1.5 hours runtime for like half a liter of gasoline?? That's unbelievably inefficient. A half-liter of gasoline is like 15MJ, should power a laptop drawing 30W for a week.

Maybe it would be better with a fuel cell.

    One of my friends is homeless, living out of his RV. Rather than going to the library or some other third space to charge his phone, he runs his generator. Then complains about running out of gas.

    30W is 0.04 HP. That engine is just way, way bigger than you'd use if you were designing something like this from scratch, I think. Like putting a truck engine in a go kart, and being surprised that uses a lot of gas.
