An engineer and a historian discuss how technology and human behavior are shaping the sustainable energy revolution.

In the first in a series of events exploring the intersection of engineering and humanities perspectives on common themes, Stanford faculty members John O. Dabiri, professor of civil and environmental engineering and of mechanical engineering, and Ian Morris, professor of classics, engaged in a moderated discussion about the future of sustainable energy. The two spoke at length about their different viewpoints on a central question: What can we expect the transition from fossil fuels to renewable energy to look like in light of new technologies and age-old human behavior?

Morris, whose most recent book explored the role of energy in shaping inequality and violence over the past 20,000 years, said that the three critical periods of energy transition – from foraging to farming to fossil fuel societies – have resembled the messy process of natural selection. “Changing our behavior is a process driven by the same forces that drive biological evolution,” he said. “We respond positively to things that allow us to do what we want to do in an easier way without taking too many risks. So if you have electric cars that cost less and run on less than internal combustion engines, then people will buy them. If you don’t, they won’t.”

Dabiri, whose research focuses on new ways to capture wind energy, said that engineers should think a little more about the context of their work – how renewable energy solutions will look different in Palo Alto than they will in Mumbai – as well as how a deeper understanding of human nature could help motivate people to change their behavior. “We often as engineers come in to the problem thinking if we come up with a cool enough gadget, people will flock to it. That might be true of the iPhone,” he said. “Until we come up with the iPhone equivalent for climate change, for solar energy, for wind energy, it’s going to be an uphill battle for massive adoption of these technologies.”

Video tutorial on how to remove the anti shudder valve (asv) on a VW Golf, Jetta, Bora, MK4 TDI PD BEW engine. Some other models that came equipped with a PD100 included some Skoda models, Audi models, and VW Passat. After a while of operation, the anti shudder valve does build up with dirt and debris which does need to be cleaned. Anti shudder valves can also malfunction over time either getting stuck open or closed, therefore not allowing the engine to start. The original function of the unit shudder valve is to prevent a “run-away diesel” and to allow for quieter engine shutdowns. This particular tutorial was done on a 2004 Volkswagen Golf TDI.

Tools/Supplies Needed:
-interlocking pliers
-allen wrench

Procedure:
-first remove the engine cover by pulling straight up on the two front corners, once it’s release pull straight towards you
-next remove the boost hose from the plastic tube and then from the anti shudder valve
-remove the clamp on the plastic tube side using the interlocking pliers by squishing the tabs and moving it off the rubber hose
-pull straight out of the anti shudder valve, ensure that you disengage the snap ring
-remove the three allen head bolts, two are visible on top and the other is hidden underneath of the unit
-remove the anti shudder valve from the intake
-disconnect the electrical connector from the anti shudder valve motor unit, there is a tab on the side that needs to be pulled back to disengage it from the clip
-all allen head bolts are the same length
-when reinstalling, ensure the mounting faces are clean
-installation in reverse
