The nation’s first commercial hydrokinetic turbine, which harnesses the power from moving water without the construction of a dam, has splashed into the waters of the Mississippi River near Hastings, Minnesota.

The 35-kilowatt turbine is positioned downstream from an existing hydroelectric-plant dam and — together with another turbine to be installed soon — will increase the capacity of the plant by more than 5 percent. The numbers aren’t big, but the rig’s installation could be the start of an important trend in green energy.

And that could mean more of these “wind turbines for the water” will be generating clean energy soon. (more…)

Who says water and electricity don’t mix? The world’s first solar-electric-diesel hybrid yacht will have you impressing the greenies at the Yacht Club and sailing the seas in style.

The Island Pilot DSe Hybrid catches rays with a 6.8 kW solar array that’ll get you to Margaritaville and back at 6 knots with zero emissions. But if the sun ain’t shining in Cocomo, you can crank up the Steyer Motors parallel hybrid system that mates a 75-horsepower diesel engine and a pair of 36-horsepower electric motors powered by a 20-kilowatt-hour battery pack.

The 40-footer was a hit at the recent Fort Lauderdale International Boat Show, where it was one of several green vessels and gadgets that ranged from the Epower Marine Calypso Classic electric fishing boat to the 100 percent recyclable propellers made by Piranha Propeller.

But it was the $600,000 DSe that really wowed the crowd.

The DSe can run for as long as two hours on battery power. Kick on the diesels and she’ll cruise at 13 knots while charging the battery pack through a pair of 25-kW generators. Run the diesel engine and electric motor in tandem and she’ll hit 15 knots. (more…)

In this season of specters and spooks, what could be scarier than a steel-winged robotic spy plane shaped like a bat? The aptly named COM-BATis a six-inch surveillance device that is powered by solar, wind, and vibrations. The concept was conceived by the US military as a means to gather real-time data for soldiers, and the Army has awarded the University of Michigan College of Engineering a five year $10-million dollar grant to develop it.

A San Diego start-up says it is using algae to make oil that can be refined into gasoline and other fuels that are both renewable and carbon-neutral, and it plans to produce 10,000 barrels a day within five years.

That’s a fraction of the 20 million or so barrels of petroleum the United States consumes each day, but Sapphire Energy says “green crude” production could ramp up to a level sufficient to ease our dependence on foreign oil, if not end it altogether.

Company CEO Jason Pyle says the algal oil is chemically identical to light sweet crude and compatible with America’s $1.5 trillion petroleum infrastructure, making it a direct replacement for oil. Although the algal fuels refined from it emit as much carbon dioxide as conventional fuels, the company says the emissions are offset by the photosynthetic process that uses sunlight, water and C02 to create algal crude.

“At the very worst, it’s carbon neutral,” Pyle says, calling the fuels a “benchmark for an entire new industry” and “a paradigm change.”

Giant whirlpools, 100-knot winds, some of Europe’s mightiest tides: The icy waters off Scotland’s northern tip are no place for pleasure craft. But they’re ideal for power-generation systems that harness the restless fury of the sea — which is why the European Marine Energy Centre has set up shop in the Orkney Islands.

Think of it as the Bonneville Salt Flats of hydrokinetics: EMEC offers companies a place to try out their clean tech. The center’s remotely operated vehicles film underwater, and microphones will eventually monitor for noise pollution. First in was Dublin-based OpenHydro, which recently began trials on its second turbine (shown here raised for inspection).

Carbon-free hydrokinetic power could ultimately provide up to 20 percent of the UK’s electricity needs. But environmental concerns may still sink the effort: Critics warn of industrialized coastlines and harm to sea life.

The US faces similar challenges — without a testing facility. The Federal Energy Regulatory Commission has okayed a pilot marine-power project for Makah Bay, off the Washington coast, but environmental approval is still pending. By the time the inevitable court battles are resolved, the waves may be lapping at our doorsteps.
