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 [...]

Precision Nanobatteries by The Billions

Tiny batteries formed inside nanopores demonstrate that properly scaled nanostructures can use the full theoretical capacity of the charge storage material. These nanobatteries delivered their stored energy efficiently at high power (fast charge and discharge) and for extended cycling.

Precise structures can be constructed to assess the fundamentals of ion and electron transport in nanostructures for energy storage and to test the limits of three-dimensional nanobattery technologies.

Nanostructured batteries, when properly designed and built, offer promise for delivering their energy at much higher power and longer [...]

Simon Derricut: Free Energy Philosophy

Down at the philosophical base, it’s not actually Free Energy that we want. We want to get work done for free instead. Work can only be done when mass/energy moves from one configuration to another. After the work is done we have just the same amount of mass/energy as we started with, just in a different configuration. If we run a cyclical process, then at the same point in the cycle the mass/energy will be in a certain configuration and thus we need a way to persuade the energy in our system to return to an imbalance so that we can again do work with it. When we look at a Free Energy device, therefore, we need to look at how that imbalance is restored since this does not naturally [...]
