High-power biological wheels and motors imaged for first time
Posted by Karen Hurst in categories: energy, nanotechnology
Behold – the only known example of a biological wheel. Loved by creationists, who falsely think they are examples of “intelligent design”, the bacterial flagellum is a long tail that is spun like a propeller by nano-sized protein motors.
Now these wheels and their gearing have been imaged in high resolution and three dimensions for the first time. Morgan Beeby and his colleagues at Imperial College London used an electron microscope to resolve the mechanisms that provide different amounts of torque to the motors.
The motors are diverse, coming in a wide variety of shapes, sizes and power outputs. Indeed, the diversity of the motors and the fact that they have evolved many times in different bacterial lineages, scuppers the creationist view that the machinery is “irreducibly complex”.

Samsung announces new 14nm, octa-core SoC: Exynos 7 Octa 7870
Posted by Shailesh Prasad in categories: energy, mobile phones
Samsung is bringing second-generation 14nm technology to its midrange smartphone devices this year, along with (we hope) a solid battery life boost. Hopefully manufacturers will use 14nm power savings to offer devices that prioritize battery life over shaving a few millimeters off the frame.

Tiny, artificial trees could form the next generation of windmills
Posted by Shailesh Prasad in categories: energy, materials, sustainability, transportation
Researchers in the US have proposed a new form of wind power: small, artificial, mechanical trees capable of producing energy from their vibrations. Working with the natural breeze, or small movements caused by other factors, the scientists hope that new forms of renewable energy can be developed in the future.
The idea is to create a device that can convert random forces – whether that’s from the footfall of pedestrians on a bridge, or a passing gust of wind – into electricity that can be used to power devices. And the researchers have found that tree-like structures made from electromechanical materials are perfect for the task.
“Buildings sway ever so slightly in the wind, bridges oscillate when we drive on them and car suspensions absorb bumps in the road,” said project leader Ryan Harne from Ohio State University. “In fact, there’s a massive amount of kinetic energy associated with those motions that is otherwise lost. We want to recover and recycle some of that energy.”

ARPA-E Funding Personal Climate Control Systems with Robots, Foot Coolers, and More
Posted by Karen Hurst in categories: energy, government, robotics/AI, sustainability
Government’s other big NextGen Program “Advanced Research Projects Agency-EnergyAdvanced Research Projects Agency-Energy” (ARPA) is funding a personal climate change solution with robots, foot coolers, etc. There is one fact; US Government does love their acronyms.
Why heat or cool a whole building when you could heat or cool individual people instead?

Russian officials again talk about a working lab prototype megawatt class nuclear propulsion system
Posted by Klaus Baldauf in categories: energy, space travel
A Russian Megawatt-class nuclear propulsion system for long-range manned spacecraft must be ready by 2017, Skolkovo Foundation’s Nuclear Cluster head Denis Kovalevich said on Wednesday.
“At present we are testing several types of fuel and later we will start drafting the design,” Kovalevich said. “The first parts [of the nuclear engine] should be built in 2013, and the engine is expected to be ready by 2017.”
The engine is being developed for interplanetary manned spacecraft to ensure that Russia maintains a competitive edge in the space race, including the exploration of the Moon and Mars.
