The objective of the project is to make an assistive limb to assist human beings in some or other activity, eliminating human errors and increasing productivity. The most common activity humans perform, be it a soldier or an industrial worker or a rural woman, is weight lifting and that is what we aim to target. The idea is to make an exoskeleton which will help human beings lift heavy weights without feeling any load/stress on the human muscle. The prototype made when worn by a human can successfully lift up to additional 40kgs with the one arm.
The exoskeleton is ...
Wearable Power Modules (WPM) is a modular solution to enhancing human muscle capability with clean engine power while batteries don't have enough energy density for heavy tasks. WPM is designed to collaborate with mobile data services (IoT/M2M) and extend wearable technology for power applications. Centerpiece of WPM is the ultralight power module (PM). PM outputs pneumatic power, it empowers various modular tool adapters. For mobility concern, it could be used for pneumatic powered bike, skateboard, wheelchair or exoskeleton; other applications could cover power hand tools, emergency rescue tools,sport equipment, etc. (Fig. 1).
The power module (PM) uses propane/butane ...

Expulsion is the molten metal ejected from the nugget under pressure, burning in the air with bright light and loud noise. Because the loss of liquid metal from the nugget expulsion always produces poor quality weld and it also consumes more than three times the energy needed to make a low temperature solid state weld. Majority of welding professionals believe you have to melt the metal in order to produce a nugget. I can easily prove this is untrue in the accompanying video. Fusion weld nugget and solid state nugget are different. The low temperature weld has invisible join ...
In India thousands of railways travel everyday from one destination to another. The engine is the most important device of railway and it works on the principle of conversion of heat energy into mechanical energy.
A large amount of heat is dissipated through the fins from the engine when it starts and runs. The idea is to utilize this heat energy to generate electricity that may be used to lightening, cooling fan, charging of mobile/laptops and other appliances.
The idea of energy efficient railway for transportation seems to naturally introduce the concept of using waste ...
