Ocean Monitoring by Jellyfish
US Scientists Enable Jellyfish to Swim 3-times Faster
New Invention with Big Potential to Monitor Health of Oceans
Scientists at Stanford University and Caltech have created a pacemaker-like device that enables natural jellyfish to swim three times their normal speed. The microelectronic, pulsing, tiny, prosthetic device generates electric jolts that make the fish triple their speed while using just twice as much energy. The scientists and engineers involved in the project says the device causes no additional stress to the sea creatures. They say the potential for this system is as vast as the ocean itself.
Network of Live Ocean Monitors
The scientific team says the combination of speed and energy efficiency from this device opens the possibility of using jellyfish to gather data from across the world's oceans. They envision equipping the jellyfish with sensors to track ocean temperatures, salinity and oxygen levels. They say this could lead to a truly global network of ocean monitors composed of robotic jellyfish that would cost just a few dollars to instrument. The fish would generate energy from their normal ocean food. Obviously this system needs a tremendous amount of research and development. But, it's a fascinating look at instrumented jellyfish monitoring the health of world oceans.
Robot, Cut My Lawn Source: Husqvarna Mowers Robo Mowers Powered by Batteries - No Gas It's at the top of my robotic wish list. A robot lawn mower. No astronomical bills and upselling from lawn service companies. Just a nicely cut lawn and no hassles. Innovation seems to be knocking at the front door with news on robotic mowers. Green Robots at the Cutting Edge There's a slew of new robot mowers. Models include Worx Landroid for smaller lawns, Honda that cuts and feeds lawns, Robomow for all-purpose mowing and Husqvarna that's loaded with cell & GPS tech. These mowers aren't cheap. Prices range from $1000 to $3500. They're powered by rechargeable batteries so they're quiet. You pay more for online enhancements. And, if your lawn is loaded with trees and hills, your robot mower is going to be a lot more expensive. Grass Vacuums Robot mowers look a lot like big robot vacuums such as iRobot's Roomba. They roam and groom your lawn. Their

New Invention: Tablet Toothpaste "Change Toothpaste" Source: Change Toothpaste Potentially Cuts 900 Million Plastic Toothpaste Tube Throwaways Per Year Tubes of toothpaste aren't something you think about but their impact on the global environment is hugely negative. 900 million toothpaste tubes are discarded into oceans and landfills globally every year. Importantly, it takes 500 years for them to breakdown, which means virtually every toothpaste tube created is still discarded someplace in the world. And, the tubes, which contain multiple layers of plastic, polymers and resins, can't be recycled. A company headquartered in Edmonton, Alberta Canada just came up with a solution in the form of tablet toothpaste. "Paste with No Waste" Entrepreneurs Mike Medicoff and Damien Vince are the inventors and founders of CHANGE Toothpaste. Their tablet toothpaste is an all natural vegan substance that works just like toothpaste but has no harsh chemic
