Most small portable generators have the output fixed by design such that the output voltage is a function of speed, there is no voltage regulator. If the generator overspeeds the output voltage will climb proportionately. While it's far from common, it is not that uncommon for a standby generator that sits for long periods to have the governor stick due to rust, animal hair, or other debris that falls onto the throttle/governor. It happens to lawn mowers and snow blowers as well. Thank goodness for insurance.
That's a pretty scary story, especially for a generator that appears to be pretty new. Despite the helping hand generators can provide, there are some pretty frightening complications if they don't run properly. I'm somewhat surprised that the manufacturer didn't buck up for a full replacement as opposed to simply just fixing the defective model. It would seem that would be a more economical and PR-friendly route than subjecting themselves to a potential lawsuit.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
