Firstly as we can see your from the UK so please go back and re-edit you post into english so english speaking people can read it, and as far as running a motor using liquid nitrogen which is basically a freezing liquid used to shrink parts is unheard of. Sorry to be so blunt but your post isn't only hard to read but it doesn't make sense. |

well im sorry if my spelling is not up to your standard and as for the car well read this that was in the eureka magazine in 2002, http://www.shelleys.demon.co.uk/fdec02ni.htm you can also try searching about it before making comments about something you know nothing about. the only thing you are right about is that it freeze's things liquid nitrogen has a temp of -200 that means at room temp it will boil and expand by 200-300% atleast so makes it perfect to run an engine that if you no how witch you definetly dont. all i want is abit of help and if been up alnight trying to get it thats proberly why my writing isnt that good |

Hi jdearman The PicLog isn't meant for that sort of application, though it could be made to work. I have a suggestion. First up, it would be hard to get someone to write a VB program for you, writting a logger program would take some time. If you can get hold of VB6 ( Visual Basic 6 ), you could use the PicLog program as an example and then over time write your own program, or modify the PicLog program to do what you want. You could even write the program in the older version of Basic, QB 4.1 or 4.5, which came free with DOS. Sound like a interresting project your dad is working on, though I dont know how he is using nitrogen. At a guess he could be using it as a source of safe compressed gas, and using a gas pressure engine ( like a steam engine ) to drive the vehicle. Nitrogen would certainly be environment friendly, as most of the air we breath is nitrogen. We use a lot of Nitrogen at work for laser cutting, cheap and keeps the cut cool.

OK Jdearman, Ive done some research and the link to another forum where I posted a link to your claims is here http://www.electro-tech-online.com/showthread.php?p=170738#p ost170738 Now get your Dad to look at this and tell us why so many universities have dropped the proposal. By no means do I mean to dis-credit you but if your onto a good thing share with the RE world as like me like other people around the world are calling this a crank. |
