There are two options. First, run your MBP off of the battery, then when the battery dies, close the lid and recharge the battery in sleep mode, as this will draw much less power than running the machine and charging the battery.
Also, and this is a little dangerous to your work, remove the battery and run solely on the in-seat power. With the battery removed, no power will flow to the battery and you'll be able to run at on the 75 watt power from the seat. But ... be careful, save often, and I'm not responsible for the consequences. Consider if the guy next to you bumps the plug and it falls out -- your machine will go off!
I am not an electrical engineer, but these options worked for me. I would appreciate feedback from any EE types on how bad of an idea this is...
