Q

What are three things you remember from chapter 3 or LCA 5 different technologies?

A

LCA emissions also contribution from tires and brakes.
We can reduce emission by having flatter roads.
Engine combustion uses heat and pressure to turn pistons that turn shaft which will spin wheels.
Peak efficiency occurs at 30-40 miles an hour

Q

Name 3 things that was relevant in the NTV video

A

Moved into groundwater and wells quickly.

At the surface MTBE was supposed to help burn fuel more cleanly. Just because a chemical is more “environmentally friendly” at combustion, this does not imply good medical implications. Lab rats got cancer

This led to more extensive testing of water. Examining for more harmful chemicals.

EPA awareness and plees made to congress to remove MTBE from gasoline.
