A climate scientist and Google Science Communication Fellow who works at San Jose State University (SJSU), Eugene Cordero is passionate about what he calls “science that matters to society.” Cordero’s aim is to reduce annual carbon emissions by 1 million tons using the power of a climate-action superhero called the Green Ninja. The Green Ninja comes to life in a series of videos and social media tools designed to educate and inspire action to reduce our carbon footprint. Cordero is also co-author of the book Cool Cuisine: Taking the Bite out of Global Warming.

The Passive House in the Woods in Hudson Wisconsin officially clocked a net-energy positive meter reading in 2011.
What does that mean?
In short, itÂ made more energy than it consumed. While we predicted this with our energy models, we found and learned through monitoring that some equipment and appliances use more energy than assumed. On the flip side, user behavior plays a major role as well and can effectively lower energy consumption over the predicted model. (Source)
Itâ€™s a utopian fantasy- discover a ghost town and rebuild it in line with your ideals-, but in Spain where there are nearly 3000 abandoned villages (most dating back to the Middle Ages), some big dreamers have spent the past 3 decades doing just that.
There are now a few dozen â€œecoaldeasâ€ – ecovillages – in Spain, most build from the ashes of former Medieval towns. One of the first towns to be rediscovered was a tiny hamlet in the mountains of northern Navarra.
It was rediscovered in 1980 by a group of people living nearby who had lost their goats and â€œwhen they found their goats, they found Lakabeâ€, explains Mauge CaÃ±ada, one of the early pioneers in the repopulation of the town.
The new inhabitants were all urbanites with no knowledge of country life so no one expected them to stay long. At first, the homes werenâ€™t habitable so they lived 14 in a large room. Slowly they began to rebuild the homes and the gardens.
When they first began to rebuild, there was no road up to the town so horses were used to carry construction materials up the mountain. There was no electricity either so they lived with candles and oil lamps.
After a few years, they erected a windmill by hand, carrying the iron structure up the hill themselves. â€œEven though it seems tough and in some ways it was, but you realize you’re not as limited as you think,â€ says Mauge. â€œThere are a lot of things people think they can’t do without a lot of money and there’s never been money here.â€
In the early years, they generated income by selling some of their harvest and working odd jobs like using their newfound construction experience to rebuild roofs outside town. Later they rebuilt the village bakery and sold bread to the outside world.
Their organic sourdough breads now sell so well that today they can get by without looking for work outside town, but it helps that they keep their costs at a minimum as a way of life. â€œThere’s an austerity that’s part of the desire of people who come here,â€ explains Mauge. â€œThere’s not a desire for consumption to consume. We try to live with what there is.â€
Today, the town generates all its own energy with the windmill, solar panels and a water turbine. It also has a wait list of people whoâ€™d like to move in, but Mauge says the answer is not for people to join what they have created, but to try to emulate them somewhere else.
â€œIf you set your mind to it and there’s a group of people who want to do it, physically they can do it, economically they can do it. What right now is more difficult is being willing to suffer hardship or difficulties orâ€¦ these days people have a lot of trouble living in situations of shortage or what is seen as shortage but it isn’t.â€ (Source)
A schoolboy from Nepal has come up with a recession-busting new solar panel which replaces the silicon component with human hair. Milan Karki, an 18-year-old student from the region of Khotang, devised the idea after discovering that hair pigment Melanin acts as an energy converter.
Each panel, which is around 15 inches square, produces 9 Volts (18 Watts) of energy, and costs $38 to make. This, it has to be said, is mainly due to the price of the raw materials: half a kilo of human hair costs around 25Â¢ in Nepal. Karki is hoping to commercialize his invention, which can charge a cellphone or power batteries to provide an evening’s worth of light, and eventually mass produce it.
“First I wanted to provide electricity for my home, then my village,” says Karki, who was inspired by British physicist Stephen Hawking. “Now I am thinking for the whole world. We have begun the long walk to save the planet.” (Source)
Solar-sintering aims to raise questions about the future of manufacturing and triggers dreams of the full utilisation of the production potential of the worldâ€™s most efficient energy resource – the sun. Whilst not providing definitive answers, this experiment aims to provide a point of departure for fresh thinking. :Read on:
