wind power is about to make a comeback, in the form of rigid “sails” that double as solar panels. The patent-pending technology, called the Aquarius Solar and Wind Marine Power System, is being developed by a company called Eco Marine Power. The dream of a high tech, sustainable energy cargo ship has been percolating for a number of years now, but it hasn’t caught on in a big way, so let’s see if this new system is The One.

Wind Power for Cargo Ships

At first blush, wind power for today’s ultra-huge cargo ships looks like a nice idea, but just not possible. The scale alone makes it seem impractical. However, that hasn’t stopped anyone from trying. In recent years a German company has come up with a parachute-like design for cargo ships that includes sails the size of football fields, and a British company has developed a more traditionally styled, rigging-free sail system for smaller cargo ships.

Most colleges could stand to turn the energy spotlight on themselves. The University of Illinois for instance is still using a coal fired boiler from the 50s. Still this is a step in the right direction.

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).

Will We Ever Live On The Moon – Humans prepare to trash the Solar System

When I posted on the transit of Venus, I said that environmentalists are concerned about the environment and that does not end at the Earth’s atmosphere or the heliosphere of even our galaxy. Human’s track record ain’t great so far. We tend to just throw stuff out there because we can. We have fired rockets willy nilly at planets some of which landed successfully but will be on those planets forever. The ones that didn’t go so well are smashed all over the place. We trashed the moon and anyone flying by the Earth would just go EWWWWWW. Look at that mess. So now what is proposed – Mining and Manufacturing. Environmentally things we do just the bestest. This is not good. Double billing here. This guy:

Will we ever… live on the Moon?

14 June 2012

by PHIL PLAIT

Will mankind once again walk on the lunar surface? I wouldn’t even hesitate to say “yes”, because the future is long, and who in the early 1950s would have dared to predict that we would even land a craft on the Moon within 20 years? But in this case, the answer probably isn’t as interesting as the question itself – more specifically, when, and why, and how will we do it?

I can think of many possible scenarios that could lead to us colonising the Moon: an extended economic boom that allows us to fund ambitious space exploration; a breakthrough in launch costs which makes them drastically cheaper; or the discovery of some vital natural resource on the Moon. But I don’t like betting on breakthroughs.

A better question is then: “What is a likely way we’ll end up with a human presence on the Moon?” Given what we know today and extrapolating from there, I have a thought on how this could happen.

Looking into the abyss

Before we talk about settling down on our rocky neighbour, we have to ask why we should head there in the first place.

Looking back on nearly 60 years of space exploration, the answer is obvious. Satellite communication. Weather prediction. Understanding of climate change. Instantaneous broadcasting of radio and television. Global positioning technology. Detailed mapping of the Earth. Environmental monitoring. Government intelligence gathering (which has prevented far more conflict than people credit it for). Disaster warning.

The Military Understands Peak Oil And Global Warming – But conservatives not so much

Posted on by

I am only going to post a little bit of this article. This is so in part because I have serious trouble calling killers of humans environmentalists. Still the point is that if all the militaries in the world just quit using any fuel tomorrow the price of all those fuels would crash and stay very low in price for a very long time. So here is a very little bit of a very good article. I mean really anything that gets Inhofe to pound on his table is a very good thing indeed.

The Real Reason the Military is Going Green

Big Oil is a big risk for national security. Can our military—the world’s No. 1 oil guzzler—change the politics of climate change?
posted Jun 04, 2012

 

Retired Brig. Gen. Steven Anderson calls himself  “an accidental environmentalist.”

His epiphany about climate change started with a tactical problem. In 2006 and 2007, when he served as the military’s chief logistician in Iraq, he coordinated the transport of millions of gallons of fuel across the country to power everything from vehicles to the large compressors used to cool individual tents—or, as Anderson puts it, for “air conditioning the desert.” He was taking one casualty for every 24 fuel convoys, and he was doing 18 convoys a day. That’s one casualty every other day. He needed to get the trucks off the road. He needed to find a way to reduce the military’s fuel use.

