Thorium the Fuel of the Future to Revitalize Nuclear Power GenerationBy Rathindra Nath Biswas
Abstract: After disasters like Kyshtym, Windscale, Fukushima, Chernobyl etc., nuclear energy carried a dreaded stigma. The cost of nuclear power generation in the conventional way is on the rise, and so there is a resurgence in nuclear technology using thorium as fuel. There is a great pressure from international community to reduce carbon emission. So many countries are looking for a path to generate energy that is distinctly different but pays …

AEROGELS – A VALUE ADDITION TO HARVEST SOLAR ENERGYBy Rathindra Nath Biswas
Abstract: Aerogels are a class of synthetic porous ultralight material that was created in 1930 and derived from a gel, in which the liquid component has been replaced with a gas without collapsing the gel structure by freeze-drying. It is made of silica, but carbon, iron oxide, gold, copper, polymer etc. can also be used. During freeze drying the liquid in the gel is slowly dried off without collapsing the solid …

Solid State Technology Reinvents Microwave HeatingBy Rathindra Nath Biswas
Abstract: Since magnetrons first came into widespread commercial use in microwave ovens in the early 1970s solid state technology has evolved relatively slowly to be used in industrial heating, consumer cooking, drying, automotive applications etc. Recently, RF energy utilizing solid state devices has appeared in the market as a viable replacement for magnetrons as the heating engine. This route offers many advantages like better energy direction control, longer life, enhanced reliability, …

Plasma Tweeter Loudspeaker - A Singing ARCBy Rathindra Nath Biswas
Abstract: Plasma arc speaker is a loudspeaker that generates sound without a solid diaphragm by varying the air pressure and utilizing a high voltage arc. It makes sound by heating air that causes air to expand in the same way as in thunderstorm. The grumbles and growls we hear in thunderstorm come from the quick expansion of the air surrounding the lightning bolt due to sudden increase in temperature. This produces …

Portable small nuclear reactor for supplying Power to remote placesBy Rathindra Nath Biswas
Abstract: Los Alamos National Laboratory, USA has developed one very light and small sized modular portable nuclear power plant. It can be transported to remote places either by truck or cargo plane or boat and installed there within a couple of days. It can provide readymade plug-and-go power supply at war front, disaster site, remote islands etc. with a very low sound signature. Due to use of heat pipes and other …
