Efficient Air Conditioning Systems

Air conditioners have been cooling our homes ever since the discovery by Willis Haviland Carrier. The market of modern air conditioners, have seen a rise from the time when, it was only available to a few to this decade when almost each house has or wants to own an air conditioner. According to U.S. Energy Information Administration’s finding, the financial year of 2013-2014 saw a sale of about 3.3million numbers of air conditioners in India. The air conditioner market in40

University of Illinois Researchers Establish another Solar Cell Record

As per reports, scientists working at the University of Illinois at Urbana-Champaign have developed a new technology for increasing efficiency of solar cell systems. The research work used a printing process to assemble tiny cells into multilayer stacks for extraordinary levels of photovoltaic conversion efficiency. “A few simple ideas in materials science and device assembly allow us to bypass many of the limitations of traditional photovoltaic technologies,” explained John Rogers, part of the research group. This research could someday pave40

Researchers at University of Arkansas establish new Solar Efficiency Record

Researchers at the University of Arkansas have succeeded in achieving the highest efficiency ever in a 9 millimetre-squared solar cell made of gallium arsenide. A conversion efficiency of 14 percent was achieved after coating the tiny cells with a thin layer of zinc oxide. A small array of these cells can generate sufficient energy for small light-emitting diodes and other devices. The cells can also be easily be arranged in large arrays of panels in order to harness power for40


New technology could allow batteries to last as long as 50 years

Researchers have invented a new battery that can pave the way towards creating batteries that could last much longer than previously thought possible. A team of researchers at US Department of Energy’s Oak Ridge National Laboratory (ORNL) have challenged a long-held assumption that a battery’s three main components – the positive cathode, negative anode and ion-conducting electrolyte – can play only one role each in the device. As per the study that has been published in the Journal of the40

Trina Solar Limited Develops New High Efficiency Solar Module

As per a press release by Trina Solar Limited, the firm has developed a record-breaking, high-efficiency Honey Ultra solar module. Trina Solar’s Honey Ultra monocrystalline silicon module reached a new record of 326.3W and has been independently certified by TUV Rheinland. This is a new world record for p-type monocrystalline silicon modules. Honey Ultra marks the second generation of Trina Solar’s Honey module technology and this new high-efficiency record significantly extends the previous milestone of 284.7W attained by Trina Solar’s40

The Earth

People’s deaf ears to Earth’s silent tears

Earth is our home or rather, it is our only home. For the last two-hundred years, we have been trying our best to conquer nature. Now, we are beating her to death. For so many years, we have seen our fellow human beings plundering Earth. Sarcastically speaking, Earth is charred beyond recognition. Despite committing so many crimes and attempting to conquer Earth, we have failed big time. It is said that ‘fighting nature is fighting one-self’ and how true it40

Self energy audits for commercial consumers in Delhi

According to reports, the commercial consumers in East Delhi can now audit and analyse their consumption patterns. This will in turn assist them in taking steps to lower their energy bill and economise consumption.  The BSES Rajdhani Power Limited (BRPL) and the French major Schneider Electric have announced a strategic partnership to offer energy audit and energy-efficiency solutions for the consumers. India has the energy saving potential of around 20,000 MW; of which saving potential in Delhi is around 76040

Stirling Solar Dish

Stirling Solar Dish

Continued from Part 5 (This is a series of articles on the various technologies that can be employed to trap the sun’s energy. This is the 6th part of the series.) The stirling solar dish in outward appearance is just like the solar parabolic trough. It is also known as the dish engine system. They look like satellite dishes. It is made up of a single parabolic reflector unit which acting as a concentrator focuses light onto a receiver unit40
