China Overtakes US in Scientific Articles, Robots, Supercomputers

Nothing illustrates China’s meteoric rise as some well chosen numbers.

By the end of the 1990s, China had come to dominate the mainstays of geopolitical power in the 20th century – coal and steel production. As a consequence, it leapt to the top of the Compositive Index of National Capability, which uses military expenditure, military personnel, energy consumption, iron and steel production, urban population, and total population as a proxy of national power. Still, one could legitimately argue that all of these factors are hardly relevant today. While Germany’s fourfold preponderance in steel production over Russia may have been a critical number in 1914, China’s eightfold advantage in steel production over the US by 2014 is all but meaningless in any relevant comparison of national power. The world has moved on.

Energy disruption: Solar plus storage to be cheaper than grid in 2017

Posted by in category: energy

Combination of solar plus storage to be cheaper than grid based power in Australia within the next year, meaning most of the energy use from households will be “hidden” from the networks. Time to think differently about the grid, and help consumers “share” energy.

New Molecular Mechanical Computer Design is 100 Billion Times More Energy Efficient

Posted by in categories: energy, supercomputing

This new computer system is 100 billion times more energy efficient than the most energy efficient conventional green supercomputer. Using only links and rotary joints, this “molecular mechanical computer” removes the need for parts that create friction and generate heat.

The trend for computing, and for technology in general, really consists of just one word: Smaller. Previously, technology that could fit on your desk was the rage. Then it became tech that fit in your bag. Then the palm of your hand. Now, scientists are playing with even smaller technology, down to the molecular size.

Scientists have developed a computer system that can, theoretically, be 100 billion times more energy efficient than the most energy efficient conventional green supercomputer. Using only links and rotary joints, this “molecular mechanical computer” removes the need for gears, clutches, switches, springs, and other parts that create friction and generate heat.

Engineers give new meaning to the phrase ‘cool clothes’

Posted by in categories: climatology, energy, engineering, habitats, sustainability

Cannot wait for this material so that I can finally enjoy my run in the park near my US home in August.


WASHINGTON — Engineers have created clothing for a warming world — a fabric that allows your body heat to escape far better than other materials do.

It hasn’t been worn or tested by humans, so outside experts caution this is far from a sure thing, but a team at Stanford University engineered a fabric using nano technology that not only allows moisture to leave the body better, but helps infrared radiation escape better. As a result, they say in Thursday’s journal Science, the body should feel around 4.8 degrees (2.7 degrees Celsius) cooler than cotton and 3.8 degrees (2.1 degrees Celsius) chillier than commercially available synthetics.

‘Star in a jar’ could lead to limitless fusion energy

Physicists at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) are building a “star in a jar” — a miniature version of the how our Sun creates energy through fusion. It could provide humankind with near limitless energy, ending dependence on fossil fuels for generating electricity — without contributing greenhouse gases that warm the Earth, and with no long-term radioactive waste.

But that requires a “jar” that can contain superhot plasma — and is low-cost enough to be built around the world. A model for such a “jar,” or fusion device, already exists in experimental form: the tokamak, or fusion reactor. Invented in the 1950s by Soviet physicists, it’s a device that uses a powerful magnetic field to confine plasma (superhot charged gas) in the shape of a torus.

Scientists Are Creating Micro Fuel Cells for Our Shrinking Technology

Researchers developed a method of transferring an energy source to virtually any shape using direct laser writing…

As electronics shrink in size, their energy sources have to fit into tighter, and sometimes more oddly-shaped, spaces. Researchers at the University of Missouri had this challenge in mind when they developed a method of transferring an energy source to virtually any shape using direct laser writing (DLW).

China using Technology over Nature: Weather Modification Office

Posted by in categories: climatology, economics, energy, finance, food

China has always been a frontrunner, especially in technological advancements. The country has engaged itself in increasingly audacious and ambitious projects. It is, therefore, no astonishment in calling China, ‘the rising power’.China has established Weather Modification Offices, that enables in manipulating weather using technology. The offices are a network of dedicated units that help in changing the weather throughout China. 55 billion tons of rain is created by China every year, making the country the largest cloud seeder on earth.

China has found the urge to manipulate weather mainly because of the extreme climate it experiences. The region has heavy downpour in rainy season while it suffers from drought in summers. Dust and sand storms are common in springtime. Moreover, given the fact that China has the largest population, it cannot afford to rely on climate. Most importantly, for agriculture. China found the only hope in technology in the manipulating weather for accruing benefits.

Weather modification offices require huge financial resources, human capital and weaponry. It is no wonder that China has spent millions of money on weather modification process. It has spent $150 million on single regional artificial rain program. China has escaped $10.4 billion dollars economic losses by employing weather modification system from 2002 to 2012. Over 35000 people have been employed to carry out this project. About 12000 rocket launchers are being used to fire pellets containing silver iodide into the clouds.
