Liquid Robotics' new Wave Glider robot, the SV3 (right, in red) is bigger than its predecessor, SV2 (left, in yellow), shown during sea trials in Hawaii. The SV3 uses stored solar energy for part of its propulsion system, combined with the Wave Glider's unique, wave-powered energy harvesting system. (Source: Liquid Robotics)
Ann, this is a remarkable integration of a number of technologies -- solar, battery, energy storage, conversion of ocean movement. If you gather a number of technologies together no sngle technology has to be perfect. This is a good example.
It's nice to see the evolution of this useful and innovative robot as it uses alternative energy sources, Ann. I wrote about this technology awhile back and thought it always had a solar component, though? Is this just an extension of that? Or was I misled or mistaken?
Elizabeth, the Wave Glider you and I have both written about before did have solar, but it was not used for propulsion--instead, it powered the instruments in the payload, as the article states, and as is still the case. Now, some of that solar energy is also stored and used for propulsion.
Rob, thanks for that observation--I agree about the integration of technologies. That, plus using solar for propulsion, is why I wanted to share this with our readers. It's also why the robot won the Edison Award even before this latest innovation.
I would imagine the integration of emerging technology will become more common. There are so many new sustainable technologies that are getting proved, it's only natural that end products will begin to show up with a convergence of new technologies.
Ahan Ann , Thats really very great uptill now i have only heard about unmanned ground vehicle but this is the very first time i came to know about unmanned marine vehicle with soo many add on features included into it. These sort of marine robots are really very usefull as they help us to gather all the marine information in any type of climate cost effectively . With these sort of unmanned marine vehicles we can keep ourselves aware from earth quakes, tsunamis, and ocean storms etc without engaging any human life in it .
Agreed, Rob. The interesting twist here is that the two sources -- solar and waves -- would seem to be complementary. Typically, the sea is at it's calmest under a clear sky and the waves are highest under overcast skies. If that's the case, one source provides power while the other is idle.
HP revealed more of its 3D printing plans in a recent webinar. Senior vice president of inkjet and graphics solution business Stephen Nigro spoke about how the technology works and expanded on HP's vision of open collaboration to commercialize its Multi Jet Fusion 3D printing technology for end-production, and open collaboration on new materials. He also said HP will create software to help users decide when to use Multi Jet Fusion versus conventional subtractive manufacturing.
A lightweight electric urban concept car designed by several European companies weighs only 992 lb without its battery. It would have weighed 26.7 lb more if its windows were made of glass instead of the specially coated LEXAN polycarbonate resin from SABIC Innovative Plastics.
Skylar Tibbits' team in MIT's Self-Assembly Lab is now 4D printing self-assembling shapes made of programmable carbon composites and custom wood grain. The composites are being used in a sport car airfoil, and the wood grain is beautiful.
The NanoSteel Company has produced high-hardness ferrous metal matrix composite (MMC) parts using a new nanosteel powder in a one-step 3D-printing process. Parts are 99.9% dense, crack-free, and with wear resistance comparable to M2 tool steels.
