A team of mechanical engineering students of RV College of Engineering, Bangalore, has designed and developed  a car that does almost 250 miles to a gallon in test conditions. They have achieved this by making the car  aero-dynamic and extremely light weight.The car has a a low power 97 cc generator engine of two horse power.
They are calling this Project Garuda. Thier aim is to build a super milage single person car. Their plan is actually a  single person 4 wheeler. This is for the extra safety provided by the four wheels. The driver …

World over sewage treatment plants are fighting algae bloom, when this algae can be effectively harvested and processed to obtain valuable oil that can be converted into Bio diesel.

The complicated part of this process is the separation of algae from water which currently has been made easy to a large extent.

Sewage treatment is done in different steps and the algae problem comes at around …

The trouble, of course, with that, conceptually, is that lipase is a complex protein, difficult and expensive to synthesize. Naturally it would not be a significant breakthrough if Ravichandra did not start thinking “outside the box”, so to speak. He saw no reason to go to the trouble of refining the enzyme to …
