From the too not-funny to be as funny as it should be dept:

Thunder-Bay-OPG-Generating-StationOntario is now the first jurisdiction in North America to fully eliminate coal as a source of electricity generation. The Thunder Bay Generating Station, Ontario’s last remaining coal-fired facility, has burned its last supply of coal. Operated by Ontario Power Generation, Thunder Bay Generating Station was the oldest coal-fired station in the province. The plant is scheduled to be converted to burn advanced biomass, a renewable fuel source.

The province has replaced coal generation with a mix of emission-free electricity sources like nuclear, waterpower, wind and solar, along with lower-emission electricity sources like natural gas and biomass. The move to bio-mass rather than to natural gas has raised concerns in Thunder Bay. NOMA and Common Voice Northwest, and the City of Thunder Bay have all expressed concerns.

P-51 Mustang, Fly Navy, Fly seawater

Tim writes: I’m not in the slightest impressed by fantasy “could”, “might”, “future”, just do it. The U.S. Naval Research Laboratory have done just that except the price for this little party trick, I hate to think.

A nice warm day! (Photo: U.S. Naval Research Laboratory) model P-51 [*]

Navies are very interested in technology where that might be a military advantage. Here I see spin as an environmental statement being put onto military interest, creating practical liquid fuel without access to land. The two stroke aero-model engine is running from feedstock extracted from seawater, plus electricity. The former is easy enough, the latter is the rub over real world usage. If you have nuclear power there is plenty of electricity.

The process is not so far from Talkshop Fossil fuels puzzle. It only needs sea-floor calcium carbonate sediment to be subduct and cooked with deep heat in the presence of catalytic iron to produce hydrocarbons, nature’s recycling.

Fossil fuels puzzle

Posted: April 12, 2014 by oldbrew in Astrophysics, Carbon cycle, Energy, Geology, Uncertainty

Do all so-called fossil fuels originate from fossils or not?
It’s a puzzle, sometimes called the abiotic (non-biological) argument.

We know there’s methane elsewhere in the solar system:

‘The presence of methane on Saturn’s moon Titan and in the atmospheres of Jupiter, Saturn, Uranus and Neptune is cited as evidence of the formation of hydrocarbons without biology, for example by Thomas Gold. (Terrestrial natural gas is composed primarily of methane). Some comets contain “massive amounts of an organic material almost identical to high grade oil shale (kerogen),” the equivalent of cubic kilometers of such mixed with other material; for instance, corresponding hydrocarbons were detected during a probe fly-by through the tail of Comet Halley in 1986.’

Duke Energy’s Clean Coal Plant Uses More Energy Than It Produces
by Paul Chesser 25-3-14

Duke-EdwardsportNLPC has detailed extensively the wastefulness and folly of spending billions of taxpayer and consumer dollars to subsidize wind energy, solar energy and electric vehicles, all in the name of fighting climate change.

But the complicated, uneconomical boondoggle that Duke Energy built inEdwardsport, Ind. so as to burn coal gas rather than coal – and thus produce less carbon dioxide than a traditional coal plant – may be the dumbest idea to fight imaginary global warming to date. If you swallow the alarmists’ premise and “solutions,” the plant so far is a joke, as recent evidence shows it is using more energy than it produces.

From the Kentucky.com website:

biomass power station.Power plants that burn wood to produce electricity emit comparatively more pollution than modern coal-fired power plants, according to a group that advocates tougher rules on the growing biomass-power industry.

The issue is relevant in Kentucky because of a proposed wood-burning power plant near Hazard, called ecoPower Generation, the state’s first.

In a study released early Wednesday, the Massachusetts-based Partnership for Policy Integrity said wood-fired plants are not as clean as advocates claim, putting more carbon dioxide and other pollutants into the atmosphere than coal or natural-gas plants when judged on the ratio of pollution to energy produced.

EU carbon plunges ahead of emissions data
Speculation EU emissions fell further than expected last year has seen the continent’s carbon price experience its biggest one day drop in a year, with the price falling more than 20 per cent to below €4, Bloomberg reports.

According to the news service, carbon futures for December fell as much as 29 per cent after Britain posted a bigger-than-expected emissions drop last week, analysts are expecting the same when EU data is released this week.
EU carbon futures had reached a 15-month high earlier in the week, Bloomberg reports, as backloading took effect.

Death Cross Mix for European Energy : No Future
by Andrew McKillop 29-03-2014

EU-sinkingPlay With the Toy Until it Breaks
Commentators have begun to focus on the “moving average” of always-unrealistic energy policy and programs in the European Union, easily finding that they signal a “bearish outlook” for future energy supply in Europe – but certainly not for energy prices.  In fact not only the poster child victim of the EU’s mix and mingle of often-extreme policies – electricity, but also increasingly gas and then oil – faces a supply outlook that almost inevitably has to be down. This is despite, or because of, ever-rising energy prices, led by electricity price rises! Prices are driven up by a death cross convergence of political, economic, financial, technical and even cultural “life style” factors. In the poster child country for European “energy transition”, German household electricity prices are around 25 euro cents per kiloWatthour in early 2014, pricing their power at an oil equivalent (1600 kWh per barrel) of around $540 per barrel equivalent. Can we be surprised that German electricity consumption is falling?

level_playing_fieldTwitter climate debate warrior ‘Ima Disbelievin‘ sent me this short article which is worth a post. It’s a followup to the Tony Thomas article a week or so back which covered the story about the American Physical Society APS reworking their position statement on climate change and global warming.

In the American Physical Science’s transcript of discussions relating to their upcoming revision of their position statement on Anthropogenic Climate Change, Dr. Collins states:

So, we build climate models. We assume when we construct those models that the net energy balance of the planet was identically zero or effectively zero at the start of industrialization.

goreballsReposted from Ukipdaily.com. The content about Enron and Gore is what caught my eye. The final paragraph is a bit of a mashup. Perhaps we could help Malcom out with a similar length statement which is a bit more rigorous.

There were three key individuals central to the advance of the Global Warming Hoax; Ken Lay of the Enron Corporation, Al Gore Vice President of the USA and his former University lecturer Professor Roger Revelle.

A former under-secretary general of the United Nations, Maurice Strong also aided the promotion of their efforts.

In 1957, Revelle suggested that the Earth’s oceans would absorb excess carbon dioxide generated by humanity at a much slower rate than previously predicted by geoscientists, thereby suggesting that human gas emissions might create a ‘greenhouse effect’ that would cause global warming over time.

Al Gore graduated from Harvard in 1969 and had been particularly impressed by Revelle’s class. From then on Al Gore was and still is, convinced of manmade global warming.
