Given that this involves disturbing the bottom of the pond, and that burning methane still produces CO2, this may actually be less environmentally friendly than just using gas.

> I cannot cycle 20km fairly leisurely in an hour: I live in a mountainous area Not a good counter argument. In this case, the moped will also use more fuel.
Sure, it isn't the best, but I know lots of other folks cannot either, and reasons vary. The point really is that cycling 20km isn't realistic for a wide swath of population. And sure, it might use more fuel... when you go uphill. Downhill, you might not even need the power.
Same as with a bike.
> Eight hours of hoeing in a ditch supplies him with enough fuel to ride his vehicle for 20 km Hmm, this is an art project but you can cycle 20km fairly leisurely in an hour. 8 hours of toiling in the ditches probably might be better used growing vegetables so your food isn’t being driven in?
OF COURSE there's more efficient ways to get around, this isn't an attack on anyone's intellect or common sense and there's no need to react to getting nerdsniped by going "well ackchyually" and reinventing combustion engines and fuel from first principles.
It's fine to just go "that's cool" and move on with your life. The guy that made this knows it's not the most efficient use of his time.

What was invented?
Also, on a side note this sort of "environmental solution" reminds me of the 1970's beached whale disposal in Oregon.

This made me chuckle. I am guessing he is trying to show how ridiculous our life style is without fossil fuels?
Please note that this is an art project and not a serious invention.
Agreed, the term "inventor" in the headline makes it seem unnecessarily naive. But even if it's art, I suspect that some objective benchmark comparison fits very well: assuming that you had serfs to do the dirty work for you, at eight man-hours for 20 km this would be clearly more efficient than having them carry you around in a sedan. And only slightly less efficient than a rickshaw. Great way to put our fossil ever…

Well... if it gets a few people to learn more about this topic then that's serious enough for me. Many have very strong opinions about energy and fossil fuels, but few really understand what they're talking about. For example they don't understand that natural gas is actually a very potent greenhouse gas and he's doing the world a favor by burning it. On a larger scale, we could certainly do more to stop methane from…
Next step, tank it directly from the cow.
That said, if I were to over-engineer this, they could make barns with a closed air system that filters out any methane produced.

Probably motor oil, these mopeds normally run on a fuel/oil mixture.
But has he prooved there is only lubrication oil in there, oil also burns, maybe the methane bubble is just for show and he has actually converted the engine to some sort of diesel/ethanol/any other oil engine! ;D
I want to se the engine stop when the ballon is empty! :\
Also now I watched the video: he spends more energy collecting the gas than it would have taken him to use a regular bike. But fun idea.
