Sustainable Technologies

Demand of fossil fuels used for energy generation is growing, resulting in emissions of carbon dioxide and other contaminant particles. In the last twenty years the global primary energy consumption grew 45% (BP 2011), increasing emissions of carbon dioxide between 1993 and 2011 by 44%.

We transform post consumer plastic waste to manufacture plastic lumber; this plastic lumber is a durable and affordable alternative to timber, which reduces the need for building material manufactured from wood. This helps to preserve forests by lowering deforestation rates and decreasing the effects of climate change.

My concept provides a much faster fluid flow mechanism into or out of a control device. The device could be hydraulic, pneumatic or any other fluid that must be controlled precisely.

Servo valve operators typically perform this function. However,

Internal combustion engines suffer from fairly low efficiency (internal thermal losses and wasted hot exhaust enthalpy). Small-scale engines' surface area/volume ratio combustion chamber leads to higher heat transfer losses and inefficient combustion. Furthermore,

As we know, the world population is increasing day by day. As the population increases, the increase in requirements results in lack of resources. The leading problem is pollution from which the whole world is suffering. Most of the air pollution is caused by automobiles, trucks, buses, etc.


World is looking forward to increasing electrical energy generation through renewable energy sources. Solar thermal has fallen way behind solar photovoltaic due to WRONG belief that it is inefficient.

Communication is one of the most important aspects of human life. The world has been turned into a global village after the integration of communication technologies with the Internet. And of all the different communication technologies available, email is considered as one of the most pervasive forms of communication.

This design concept provides a key component of a solar concentrated combined heat and power (CHP) system for saving primary energy consumption in cold climate zones.

Waste management has become one of the crucial concerns in today's world. One of the best ways to handle it is to segregate waste at the primary level. This model deals with segregating dry, wet and metal waste using a low power msp430 microcontroller.

Wind power has become an important source of renewable energy. We often hear and see many types of windmills where innovators are seeking to reach the highest possible efficiency and provide greater electrical energy.

But is it possible to produce water in addition to electric power by wind power?
