You should be thankful that Dr Y offered you his garage and his electricity for free!
I do not wonder why it is that the "rich people" as you call them, wont offer you any financial support..
Then you go on to say that a scientist has explained to you how to make a small gravity generator with off the shelf parts..I would have thought you should already know how to make one of those devices, if you have successfully already built a working time-machine as you have claimed!
And then you tell us that you will need a transistor radio (get one fitted with a Phase Locked Loop for stability) and a TV antenna coupled to an amplifier, those items are very cheap!..
As for the power supply, i thought that with your technical ability, you could build one yourself very cheaply..
I dont wish to appear rude, but you can certainly count me out of your funding, everything i have built has been done very cheaply, and i would expect you to do the same...
