The real winning "device"? Conservation land and organic farming. Mega-devices.
Prairie National Park (and windfarm). And biogas digestion to make organic fertilizer.
7 million square miles of prairie would sequester all present uS CO2. Too big?! Yes, but using organic farming and conservation land could still sequester one third. And plugin cars, wind/wave power, solar,biogas, and conservation could eliminate most of present cO2.
So the sequestration land could actually remove CO2 already in the atmosphere on a net basis.

A precursor to fuel cell/turbine aircraft engines? The turbofan engine would be part electric motor and part turbine. Also opening up the possibility of using batteries or ultracapacitors to plugin the aircraft before a flight, producing even greater mileage gains for air travel.
Battery and ultracapacitor energy storage are theoretically approaching the energy density of liquid fuel. If/when they get close enough, hybrid plugin airliners will be possible.
This backup power device pictured in the boeing article could also make any electric car a serial plugin hybrid, just what we need to halt GHG global climate disaster. But will it ever be mass produced? Not with the auto companies now in control. Too bad.

Energy storing high voltage direct current, buried or underwater power lines.

A new take on a very old technology is about to beat batteries all hollow in terms of energy storage density and cost. Its aimed at powering plugin cars. EEstore, a leading startup in this area is mysterious, but news that does leak out indicates maybe...
" EESU is projected to offer up to 10x the energy density (volumetric and gravimetric) of lead-acid batteries at the same cost. In addition, the ESU is projected to store up to 1.5 to 2.5 times the energy of Li-Ion batteries at 12 to 25% of the cost."
http://thefraserdomain.typepad.com/energy/2007/01/eestor_in_techn.html
Ben Franklin used one of the first capacitors, the leyden jar, in his lightning experimentation. The new ultracapacitors use a nanotech insulsating material between two metal sheets rolled up to boost this simple technology beyond the energy storage capability of batteriers.
My wild speculation is that the power transmission technology used right now, namely 500,000 volt direct current transmission, could be used for energy storage employing a nanotech ultracapacitor thousands of miles long that doubles as transmission line. Another beautiful aspect is that unlike alternating current transmission lines, that lose too much power to ground when buried or running underwater, direct current transmission does not have this loss problem.
It can be buried out of sight and mind of NIMBYs. Plus ( this is a big plus), it does not emit electromagnmetic radiation like alternating current transmission, no stray voltage. No problems with real or imagined health effects.
Using the principles of the basic physics of capacitors a rough estimate of storage available per mile of this proposed transmission/storage can be made. The ultracapacitor in development by EEstore is purported to have aproximately 2 times the electrical storage density of lithium ion batteries.
And the energy storage of a capacitor is directly proportional to voltage, the 500,000 volt ultracapacitor would store maybe 1000 times the power per area of metal plates rolled up into the device. but of course the insulator would need to be thicker for 500,000 volts operating voltage than 500 volts. The density would probably be 100 times the storage potential of the EEstore device, due to the much higher voltage. depending upon the performance of nanotech materials.
I'll use 100 times for this guesstimate. An EEstore electric car ultracapacitor could store around 70 kwh for the same size as the Altairnano li-ion plugin car battery. About 7 kwh per cubic foot. So I'm guessing around 500 kwh per foot of this transmission/storage line. Around 2.5 million kwh per mile. So in a thousand mile transmission loop that is 2.5 billion kwh.
The total power generation capacity of the US is around 1 billion kw. That would mean that 50 of these 1000 mile loops, one per state on average, would store enough electricity to power the US for 125 hours with no generation input. That would more than do the complete job of backing up renewables.
This is all wild speculation at this point. Any utility engineers have any critique of this analysis? Please be frank.

The interesting part about this MIT design, at least to me, is the potential to mass produce electric plugin conversions for front wheel drive internal combustion cars.
A kit could include two of these wheel/motor combinations that bolt on in place of the regular rear wheels and a charger/controller/battery pack that goes in the trunk. Quick, economical conversion of your used economy car to plugin hybrid. The first 25 miles of your drive on battery power, before you need your gasoline engine.
That's a way to convert the world's cars to plugin hybrid without the huge expense. A 5000 dollar kit would pay it's way in only a few years of gasoline savings.

I can't believe it, but thanks to Grist I am kicking the ass (rhetorically)of one of the most infamous climate disaster deniers! Robert Pielke, Jr.
Reproductive rights for women pielke? That would stop the exponential growth of human populations.
You could feed, clothe, house, and medicate everyone in poverty, but without those rights, the rise in population will make it physically impossible to continue. It's the power of compound growth.
Besides the libertarian corporate freemarketeer political faction is more interested in killing as many people in poverty with wars over oil and other resources than really helping them.
The sudden interest in the well being of those in the under developed world is really all about that infamous talking point. Your comment being simply a repitition of it. It's we environmentalists that are killing the poverty stricken by opposing unlimited growth, pollution, use of toxins like DDT, chemical agribizz, nuclear power, unregulated corporate power, genetically engineered crops, and all of your other pet causes? Right?

