The recent news that the demand for coal is climbing rapidly around the world has left many of us deeply unsettled. And a new study from Australian energy consultancy ACIL Talisman doesn’t make things sound any more cheery.

The company believes that clean coal technologies such as carbon capture and storage are unlikely to be commercially available before 2020 unless major technological breakthroughs occur in the very near future.

However, the firm predicts that both geothermal and concentrated solar will be in widespread commercial use by the 2020 target date. But none of these technologies can squelch the CO2 coming from the 40% increase in coal consumption expected by 2030.

Coal power plants can utilize solar to produce 15%-60% of the electricity. A higher quantity is possible, but requires significantly more modifications to be made to the coal boilers.

Solar Interface

Mirrors, called fresnal reflectors capture the sun’s rays and heat water in the tube above. Steam lines deliver the solar energy to the adjacent coal power plant where existing coal turbines are used to produce an electric current.

The ideal situation for retrofitting a coal power plant with solar includes:

Australia’s Commonwealth Science and Research Organization (CSIRO) reports that lignocellulose, a component of plants and wood, could potentially be used as a cheap fuel—as inexpensive as $40-60 a barrel.

Even better, lignocellulose biofuels are compatible with current facilities. All they need for conversion is an extra unit in front of any existing sugar biofuel facility.

Making a mistake isn’t necessarily stupid, but making the same mistake twice is. Thankfully Australia has learned from its past and banned the introduction of Savannah cats, a natural destroyer of the country’s unique wildlife.

The humble ‘moggy’ or domestic cat maybe a cute little family pet to those in the rest of the world but to Australia’s wildlife it is a born killing machine. And once the cats have adapted to life in the wild they are even more devastating.

And the breakthrough component in their design comes from Goretex, a popular outdoor and sporting clothing brand.

Applied to the layer of breathable fabric that Monash University’s Dr Bjorn Winther-Jensen says has revolutionized the outdoor clothing industry, is a newly designed and tested air-electrode that acts as both the fuel cell electrode, and catalyst. The layer is applied at just 0.4 of a micron in thickness, which measures out to be about 100 times thinner than a human hair.

The team is part of a joint initiative of University of Stellenbosch and the Danish biotechnology firm, Aresa, which has developed the “RedDetect” bio-sensor technology in a weed called Thales Cress.

The weed changes color from green to autumnal red when it detects nitrogen dioxide leaching from mines buried in the soil.

Because the weed is too small to be seen from a safe distance, the scientists went looking for a more viable alternative, and landed on the tobacco plant, which grows easily in most parts of the world, with a little help from genetic engineering.

The key note speaker for the event, Moodie showcased the results of his study (pdf) which, amongst other things, saw that cycling currently saves an estimated $227.2 million per year in health costs alone. Dr. Moodie sayd that “this report demonstrates the considerable benefit offered to individuals and governments by cycling. Addressing the barriers preventing more Australians from cycling will deliver substantial savings to both government and the community”.

According to UNESCO, globally there are 262 international river basins: 59 in Africa, 52 in Asia, 73 in Europe, 61 in Latin America and the Caribbean and 17 in North America — overall, 145 countries have territories that include at least one shared river basin.

UNESCO states that between 1948 and 1999, there have been 1,831 “international interactions” recorded, including 507 conflicts, 96 neutral or non-significant events and, most importantly, 1,228 instances of cooperation around water-related issues.

As a result, some experts argue that the idea of water wars is rather farfetched given the precedent of water cooperation that has been exhibited by many of the countries around the world.

“Despite the potential problem, history has demonstrated that cooperation, rather than conflict, is likely in shared basins,” says UNESCO.

The report forecasted heat waves, less rain and a subsequent increased drought. It predicted that exceptionally hot years, which had originally only occurred every 20 to 25 years, were now more likely to hit every one or two years. And the report noted that all of this could start as soon as 2010.

Instead of acting upon it or even printing copies to president George Bush and his handlers, they tossed it in a cyber trash bin called Spam folder as if that was the only green thing to do.

Many months after Scott McClellan quit spinning for Dubya, climate watchers are crying foul that he never ever touched the seemingly hot subject in his recently released book, What Happened. But in his famous spins, he had blamed human activity - you and me - as responsible for global warming on more than one occasion.

