Energy

During conversion/transformation, some energy gets wasted. But a team from MIT has created an electrochemical cell that can convert waste heat into electricity.

If you switch on a laptop or a phone that was switched off at a stretch for a long time after a full recharge, you will find that it doesn't contain full charge. So where did the charge go? For long time researchers have been trying to find out an appropriate and acceptable answer of this question and now the researchers at the US Department of…

We often use network devices to connect multiple electronic devices at a time for different purposes. But lately, the International Energy Agency (IEA) has revealed that the networked devices waste 400 terawatt-hours of energy annually.

Nearly all major power plants release heat or steam as part of their functioning. While some recycle and use this heat, others waste it. In US, a mere 12% of the electricity is generated from recycled heat. And that needs to change now.

China has long been accused of backing its army of hackers in their numerous cyber espionage attempts. A report now reveals that Russian government may be playing a similar role, supporting a group of hackers who have targeted hundreds of energy companies globally.

As the energy consumption increases rapidly with each passing year, scientists are desperately seeking effective, new energy storage methods. An oft-ignored group of organic compounds called quinones may hold the ultimate solution.

Nuclear fusion research has been going around in a number of labs around the globe. Scientists hope that one day, nuclear fusion will be a key source of energy for us. Now, National Ignition Facility (NIF) in US has been able to achieve a breakthrough by creating more energy from a nuclear fusion reaction than was absorbed by the fuel used.

Can you remember last when a Compressed Air Energy Storage (CAES) plant was commissioned? It was in 1991. However, this week startup SustainX has brought the technology back to the U.S. electricity grid, albeit in a vastly different form.

For decades, Lockheed has invested on Ocean Thermal Energy Conversion (OTEC) in which the temperature difference between warm surface water and cold deep water is leveraged to produce electricity. Now, Lockheed is partnering with a Chinese resort developer to build a 10-MW pilot plant off the coast of southern China.

Every mobile needs to be recharged to keep it active. But it usually takes hours to fully charge the phone. An 18-year old Indian girl named Eesha Khare has made such a device that can fully recharge your cellphone just in 20 seconds!
