shared by Hans De Keulenaer on 25 May 08 - Cached
  • Some researchers are looking beyond our planet to the night sky. It turns out, there's a way that we can generate electricity from the moon -- thanks to the tides created by the gravitational pull the moon exerts on Earth's oceans. The Earth is tugged by the sun and moon. The sun dwarfs the moon in size, but the moon is much closer to Earth -- around 239,000 miles away, compared to the distance of 93 million miles between the sun and the Earth. Proximity trumps size when it comes to tidal movement here on Earth: The moon exerts more than twice as much gravitational force on Earth than the sun does

  • Researchers at the Biodesign Institute of Arizona State University have come up with an alternative way of generating electricity. In a new study featured in the journal Biotechnology and Bioengineering, lead author Andrew Kato Marcus and colleagues César Torres and Bruce RittmannThey mentioned that they are using the tiniest organisms on the planet—bacteria—for this purpose. They added that they are looking forward to commercialization of a promising microbial fuel cell (MFC) technology. The microbial fuel cell will generate electrical energy by using any kind of waste, such as sewage or pig manure.

  • But a new study by the Harvard School of Public Health could throw a wrench in that argument, by suggesting that heat waves are deadlier than cold snaps – if true, that means the winter-time benefit of a warmer planet may be more than offset by an increase in deaths in the summer.

  • ComEd, the electric service provider arm of Exelon Corporation (which delivers electricity to about 70 percent of northern Illinois), is planning a distributed solar array that will involve outfitting 100 Chicago-area homes with solar photovoltaic panels, and retrofitting at least 50 of those with “smart” meters, net metering, battery backup and a grid-tied status that enables them to send unused electricity from their solar energy systems back to the grid.The aim, according to ComEd, is to convert each home into a “mini-utility” in an attempt to prove that individual homes can act as power generators, buying and selling electricity in real-time, according to ComEd Environmental and Marketing VP, Val Jensen.

  • The issue of energy-efficiency has leaped into the public consciousness in recent years. Consumers are being bombarded with advice about the best way to save electricity, save money and save the planet.But has this onslaught of information left many members of the public sceptical about the quality of advice being given? The results of a new survey would suggest that this indeed is the case.Over 9,000 consumers in 17 countries took part in the study, conducted by Accenture, which aimed to identify the changing attitudes relating to energy-efficiency.

  • Here is the Brad Edwards interview. Dr. Edwards received his PhD in physics in 1990, and worked at Los Alamos National Lab for 11 years. After leaving Los Alamos, Dr. Edwards has dedicated his career to researching and developing the space elevator concept. All of his research indicates that the space elevator concept is valid and feasible. He currently heads a company called Black Line Ascension, which is actively promoting the space elevator concept. He has published several books on the space elevator, including The Space Elevator: A Revolutionary Earth-to-Space Transport System, and Leaving the Planet by Space Elevator.

  • n aluminum can costs about a cent. Almost worthless, so it’s easy to toss it in the trash. It's like a magic trick, if you think about it. The thousands of stages in the manufacturing process, the material costs and the human stories, disappear into the air when we only have to spend a cent.   It’s how environmental catastrophes happen. We can’t see how unsustainable some products really are - because when they come in packs of 10 for a buck, who would be crazy enough to sell our planet off so cheaply? Separating price and value requires a shift in perspective. Things are often cheap because companies have figured out ways to externalize their true costs. Here's a look at what it really takes to make 10 everyday items we all use.

  • Advocates of Planet Relief finally relented after viewers said that they wanted intelligent programmes about climate change instead of lectures from hypocritical pop stars and celebrities.
  • Peter Horrocks, head of BBC television news, added: We should be giving people information, not leading them.” The BBC has now scrapped the concept. Negative reaction to this summer’s flop Live Earth concert, promoted by Al Gore, was cited as a factor. Audience feedback found that viewers wanted serious, informed programmes about the planet’s future.

This Changes Everything: Capitalism vs the Climate review - Naomi Klein's powerful and ... - 0 views

shared by Arabica Robusta on 19 Apr 15 - No Cached
  • Much of this book is concerned with showing that powerful and well-financed rightwing thinktanks and lobby groups lie behind the denial of climate change in recent years.
  • Klein interprets the marginalisation of climate change in the political process as the result of the machinations of corporate elites. These elites “understand the real significance of climate change better than most of the ‘warmists’ in the political centre, the ones who are still insisting that the response can be gradual and painless and that we don’t need to go to war with anybody… The deniers get plenty of the details wrong… But when it comes to the scope and depth of change required to avert catastrophe, they are right on the money.”
  • Klein is a brave and passionate writer who always deserves to be heard, and this is a powerful and urgent book that anyone who cares about climate change will want to read. Yet it is hard to resist the conclusion that she shrinks from facing the true scale of the problem. When I read The Shock Doctrine (Guardian review headline: “The end of the world as we know it”), I was unconvinced that corporate and political elites understood what they were doing in promoting the wildly leveraged capitalism of that time, which was already beginning to implode. The idea that corporate elites are in charge of the world is even less convincing today. The neoliberal order has recovered, and in some countries even achieved a spurious kind of stability, but only at the cost of worsening global conflicts.

  • Another problem with pinning all the blame for climate crisis on corporate elites is that humanly caused environmental destruction long predates the rise of capitalism.
  • Though she identifies the prevailing type of capitalism as the culprit in the climate crisis, Klein doesn’t outline anything like an alternative economic system, preferring instead to focus on particular local struggles against environmental damage and exploitation. In many ways this makes sense, but in a global environment of intensifying scarcities, giving priority to local needs is unlikely to be a recipe for harmony. Whether in the Congo in the 1960s or Iraq at the present time, internecine conflicts – exploited and aggravated by the geopolitical stratagems of great powers – have led to a condition of endemic war.
  • Throughout This Changes Everything, Klein describes the climate crisis as a confrontation between capitalism and the planet. It would be more accurate to describe the crisis as a clash between the expanding demands of humankind and a finite world, but however the conflict is framed there can be no doubt who the winner will be. The Earth is vastly older and stronger than the human animal.
