Instead of solar and cialis mail order uk wind power to supply to cialis canada generic your own house - which are both weather dependent - has anyone thought about systems that might require some actual work, but provide a usable amount of power?
I was thinking, what if each member of my family
carried a 40lb bag up 3 floors and hung it on a hook that was connected
to a generator; would an effort like that actually provide a
significant amount of energy? Just a thought.
Oh Jens...you don't even know what you've done! Your question is totally a word problem from a physics exam. And as much as this will likely frighten most people reading this, I'm going to treat it as such.
If 120 lbs is lifted thirty feet and then allowed them to drop slowly over twelve hours, how much energy will be produced?
120 lbs * 30 ft = 3600 ft/lbs = 4880 joules = 1.356 watt hours / 12 hours = 0.113 watts.
So, in answer to your question, no, that would not provide a significant amount of electricity. In fact, in order to power one 60 watt equivalent CFL for twelve hours, each member of your family would have to march up the stairs about ten times.
But that doesn't mean that you don't
have an excellent point. Every person is viagra australia a magical little energy
factory. Whataburgers go in...watt hours come out, and it is possible
to harness that energy.
