Once again too little time
All too often first reaction of almost everyone, is why something won't work, or sounds too complicated, or too much expense for too little gain.
These are important to any process, but in a lot of cases good ideas never see the light of day, and i would think that "fear of rejection" is high on the list of reasons why ideas don't surface until hard times. (now off the stump)
Two ideas i have been preparing to work on (gathering materials and parts) but always too many other things that require first attention.
1. Consider a multiple of smaller motors (example 10 PM/DC 3hp units). Without going into all the pros and cons, these offer some variations that can't be produced with a single motor. They can all drive a common jackshaft and produce about 30hp, easier to keep cool, and a grouping of 2-3 or 4 can be run in reverse mode, with the use of clutch bearings, and Thur a much greater gear ratio, can be 0-7 or 8 mph , then at a proper speed a next group can take over etc. this mixing and matching offers a lot of possibilities, and some fun if you do enjoy mechanical engineering. At full forward speed they will be running in same direction, and sharing the load.
2. Designing a lead acid battery that is new and different, maybe not as powerful, or efficient as current design, but almost totally immune to failure, should be a worthy challenge.
My starting idea is to have a large PVC water pipe (8" or larger, very thick walls) and each end being lead plates with very good seals. One side is positive and the other negative. Through bolts of stainless steel carry current to the proper end plate. The quantity of bolts will depend on how much current needs to flow, and they will be insulated at proper locations depending their polarity.
Number of cells will determine voltage, and these can be a section of ? size filled with pure lead shot, as sulfating builds, the cylinder will be turned and the tumble action of the shot will produce a clean and maximum working medium for the battery.
With fluid circulation the battery should be able to sustain a much greater rate of charge, and discharge, than standard designs.
All cell seperators will be of material nonconducting and uneffected by sulfuric acid, and resistant to the shot tumbling.
These ideas might not work as well needed in the manor presented, but they should serve as a start point to change where we are with all the exotic, and high price applications now being considered.
Hopefully i didn't just kill another good thread, think i remember someone else talking about thread killing.
