What is the potential energy for an elevator of mass 710 kg at the top of Chicago’s Sears Tower, a height 520 m above street level? Let the potential energy be zero at street level.
Take the free fall acceleration to be g.

How can we utilize Tesla’s free energy tower idea to make a practical machine supplying wireless energy?
I want to make a small version (only if it would be easy) to get free wireless energy for at least a couple acres of range. I haven’t done that much research on his invention, so sorry if this seems very impractical. If you can give me step-by-step instructions on how to do this, and it works, I’ll give you 10 points! (I was only a little sarcastic.)

Will running a homemade wind turbine without a load hurt it?
I’m in the process of building my first wind turbine and was curious if running it without a load (ie. battery bank) would be harmful to the generators? I’m using a 260VDC 5A permanent magnet treadmill motor as the generator. I’m about ready to put up my tower and wasn’t sure if I can go ahead and get it all assembled and put up and then add the battery bank as soon as I can get the batteries. This way I could also see how well it’s going to perform on the tower. It’s a 60′ lattice tower and will be hinged at the bottom but still will be a bit of a pain to lower and raise a lot. I’m really excited about getting this up and running but don’t want to damage anything before I even get started.
Also I’ve heard of people using old electric baseboard heaters as a load dump when the bank gets fully charged. I’m having some trouble locating any of these around here and was wondering if anyone would have any other suggestions on something I could use as a dump? Thanks for all your time.

how to regulate dc motor generator to 12v battery?
Here is what I have 10 foot wind-tirbine, 40 foot tower,24vdc perm magnet motor, six 12v truck batt connected parallel.
its all set up and functions well with a autonotive generator(not altanator) ond app automotive voltage regulator.However doesnt produce enough power. and i have changed the automotive generator to a 24vdc perm mag lil racale motor. and my question is HOW DO I REGULATE THE VOLTAGE AS TO NOT OVERCHARGE THE BATTERYS I need to make a voltage controler or modify other inexpensive means or other inexpensive aplications. thank you in advance
