Experimental Null Test of a Mach Effect Thruster The Mach Effect Thruster (MET) is a device which utilizes fluctuations in the rest masses of accelerating objects (capacitor stacks, in which internal energy changes take place) to produce a steady linear thrust. The theory has been given in detail elsewhere and references therein, so here we discuss only an experiment. We show how to obtain thrust using a heavy reaction mass at one end of our capacitor stack and a lighter end cap on the other. Then we show how this thrust can be eliminated by having two heavy masses at either end of the stack with a central mounting bracket. We show the same capacitor stack being used as a thruster and then eliminate the thrust by arranging equal brass masses on either end, so that essentially the capacitor stack is trying to push in both directions at once. This arrangement in theory would only allow for a small oscillation but no net thrust. We find the thrust does indeed disappear in the experiment, as predicted. The device (in thruster mode) could in principle be used for propulsion. Experimental apparatus based on a very sensitive thrust balance is briefly described. The experimental protocol employed to search for expected Mach effects is laid out, and the results of this experimental investigation are described. Suggestion from Advanced Space Propulsion Workshop in Huntsville Alabama for a null experiment. If we were to place identical brass masses on either side of our active PZT stack, then the mass fluctuations would result in pushes and pulls of equal magnitude and the device should just oscillate a little but show no average thrust. This appeared to be worth testing. It would show that we were able to eliminate any unwanted vibration, noise effects.

Meridiani Journal - Astronomers redefine the habitable zone for exoplanets. Astronomers, from Penn State and also collaborators with the Planetary Habitability Laboratory, have concluded that, overall, the habitable zones are a bit farther out from their stars than previously thought. "This has implications for finding other planets with life on them," according to Ravi Kumar Kopparapu, a lead investigator with the new study.

This was accomplished with a simple substitution of tetravalent silicon into the magnesium atomic sites. The chemical formula thus becomes Tl5Pb2Ba2Si2.5Cu8.5O17+. This is the third material discovered with a critical transition temperature (Tc) above room-temperature. Joe Eck is a lone researcher who has had some previous work published in smaller journals and some other researchers have copied his work and had them published. He detects magnetic transitions that indicate likely superconductivity but the material has a low percentage of superconducting material and needs to be processed and purified. He has not been able to get the interest or cooperation of larger institutions. Joe has also done work to improve the formulation of YCBO superconducting materials Multiple magnetization tests were performed on two separate test pellets to confirm this exceptionally high Tc. The highest and lowest measurements on the first sample ranged from 37.1 C to 35.8 C. The second pellet produced diamagnetic transitions between 37.5 C and 35.5 C. The average of all the tests was just under 36 Celsius. The flashing lines in the two plots at page top represent the average of the noise component skewing apart near 36 C in both warming and cooling test cycles With an ionic radius smaller than magnesium (0.4 Å - vs - 0.72 Å) silicon will occupy the same atomic sites in the "Light" region of the C1 and C2 axes as magnesium does. This is illustrated in the D9223 graphic at left with an arrow pointing to the Si-Cu plane. Though the planar weight ratio is lower with silicon than with magnesium, the Cu02 planes clearly benefit from being electron-doped. Below is the plot of a second sample pellet, synthesized and tested three days after the first pellet. The plot again shows an unambiguous diamagnetic transition just below 36 C. Resistance tests were not possible with this formulation, as the non-superconductive bulk material is an insulator at room-temperature. A measureable bulk resistance is required to observe a resistance change resulting from a minority phase.

The Wang Bullet is a single pulse nuclear external pulse propulsion system. Freeman Dyson and Ted Taylor and others worked on the project Orion nuclear pulse propulsion system. The designs involved about 200 pulses to get out of the earth's gravity and 600 more pulses to go to Mars or Saturn's moon Titan. The single pulse propulsion system is to dig a large hole and use one pulse which is a nuclear cannon that could launch thousands of tons in one shot. In this article, the reports from past nuclear tests is used to consider if the blast size and the projectile could not be configured for a successful launch. They also consider nuclear blasts for excavation. Tsar Bomba Boiled (vaporized) Rock? I wrote Goat Guy:  your recent comment concerning  Boron and H-Bombs  got me going---http://nextbigfuture.com/2012/02/which-is-cheaper-per-unit-of-energy.html "THE thing that scuttles this isn't the cost of the nukes, nor the added-load of nuclear fallout in the atmosphere (a political problem more than anything), but the consequence of the nuclear explosions to the payload.  They would be positively drenched in neutrons with every shot.  Now, one can go all yada-yada "boron", etc … assuming that one might be able to absorb most of the neutrons. Aux Contraire, me hearties.  Neutrons, especially in "spikes" are really good at lighting up absorbers such as boron into resonant states that no longer absorb (on nanosecond time-scales) more neutrons. What you'd get by the time the big tub  got to space … is a highly radioactive wastebin of heavily transmuted "stuff".  Electronics would be fried.  Metals would be permanently radioactive.  This is not what would be "the point". Further, instead of wishfully thinking about using megaton-or-larger devices to get around the cost, please recall that if small-kiloton blasts (0.5 to 10 kT) could barely be sustained by the pusher-plate due to blast-spallation effects, then 100 MT is right out.  There are no known materials that wouldn't just vaporize to plasma in 10-meter-thick layers at modest proximity to such blasts.   The 1 km wide, 100 m deep pit left after the air-burst of the Tsar Bomba at only 50-60 megatons wasn't only "compressed dirt".  nearly half the mass was vaporized entirely.  Instantly. The whole idea is an intellectually stimulating thing, but a practical nightmare.  And that's the problem.  Not to mention the elephant-in-the-living room."   Read more » • Email to a friend • Article Search • Friedlander Cold Crown 2: A Conversation With Goat Guy A guest post by Joseph Friedlander for Next Big Future The reader known as Goat Guy is a regular in the talkbacks at Next Big Future, many have been entertained by his opinions, backed up by hard engineering calculations. This is a follow up examination of the Friedlander Cold Crown and managing large scale lunar industry. The purpose of the Friedlander Cold Crown is to capture runaway gas escapes that otherwise would ruin the wonderful Lunar ambient vacuum during a period of massive industrial bootup. For current lunar atmosphere, Landis gives ten million molecules/cubic centimeter (half nanotorr) during the lunar day 100,000 molecules/cubic centimeter during the lunar night, This corresponds to pressures from 0.001 nanotorr This is good enough to use vacuum tubes without the tube, a vacuum technician's paradise easily spoiled by large scale outgassing.  I had a correspondence with him about the Friedlander Cold Crown whose purpose is to capture runaway gas escapes that otherwise would ruin the wonderful Lunar ambient vacuum during a period of massive industrial bootup.

(3 ways to get rid of heat, conduction, convection, radiation is the least efficient use of surface area of the three) Read more » • Email to a friend • Article Search • More Recent Articles Improvement over TCP would give 30 times faster file transfer, 6 times less latency and 5 times faster web browsing Towards defect-free graphene and large scale manufacturing Genetically modified tobacco plants produce antibodies to treat rabies Towards Printable photonic devices with sub-10 nm resolution Enzyme Molecules as Nanomotors
