Electric Fish Paves Way For Underwater Robots?

black ghost knife fish could pave way for underwater robots

You had us at underwater robots!

According to a new study by scientists, the way in which an electric fish "squirts jets of water from its body" could pave the way for underwater robots.

Here's what researcher Malcolm MacIver had to say about their research subject, the black ghost knifefish:

"They can sense in all directions. This raised the question of whether they had a propulsion system that could generate forces in all the directions they would need to get the most out of such a sensory system."

So far, it seems like studies/tests involving the knifefish have been going well.

More from MacIver on underwater robots:

"One thing lacking in the field is an underwater robot with high maneuverability. After the BP oil spill disaster, a remotely operated vehicle banged into the oil well head, and the reason for that is that current technology is about as easy to steer as a submerged bathtub. What are really needed for these operations are underwater vehicles that can move with the agility of underwater animals.

Most underwater robots use light and cameras for sensing, which can require kilowatts of energy to see something. The sensory system of our robot is very, very low power, just like the fish in the Amazon. Coupled with an extremely energy-efficient propulsion system, we hope to have a robot that requires very low energy and thus can go long distances for long [spans of] time."

We wish these scientists the best of luck with their research.

Hooray for the black ghost knifefish!

Yotam Solomon's Oily Spring Collection

Eco-friendly designer Yotam Solomon is doing his best to raise awareness about the environment, especially after what happened in the Gulf of Mexico this year.

His upcoming spring collection dubbed "Oil Spill" was inspired by the devastating BP oil spill, which he believes is "a major event in our decade and even century".

The 2011 collection includes a variety of heels, dresses and chic separates. Solomon has also pledged to donate a portion of sales to the Defenders of Wildlife and Natural Resources Defense Council for all the work they did in the Gulf.


What do U think of Yotam's collection???