Spin can be clever tomfoolery sometimes but the White House stance on global warming is well known and George W. Bush has never disappointed with his public statements that smack verily of official ignorance or pretense on the subject as an inconvenient truth.

Revetec, a little known company from the Gold Coast region of Australia, may be on to something huge: they’ve created an engine that is 50% smaller, 50% lighter, has 50% lower emissions and is cheaper to manufacture than a conventional internal combustion engine of the same horsepower. Oh yeah, did I mention that it doubles the fuel economy too.

What that means is a car like the 2007 Toyota Yaris, which is rated at 40 mpg on the highway, would get 80 mpg with a Revetec engine.

This isn’t some hoax… They have a prototype which has been attached to an actual vehicle and independently tested to substantiate their claims.

Some members of the Australian community went into paroxysm when our muddle-headed environment minister toyed with the idea of charging a modest fee for plastic disposable shopping bags that are ordinarily handed out free.

The plastic charge

Being and free and plastic is of course a lethal cocktail as far as nature is concerned. There are roughly 6 billion plastic bags used each year in Australia and this end up clogging up land fill sites or stuck in the throats of hapless aquatic life form, normally the very endangered.

Those against the move argued that people would struggle to get their shopping home, and that a large percentage of the replacement bags that customers used would be made of plastic anyway. It was also argued that the old free shopping bags were great as garbage bin liners and if they were not available then alternative bags, again plastic, would have to be purchased for the purpose.

Though many states and localities are waking up to their water shortages and taking steps to plan for “peak water”, people generally continue to waste water and to ignore the energy-water link. In 2004 the Natural Resources Defense Council did a study in conjunction with the Pacific Institute called “Energy Down the Drain” on how saving water saves energy. We need to do more to spread the word. Here are seven ways to save energy by saving water:

1. Use local water.

Transporting water uses energy, so rainwater harvesting is a serious water-and-energy saver. According to the NRDC/Pacific Institute study “California’s State Water Project (SWP), which transports water from Northern California to Southern California is the state’s largest single energy user, consuming 2 to 3 percent of all electricity. It takes tremendous amounts of energy to pump the water 2,000 feet over the Tehachapi Mountains — the highest water lift of any water system in the world

2. Use less heated water in homes and businesses.

Heating water uses a great deal of energy. Small things magnified a million times over — like washing clothes with cold water or taking shorter showers — saves large amounts of energy.

3. Use energy-saving appliances.

Energy Star appliances will decrease water and energy use.

4. Learn from Australia.

Why reinvent the wheel? Since 2006, when the BBC reported Australia’s biggest drought in 1,000 years, the situation has not improved. In an island nation, this has a tendency to focus the mind, and water-and energy-saving inventions have been pouring forth from that country, while the government introduces policies that save energy and water almost daily.

5. Rethink your bathroom.

Toto, an innovative company from Japan (another island nation concerned about water use) offers an EcoPower hands-free faucet that recharges itself each time it is used.

6. Rip out that lawn and replace it with a rain garden.

Watering grass, fertilizing it with petroleum-based fertilizers, and mowing it with a gas or electric mower…..need I say more?

7. Eat more vegetables and grains; cut down on the beef.

Animal farming takes more energy and water. “Beef production requires large volumes of water–as much as 100 times that required to produce equivalent amounts of protein energy from grains.” (Environmental Health Perspectives, 2002 And the cows are fed from corn that is farmed using energy-hogging fertilizers, insecticides, and fossil fuels.

If you think about it, it’s impossible to separate our energy use from our water use. If we can start thinking holistically about the systems we use in our daily lives — and get our governments to create policies that promote wise use of energy and water, we’ll be more ready for the limits to resources that are only going to increase.

Despite more evidence that cycling is universally good, this time in the form of a report showing that it saves the government $227.2 million in annual health costs, there is still no denying there is just one king on the Australian roads—the car!

The fact that the bureaucrats actually have to commission a report into the health benefits of cycling probably tells you exactly what you need to know about the way that Australian governments treat the activity. Does any one really doubt that cycling is healthy? And what do they intend to do with this number now that hey have it?
