Re: origonal ???

the first sujsted chainge i am puting forword for people to concider is to make the combustion chamber; circular, spherical, or toroidal. and to have the intake and the exaust enter it tangetialy, such that they make air in the chamber spin around. this should alow the air to continue to enter the c...

Re: origonal ???

i thought sonic choking was one of the problems to be dealt with?
the fact that the gas coming down the exaust gets to the speed of sound then can not go any faster, dispite having the enregy avialabel to do so if the phisics alowed!

My idea is to build a thermojet and use a modified blow torch to fuel it. I have modified a servo for 4x 360 degree turns to enable me to open the valve for thro...

fusion well of topic

An outline for a working fusion reactor. A catalysed D + D = He4 using the following steps. I.Pb207 + D = Bi209. II.Bi209 + D = Po211. III.Po211 + D = At213 OR Po211 = Pb207 + a. IV.At213 = Bi209 + a. the first two steps being achieved by sonoluminescents fusion in liquid alloy. Now in English for p...
