UMD engineers develop first biocompatible ion current battery. (Image credit UMD)   UMD engineers have designed a new type of ion current battery that’s completely biocompatible. The new battery produces the same ion-based energy used by humans and other living organisms, and those ions (in the form of sodium, potassium and other electrolytes) are the electrical signals that do everything from powering the brain to flexing muscles. To get a better sense of what’s going on here ...
A team of researchers at Berkeley Labs have discovered a seaweed derivative can stabilize lithium-sulfur batteries. The seaweed derivative acts a binding agent for the sulfur (Photo via Berkley Lab)   Our search for the most reliable battery never seems to end. While lithium-sulfur batteries are best for powering gadgets, vehicles, and application grids, their biggest drawback is its lifespan ─ Sulfur dissolves making the batteries unreliable. But a team from the Department of Energy’ ...

PLC simulator

Posted by andrewblog Aug 19, 2017
Ladder diagram is the most used PLC programming language. Main ladder logic elements work like electromechanical circuits, in other words they are virtual relays. A PLC exchanges information with the external environment through input and output terminals. Swithces and sensor are connected to input terminals. Output terminals are supposed to control contactors, actuators, lamps, etc. This video shows how to use a PLC simulation software. The new version is available here.   ...
Hydrogen is a very attractive prospect for alternative energy sources, and prior obstacles to the utilization of hydrogen power are being overcome through the introduction of a new aluminum alloy material and its unique reaction to water. Recent developments give greater credibility to the notion that hydrogen power could replace battery power appliances and products, ranging from laptops to cars and buses.

(Image credit Facebook Research)   Professor Stephen Hawking and Elon Musk are staunch opponents when it comes to the advancement of AI, feeling that it could lead to the downfall of the human race and maybe they’re right. Just read the back and forth communication from a pair of Facebook AI agents:     -Bob: “I can can I I everything else.”     -Alice: “Balls have zero to me to me to me to me to me to me to me to me to.”   C ...
