Minnesota professor works on hybrid hydraulic project
MINNESOTA - University of Minnesota researchers are working on an alternative to the electric hybrid vehicle.
Hybrid hydraulic vehicles have recently been built as the new model for large vehicles that start and stop frequently, such as delivery trucks.
But mechanical engineering professor Kim Stelson says he hopes to develop hydraulic technology for small passenger cars.
Hydraulic hybrids store energy in the form of compressed gas, while electric hybrids store electricity in a battery.
Stelson says he'd like to test the technology by building a hybrid hydraulic Metro Transit bus. The funding for the project still has to be worked out, but Stelson says such a bus would get 10 miles per gallon as compared to about three that most buses get now.

Energy dashboard: how is electricity generated in Great Britain?
LONDON - Great Britain has one of the most diverse ranges of electricity generation in Europe, with everything from windfarms off the coast of Scotland to a nuclear power station in Suffolk tasked with keeping the lights on. The increasing reliance on renewable energy sources, as part of the country’s green ambitions, also means there can be rapid shifts in the main source of electricity generation. On windy days, most electricity generation comes from onshore and offshore windfarms. When conditions are cold and still, gas-fired power stations known as peaking plants are called into action.
