What’s red on the outside and green on the inside? London’s new hybrid buses

While I am a big fan of diesel-electric hybrids, I would prefer that they use hydraulics instead of batteries. Hydraulic systems can deliver more than 10 times the energy storage of a battery and disposal of hydraulic fluid is much easier than a modern battery. http://economicefficiency.blogspot.com/2008/12/big-green-trucks.html

Several trials are on-going with vehicles like this bus. Competition is a good thing! Let's hope to see hydraulic hybrids enter the race for cleaner transportation soon!
