Look how interesting... And an airplane engine that uses microwave-induced air plasma. Such a jet engine simply uses only air and electricity to produce high temperature and pressurized plasma for jet propulsion. Demonstrated that, with the same energy consumption, its propulsion pressure is comparable to that of conventional jet engines of fossil fuel aircraft. Therefore, this carbon-free propellant could potentially be used as a jet propellant in the atmosphere. Fig1- Schematic diagram of a prototype microwave air plasma jet thruster. A flattened waveguide was used to increase the electric field strength of air ionization inside the air ionization chamber. Fig2- Images of the microwave air plasma jet at different power settings (in a unit of W). The length, temperature, and brightness of the flame increase with an increase in the microwave power. The flame temperature can reach higher than 1000 °C , 1832°F , 1273,15 K Fig3- Schematic diagram of a simple homemade heat-resistant device for the propulsion pressure measurements, consisting of a hollow steel ball on top of the quartz tube. The device has a small hole at the top for inserting smaller steel beads in order to adjust the threshold weight at which the ball starts to rattle due to the effect of the plasma jet. (b) The device used in the experiment, the point at which the hollow steel ball began to vibrate Fig4- Threshold propulsion force at various air flow settings as a function of the microwave power (in a unit of W). Linear fits were obtained with m representing the slope and c representing the y-axis intercept. I represents the air flow rate (in a unit of m3/h). (b) Similar to (a), but with the x-axis representing the air flow rate.

I made this little page on what I found orbiting. Come back later to see more, except with Kerbonuats involved (for doing research on the area I'm showing you guys). https://goo.gl/photos/V5jaYAkN8WCWNv5b6 Sorry about the external link, I couldn't figure out how to get it into the post. It wouldn't let me... Kerbals coming soon!

The rules are simple: Post a picture that people might not know what it is. Then, if the next poster, knows what it is, they will say what it is, and then they post another weird or obscure picture. If not, then they will say "WHAT IS THAAAAT?!" and the previous poster will tell them, and post another picture. This cycle will repeat until some gets it right. I'll start: (Note: it does NOT have to be KSP related. This is a Lounge sub-forum, isn't it?

Sorry I haven't been on in a while. Just dealing with life problems. While I was gone I thought, 'Hmmm so Deimos and Phobos are around the size of Mt. Everest and have gravity and that means if Everest was a space rock it would have gravity too... right?' Why is it that Everest has no gravity then? Well logic would dictate that Earth's gravity counteracts Everest's meaning Olympus Mons on Mars would have LOADS of gravity. Leave a comment on this idea.
