What Technology Is Used In Mechanical Engineering?

How can Science, Technology, Engineering, and Math be used to promote a clean, green lifestyle.?

• Answer:

  If you don't understand the science and technology, then you are stuck with assuming that everything that sounds cool or that you read about in magazines is actually what it is promoted to be. One example is the new (and expensive) reuseable baby diaper with disposable liners. they are advertised as a way to keep the solids (mostly the paper liner) out of landfills, because you just flush them. In actuality, solids are screened at the wastewater plant and sent to the land fill. But lots of people who want to be "green" have no idea what is really going on, so they are duped, and the manufacturer makes more money. Or the CFL bulbs that are heavy in mercury. it would be better to go with zenon or even LEDs (they will be commercialy available and inexpensive within 2-4 years), but our government (in the US and the EU) pass laws requiring the mercury contamination, because General Electric and Sylvania paid them money to pass the laws. Many so-called "green" options are really wastes, but since most people are so ignorant about the math and science, we do more harm than good.
