Solar powered traffic light conceptualized in China
Image source: ecofriend.org
The advent of solar panels gave way to several innovative ideas on how to utilize solar energy for contemporary use. Chinese designers Cheng-Tsung Feng, Yao-Chieh Lin and Bo-Jin Wang have conceptualized a solar-powered traffic light. Instead of the usual three-tiered design, they proposed a single unit that will switch from red to amber then green with the use of light-emitting diodes or LED technology and its power source would be from solar panels attached to its hood. The idea seems quite practical considering that most traffic lights are already exposed to the heat of the sun during daytime. Read the full article here

New eco podcast: Growth – do we need it?
Here is the new environmentally friendly podcast from Lloyd & Land to tantalize your eardrums and make your eye’s mist up from wistful memories of days gone by, before growth grew and noise pollution didn’t include so many bloody blips and bleeps. The journey from Toughskins jeans and wholemeal doorsteps to Starbucks and Easter baskets full of iPods has been a road paved with consumable goods, chain stores and longer work weeks. Saci Lloyd and Graham Land discuss the disconnect between...
Strange Creatures Abound in the Ocean Deep
Lurking in the pitch black ocean depths are 17,650 species that remained unknown ‘til recent years. Approximately 3 miles (5 km) below the ocean surface, these awesome creatures were discovered through cameras, sonar and other technologies. What kinds of creatures live in such places? Rather odd ones, that’s for certain. Take the Jumbo Dumbo: a primitive finned octopod named for the large Dumbo-ear-like fins they use to swim. This particular octopod is one of the largest of its kind, measuring at...
The biofuels controversy continues: should we get off the bandwagon?
“One groundbreaking new study in Science concluded that when this deforestation effect is taken into account, corn ethanol and soy biodiesel produce about twice the emissions of gasoline.” - Michael Grunwald, Time I recently wrote an article about Indonesia’s bad biofuel industry, which is based on palm oil, resulting in mass deforestation via intense CO₂ producing slash and burn methods. One of the main problems was not Indonesia’s environmental policy per se, but that the laws are nowhere near being sufficiently...
Northeast States Sow the Seeds of Offshore Wind Farming
Hurricane winds along the U.S. Atlantic coast may finally prove to be useful. Northeastern states—ranging from New Jersey to Maine—are collaborating on starting the nation’s first offshore wind farm. Trying to become more independent from the use of energy from the Midwest, the eastern states are rushing to get this giant project up and running. Initially, the states were working on their own, individual projects; but now they see that combining their efforts and resources will have a much greater advantage...
Growing consumption and population = ‘ecological debt’
Despite growing environmental awareness and energy efficiency measures, the developed world consumes more than ever. At the same time people in China and much of the developing world are adopting more energy intensive lifestyles. So more cars and meat consumption in China, etc., combined a growing obsession for the latest consumable goods – like phones, cars and computers – in rich nations, means the world will enter into ecological debt one month earlier this year. According to the New Economics Foundation...
Guy gets 15 months in prison for dumping over 1m tires
Sometimes you just don’t know whether to laugh or cry. I must confess I did the latter when reading about the arch eco-criminal, über litter bug a.k.a. audacious tire thug who illegally dumped over a million tires in remote spots of English countryside during the course of a single year. It’s a lousy, shameless crime, but it’s also funny. I mean, was he going for a world record in tire dumping, or as the English say ‘tyre rubbishing’? And he’s been given...
China and Pakistan: More dramatic videos of Asia’s extreme weather woes

From ITN News: ‘Train ripped apart on collapsed bridge in china’ Jaw dropping footage from when a passenger train split in half on a bridge which collapsed in the China floods. From Al Jazeera English: ‘Fortitude amid Pakistan disaster’ The floods that have ravaged Pakistan have forced millions of people to flee their homes and villages, but a small number stubbornly refused to leave their homes despite the...
A New Way for college students to get around
There are two types of drivers: drivers who need a car every day and drivers who just need one for the occasional meeting or trip out of town. The automotive industry is changing, and with it, so are drivers who are now looking to save money on gas and reduce emissions. This is where the idea of car sharing comes in to play. Car sharing is pretty simple, instead of having many drivers who don’t use their car every day, these...
The hitch between solar projects and water conservation
The continued quest for renewable energy sources through solar farms has posed another glitch because it consumes huge amounts of water for cooling purposes. A large solar farm uses a minimum of 500 million gallons of water annually in order to function efficiently. Most solar plants are fighting with state regulators to get the water they need amid disapproval among conservation enthusiasts. An alternative “dry cooling” technique which uses ninety percent less water compared to “wet cooling” is available, but it...
When exotic animals escape
People love to gawk at exotic animals in zoos, aquariums and wildlife parks. Some self-important individuals even like to collect tigers, pythons and monkeys so they can show them off to friends or impress strangers. Remember the private animal collector in Ohio who released his collection of 56 exotic animals – including tigers, bears, lions and a baboon – and then killed himself? The police ended up killing nearly all the animals. That was an extreme example of what can go...