The question remains, can the weight and pragmatism of military leadership sway political leaders in Washington?

“There’s a direct relationship between energy and the military. The more energy consumed, the less effective you are militarily because you’re more vulnerable,” said Anderson, who reported to General David Petraeus. “They love to take out our field trucks. They make a big boom when they do.”

Since then, Anderson, like many military leaders, has realized that guzzling oil makes the United States vulnerable in other ways. “I’m a soldier,” Anderson said. “Why should I be concerned about climate change? Climate change brings about global instability. That makes the world more vulnerable and it’s more likely that soldiers like myself will have to fight and die somewhere.”

Never mind D.C. conservatives who claim to be tough on defense and suspicious of climate science: The Department of Defense isn’t denying that climate change is a major national security threat. “The change is happening. It’s just a reality,” said retired Marine Col. Mark Mykleby, a former strategy assistant to the Joint Chiefs of Staff. “Science tells us it’s coming our way.”

My ability to post videos is limited by my technological inadequacies. However, we care about the environment exactly because we care about the solar system and the universe. So since it will not happen again in my lifetime here is a short clip of the transit of Venus across the face of the sun.

Energy Independence The Funny Way – A good time was had by all

Posted on by

Yes it is true. I am promoting a book I have never read. But you know what? I should have.

http://business-network-land.blogspot.com/2012/05/robert-danziger-funny-thing-happened-on.html

Robert Danziger: A Funny Thing Happened On The Way To Energy Independence – Author Interview

Humorist and alternative energy pioneer Robert Danziger was kind enough to take the time to answer a few questions about his hilarious memoir about his life in the world of alternative energy, A Funny Thing Happened on the Way to Energy Independence.

The author finds the humor in such widely diverse places as Cal-Tech, the Jet Propulsion Lab (JPL), and of course in his own business ventures in the alternative energy field. A true renaissance man, the author has enjoyed more careers, and indulged in more laughter, than many people would experience in two lifetimes.

Thanks to Robert Danziger for his comprehensive and informative answers.

What was the background to writing this book A Funny Thing Happened on the Way to Energy Independence?

Robert Danziger: At the gym a couple of years ago a young mother was supervising her two kids, five and eight years old. We struck up a conversation and she told me that she doesn’t let her kids watch the news anymore because the energy and environmental stories had given them repeated nightmares. Partisanship and the escalation of catastrophic rhetoric threatened the sense of security and safety she wants for her children.

My career has been inventing and developing solutions. I am fundamentally optimistic about new technology and our ability to respond to crisis. Scaring people doesn’t work and breeds resentment. I don’t want to be part of scaring kids to accomplish something.

The conversation with that young mother convinced me to take a year or so to listen to people from a broad range of ages, politics, and beliefs to try to find out what people agreed on, if anything. I found three things all of them, at least in these groups, agreed on without exception: people like to laugh; like music; and want energy independence and a clean environment when they are coupled with prosperity.

Dragon capsule on course for space station arrival

By MARCIA DUNN

The Associated Press

CAPE CANAVERAL, Fla. — The privately bankrolled Dragon capsule approached the International Space Station for a historic docking Friday after sailing through a practice rendezvous the day before.

The unmanned SpaceX Dragon was on track most of the morning to deliver a half-ton of supplies and become the first commercial vessel to visit the space station. But as the capsule drew within 100 feet, flight controllers commanded it to retreat.

The capsule backed off to 230 feet as the SpaceX company worked to resolve a problem with the on-board tracking sensors. Stray reflections from the Japanese part of the space station were interfering with the Dragon’s laser-based sensors, officials said. SpaceX mission controllers quickly fixed the trouble and resumed the docking operation.

On Thursday, the capsule came within 1½ miles of the space station in a practice fly-by. It returned to the neighborhood early Friday so Kuipers and U.S. astronaut Donald Pettit could capture it with a robot arm. First, the capsule went through a series of stop-and-go demonstrations to prove it was under good operating control.
