With all due respect, development of oil sands is a different discussion. However, as with the production of anything here in the West, nowhere compares with our environmental controls, (maybe Europe?) fines, penalties, etc. Whether E15 or E10, or production of gas, energy producers are under intense scrutiny. Most troubling is aquifer depletion, and mandated compliance for two wheeled vehicles that even in year round climes, are infrequently seen tooling down the road. It is quite likely the introduction of water cooling to the GS has less to do with cutting edge cool needed technological development, improving the breed, than it does to complying with the ever increasing across the board sweeping vehicle emissions law. Cross thread to the water cooled GS, where it was mentioned 7000 BMW engineers, including their automotive division, in the development of motorcycles. And after E15 there's the benefits of E20.