Anti-wind power wing nut talking point, "capacity factor".

On dealing with the "capacity factor" talking point.
This is a widely used talking point against wind power. The way to deal with it is to compare kwh produced instead of capacity factors.
There is a convenient graph on the GE wind power site that provides the necessary data.
http://www.gepower.com/prod_serv/products/wind_turbines/en/36mw/36mw_data.htm
It's the "Average energy yield: 3.6 mw" graph.
Find the average windspeed for the area. For example 8.5 m/s on an offshore platform in the gulf. That would correspond to 12 million kwh for this 3.6 mw machine.
A 1.37 mw generator operating continuously for one year (8760 hours) would produce 12 million kwh.
A source that runs for 80% of the time, like a coal or nuclear plant (they have downtime for maintenance), would have to be somewhat larger, 1.71 mw.
So to equal the annual kwh output of a standard 1000 mw coal or nuclear plant would take 585 of these 3.6 mw GE machines mounted on the offshore platforms.
1000 wind machines of this size would equal the output of 1700 mw of coal or nuclear generating capacity.
To get to the 3000 mw generating capacity that was mentioned in Laurence's link would take slightly larger wind machines than the 3.6 mw GE model. The blade diameter would need to go from the 104 meters of the 3.6 mw model to around 136 meters.
Not that diificult a task given mass production and installation.
Increasing the scale of the wind machines to around 312 meters would increase the power output to equal 25,000 mw of coal or nuclear generating capacity.
Adding wave power could double that output.
Electric power equivalent to 50 nuclear reactors or coal plants from 1000 offshore wind/wave power installations. It's sci-fi now, but it doesn't have to remain so. Communications satelites were sci-fi a few decades back too.
Hurricane protection can be obtained by mounting the wind/wave power installations on floating platforms that are submersible during severe storm conditions.
The whole electric generating capacity of the US is around 1 million mw. That would take 20,000 wind/wave power systems of the 312 meter scale.
With conservation saving 40% of current power use, plugin vehicles could be supplied as well, with that same generating capacity.
A mix of offshore wind/wave power, say 5000 installations, and large scale wind on the great plains, say 10,000 units, biogas generation from manure,waste, and garbage used in fuel cell/turbines, and solar cogeneration on every suitable roof space and over parking lots, and natural gas from coal and tar sand reserves used in the same fuel cell/turbines as the fossil fuel emergency backup of last resort.
I think it's becoming clear that this really is a practical way to go.

Check out the natural themes in these great paintings that can withstand the rigors of family footwork!
And check out this letter to the editor that the artist wrote:
A friend recently asked me, "What is it you Democrats want?" I had to stop and think a bit. "Well," I said, "to grow the Party, to elect Democrats, to reverse the course George Bush and company have led us on."
In November, I showed up at a Party function wearing a campaign pin to which I had affixed a picture of my grandson. I realized that I wasn't working for a particular candidate or party, so much as I was FIGHTING for this child, for all the generations to come, and more than that even, for this planet to which we all cling in fear and hope.
But to answer my friend, in concrete terms; this, in part, is what we want.
1) Fairness. Corporations and the wealthy should have to pay the same tax rate as the rest of us. They don't. Everyone knows this. It is inexcusable.
2) A health care system that includes everyone.
3) Energy independence. No more subsidies for oil companies. That money should go to innovation in alternative energy. Our idle factories could be producing wind and solar, and other systems, providing new technology and good jobs.
4) New thinking in education. Our kids aren't dropping out because they're stupid. It's because they don't believe in the future. Our society raises them to be mindless consumers instead of problem solvers. We need to challenge them, involve them, invite them to participate politically and otherwise. Education needs to be about ideas, innovation, meeting the challenges of an increasingly crowded and complicated world. Education needs to be RELEVANT.
5) A government of the people. At the very least, average citizens deserve representation equal to that the corporations enjoy. Until that happens, nothing will change. They will just keep getting away with it.
6) We need an acknowledgement from government and the private sector of our responsibility to the planet and all of its inhabitants. We must accept our part in the degradation of our world and join the many nations already working to make changes, and we need to influence those who are not, to begin to do so. This is not a political issue. It's a matter of survival.
7) We must demand a renewed commitment to international diplomacy. America must lead by example, not by bullying. We cannot afford the Neanderthal attitudes of the current occupants of the Whitehouse. NEVER AGAIN should we allow our brave troops, our sons and daughters, to be sent into harm's way on the basis of faulty information or downright lies.
8) After 9/11, George Bush asked us to keep shopping, keep traveling. For the challenges we face, we must ask more of ourselves and our leaders. During Word War II, the public sacrificed proudly. We need leadership that represents the best we can be. Until that happens, we will continue to be ignored and exploited by the scoundrels in Washington.
I will close with the words of Bob Marley, "Get up. Stand up. Stand up for your rights...."

