The Blue Freedom brings hydropower to your backpack

The all-new Blue Freedom kit offers yet another alternative to solar panels, fuel cells, muscle-powered dynamos, wind turbines, AC-charged back-up batteries and other portable power solutions. "The world's smallest hydropower plant" transforms the power of running water into phone chatting, internet browsing, music listening, GPS navigating and other mobile device activities, and it does so from a package built to fit in a backpack.  Read More

A previous LucidPipe installation, with one of the turbines visible inside the pipe (Photo...

There's a lot of water constantly moving through the municipal pipelines of most major cities. While the water itself is already destined for various uses, why not harness its flow to produce hydroelectric power? Well, that's exactly what Lucid Energy's LucidPipe Power System does, and Portland, Oregon has just become the latest city to adopt it.  Read More

The Ice Harbor Dam in Washington state where Sensor Fish testing is done

It’s a tough row to hoe for young salmon in the Pacific Northwest as they make their perilous journey from upriver to the ocean. Besides hungry birds and sea lions, the regions many hydroelectric dams and their swirling turbines produce manmade currents and other obstacles that make it challenging for the fish to navigate. But now with the help of an artificial Senor Fish created by the Pacific Northwest National Laboratory (PNNL), existing larger dams and newer, smaller hydroelectric facilities can become more fish-friendly.  Read More

According to the designers, they have produced and flown a scale prototype of the blimp

Using a tethered airship floating high up amongst the clouds, the Air HES concept claims to yield both clean water and electricity by harvesting and condensing water vapor which it uses to spin up an electric turbine generator to create power. According to the creators, they have built a prototype to test their theory and have also conducted feasibility studies into upping the scale of their device to produce economically viable levels of water and power.  Read More

TipTapTop attaches to a faucet to make hand-washing more effective, more eco-friendly and ...

Dyson Award season is rolling around again, showcasing the work of young engineers and designers from around the globe. Here's one French device that's been entered with the goal of teaching kids how to wash their hands in a hygienic manner, without wasting water, while trying to make it as fun as possible. The 3D-printed TipTapTop might end up being an incredibly annoying thing to have in your bathroom, but the way it goes about its job is quite clever.  Read More

The three young inventors of the Pluvia system, which uses rainwater runoff to generate el...

When we complain about the rain, other people will often say "Yeah, but it's good for the plants." Well, thanks to a microturbine-based system created by three students from the Technological University of Mexico, it's now also being used to generate electricity for use in low-income homes.  Read More

The HydroBee generates electricity using the current of a stream or river

There are already plenty of gadgets that allow people to charge their mobile devices while off the grid. Most of those products utilize solar power, while a few have gone the thermoelectric route. The HydroBee, however, generates electricity using the power of flowing water – think of it as a portable hydroelectric station.  Read More

The floating prison concept is not just self-sufficient, but actually creates electricity ...

However efficient a prison may be, it still typically expends significant energy resources. But what if a prison could actually create power, rather than just consume it? That's the thinking behind lecturer in architecture Dr. Margot Krasojevic's futuristic offshore floating Hydroelectric Waterfall Prison concept, which isn't just self-sustaining, but produces excess energy for homes on the mainland too.  Read More

By exploiting pressure at the seabed, researchers hope to create stores of energy at the o...

"Imagine opening a hatch in a submarine under water. The water will flow into the submarine with enormous force. It is precisely this energy potential we want to utilize." This is how German engineer Rainer Schramm describes his idea for storing energy under the sea. By using surplus energy to pump water out of a tank at the seabed, the water is simply let back in again when there's an energy shortfall, driving turbines as it rushes in. The deeper the tank, the more power is generated.  Read More

The Cappa compact hydropower generator can deliver 250 W of electricity

Despite being the most widely used form of renewable energy worldwide, hydroelectricity is generally reserved for large-scale commercial installations built around massive dams. Japanese company Ibasei has shrunk things down and removed the need to build a dam with its Cappa compact hydropower generator – a system that's designed to be installed along a river or waterway.  Read More
