Green Options

The Dutch organization SNV has agreed to plant approximately 10,000 acres of land near the coastal Peruvian city of Piura for a biodiesel operation that will provide new jobs for Peruvians and help reduce poverty through sustainable development.

According to one of Peru’s major news sources, El Comercio, “The coordinator of SNV, Jhony Heredia Paivo, indicates that 5000 hectares have been identified in the coast and highlands of Piura where piñón blanco can grow, an almost wild plant that actually can be contained on small farms, that produces olive seeds that can serve as raw materials for biodiesel plants.”

A new proposal to improve a 75-year-old dike, the Afsluitdijk, in The Netherlands could make it the world’s leading site for generating saltwater power— a clean, renewable energy source which is 30-40% more efficient than burning coal.

The breakthrough process, which is called reverse electrodialysis, captures the energy created when freshwater becomes saltier by mixing with seawater. Although scientists in the 1950s discovered that electricity could be generated this way, no one knew just how efficient the process could be until a recent study proved that a remarkable 80% of the energy could be recovered.

Dutch-based EV start up Detroit Electric has announced that, by the end of next year, it plans to produce a range of affordable electric cars that are much more powerful than existing models and have zero emissions.

The company is in talks with Proton, the national Malaysian car-maker to produce the cars at their facilities in South East Asia. It is also in negotiations with two other, as yet unnamed, auto manufacturers from Germany and the U.S.

Speaking at a prototype viewing at the Proton test circuit in Malaysia, Detroit Electric’s Chief Executive, Albert Lam said, “We believe in affordable electric vehicles for the public. That is our dream … to find innovative ways to counter global warming.”

The cars, a sportscar, a sedan and a subcompact car, will feature a li-ion battery with a range of 200 miles on a single 7-8 hour charge and a total life span of 125,000 miles. They will also contain electric motor technology produced in-house. According to Chief Scientist Frits van Breemen-Schneider, the motor is 4 to 12 times lighter than exisiting designs, giving it a superior power-to-weight ratio. This means that it can produce 5kw of power per kilogram, whereas the best electric car in existence can only currently produce 0.25 kw per kilogram.

Now here’s an innovation that might make me consider moving back to New York City: air-purifying concrete. The small Dutch town of Hengelo is testing out the concrete paving stones, which contain a titanium-dioxide based additive that binds to nitrogen particles emitted by car exhaust and turns them into harmless nitrates.