"...lawmakers must also have the courage to promote safe climate-friendly nuclear energy."
Yep, that's the right word for the people who live or work near a nuclear plant. Courage!!
If there's an accident it might not be as bad as Chernobyl.
Actually a government study found that each one of over 100 "swimming pool" used nuclear fuel rod storage facilities (located at nuclear plants all over the US, some on earthquake fault lines)could release 8 to 17 times the contamination of the Chernobyl incident.
Or it might be the deadly silent (covered up by nuclear contractors/regulators)contamination in your groundwater that gets you.
Or the yellowcake dust in the air from uranium mining.
Or nuclear proliferation of weapons made possible by nuclear power plants, like those in Iran. And N Korea, and Pakistan, and on and on.
Or nuclear winter caused by nuclear weapons "exchanges" in the middle east.
Let's take the chicken's way out instead. Forget " the courage to promote safe climate-friendly nuclear energy".
Wind power, wave power, solar power, conservation, plugin vehicles.... cowardly yes. But a lot better for the planet.

7 billion tons of CO2, current US emissions
by

on Sun 04 Feb 2007 11:28 AM CST
Doom and gloom! Hard to maintain a sense of humor in the face of that figure. It would take 7 million square miles of prairie grass to sequester all that! Contrary to my optimistic estimates.
But a prairie national park and windfarm could still do the job. If plugin hybrid drivetrains took over transportation energy and conservation in the form of geothermal heat pump heating/cooling took over from standard heating and air conditioning.
Another promising source of GHG reversal is manure, sewage, garbage,and farm waste biogas digestion. It would prevent the massive amount of natural gas released by nitrogen runnoff into wetlands, rivers, and lakes. By both directly preventing the runoff and also providing organic fertilizer for farming. This would stop fossil fuel fertilizer runoff.
This whole comprehensive plan is a very tall order though. Political will to do this just does not exist at this time. I fear that only a series of natural disasters, like huge icecap melting and/or several Katrina sized hurricanes in one hurricane season would galvanize the mass media and the public into forcing politicians to actually agree to a comprehensive plan.
Right now scientists are afraid themselves. Afraid to even connect more severe storms and catastrophic ice melting with global climate change. It could very well kill their careers if they come out and tell the truth. The sad state of the IPCC report tells the tale. Intimidation and censorship have us all waiting another two years for the next report to verify what we already know.
Meanwhile the ice proceeds to melt at an exponentially increasing rate. And subsidies keep on going to fossil fuel, nuclear power, and fuel farming. With huge kickbacks to political parties to keep the status quo cash flow going.
Only two areas provide very slight hope.
First: Wind power has been given the green light from The Audobon Society (as far as danger to birds) and a recent windfarm study confirms that wind could provide most of our baseload power without a lot of expensive storage or backup power plants.
Second: there appears to be a race heating up between many automakers to produce plugin hybrid vehicles.
These provide very little hope though since the resistance to actual capital for mass production for these efforts is very strong. The really large investment funds and banks that hold very large stakes in the status quo energy systems, fossil fuel, nuclear, and now fuel farming see only financial disaster in any energy revolution.
They don't see the much larger financial disaster coming from massive global climate disaster. Bottomline corporate group think only considers the upcoming quarterly profits. So it goes. It really is a hopeless fight.
But hopeless causes are the only ones worth fightinmg for.

Aqua Teen Hunger Force

Perhaps homeland security needs to hire at least a few people who watch cartoons, maybe that would be more helpful.
These packages were attached to a bridge for WEEKS before being discovered? What does this tell US about the performance of homeland security?
Has it improved since Katrina or since that plane flew into the Manhattan building a few months ago?
How many 100 billion has Chertoff (the whitewater assistant prosecutor, great credentials to oversee homeland security?) squandered. 1.2 trillion doled out to Halliburton and friends in Iraq.
How is that going?
Better send those cartoon promotion guys to gitmo. That'll secure the homeland.
And better hope that real teens don't get the idea that pranking homeland security is just good clean (whistleblowing) fun. Exposing the sorry state of contract on america homeland security before Condi's mushroom clouds sprout.
Maybe the only way to get any of our country back from corporate kleptocracy is by waking up the public to the complete lack of any competence or honesty in the brand new homeland security agency. It's like that police "academy" in Baghdad.
http://www.washingtonpost.com/wp-dyn/content/article/2006/09/27/AR2006092702134.html
Looks good from a satellite in geostationary orbit, but on closer inspection the whole structure has been gutted by looters and is dripping sewage. And that's the police "academy"! Imagine what the rest of the Halliburton Iraq reconstruction looks like?

Good going Germans!
The demise of nuclear power is coming. The age of renewable energy is starting.
Will nuclear winter cancel civilization first? Unless US foreign policy changes immediately that is a distinct possibility.
How many think nuke-u-ler bunker busters are all locked and loaded ready to descend on Iran? Raise you hands.
How many think congress will stop them?
