This is partly correct, in that about 70% of methane collected from landfills is converted into electrical power on-site, with huge Caterpillar Internal Combustion engines coupled to a generator, a so-called genset, and sold into the local grid. The other 30% is where the landfill is close enough to a natural gas pipeline that a connector trunk line can be put in place and in this case the methane has to be upgraded a lot more to meet quality specs so the pipeline folks will accept it. Also known as Biogas, methane from landfills is considered a Renewable/Green Energy and there's federal funding and/or tax breaks propping up this small but vibrant sector of the energy industry. In particular the pipeline projects, generally called Hi-BTU Landfill Gas, are putting a lot of the bread on my table because most pipelines won't accept it with more than a few parts per million of Oxygen (O2) and my company is the main supplier of O2 removal technology/catalyst to this niche industry. We have 15 or 16 landfills using our catalyst right now, and several more projects on the drawing board.That's kinda what they are doing with landfills now. They cover them, at different stages with a gas barrier, and control output of the gas produced from decay. The gas is used for power generation.

Interesting. A few years ago I consulted at a landfill in the Los Angeles area that had 7 big gensets, each in its own building about twice the size of a double-wide. The noise inside those engine houses was deafening. Of course, being California, they were under a microscope on meeting emissions regulations on the engine exhaust side and had a small fortune tied up in catalysts for NOx abatement and VOC abatement (volatile organic compounds i.e. methane) on the back end.Off topic but to give you an idea of just how intertwined fossils fuels are with everything in our lives ... we took 11 of those Cat Gensets to San Antonio from Peoria to the new Microsoft “ complex “ as back up generators for their servers in case the grid goes down .
Nice insight.

I've seen more burn stacks that I have methane recovery.This is partly correct, in that about 70% of methane collected from landfills is converted into electrical power on-site, with huge Caterpillar Internal Combustion engines coupled to a generator, a so-called genset, and sold into the local grid.

Each one of those 3500 cat gensets are 1million a piece . There are only 3 facilities in the country that make them . That I’m aware of . Peroria , Kansas and Chattanooga ( use to be two plants there until one closed 2 years ago . ) California sux trying to haul anything into it . Most of our orders come from the Kansas facility . The biggest one will go between 19’-22’ wide , normal around 17’6 tall and about 77’ long . Lots of permits lol
Landfills are required to collect the gas, and burn it in a flare stack if they are not recovering any value from it.I've seen more burn stacks that I have methane recovery.
There is one in Arkansas that sells it to their next door neighbor. They use it to melt steel to be refurbished.Landfills are required to collect the gas, and burn it in a flare stack if they are not recovering any value from it.
The logic there, is because methane is more harmful as a greenhouse gas than the CO2 created by burning it.
So, yes, most of the landfills are still just flaring the gas.
Interesting. About 5 years ago I consulted on one in New Hampshire where they were selling the raw gas to a nearby paper mill for boiler fuel, after only removing some of the H2S (there can be a LOT of H2S) and moisture. There was litigation involved because the gas processing facility had a lot of unexpected corrosion from a poorly designed processing scheme. Although I was hired to help the potential defendant stave off a lawsuit, I could only conclude that they were at fault.There is one in Arkansas that sells it to their next door neighbor.

It caused a bit of a stink though. The local natural gas company tried to block the deal. No dice for them.
They could at least cook the rats for the homeless with that fire.Landfills are required to collect the gas, and burn it in a flare stack if they are not recovering any value from it.

H2S is some very nasty ****. One breath and you’re dead....Interesting.

I have legitimately never heard of a wide use of steam in Rome. do you have a link? I know there were a guys who created some very basic things, but hadn't heard of it possibly going beyond that.Re: fossil fuels
The industrial revolution was poised to happen in the middle Roman empire, but the reliance on slave labor and fear of how the change to steam power would affect the balance of influence put the kibosh on it.
I see much of the same mentality today. I respect what fossil fuels have done for our country and for civilization as a whole but I believe it is time to explore renewables on a larger scale. It will be the monetization possibilities that ultimately win people over, and once it is more profitable that fossil fuels I believe we'll see the shift happen at increasing speed.
We are stubborn as a species. With some things it's very beneficial; with others, not so much.
Because building construction is so green. What do they think happens to all of the demolished materials? Are they going to construct these new buildings without the use of gas/diesel cranes, eartmovers, etc? Will the materials get hauled to the site using electric powered tractors?Knock down and replace every single building in America and build it back so that it's green efficient.
I actually can't believe they released that.
I've read quite a large amount on the Roman Empire/Republic and I have to say this is the first I've ever heard of steam power being a consideration.Re: fossil fuels

Damn ...that’s almost too harsh to wish on anybody .
