Restube - a lightweight, compressed-air lifesaver deployed upon incident

By - February 28, 2012 3 Pictures
Most anyone that can swim can handle a float across the pool without significant risk of drowning, but being out on a large, open body of water like the ocean or a lake brings dangers to even the surest swimmer. While a personal flotation device (PFD) is a simple solution that will keep you afloat, it can be restricting and cumbersome to wear, making it uncomfortable for athletic activities like surfing or kiteboarding. The Restube gives you some of the life-saving power of a traditional flotation device without the unwanted bulk and discomfort. Read More

The Bobber keeps the GoPro afloat and easy to see

One of the great features of the GoPro HERO actioncam is the fact that it is waterproof down to 197 feet (60 meters). Unfortunately, should you lose hold of your non-floating camera in the water ... well, even if it survives its trip down to the bottom of the ocean/lake, you’ll likely never see it again. That’s why The Bobber exists. Read More

Life saving Nebulus floatation device

By - November 18, 2007 2 Pictures
November 19, 2007 Over 50 deaths per year in the US and Canada are attributed to drowning when snowmobiles and ATVs (All Terrain Vehicles) crash through thin ice. In an effort to significantly reduce the risk of such tragedies occurring, the University of Minnesota in partnership with JTW Associates have developed the Nebulus Emergency Flotation Device - a self-inflating shell that deploys quickly and allows a water or ice rescue to be performed by one person without waiting for back up.

Patent granted for walking on water invention

By - October 30, 2006 4 Pictures
October 31, 2006 History suggests humans have always been captivated with the possibility of walking on water with references to it in Christianity, Hinduism and Buddhism. In Egyptian mythology the god Horus walked on water, and in Greek mythology Orion, the son of the gods walked on water. Indeed, Leonardo da Vinci even conceived a set of shoes and stocks which would enable this highly improbable act. Now, thanks to an invention by Massachusetts inventor Yoav Rosen, it seems we may be in need of a new colloquialism for the impossible. Rosen’s Da Vinci-like pontoon shoes have just been granted a patent by the United States Patent and Trademark Office (USPTO) for an “Upright Human Floatation Apparatus And Propulsion Mechanism” and enable him to do just that (video here). Rosen’s company wishes to focus its business activities on its equally remarkable standing kayaks, and is seeking to license or sell its water-walking technology. We spoke with Rosen about his invention. See a video here. Read More

The Surf Shark helps humans swim like a fish

By - October 26, 2005 16 Pictures
October 27, 2005 NEW IMAGES UPLOADED The Surf Shark and the Electric Dolphin are electric aquatic vehicles with a difference – instead of holding onto them as with all other diving and swimming aids, the Shark and Dolphin attached to your feet and propel you from behind, just like a fish and nearly as fast. The Surf Shark is the pick of the pair for speed, having two motors, each delivering 82 pounds of thrust and capable of pushing a swimmer through the water at more than 5 knots (10km/h) – that’s roughly twice the speed of Grant Hackett at World Record 1500 metre pace. The Dolphin has just one motor but makes up for its lesser speed with twice the life, being capable of delivering about half that speed for over an hour before needing a battery swap. Read More

V8 Dolphin goes on and under the water

By - May 31, 2005 25 Pictures
Next time you see a dolphin playing off-shore, diving and breaching the water, take a careful look because it just might be a Bionic Dolphin, with a motor and a human inside. The Bionic Dolphin or VASH (Variable Attitude Submersible Hydrofoil) has been a plaything for eccentric Northern Californian techno-artists for the last three decades but a wave of publicity in the last twelve months has seen the developers commit to creating and selling a production version. Specs are not yet finalised, but how does a two seater, tandem-control techno-toy with 400hp Corvette LS2 engine sound? It's already looking like the wildest ride in the sea! Read More

Cornelis Drebbel built three submarine in the 1620s - they all worked

By - February 16, 2005 2 Pictures
The world's first practical submarine was built in 1620 by Dutch engineer Cornelis Jacobszoon Drebbel, under the patronage of James 1 of England. Drebbel built three submarines according to the sketchy information available from that time, each larger than the last and the third being capable of carrying 16 people, of which 12 were the oarsmen. The oarsmen rowed one oar each, with the oars protruding from the side of the boat through waterproofed leather seals. Air was supplied by snorkel-like tubes that were held above the water's surface by floatation devices, enabling the submarine to be underwater for long periods. Accounts suggest the boat could travel from Westminster to Greewich and back under water, completing the return journey in three hours at a depth around 15 feet below the surface. Read More
