I have been working on a small side track project under my Maxwell's Engine thread.
This project, Build5,
forum (you may need to right click on the link and choose open in new tab) is showing some very interesting test numbers.
I have started to calibrate a new generator part as well as a new drive motor so that I can have beter data. I am also developing a NOW model that predicts the system and can be used to design a complete system.
So far the test bed numbers I have and the NOW model follow each others trends and tendancies fairly close, but there is a lot of noise in the readings, hence a new build with beter parts.
