The Coming Era of Unlimited — and Free — Clean Energy

When I saw this headline in  a tweet from Daniel Pinchbeck I thought it was going to link to one of “those” blogs, but no, it’s straight from a stalwart of the mainstream media, the Washington Post, which is touting 100% solar-generated electricity meeting all our needs, sooner rather than later:

In the 1980s, leading consultants were skeptical about cellular phones.  McKinsey & Company noted that the handsets were heavy, batteries didn’t last long, coverage was patchy, and the cost per minute was exorbitant.  It predicted that in 20 years the total market size would be about 900,000 units, and advised AT&T to pull out.  McKinsey was wrong, of course.  There were more than 100 million cellular phones in use in 2000; there are billions now.  Costs have fallen so far that even the poor — all over world — can afford a cellular phone.

The experts are saying the same about solar energy now.

The DanTysk Offshore Wind Power Project

We managed to piss some of you off with a sponsored post from Shell, so we killed that and commit to you that we won’t take sponsored posts from oil and gas companies again. In return, please like this one about The DanTysk wind power plant, which will generate 1.3 billion kWh of clean electricity for Munich.

Why We Must Divest From Fossil Fuels: A Student’s Open Letter to Harvard President Drew Faust

Wen Stephenson and Benjamin Franta, via the Nation:

The movement for fossil-fuel divestment has swelled to what an Oxford University study calls the fastest-growing divestment movement in history, one with the potential to shift the political ground beneath the fossil-fuel lobby’s feet. There are more than 500 campaigns globally—including on some 400 college and university campuses in the United States, along with city and state governments and major religious institutions. Ten colleges and more than twenty cities—including Seattle, San Francisco and, as it happens, Cambridge, Massachusetts—have committed to divest.

Back in October, Harvard University President and distinguished American historian Drew Gilpin Faust, having faced more than a year of increasing calls by students, faculty and almuni to divest from fossil fuels, released a statement in which she explained why Harvard would do no such thing, at least not on her watch. Reactions to her position—by critics ranging from climate activist Tim DeChristopher (now at Harvard Divinity School) and Columbia’s Todd Gitlin (an alum) to former Oberlin president and National Science Board member James Lawrence Powell, among others—pointed to its logical inconsistency, not to mention blindness to moral, political and economic facts.

World’s First Magma-Enhanced Geothermal System Created in Iceland

Via ScienceDaily:

In 2009, a borehole drilled at Krafla, northeast Iceland, as part of the Icelandic Deep Drilling Project (IDDP), unexpectedly penetrated into magma (molten rock) at only 2100 meters depth, with a temperature of 900-1000 C. The borehole, IDDP-1, was the first in a series of wells being drilled by the IDDP in Iceland in the search for high-temperature geothermal resources.

The January 2014 issue of the international journal Geothermics is dedicated to scientific and engineering results arising from that unusual occurrence. This issue is edited by Wilfred Elders, a professor emeritus of geology at the University of California, Riverside, who also co-authored three of the research papers in the special issue with Icelandic colleagues.

“Drilling into magma is a very rare occurrence anywhere in the world and this is only the second known instance, the first one, in 2007, being in Hawaii,” Elders said.

Big Oil’s Big Lies

Burning gas from Deepwater Horizon oil spill 2010-05-16Antonia  Juhasz calls foul on BP and other oil giants’ claims to be supporting alternative energy, at Rolling Stone:

Since the Gulf oil disaster in 2010, BP has spent hundreds of millions of ad dollars to cleanse its image as a dirty-energy giant. In the company’s latest TV ad, wind turbines whirl in the sun as a voiceover touts the number of American jobs created by BP and promises, “We’re working to fuel America for generations to come.” There’s just one problem: BP’s commitment to wind energy is virtually nonexistent.

In April, BP announced that it is selling off its entire $3.1 billion U.S. wind energy business – including 16 farms spread across nine states – as “part of a continuing effort to become a more focused oil and gas company,” according to a company spokesperson. Indeed, though it famously rebranded itself “Beyond Petroleum” in 2000, BP also exited the solar energy business back in 2011.

Artificial Photosynthesis System as Efficient as Plants and Can Reduce CO2 Levels


Via DigInfo TV

A group at Panasonic has developed the Artificial Photosynthesis System, which produces organic materials with a world-leading efficiency in terms of solar energy conversion. The recently achieved efficiency, 0.2%, is on a par with that for real plants used in biomass energy.

Artificial photosynthesis is a technology that uses sunlight to produce oxygen and organic substances from water and carbon dioxide, like plants do. As an ideal technology that could solve both global warming and energy issues, artificial photosynthesis is currently being researched worldwide.

World’s First Perpetual Motion Machine?

via Astounde
Since at least the 12th century, man has sought to create a perpetual motion machine; a device that would continue working indefinitely without any external source of energy. A large scientific contingent thinks such a device would violate the laws of thermodynamics, and is thus impossible. Could it be that as a race, we don’t fully understand the laws of physics and such a device may indeed be possible? What would the ramifications be if we could actually build a perpetually moving device?
Norwegian artist and mathematician Reidar Finsrud is an outside the box thinker that has devised a machine that he believes achieves true perpetual motion. Take a look at the video below and see what you think.
