This Is A Sailboat And Those Are Sails

Posted by in categories: energy, physics

We are undeniably using up what little remains of Earth’s petroleum, and because of that, it’s getting expensive. To reduce fuel costs, shipping companies are turning back to sailboats. Yes, seriously. Sailboats. But they don’t look like any sails you’ve seen before.

You know sails – most of the time big rectangle things, sometimes big triangle things, almost always (but not always-always) made out of cloth. But while those things in the top gif don’t look like your normal sails, that’s what they are. They just don’t work like any sail you’ve ever seen before.

Most sails you’ve seen rely on the wind directly acting against them to provide propulsion. But these new types of sails, known as “rotor sails” rely on a physics principle called the Magnus Effect. Here, I’ll let the people with delightfully thick Finnish accents from Norsepower, the company that makes them, explain it:

This bright blue dye is found in fabric. Could it also power batteries?

Posted by in categories: energy, habitats

A sapphire-colored dye called methylene blue is a common ingredient in wastewater from textile mills.

But University at Buffalo scientists think it may be possible to give this industrial pollutant a second life. In a new study, they show that the dye, when dissolved in water, is good at storing and releasing energy on cue.

Tidal energy turbine company is showing good results

Posted by in categories: energy, engineering

Scotrenewables Tidal Power, a Scottish engineering company, is focused on an energy source they call “tidal energy generation.” A video promoting their solution: They have plenty to show for their efforts, namely, the world’s most powerful operational tidal turbine, the SR2000 2MW.

A reduction in manufacturing and installation costs plus simple, quick and low cost maintenance strategies will be key to success.

Researchers manipulate individual graphene dislocations on the atomic scale

Posted by in categories: energy, transportation

Materials can deform plastically along atomic-scale line defects called dislocations. Many technical applications such as forging are based on this fundamental process, but the power of dislocations is also exploited in the crumple zones of cars, for instance, where dislocations protect lives by transforming energy into plastic deformation. FAU researchers have now found a way of manipulating individual dislocations directly on the atomic scale.

Using advanced in situ , the researchers in Prof. Erdmann Spiecker’s group have opened up new ways to explore the fundamentals of plasticity. They have published their findings in Science Advances.

Ethiopia opens plant to turn waste into energy

Posted by in categories: energy, government, sustainability

Ethiopia on Sunday inaugurated a power plant which converts waste into energy, next to a filthy open-air dump in Addis Ababa where a landslide last year killed more than 110 people.

Named Reppie, the facility is the first of its kind in Africa, according to the government and the British company Cambridge Industries behind the project, and will turn 1,400 tons of per day into .

Ethiopian President Mulatu Teshome said at the ceremony that the country “has been investing extensively in , geothermal, wind energy and now biomass to boost the manufacturing sector with a supply of clean, renewable energy.”
