and I bet was super efficient as well, nice one

way to go

Yes sir and thanks. I believe Kev has just such a plan in mind. It is incredible how careful design can yield high efficiencies. Keep up the log burning faith John

Yes sir. Good material

seems fine with a normal broom or sponge. Very hard and resilient to scrubbing

Greetings to you. Intricacies of the youtube algorithm remain a mystery to me too. I am recording classes because we suffer from poor attendance in the UK and by sending students the youtube links they see what they are missing and hopefully encourage better attendance regards John

​@@woodowoods9167and here I am where I can't even go to school for my parents' political stance on the monarchy (Morocco) you got proper labs and everything, what a shame the attendance is low 😢

I am honoured to have you on my course

Yes sir. It is a solenoid connected to a diaphragm

@woodowoods9167 no , its not, there is no diaphragm just a steel ball one way valve, that's why they are so noisy

I stand corrected, thanks for making me look at it.@@Dirt-Diggler

I know! I must confess all my videos are like this and I should consider editing them John

Agreed sir. Just a test rig at this stage

Sorry. see kzbin.info/www/bejne/q4rPeKGdibmtj80

Hello Rocketboysmc Yes. Two hour test flight with only a big enough battery for 8 minutes. Battery fully charged on landing.

@@woodowoods9167 Sounds like it worked well. Do you plan to upload the footage of the flight?

Didn't video it, but will again once the spring comes @@rocketboysmc

what do you mean with "first experiment of the Ion Drive"??? they were already used in missions like the DART mission en.wikipedia.org/wiki/Double_Asteroid_Redirection_Test#Ion_thruster Ion Thrusters were invented, in paper, in 1900!!! And the first tested Ion Thruster in Space flew in 1964, BEFORE the Moon missions "Finally, however, in 1964, NASA’s Space Electric Rocket Test I (SERT I) tested this technology in space for the first time, operating its ion thruster for just over half an hour."

@@rogeriopenna9014 sir it was a bad joke

Not true. Deep space rockets can and have used them and also a model plane was created with ionic thrusters. Especially with rockets, this tech is very useful

thanks tonyw8001 and vapewoo. The vehicle works because the ionized particles emitted from the cathode bump into the uncharged air molecules on their way to the anode and create a wind. The set up would not work in a vacuum as there is no gas to ionise or push. The amount of force is agreed small but MIT have a 4m glider powered by this. Where the technology comes into its own is ironically in space where there are no particles to speak of. Space vehicles therefore need to carry their own gas to ionise such as xenon or other heavy inert gas. Proven space vehicles such as the Dawn which was launched in 2007 had 3 xenon derived ion thrusters delivering 0.09N solely from a solar array. In the vacuum of space the tiny associated acceleration moves the vehicle to incredible speeds over time. The future of Inter planetary and interstellar space seems likely to employ such technology. Doubt the thing I built here is going to change the world though :)

No, old Mavic pro. have you seen the shipwreck one?

@@woodowoods9167 No! I’ll have a look now.

@@woodowoods9167 Got it 👍. When were the sea walls breached?
