It will contain the construction of an emmision free engine.
Propulsion based on this theory ( gravity). In fact it looks simple and easy to build and knowledge allready excist.
Whats missing is the execution. At the beginning the thrust will be very low ( maybe micro grams instead of pounds) but its the beginning.
Any help is usefull. This theoretical engine might not be finished in my lifetime ( The concept engine could) So care for the future?, want to be a part of it?
Let me know. Just imagine being part of building the first gravity engine. That would be great.
