Hi Dmtry,
"The efficiency of railguns is lower then 10% ... it's around 7% .So at this moment i have around 30% of efficiency .. 100J on electrical energy is transformed to 30J of kinetical energy."
Here is an abstract of an old article mentioning 47% efficiency for railgun launchers:
https://ieeexplore.ieee.org/document/364679 https://ieeexplore.ieee.org/document/364679 Abstract: Railgun launchers must be energy efficient to realize use in practical systems, especially mobile applications which require compact power supplies. This paper shows that railgun launcher efficiency has already been demonstrated at 47 percent at launch kinetic energies up to 8 MJ. Improvements in armature performance have made this performance level possible. Foreseeable improvements in armatures and power supply-launcher integration will push launcher efficiencies to at least 66 percent.<>

Hi. So it's not Rail GUN, but it's better. It's coilgun .. you can call it so
Better in that way .. that effciency of my system is more then 30% .. and can be increased to the 90% and more! And second is that my technic permit me to decrease volume and mass of the device to very low level. That is very important!

The work is in the progress.
If you look carefuly to the efficiency of top level electromagnetic guns - you'll see that their level of efficiency is below 10%. Mine one is more better than any known technic for this moment
Hi Warren!
Im good.
Yes i work with HV .. of cours .. but im using special fast capacitor discharge technic .. and playng with KiloAmps .. it's very complicated.
I made and tested first level prototype .. carefule tested it .. and take all the data.
Now i work on next generation protoype .. level two.
And im looking for help ... to doing business with this device.
If someone is interested in that .. im ready to cenversation .. and to share some more data about my work.
For the moment my technology allows me to do next thing's:
1) To made a real portable EM GUN .. with mass and power parameters at the same level as fireguns
2) To made an Aerospace mass launcher .. for delivering payloads to space orbit directly from earth.
That's it.
