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.

Renewable electricity powered California just shy of 100% for the first time in history
LOS ANGELES - Renewable electricity met just shy of 100% of California's demand for the first time on Saturday, officials said, much of it from large amounts of solar power produced along Interstate 10, an hour east of the Coachella Valley.
While partygoers celebrated in the blazing sunshine at the Stagecoach music festival, "at 2:50 (p.m.), we reached 99.87 % of load served by all renewables, which broke the previous record," said Anna Gonzales, spokeswoman for California Independent System Operator, a nonprofit that oversees the state's bulk electric power system and transmission lines. Solar power provided two-thirds of the amount needed.
