Can optical technology solve the high performance computing energy conundrum?

Posted by in categories: energy, quantum physics, supercomputing

Another pre-Quantum Computing interim solution for super computing. So, we have this as well as Nvidia’s GPU. Wonder who else?


In summer 2015, US president Barack Obama signed an order intended to provide the country with an exascale supercomputer by 2025. The machine would be 30 times more powerful than today’s leading system: China’s Tianhe-2. Based on extrapolations of existing electronic technology, such a machine would draw close to 0.5GW – the entire output of a typical nuclear plant. It brings into question the sustainability of continuing down the same path for gains in computing.

One way to reduce the energy cost would be to move to optical interconnect. In his keynote at OFC in March 2016, Professor Yasuhiko Arakawa of University of Tokyo said high performance computing (HPC) will need optical chip to chip communication to provide the data bandwidth for future supercomputers. But digital processing itself presents a problem as designers try to deal with issues such as dark silicon – the need to disable large portions of a multibillion transistor processor at any one time to prevent it from overheating. Photonics may have an answer there as well.

FBI Warns of Cyber Threat to Electric Grid

Posted by in categories: cybercrime/malcode, energy, government

Three months after a Department of Homeland Security intelligence report downplayed the threat of a cyber attack against the U.S. electrical grid, DHS and the FBI began a nationwide program warning of the dangers faced by U.S. utilities from damaging cyber attacks like the recent hacking against Ukraine’s power grid.

The nationwide campaign by DHS and the FBI began March 31 and includes 12 briefings and online webinars for electrical power infrastructure companies and others involved in security, with sessions in eight U.S. cities, including a session next week in Washington.

The unclassified briefings are titled “Ukraine Cyber Attack: Implications for U.S. Stakeholders,” and are based on work with the Ukrainian government in the aftermath of the Dec. 23 cyber attack against the Ukrainian power infrastructure.

Meet Behrokh Khoshnevis, the Man Designing Robots to Build Colonies on Mars

Posted by in categories: energy, robotics/AI, space

When Khoshnevis imagines the future of colonies on Mars, he imagines very tall buildings, with a lot of protection from the elements.

“Gravity is one third of Earth’s, and therefore with less construction material we can build stronger structures out there, therefore we can build much taller,” he says. “The cost of energy for elevators and all that will be much less. Theoretically everything could be three times as high as here with the same consumption of energy,” he says.

Why fossil fuel power plants will be left stranded — By Martin Wolf | Financial Times

“Virtually all new fossil fuel-burning power-generation capacity will end up “stranded”. This is the argument of a paper by academics at Oxford university. We have grown used to the idea that it will be impossible to burn a large portion of estimated reserves of fossil fuels if the likely rise in global mean temperatures is to be kept below 2C. But fuels are not the only assets that might be stranded. A similar logic can be applied to parts of the capital stock.”

US Navy increasing combat lasers power to 500 kilowatt level by 2020 to counter ballistic missiles

Posted by in categories: energy, military

In 2012, the US Navy initiated the SSL Technology Maturation (SSL-TM) program, in which industry teams led by BAE Systems, Northrop Grumman, and Raytheon, among others, competed to develop a shipboard laser with a beam power of 100 kW to 150 kW by 2016.

Boosting beam power further—to something like 200 kW or 300 kW—could permit a laser to counter at least some ASCMs. Even stronger beam powers—on the order of at least several hundred kW, if not one megawatt (MW) or more—could improve a laser’s effectiveness against ASCMs (Anti-Ship Cruise Missile) and enable it to counter ASBMs (Anti-Ship Ballistic Missile.

By 2020, it should be possible to demonstrate a 250–500 kW laser weapon system, one appropriate for deployment on current surface combatants and capable of being a game changer in the Navy’s struggle to address the growing A2/AD challenge.

Taiwanese research institute is wrapped in an undulating skin of 4,000 aluminum fins

Posted by in categories: energy, innovation

Industrial Technology Research Institute (ITRI) is located at Central Taiwan Innovation and Research Park in Nantou, Taiwan. It is expected to become the central facility of the Science Park to be built in this region. Noiz Architects and Bio Architecture Formosana won the competition to design the building in 2010. During the development phase, the project site had to be relocated once during the design development phase, and the construction finally completed in September 2014.

DNV GL to Validate ARPA-E ‘Internet of Energy’ Microgrid in Texas

Posted by in categories: energy, internet

BURLINGTON, MA—(Marketwired — Apr 5, 2016)

DNV GL, the world’s largest resource of independent energy experts and certification, together with its partners, Group NIRE and Geli (Growing Energy Labs, Inc.), will produce and operate an Internet of Energy (IoEn) platform integrating the management of up to 100 distributed energy resources (DER).

The award, DNV GL’s third from ARPA-E, is one of twelve new projects in the Department of Energy’s Network Optimized Distributed Energy Systems (NODES) program announced in December.

Federal agency making waves in battery storage, energy tech innovation

Posted by in categories: energy, military

Whenever the military sets up operations in isolated and hostile locations like Iraq or Afghanistan, one of the biggest challenges is ensuring troops get reliable power.

Until now, that often has meant trucking in vast amounts of diesel to power generators, a strategy that isn’t all that environmentally friendly and is vulnerable to attack or other problems like a driver strike or mechanical breakdown.

But what if military bases could produce their own power?

Nanoparticles can grow in cubic shape

Posted by in categories: energy, nanotechnology

The efficiency of many applications deriving from natural sciences depends dramatically on a finite-size property of nanoparticles, so-called surface-to-volume ratio. The larger the surface of nanoparticles for the same volume is achieved, the more efficiently nanoparticles can interact with the surrounding substance. However, thermodynamic equilibrium forces nanostructures to minimize open surface driven by energy minimization principle. This basic principle predicts that the only shape of nanoparticles can be spherical or close-to-spherical ones.

Nature, however, does not always follow the simple principles. An intensive collaboration between University of Helsinki, Finland, and Okinawa Institute of Science and Technology, Japan, showed that in some condition iron nanoparticles can grow in cubic shape. The scientists also succeeded in disclosing the mechanisms behind this.

“Now we have a recipe how to synthesize cubic shapes with high surface-to-volume ratio which opens the door for practical applications”, says Dr. Flyura Djurabekova from the University of Helsinki.
