The design of the final support system became evident that using one tripod as a base was too weak. Using two tripods with a cross beam would work much better. However, in order to store more potential energy we wanted to add height. We decided to add long PVC pipes to the tripods. We used PVC for the cross beam and 90 degree PVC pipe attachments to create the final structure. Screws were installed into the 90 degree attachments to make them even more secure. Then, to reduce the movement of the vertical PVC, rolls of paper were coiled around the tripods–under the PVC pipes. This was done at the top and bottom of the tripods. The final design looked sturdy and was around 15 feet high.

The motor was a difficult to deal with. It worked well, but it was on a big block of wood that could not be placed anywhere very well. We created a slimmer piece of wood, but still did not know what to do with the motor. On the prototype, it was placed on the top of the structure, but installing it vertically on the lower part of the structure made it easily accessible. After testing it was concluded that it would be smarter and not less problematic to simply put it on the top as it was designed to be.

    The final addition to the structure was a hook that kept the weight at the top.  The locking system works only when the weight is at the top. There is a clip on separate wire that meets up with another clip near the bottom of the structure. By clipping the weight, potential energy is held until the user wants to unclip the weight and turn it into kinetic energy.
