Using Basic Math and Physics To Understand Bizarre Claims

Here’s a bit of discussion regarding this guy’s claim that a drop of water could produce 140 volts, sufficient to light up 100 LEDs.

Joel Schilling Truly an amazing idea. Water is everywhere, clean energy is a change in the right direction. If one only thinks about short term gains and has to destroy the planet for these means. That is not a solution to a problem, that only creates more problems. The goal should not be to make a profit, it should create opportunities and equal growth for all to share. New job growth , healthy cooperative investment opportunities, nationwide free trading for assistance to help health damaged areas around the world. Natural resources recovery projects funded by volunteers and investors alike. Where building friendship and sharing ideas becomes second nature to all. Equality and true love for one another. We are all a big diverse family let’s forgive our past mistakes and evolve together in the right direction. The future is indeed bright.
Craig Shields You note that “destroying the planet … is not a solution to a problem,” Correct. But neither is this. It claims that it generates 140 V of power. Volts are not a unit of power. That’s like saying I weigh 140 minutes, or 140 meters.
Ryan Chase Violates the conservation of energy. One drip of water will not light 100 led.
Craig Shields, Well, Ryan, another error in this claim is that it confuses power and energy. Theoretically, it could light 100 LEDs for an extremely short period of time.  For grins, let’s do the math, given that there are:
20 drops of water in 1 gram
2.5 Watts required to light a small LED
E (joules) = MGH = Mass (kg) * gravitational acceleration * height in meters (from photo, looks like 0.5 meters)
E = 0.05*9.8*0.5 = 2.5 Joules = 0.0007 Watthours
Now, Time = Energy / Power, so
0.0007 Watthours / 100 * 2.5 Watthours = 0.000002 hours = 0.00072 seconds or 1 / 1389 seconds
