What is the best way to deal with a pond lined with soil taken from dry ground, which emits methane bubbles nonstop when underwater? I'm concerned it's hurting life in the water.

Maybe, maybe not. It isn't like most folks can live off of a garden plot of a normal house, if you even have a garden plot. I cannot cycle 20km fairly leisurely in an hour: I live in a mountainous area, but lived most of my life on flat ground and going uphill is freaking difficult, even if I'm going at a leisurely speed - and sometimes, downhill is brakes all the way down. And I don't know how much this person drive…
Fair enough, but my main point was that cycling or walking 20km probably consumes less energy than the “hard work” of harvesting methane for 8 hours.

it probably speeds things up rather than killing them, and you know on the scale of BP pouring millions of oil into the ocean, I reckon what this guy is doing is absoloutley fine and the environmental damage is well within range of what the local environment can cope with and recover from within a reasonably small time frame.
It's "probably" ok? Based on what?
> 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?
This made me chuckle. I am guessing he is trying to show how ridiculous our life style is without fossil fuels?

> 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.

You can probably do that, but don't delude yourself that you're doing anything for the environment. Methane itself is a very potent greenhouse gas. Everything you do with methane is only environmentally friendly if you have a very low leakage rate. Whatever homegrown DIY biogas facility you're creating very likely does not do that.
If you're collecting something that would be produced anyway, it's going to be a net bonus.
Of course whether that happens depends a lot on where you're living.
True, and highly disruptive of orthodox economic theory which posits the primacy of convenience.
Searching for the terms "secu" and "safe" doesn't yield any results. I know this is more of an art project, but in a photo he's driving through a city. What are the security implications of this? Also searching for "poly" doesn't yield any results, so I'm left to hope that the is using polycarbonate to provide some kind of safety shielding in case things go south.

I don't understand what the security implications might be? It's just the normal gas that's available from mains gas everywhere, in a low-pressure tank. Probably no more dangerous than existing CNG/LPG vehicles.
