Although there may be some cheap surplus sets available we might have more access to, depending on what you want to do. Okay. Some lab measurements may be useful enough to work out a preliminary, safe regime --basically need to work out a reasonable picture of the resonant characteristics of a passive system --a kind of power inducing cavity-dielectric resonator set --without operating the unit by working with subcomponents. Assuming the full unit has the potential. Water replaces oxygen and hydrogen as the stored fuel. Microwaves heat water vapor, separating the O-H2 bonds, and a nearly continuous spark keeps the mix burning. Interesting! Let us know more when you can. These experiments ought to have emissions testing for safety, since the scaled versions of the two high-Q resonators and power induction apparatus might emit significant microwaves (and RF in the case of a full-size unit). Yeah, that's probably an excellent idea. Is this all at 2 GHz regime? or? I guess multi-band since the theoretical resonance would cycle between 3 different primaries (each with two oscillating frequencies due to the dielectrics). Perhaps somewhere in SHF for testing (fractional size), with the higher limits depending on dieletric resonant properties. A full-scale unit might work in UHF. In 2 or 3 weeks I should have a conceptual design document with initial requirements, specifications etc. cheers, BenB ___ psas-avionics mailing list psas-avionics@lists.psas.pdx.edu http://lists.psas.pdx.edu/mailman/listinfo/psas-avionics

Re: [psas-avionics] testing resources
Hi Ben K, Water replaces oxygen and hydrogen as the stored fuel. Microwaves heat water vapor, separating the O-H2 bonds, and a nearly continuous spark keeps the mix burning. The design will be published with the TAPR Open Hardware license[1], so there will be plenty of sharing in due time. I'd like to have a proof of concept before publishing, if only to keep the noise low and minimize wasting other's time. Dream: Given that the Google X prize moon competition is closed, perhaps Oregon State school system joins forces with an existing team? Or beats them all there! cheers, Ben 1. http://www.tapr.org/OHL On 09/08/2012 03:45 PM, Benjamin Kaplin wrote: Care to share more about this propulsion technique? --bk On Sep 7, 2012, at 8:36 PM, Benjamin Brink wrote: Hi, Does PSAS have access to the PSU Microwave Lab?
