Energy & Propulsion

A fuel cell is a device that generates electricity by a chemical reaction. It converts hydrogen and oxygen into water, and in the process also creates electricity. Fuel cells provide many advantages, they are environment friendly as they don’t produce pollutants or greenhouse gasses, significantly improving our environment, high energy efficiency ( …

A directed-energy weapons (DEW) are ranged weapon systems that inflicts damage at a target by emission of highly focused energy, including laser, microwaves and particle beams. Potential applications of this technology include anti-personnel weapon systems, missile defense system, and the disabling of lightly armored vehicles or mounted optical devices   …

The Internet-of-Things is an emerging revolution in the ICT sector under which interconnecting physical objects communicate with each other and/or with humans over internet in order to offer a given service.  The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people …

Sometimes long runways  required by conventional aircrafts aren’t available to use or there is a need for an aircraft to use no runways at all.  Vertical take-off and landing VTOL technology means aircraft can theoretically take off and land almost anywhere, making them far more flexible. They’re also able to perform …

Ladakh accounts for more than two-thirds of the land area of the Indian state of Jammu & Kashmir. As a high altitude cold desert, though, it hosts only about 5% of the state’s population. With the mercury dipping to minus 20 degrees Celsius or lower during winter nights, and about minus …

Because of higher density chips, the design of more compact electronic components makes heat dissipation even more difficult. All advanced electrical or electronic devices are facing heat management challenges due to the increased levels of heat generation and the reduction in the surface area for heat rejection or dissipation. So …

Today U.S. soldiers are being killed because the Defense Department cannot deploy all the sensors it would like to. DoD could  deploy sensors every few yards to detect  buried  improvised explosive device (IED). As it is, every sensor deployed today has to be battery powered, so even if vast sensor nets …

Wireless power transfer (WPT) or wireless energy transmission is the transmission of electrical energy from a power source to a consuming device, without the use of discrete man-made conductors. WPT use wireless transmitter that uses any of time-varying electric, magnetic, or electromagnetic fields to convey energy to one or wore …

Microbial fuel cells (MFCs), generate electric energy by converting chemical energy from organic compounds through catalytic reactions by microorganisms. Microbial fuel cells (MFCs) are envisioned as one of the most promising alternative renewable energy sources because they can generate electric current continuously while treating waste. While these cells individually produce …

Scientists from Australia have produced the largest flexible, plastic solar cells, having 30 centimetre-wide panels and according to them the technology is close to commercialization stage.
