The pump would still be there. It's just the two vavles that would be replaced. The actual piston would be (almost) the same in it's form and function.

So there would be no moving parts in the VALVES. The pump would still be a major, important moving part that would need to be serviced. But you are eliminating two points of very common failure with tesla's design.

If they were able to produce a prototype valve that was 5x to 10x the size of the one in the video, I might be interested in buying...

That is really really really cool. Videos do need audio though.

I should point out we actually do use the weak force for energy production, that is what is going on in the curiosity rover, radioactive decay of Pu238...but it is one of the lowest power conversion ratios that you can do for electricity production (thermocouple). They are just really simple with no moving parts, but it ain't going to solve no energy crisis! We actually have infinite gravity wells via black holes, @maestro156, but you still can't generate perpetual motion from it. I would like to hear your idea on how you could, though.

Those are very simple jet engines. No moving parts in those ones, and other pulse jets only need one valve. They made something very similar in the jet powered go cart episode of junk yard wars.

For all your home brew pulse jet needs

correction; inkjet printers are bullshit
only thing wrong with laser printers is the buying prize, but it also lasts longer
ink doesn't dry out on it's own like on inkjets
doesn't get stuck as often due to no moving parts on paper surface
drivers and general mechanical functionality don't suck as bad due to less complex mechanics
doesn't take fucking 30 minutes to install a new cartridge
used to install stuff like printers for a living for a while and hated anyone who got an inkjet cos it took so goddamn long to set up and then there still often was trouble with the inks - or drivers - or the mechanical parts being buggy or plain faulty
it took all of three minutes to unpack a laser, install drivers and plug it in
