Firstly i need to emphasise this engine idea is part 2 of
another idea i have yet to write. look for HTE post will
publish shortly. there is a reason for doing it in this order.
Basically the engine consists of a plastic cylinder
containing an aluminium ring, in the centre of the tube is
a
conductive tungsten/copper needle that can move up and
down length ways. using the same principal that a van der
graaf generator uses the aluminium ring builds up static
charge and eventually produces an electrical arc between
the needle and the aluminium ring. the position of the
needle determines the charge needed to arc the gap and
hence the amount of energy that can be displaced.
the basic idea is that if there are enough electrical arcs
the air surrounding them will be plasmarized. if the plasma
is encouraged to flow a certain direction the air pressure
one side of the cylinder relatively high (intake side)
compared to compared to very hot low pressure gases
being exhausted on the other side thus creating thrust like
a normal jet engine.
what do you think?

I'm not sure your oscillating needle idea constitutes a generator. [sninctown, Jul 26 2009]

I think I'd like to know what the power source is.
I also think I like capital letters. |
|
| |
It's a ramjet (well known technology) using an
electrical discharge in place of a fuel. |
|
| |
The aluminium ring will erode very quickly at high
current flows in the presence of an active arc and
hot air. |
|
| |
[AWOL] is correct in asking about the energy source. |
|
| |
firstly capital letters are largely redundant. in
English the full stop usually indicates the end of a
sentence, and in this scenario why is it necessary
to indicate the beginning of the next sentence
using a capital letter? one can assume that the
words following a period are a sentence and the
first letter of that sentence is the beginning of
that sentence...we do not need punctuation and
capital letters to indicate the end and the
beginning of subsequent sentences. capital letters
have a place in proper nouns, abbreviations,
anagrams etc. |
|
| |
the power source of this device is from the first
part of the invention, yet to be published. namely
a device called an HTE. |
|
| |
i am sure replacing the aluminium ring and needle
in an engine periodically can be equated to
replacing the oil filter, spark plugs, fan belts etc of
a conventional engine. this does not concern me
greatly. |
|
| |
Vowels are largely redundant, also. Not using them would be stupid. |
|
| |
Using an arc to heat air is extremely inefficient. (Notice all the arc-based room heaters on the market? Right.)The heat energy is almost entirely transferred into the contacts at each end of the arc. Arc welding is much more efficient than oxy-acetylene welding for that exact reason. Piezo-spark lighters, oddly enough, are also effective for the same reason: the heat doesn't transfer out to the air well, and allows a small amount of air to be heated to incredible temperatures. |
|
| |
//vowels// YHWH to that [lurch]. I don't recognise your argument against capital letters [codrakon] - paragraphs too are "largely redundant" in those terms, but like capital letters, they provide a visual aid that helps make reading a block of text that much easier on the eye. |
|
| |
perhaps if the arc travelled a shorter distance and
heated a thicker needle (hollow) this idea might
be efficient enough to work. if the distance
between the ring and needle is small enough the
relative surface area of the needle to heat a
smaller volume of air might make it feasible. "The
heat energy is almost entirely transferred into the
contacts at each end of the arc" could be the key
to heating enough air, fast enough and efficiently
enough - just increase the surface area of the
contacts. |
|
| |
next the reason why the no capitals argument is
unfamiliar is because it is my own argument. i
think it is pretty sound. as for paragraphs and
vowels these are necessary for obvious reasons.
actually from my point of view the dropping of
capitals from the beginning of the sentence
actually advances the english language because it
is now possible to disinguish a sentence that
starts with a proper noun of the same spelling as
another word. |

bad example but you get the point. |
|

electrical discharge jets *are* plasma, just not at the concentration hinted at in the post. And what's this crap about capital letters ? |
|
| |
I'm still waiting for the power source that is light enough to produce lift thrust in the form of electricity. waiting, waiting.... waiting..... |

Electric-arc Aluminium welding is performed using
TIG, a Tungsten electrode and an Argon (or
Argon/Helium mix) shield gas; and there is still a
significant erosion rate on the tungsten electrode.
The Aluminium parent material liquifies, and were
it not for the inert gas shield would rapidly oxidise
and/or ignite. |

We predict that the service life of your propulsion
system, will be brief, but highly exothermic (and
impressive). |

hey at least this engine would be fun to play with.
perhaps one can use it for rockets (instead of carrying fuel on board for the initial lift off - just
blast it with some high voltage). weapons also come
to mind. |

The arguments against correct punctuation are suggestive of an attempt at trolling. Do you want your idea for a new type of engine discussed, or your "reasons" behind the poor grammar [codrakon]? If you keep this up, eventually that which you post will simply be ignored, or boned without comment. Do you want that? |
|
| |
If you want to front an idea for "no capital letters at the start of any sentence", you may want to consider posting that up as a totally separate notion. |
|
| |
Point taken. Will copy and paste my stuff into Word
before I do it again. Actually my typing is very poor
and I am too lazy to hit the shift key. |
|
| |
A better ramjet power source would be the electrical charges in halfbakers' overactive brains. |
