Hot Water Cooling


You might have read my earlier post regarding handling IT temperature, well, in this post I am bringing some new cooling technologies that use minimal power by using hot water to cool the systems. The heading may look like an oxymoron, but read further about some projects which have successfully implemented this technology. IBM’s SuperMUC LRZ SuperMUC system was built with IBM System xiDataPlex Direct Water Cooled dx360 M4 servers. IBM’s new hot water cooling technology directly cools active components in the system with coolant temperatures that can reach as high as 120 degrees Fahrenheit. So how exactly are they… read more

Hungry Electronics

Power consumption

Modern electronic gadgets have jaw-dropping functions making human life simpler in several ways. Their smartness can be seen in many ways such as speed, functionality, multitasking capabilities etc. but one main thing modern electronics manage well is power usage. Modern devices are not only highly functional but they are extremely power conscious. It has become mandatory for devices like tablets and notebooks to manage power cleverly, just like an electric car that goes to an idle state and consumes less power. Older gadgets lack this power-management capability as they only have two states – either On or Off. “Off is… read more

The Charge Cycle


Modern Smartphones can do millions of operations per second but they drink power from a battery like a vampire and we are constantly searching for a power socket to keep them alive. Due to this fast power decay, many coffee shops and hotels have power outlets which allows the user to charge their device when required but David Krawczyk & Navjot Kaur of New York have come up with a concept of greener and far healthier ways to charge your phone. The technology they have devised is the same decade old “dynamo” concept but the project is spiced with extra… read more

Underwater Sensors

Swimming with sensors

Scientific breakthroughs in nanotechnology have taken electronics to the next level by making the circuit smaller and smarter, but a professor at the University of California is proving that he can design circuits which can be pushed, pulled and even used under water. Thin film electrochemical sensors are directly printed on a flexible wetsuit by the team led by Joseph Wang paving the way for water resistive electronic sensors which has a potential application under water. With funding from the U.S. Navy and with the help of some members of his team who like to surf, Wang and team designed… read more

Acoustic Energy

Acoustic energy waves

While some of us get irritated by the noise, Jeong Ho You finds an innovation from it. Jeong Ho You, a mechanical engineer at the Southern Methodist University, says “Acoustic energy is everywhere”. With tiny resonating chambers, he wants to trap some of acoustic energy and convert it to low-amperage currents which can power small electronic devices. Similar to Ho You, Mark Sheplak, a research fellow at the University of Florida has worked with acoustic energy. In fact he has built an acoustic energy harvester for a NASA jet engine research project. He says “A lot of people wrote it off because there… read more

Bladeless Turbines

Bladeless Turbines

Wind power is one of the most popular and widely used sustainable, non-depleting, non-polluting and eco-friendly energy sources. Recent technological advancements are making innovations only in the grid and energy storage systems but meager updates in the case of turbine design which was initially designed 400 years ago. So what is the problem with the existing design? Well, there are three reasons; their efficiency is insanely bad, the cost of installing single turbine is very high and the most important issue is “wind turbine syndrome” where people in the vicinity of the turbines get headaches, sleeplessness and other health problems…. read more

Data Furnaces


There are many ways to hide from the winter but I recently read a paper presented in “Usenix Workshop on Hot Topics in Cloud Computing” that proposes the idea of using cloud server generated heat to warm up houses instead of a furnace or room heaters . This paper titled “The Data Furnace: Heating Up with Cloud Computing “ was co-authored by Jie Liu, Michel Goraczko, Christian Belady and Sean James from Microsoft Research and Jiakang Lu and Kamin Whitehouse, from the Computer Science Department at the University of Virginia. The paper puts forward the idea of dispersing the cloud servers amongst homes instead of having a… read more

Wind Powered Charger


Using an electric car is really cool and now there is yet another reason to be uber-cool, as the world’s first wind powered electric vehicle charging station was installed successfully last month. “Sanya Skypump” is a collaborative effort of Urban Green Energy and General Electric; it is the world’s first EV station which charges cars with the help of wind. Sanya Skypump uses the technology of both organizations – the vertical tower is from Urban Green Energy (UGE 4K) and EV charging technology is from General Electric. Together they form an all-in-one power generation and charging station. The vertical axis… read more

Reasons For Electric Cars


Electric cars were dominant in the late 19 and 20th century until the internal combustion engine was invented and gasoline was mass produced. Due to the recent petrol price hike and the limited availability of fossil fuels, electric cars have again grabbed the attention of many. The following are some reasons why you should consider buying an electric car. Electric cars contribute to health and the environment: As they use electricity as fuel, there are zero emissions. In fact electric cars don’t even have a tailpipe. By driving an electric car you are creating a healthy and quality environment. Green charging:… read more

Uranium Mining Underwater

Uranium Mining Underwater

The ocean has always inspired and supported the human race. We have navigated across them, tapped into their power for energy generation, exploited their creatures for food and minerals for wealth, and we continue to explore their depths for answers to our questions about the planet. Recent experiments have unveiled surprising amounts of uranium hidden beneath the waves. Oceans are estimated to have roughly 5 billion metric tons of uranium, which is a core element for nuclear power generation. The uranium deposits are very diluted and to date there has been no commercially viable method to extract the precious material. Uranium extraction from the ocean… read more
