Several years ago I stumbled on a terrific demonstration titled: World Energy: Electricity, Oil, and Gas. I developed a good lesson for my precalculus class utilizing the demonstration. My school does not have school license for mathematica, but my students can of course use the CDF player. When I tried to do the lesson this year, I found that the demonstration did not work for my students, but did for me. After a lot of chatting with Tech at Mathematica, we eventually discovered that I was running a lower version of Mathematica, that the newest version of mathematica had changed some code and that thisn demonstration needed an update. The team at mathematica said they would fix it, but a few weeks later they contacted me and said it was too more work than worth their time, and it is now left at that... so I am pretty desperate here, and know there is a low probability, but I am looking for someone who might know the creator of the demo, Eugene Poberezkin? Or thinks they could take a stab at trying to fix the demo? I have the old file to share, it is attached. I am a novice coder, it would take me forever to decipher the original code, much less fix it for the newest version of Mathematica!
Thanks in advance. Matt
