Fusor Forums

1 cm will most likely be an arc risk. You're going to need over a liter of barium titanate. I've never heard of anyone using it for a homemade cap, mostly people use plastic or oil dielectrics.

My final word..........Good luck in your quest and all its very uphill battles.

I have to agree there, I think the best that could come from this plan so far is a spectacular explosion of fire and sparks. If you're lucky, you'll be able to laugh with your friends about it later on.

Here's a thought for you. Make a thermite chamber and pass LH2 over the chamber mixed with your ram air (or some other fuel). Get it super hot and contain it and you have a ram air engine much like the project pluto engine without the nuclear reaction (chemical instead). If you could sustain enough thermite reaction at a temperature you could contain it. That might get you in the right weight range. Carrying HV supply and Capacitors is pretty much a no flight situation.

Of course take out a nice BIG insurance policy first!

A scram-jet is hypersonic that means super light weight and tiny for the most part. Very high altitude and you need one heck of a boost to get to start engine speed! You have to be going Mach 5 or better to even get it to hold a flame. A Ram-Jet has subsonic flow in the combustion chamber a scram-jet has supersonic flow in the combustion chamber big difference.

I didn't suck up some of the details in this post but I have a huge energy discharge cap for sale if you're interested. Its taking up too much space in the garage and needs to go soon. Don't recall specs, but its big. You can contact me offline or maybe I should put a post up in the trading post. I have lots of random stuff sitting around that could be useful to others.

Hi Andrew Robinson
If you could find out the specs or a picture, I might be interested(for another project not related to this). About other stuff I'm not ready to build a fusor anytime soon, unless inspiration strikes with a new idea.

Hi Monroe Lee King Jr
I haven't run over the numbers for the design(air intake, temp,thrust,etc),but mixing a fusor with chemical means might make a new area to look down, rather than one or the other.

PS. your rocket website, do you accept registrations?

I will post up in the "Trading Post" here soon.
