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 [...]
This summer, a small armada of vessels from all over the globe will converge in the Pacific Ocean. Their arrival is expected to herald what arguably can be called one of the more creative environmental cleanup projects. As many as fifty boats consisting of everything from research vessels to private cruisers, sailboats and commercial fishing vessels will track the Pacific’s Great Garbage Patch as it makes its rocky journey through currents between Hawaii and the California coastline.
The mega exploration, as the team at the nonprofit organization, The Ocean Cleanup, calls it, will help the organization close in on their efforts to clean up the [...]
