Hi Dave,
Putting aside the degrees and the permits you should have
in order to start this project! Watch out what kind of batterys
you use. Alot of batterys have mercury in them even though
they are not called mercury. After several runs you will have
contaminated the area. Some capacitors have PCBs in them.
