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.
Dow Chemical and several other companies have launched a program in Omaha, Neb. to divert about 36 tons of plastics from landfills in its first phase, and convert it into energy used for cement production.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
