It is infinite if we assume that human and animal waste is infinite. As long as you have shit, you'll have methane and hydrogen sulfide. Both flammable and combustible.
Sulfides are usually taken out before the burning process, they are flammable but sulfur is also highly corrosive.
Second, human and animal shit is not infinite, it would be infinite if you would have infinite humans and infinite food to feed them all, and we don't have the second one for the current population. Besides that, when people usually refer to cattle waste they compare it to release from human activity forgetting that in whose cases it's a small percentage that is being released while a huge chunk is used, all the 1 billion cattle in the world, even if they would release pure methane into the atmosphere which is not the case wouldn't make a dent in Russia's market share let alone worldwide.
Once you make dam on a river it can keep working with minimum maintenance for 100 years or more.
Yeah, the problem is that dam also would need an infinite resource, which is not water, it's places to put them and the one reason why Netherlands produces only 0.1% of it's total energy from dams, and the reason why 4 countries in the world produce 50% of the global hydropower.
No, bottom line! electric energy is not an infinite resource and will never be free, just as tap water isn't!
With the current spike in
BTC price it will be pretty interesting to look at the mining consumption, bitcoin price doubles, so does the amount miners get.
When it goes 10x....things will go interesting, we won't be talking about Switzerland but Germany.
