I could see how pd might do that. I'm on hemodialysis so I wonder if it would cause belching at all.
I fart the whole time I am on dialysis. I used to try and hold it in but i would get a stomach ache and basically blow up the elevator when i left. As soon as i stand up after dialysis i do a few good belches and then i feel okay. Of course, then there are the sulfur burps but they are a different story. Basically,with dialysis, i am sure i could power a small village with natural gas.
Now if you could bottle it all up and use is an alternative fuel source, you would be rich$$$$$$$ it would be less than $3 per gallon.
