Cool Earth Solar: pursuing a viable alternative to fossil fuels
Image Gallery (3 images)
There is no doubt that mankind stands at a pivotal point in our history in relation to our consumption of global resources and the resultant impact on the planet on which we live. By far the biggest concern is our ever-growing appetite for energy to power the lifestyles we have grown not only accustomed to, but also dependent upon. Solar is one answer with great potential, but economics and the amount of power it can produce in comparison to fossil fuel power stations has held it back so far. Now new approaches like Cool Earth’s collectors are becoming advanced enough to effectively tackle these problems with technology that relies on inexpensive and free materials, is scalable, able to compete economically with fossil fuel power plants and is capable of delivering not just megawatts, but gigawatts of clean power.

Energy Island: unlocking the potential of the ocean as a renewable power source
Image Gallery (5 images)
January 29, 2008 Ocean Thermal Energy Conversion uses the temperature difference between surface and deep-sea water to generate electricity – and though it has an efficiency of just 1-3% - researchers believe an OTEC power plant could deliver up to 250MW of clean power, equivalent to one eighth of a large nuclear power plant, or one quarter of an average fossil fuel power plant. Architect and engineer Dominic Michaelis and his son Alex, along with Trevor Cooper-Chadwick of Southampton University are developing the concept with plans of putting the theory to the test on an unprecedented scale by building a floating, hexagonal Energy Island that will harness energy from OTEC, as well as from winds, sea currents, waves, and the sun.

High-tech sails to benefit commercial shipping
Image Gallery (46 images)
July 5, 2007 UPDATED IMAGES For four hundred years majestic tall ships ruled the world’s oceans carrying cargo and migrants to far corners of the globe, but the advent of steam power in the late 19th century brought the golden age of sail to an end and rendered wind-powered vessels obsolete – but did it? Recent projects in both Europe and the U.S are seeking to breathe new life into this “old technology” and once again give sail-power a viable role in commercial shipping. The new era of sail-power wont see the return of square rigged barques or clipper ships, but rather the introduction of high-tech kite sails that generate greater propulsion power than conventional sails. These can be used to supplement the propulsion systems of all kinds of cargo vessels and in the process generate economic benefit, reduce reliance on fossil fuels and deliver emission reductions in a sector that has become one of the world’s biggest polluters.

The high-rise future of food production
Image Gallery (7 images)
June 26, 2007 Would you have ever thought it conceivable to grow vast amounts of produce in the heart of densely populated cities such as Hong Kong, Tokyo or New Delhi? A new model for agriculture is proposing just that. Vertical farming is the latest concept to address the impending crisis in world food production and follows the same methodology that town planners have used for years to cope with growing populations and space limitations; build up, not out. Aiming to bring food production to the places where most of the consumption occurs, the concept envisages specially designed skyscrapers that contain multiple levels of viable farmland providing all-year-round food production in a controlled, parasite-free environment.

Climate catastrophes in the Solar System
Image Gallery (3 images)
April 27, 2007 Earth sits between two worlds that have been devastated by climate catastrophes. In the effort to combat global warming, our neighbours can provide valuable insights into the way climate catastrophes affect planets. From what scientists know now, it is possible that Venus and Mars started out a lot like Earth. At some point in time, each planet followed a path that changed its climate. The transition was from Earth-like to either a cloudy inferno (Venus) or a frigid desert (Mars). Data from Venus Express and Mars express is now helping scientists determine if, when and why each planet passed the point of no-return.
The US$25 Million Virgin Earth Challenge
Image Gallery (3 images)
February 13, 2007 Sir Richard Branson’s US$25 Million Virgin Earth Challenge focuses on the biggest single problem faced by humanity today - global warming. It steps across the national boundaries which have prevented anyone a full appreciation of the damage we have done to the environment and the gravity of the consequences of messing with the planet’s ecosystem. There may not be a single effective solution to this problem but if there is, the Virgin Earth Challenge is the best chance we can see of finding it. Given that these is no effective common approach on the horizon to a potential extinction event, we applaud the initiative wholeheartedly. The Virgin Earth Challenge will award US$25 million to the individual or group who are able to demonstrate a commercially viable design which will result in the net removal of anthropogenic, atmospheric greenhouse gases each year for at least ten years without countervailing harmful effects. This removal must have long term effects and contribute materially to the stability of the Earth’s climate. Read More
How far below sea level will your home be if …
Image Gallery (2 images)
September 26, 2006 Last week we reported on the rapid and dramatic melting of the arctic icecap, and joked that the upside was perhaps that the property you bought with ocean views might soon become beachfront. Now some people might think it’s a good thing to plan for rising sea levels given that people have long been predicting that global warming will result in thermal expansion of the ocean and melting glaciers and ice sheets. In 1995 a report from the International Panel on Climate Change estimated that the sea will rise 50 centimeters (20 inches) with lowest range at 15 centimeters (6 inches) and high range at 95 centimeters (37 inches) by 2100, and NASA's take is supported with lots of evidence the warming is accelerating (temperature trends, sea level trends ) might come at us in a rush. If you go here, you can dial in the rise in water levels and see which properties will be waterfront if that occurs. Read More
