Bobjengr, it has seemed to me for quite a while that a system for intentionally producing methane from both municiple waste and also sewerage would be quite useful. Not only producing fuel but also reducing the nastiness of our waste stream. And it is not clear as to why nobody else is looking into it, except that there is probably a lot more funding available for those other types of projects. Gas from trash does sound quite unexciting, after all.
I am with you in regads to the fact that the world will likely end due to some other freak type thing as opposed to global warming. I do think it will be interesting to see all of the ways in which we produce/develop/utillize different fuels between now and then.
You are certainly correct with this one. I had a consulting job last year in which we investigated the entrapment of methane from landfill sites. The economies were a bit tough but the technology is in place today. Also, we have a remarkable abundance of natural gas in its raw form. I think as gasoline prices escalate, we will see natural gas automobiles increase in number.
Pubudo. Yes, but. . . Gas may be a slource of carbon, but it's a lesser from than oil. So there is progress in moving to gas. Electric vehicles come with the same problem, since most electricity is generated by buring coal or gas.
Jmiller, the fact is that there is a whole lot of natural gas available easily, and a lot more with some more work. So there would easily be enough for a long time. And before that "long time" ends we will probably have some wonderful new source of energy available.
My own feeling is that long before any natural calamity does any real damage, some "nut-job" fanatic from some heathen religion will do serious damage to the entire ecosystem and those remaining will suffer horribly. Read the newspapers and you will understand who I am talking about.
Pubudu, Burning anything produces carbon emissions, which carbon dioxide was never considered a problem until those intent on destroying our way of life got hold of this global warming panic. If you want to give up all of the benefits of an energy consuming society and go back to living in a horribly primitive manner, that is fine, BUT do NOT expect that everybody else will choose to suffer for your beliefs. Even if things do change, there is no adequate and accurate proof that things will be worse than they are.
We have more knowledge about how to adapt to any changes now than has ever been available previously, so if we can't figure out how to live as things change, when the change is this slow, we are to be pitied. And what about all of those who are constantly telling us that all change is good? Or do they only mean that the changes that they do to us are good? What about those individuals?
I think the cost is always a concern when it comes to alternative fuels. The fact is, in America gas is pretty cheap compared to other parts of the world. Therefore, it's tougher to come up with incentive for people to switch. Money is a big factor and if it's going to cost more and it's not cheaper in the long run, people won't just switch on their own.
I have heard of this technology as well, using the methane off of farmyard waste to generate electricity. Let's face it, we have lots of animal poo, and it's going to stink, so you might as well burn it and generate something.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
