Tokelau leads the world!

I’ve been looking for some positive stories for Christmas. What can be more positive than Tokelau going almost completely to renewables?

I guess it helps if you’ve got only 1,500 people and three cars.

Harnessing desert sun power

We’ve posted before on Desertec, the plan to generate solar power in North Africa and pipe it to Europe, to supply up to 15% of its energy by 2050. They expect to see the first solar electricity flowing from Morocco to Spain as early as 2014.

This report tells us that Morrocco itself “wants to produce 42% of its electricity from renewable sources – solar, wind and hydro-electric – by 2020.” That’s got to be good.

There are critics, however:

Valentin Hollain of Eurosolar, a German non-profit organisation that promotes renewable energy, queries the entire concept of Desertec.

He argues that big corporations are using large-scale projects like Desertec and Medgrid to retain their position into the next generation, and that a mix of renewable power supplied locally can meet demand while keeping prices down for consumers.

Herr Doktor Hüttlin’s magical Kugelmotor

From Gizmag via John D comes an invention from the Black Forest area of a spherical engine that can drive directly, generate electricity or store energy from braking in the motor itself. There seems to be considerable potential for it as a range extender in plug-in electrics.

“Pre-production prototypes of 1.18 liter capacity have been in testing for some months and power output at present is 74kW (100hp) at 3000rpm with torque up to 290Nm (213ft-lb). Dr Hüttlin expects efficiency to increase by another 40% with reduced bearing friction and optimization of the combustion. The engine weighs 62 kg and consists of only 62 parts, while a conventional engine has at least 240.” Continue reading Climate clippings 46
