Time is critical when rescuers are alerted to a swimmer in trouble, a surfer who's taken a dive or a yacht guest who has fallen overboard. The Dolphin 1 is a motorized, remote-controlled lifebuoy that is thrown in the water and then propels itself out to the person in distress.
Here’s a nifty lifesaving idea from Noras Performance out of Portugal. U-Safe is a lifesaving buoy that can drive itself around in the water by remote control, meaning it can reach a victim quickly, and transport them to safety if need be.
The LIFESAVER Jerrycan carries and purifies close to 5 gallons of water.
