Leaf blowers are unbelievably cheap now days.
Gasoline generators,
Kw-hr meters,
hand held wind speed meters and
other test equipment
have never been as affordable as now.

These things can be tested yourself, in the style of Mythbusters.

Should i be encouraged that people have strong feelings on these subjects,
Or discouraged that
the typical high school physics classes of today
appear to be very ineffective?

Past threads about tailgate up or down
Have sadly gone down the path of this one.
