Not much oil or gas, but plenty of steam available for use in Iceland as Phys.org reports.

It’s named after a Nordic god and drills deep into the heart of a volcano: “Thor” is a rig that symbolises Iceland’s leading-edge efforts to produce powerful clean energy.

If successful, the experimental project could produce up to 10 times more energy than an existing conventional gas or oil well, by generating electricity from the heat stored inside the earth: in this case, volcanic areas.

Launched in August last year, the drilling was completed on January 25, reaching a record-breaking depth of 4,659 metres (nearly 3 miles).At this depth, engineers hope to access hot liquids under extreme pressure and at temperatures of 427 degrees C (800 F), creating steam that turns a turbine to generate clean electricity.

Iceland’s decision to harness the heat inside the earth in a process known as geothermal energy dates back to the 1970s and the oil crisis. But the new geothermal well is expected to generate far more energy, as the extreme heat and pressure at that depth makes the water take the form of a “supercritical” fluid, which is neither gas nor liquid.

“We expect to get five to 10 times more power from the well than a conventional well today,” said Albert Albertsson, an engineer at the Icelandic energy company HS Orka, involved in the drilling project. To supply electricity and hot water to a city like Reykjavik with 212,000 inhabitants, “we would need 30-35 conventional high temperature wells” compared to only three or five supercritical wells, says Albertsson. The cost would be much less.

Scientists and the team working on the “Thor” drill project have two years to determine its success and the economic feasibility of the experiment, which is called the Iceland Deep Drilling Project (IDDP).

Iceland’s long-term goal is to reduce the country’s dependence on hydrocarbons by having all cars run on electric power.

Friday Funny: “Believe you can stop climate change and you will”

Friday Funny: “Believe you can stop climate change and you will”

From the “cats think they are psychokinetic because they sit in front of a door and will it to open, and eventually it does” department comes this inane study that says we can basically able to stop climate change via beliefs

Warwick Research: Believe you can stop climate change and you will
If we believe that we can personally help stop climate change with individual actions — such as turning the thermostat down — then we are more likely to make a difference, according to research from the University of Warwick

  • Individuals’ motivation to prevent climate change is negatively affected by climate change helplessness — belief that climate change is out of our personal control, so our actions will make no difference
  • But those who believe individual actions do make a difference are more likely to perform them — which leads to lower energy consumption
  • Public messages should focus on how we can make a personal difference to climate change, say psychologists

If we believe that we can personally help stop climate change with individual actions – such as turning the thermostat down — then we are more likely to make a difference, according to research from the University of Warwick.

Dr Jesse Preston in the Department of Psychology has demonstrated that people are often negatively affected by climate change helplessness — the belief that climate change is so massive and terrifying, as to be out of our personal control, and that our actions are too small to help.

This feeling of helplessness, however, makes people less likely to bother with individual eco-friendly actions – and actually leads to higher energy consumption.

In one study, the researchers tested a group of over two hundred people, and gave different members of the group varying messages about climate change.

Some were given a High Efficacy Climate Change message (that personal actions do make a difference in the fight against climate change); others a Helpless Climate Change message (that personal actions make no difference); and some were given no message at all.

Over the next week, the group reported whether or not they adopted behaviours to help stop climate change – such as driving less, hanging washing on the line instead of using the dryer, using less water, or turning the heating down.

The people who had received the High Efficacy Climate Change message reported 16.5% more of these behaviours than those who read a Helpless Climate Change message – and 13% more actions than the control group which received no message.

Moreover, people in the group which was told their actions couldn’t make a difference to climate change actually reported higher energy usage than before — showing how destructive a feeling of helplessness can be.

The researchers also found that a belief that personal behaviours make a difference enhances the moralisation of our actions – the notion that they are ‘good’ or ‘bad’ — and an awareness that the energy we individually consume could either prevent or cause damage to human life.

Public messages about climate change which focus on how we can help make a difference as individuals will be far more effective in encouraging people to consume less energy, according to the researchers.

Dr Preston commented:

“Often climate change messages try to persuade the public by increasing belief that climate change is real, or through fear of its dire consequences. But mere belief in climate change is not enough, and fear can backfire if we feel helpless and overwhelmed.

“It is vitally important that individuals appreciate the impact and value of their own actions for us to make a meaningful change as a whole.”

All power generation comes with risk. However, those risks are traded off against the immeasurable societal benefits provided by reliable and affordable electricity. Where the power source is wholly weather dependent – and the industry that profits from it wholly dependent upon massive and endless subsidies and, therefore, wholly unsustainable – there is nothing to … Continue reading Pilot’s Nightmare: Wind Turbines Present Clear & Present Danger For Light Aircraft

NEW YORK TIMES CAUSES HYSTERIA BY PUBLISHING ARTICLE MILDLY SCEPTICAL OF CLIMATE CHANGE

NEW YORK TIMES CAUSES HYSTERIA BY PUBLISHING ARTICLE MILDLY SCEPTICAL OF CLIMATE CHANGE

This article looks at the hysterical reaction to a mainstream USA newspaper publishing something even mildly critical of the alarmist theory of man made climate change. If you read some of the critical letters you cannot fail to see the horror of those who appear to regard climate change as a sort of religious text that simply is beyond criticism, or even mild questioning.  This is what makes the ordinary person take a closer look at what lies behind the alarmist headlines. As Shakespeare once wrote – they protest too much!
