This bridge and tunnel goes under water to allow movement of ships. In order for ships to pass, this bridge is half under the water. You drive down in the water and then come out on the other side. Truly a marvelous piece of engineering! This bridge is between Sweden and Denmark. Picture taken from the side of Sweden.
A
group of engineering students from Aligarh Muslim University have
succeeded in extracting bio-diesel from refined and used mustard oil,
university officials said on Tuesday.
Third-year students of
the Diploma in Engineering at the AMU Polytechnic designed a bio-diesel
extraction plant as part of the recently developed Alternative Fuel and
Combustion Engineering Lab, said M. Yunus Khan, assistant professor of
mechanical engineering.
The process can help in directly
replacing diesel in conventional engines, thereby reducing India's
dependence on imported oil and emissions of various pollutants,
officials said.
Bio-diesel is a renewable fuel derived from vegetable oil that can be an additive to or entirely replace diesel in engines.
