    Lightning in a bottle

    You hopefully realize that you and the can will reach an equilibrium of charge and great care must be taken when removing rubber boots or making your next handshake. Could be a whole lotta shakin goin on.

    Potential energy of suspended mass expressed in kWh

    Indeed. I try to maintain a pair of swamp buggies for just such muddy situations. I have a friend who believes it could be helpful if the term billion was stated as 1000 million. He believes the non-math folks may have a better comprehension of the actual value. A trillion termed as "a million...

    That is a bit of the rub. I desire to induce the strikes into a 40 m² area, and if another strike is coming rapidly, it will have to be diverted to a different 40 m² collector pad, some 1/4 mile away. I don't foresee myself bankrolling experiments on this system unless a financial windfall blows...

    Don't touch the can, you'll botch the experiment.

    Let's use the corresponding formula and/or just let the sheet fly and take physical readings.

    Potential energy of suspended mass expressed in kWh

    Absolutely correct. So, when using SI units, the user obeys the SI convention and enters 1000 kg as 1000, and derives their result, never looking back, and looses 3 decimal places. Now if the original formula reads U = mgh and explicitly and in no uncertain terms states that m is to be expressed...

    Capturing the electrical energy from a lightning strike is no big ta-do. It's getting the bolt to strike where you need it to. If that's not enuff headache, ya gotta produce one out of clear skies. How bout a nice big hot cup of ionized gas to settle your queezies?

    Potential energy of suspended mass expressed in kWh

    Yeah, my buddy said maybe use ergs but I was unfamiliar with unit 10e-7 something. So, if I have my calcs correct, I derive what seems to be a nonsensical conclusion. I am told it is because of unanticipated scaling problems. I'll look that phrase up later. Given: AA battery; 1.2V, 2800mAh...

    29.4kJ is a bogus result that will not die, apparently. 1Mg X 9.8 X 3 = 29.4MJ

    Potential energy of suspended mass expressed in kWh

    Lost? I was thrown somewhere between Narnia and a bad acid trip when I received the following reply to my question regarding potential energy of a one tonne mass suspended 3 meters above the Earth's surface. I rounded the value to 0.002 kWh which = 2Wh. Trying to visualize and understand the...

    I think your opinion makes sense but the physics' department has a limitless vault of details and bs with which to dazzle and baffle you. Please read post #49.

    You get no argument from me. Tell it to these guys.

    Potential energy of suspended mass expressed in kWh

    Here is the skinny. Those that prefer to work in SI units know to change an actual real mass of 1000g to 1g in their working formula. What has not been mentioned by those same people is that the results of their calculations need an adjustment of adding 3 to the exponent of their result...

    Probably matters to missile guidance systems but that's not my concern.

    What percentage of error are we talking over entire g range discrepancy seeings how discrepancy is a magnitude of 3 away from more result determining values.

    Potential energy of suspended mass expressed in kWh

    Let me convert a little. 0.00817kWh = 8.17Wh. Matching quantities pretty sure. One of my LED light bulbs draws 9W. Therefore, the energy to elevate a tonne 3 meters, in an hour, is equal to the power required to illuminate my 9W bulb for one hour, approximately. Seems unfair. I request that I...
