I know it can be done because a friend of mine made one powered by a weed-eater, I just don't remember exactly how he cobbled it all together now. He and a group of coworkers were big into attending Jimmy Buffett concerts at the time. They made a portable "Tikki Bar" they'd set-up and along with the weed-eater powered blender was quite the attention getter. I've seen it demonstrated and it works but as one would expected it's noisy and a bit on the smoky side.
