#hydrogeneration — Public Fediverse posts

Took a walk in a park yesterday. Poplars in autumn are gold. Plenty of leaves to keep the pups happy.
Otematata is still a reasonably quiet town, built by the Ministry of Works in the 60s. It was home to several thousand Hydro Dam builders. They built two dams here. ( Another further down was built earlier)
One being the largest Earthern Dam in the southern hemisphere, Benmore. The other is Aviemore.
As well as generation of electricity, the lakes formed are now enjoyed for recreation. Fishing and boating and camping holidays.
A beautiful area anytime of the year.

I'm fascinated with the concept of #Hydrogeneration -- using waves to generate electricity in a moving boat! Kinda like a flywheel generator on a bicycle!

#Sailors embrace green tech with electric motors and #solar power

Advances in eco-friendly options are persuading some yacht owners to ditch diesel

"When the wind dies, sailing boats typically rely on diesel engines, which are noisy and polluting. Now, just as electric motors are taking over the auto industry, electric motors are winning over sailors, too.

"Two years ago, the Metstrade exhibition design winner was #Oceanvolt, a Helsinki-based electric motor manufacturer. The company is one of the few in the world that sells a completely electric propulsion system — which combines solar panels on deck with batteries to generate electricity.

"The Oceanvolt propulsion system is also innovative in its use of hydrogeneration. When a sailboat is enjoying good wind and is moving without a motor, the Oceanvolt propellers can generate electricity as the water flows past them. Oceanvolt says its system can generate up to five kilowatts of power to charge equipment and batteries, depending on how fast the boat is going."
