Dousing Flames with Low-Frequency Sound Waves

A new type of extinguisher that uses sound waves to put out fires has been built by two engineering students in the US. Both chemical- and water-free, the invention offers a relatively non-destructive method of fire control, which could find applications in fighting small fires in the home, and the researchers now hold a preliminary patent application for their device.

While the concept of using sound waves to extinguish flames is not new, previous attempts to realize the principle – including efforts by teams at West Georgia University and the US Defense Advanced Research Projects Agency (DARPA) – had not been successful.

Undeterred by this, as well as initial [...]

New Power Generation Coming Primarily from Wind.

Wind power will make up almost half of all new utility-scale electric generation in 2015, the U.S. Energy Information Administration said, while coal power plants are retiring because of federal emissions rules.

Electric companies plan to add more than 20 gigawatts of capacity to the grid this year, with wind making up 9.8 gigawatts of the load, the EIA said Tuesday. The next big additions are natural gas (6.3 gigawatts) and solar (2.2 gigawatts).

Meanwhile, almost 16 megawatts of capacity will retire this year, with most – 12.9 gigawatts – being coal-fired plants…

Israel’s Solar-Powered ‘Trees’: For Smartphones And Community

Instead of taking your laptop to a coffee shop in Northern Israel, you might want to go sit under a tree instead.

A brown metal sculpture of a tree trunk with branches rising to the sun holding seven solar panels aloft was unveiled in a park this month near Mount Carmel. The eTree provides shade and power as well as wi-fi and chilled drinking water for dogs and people.

Solar energy expert Michael Lasry dreamed up the design and hired an artist to bring a new way of enjoying solar power to the community.

ETree provides a relaxing shaded resting area for passers by and, with the energy produced from the solar panels, offers services such as: mobile phone charging [...]
