https://www.youtube.com/watch?v=CDlvjkfpX_o The Linthal hydropower plant is accessible only by cable car, after a scenic jaunt through winding mountain roads. The mouth of the tunnel that descends to the subterranean hydroplant is located at 1,800 meters (5,900 feet) above sea level. At the command of the plant’s operator, Swiss utility Axpo, massive steel valves are opened, allowing water to flow from Lake Mutt to Lake Limmern, which are separated by a 2,000-foot cliff. The pump is twice the height of the Eiffel Tower. Nearly 23 billion gallons of water stop behind a dam in the valley, creating a temporary reservoir that feeds the plant’s four variable speed hydro generators. Related: World’s longest, deepest rail tunnel opens after almost 20 years of construction When demand for power is low, the flow on the valve is simply reversed, pumping water from the lower reservoir back up to Lake Mutt, where it can be stored until it’s time to generate more electricity. In this way, General Electric touts the power plant as a kind of natural battery . “It’s the only grid-scale method of storing energy,” says Maryse François, the hydrotechnology leader at GE Renewable Energy, which developed the technology powering the site. The Linthal plant marks the first place GE has installed its variable-speed technology, which takes the common concept of pumped storage to a whole new level. Having this sort of control over a massive renewable energy power plant can make a world of difference to the local power grid. The valves controlling the water make it possible to change the plant’s net energy output, absorb spikes in demand, as well as help utilities stabilize the grid and reduce brown-outs. The system’s efficiency also makes it a big win, not only for clean energy but for the local economy as well. At its peak, the overall cycle efficiency can reach as high as 80 percent. When all four generators are in operation, the plant will churn out a whopping 1,450 megawatts of renewable electricity. That’s enough to power a million Swiss homes during peak consumption times, which accounts for nearly one-third of the country’s population. + GE Reports Images via General Electric

Comments Off on GE’s new dome-shaped wind turbine generates more electricity

Perhaps the most interesting thing about technology of any kind is its ability to be adapted and improved. For wind turbines, GE ’s New ecoROTR  offers such an advancement. The addition looks like something out of a superhero movie—specifically, a certain shield-wielding Avenger comes to mind—and what it does for the wind turbine is equally super. The dome-shaped attachment allows this turbine to capture wind energy that is lost by standard turbines.

GE Announces $10B Investment in Clean Energy R&D, Including Eco-Friendlier Fracking?

Wind turbine image / Shutterstock The US-based conglomerate General Electric recently announced that it will spend an additional $10 billion researching and developing clean energy technologies over the next six years. As a major player in the solar and wind markets, GE’s decision to throw more money behind these technologies is happy news for green power advocates. The only drawback is that GE has included hydraulic fracturing in its stable of clean energy research projects. The company stated that its “new investment will support research in alternative technologies to replace water in hydraulic fracturing, known as ‘ fracking ,’ and improve wind turbine and power plant efficiencies.” Read the rest of GE Announces $10B Investment in Clean Energy R&D, Including Eco-Friendlier Fracking?

Comments Off on California Farmers Won’t Get Water from the State This Year

California is experiencing one of its driest periods in recorded history , and now local farmers are being told not to expect any water from the state. Federal officials from the Bureau of Reclamation released a new report last Friday that shows California’s snowpack is currently sitting at 29 percent of the average for this time of year. As a result, state and federal officials are not expected to release water reserves for farmers.

Image via Shutterstock Early detection of cancer is often crucial to patient survival, but in many parts of the world people just can’t afford the cost of an expensive diagnosis. To combat the rise of cancer rates in developing countries, MIT engineers have developed a revolutionary paper-based urine test that could cheaply and effectively diagnosis whether a person has cancer in mere minutes. The test, which works similarly to a pregnancy test, uses synthetic biomarker technology to eliminate the need for expensive, specialized equipment.
