The News: Humdinger has launched small scale wind energy charger that is purportedly 10 times more effective at gathering energy than other systems of the same size. The piezoelectric turbine-based system uses aeroelastic flutter and vibration of a membrane - rather than a spinning turbine.The Good: It can be used in applications such as HVAC systems, using the airflow to power the device and therefore skipping the need for more expensive batteries. And because the system doesn't mess with spinning turbines that can break more easily, it expects a long lifespan - as much as 20 years.
The Bad: The company is still looking for funds to commercialize the discovery
