31. Biogas: How cow manure and French fries run a power plant on the farm

Electricity, heat, animal bedding and fertilizer and you're mitigating the effects of dumping raw manure on your fields? It was a tantalizing package for dairy farmer James Callaghan and it was why he he set up a 500 kilowatt biogas operation on his farm. Learn how it works and other facts about biogas at www.greenenergy...

According to me a 75-kWh electrical gas plant running 24-hours a day would suffice for 250 cows. So why the extra 425 kWh? The electricity I think is considered the by-product of heat production with heat production being two times the amount of electricity produced. Regardless of the error in my calculations, this is quite amazing.

Selling it to the grid

[@jakiulhassan1668]

i am from Bangladesh..Can I get some help for Bio-gas plant? What will it cost to families, such as 100? What matters is to focus on? What kind of future can we get in trouble? How to do the maintenance? Can you give me any technical support? And I get to see your project?

Hi, did you find answers to your questions?

[@gurpreetsinghbala5663]

Great ideas

[@Vidyasagarbb]

Great. Quick question. Does electricity produced will fetch equal money to cover the cost of fodder to cows entirely ? Asking the question for a purpose. kindly let me know.

The only thing I think they could do better is capturing the carbon in order to feed it to an Vertical Tube Algae Farm. Then use the algae produced oil in order to power in another generator. And recapture the carbon as vegetable food. 0r just refeed it to another batch of Algae. I think his idea of the greenhouse is a great idea as well. But I would use the below ground Greenhouse design that they're employing in Nebraska in order to grow citrus. Citrus grown on the Canadian border and the north of America. This is truly the Golden Age through real Green Technology.

How about vermicomposting with some of the manure ?Would sure help with his greenhouse venture .

Much sooner there wasn't dairy farms to begin with. Did you see the calf away from its mother, so we can take the milk. If harm is going to be done at least the waste is being treated. Why isn't there a biogas plant at every wastewater treatment plant already?

how would your system work om pig manure,henry very interesting

[@otrogreandcorgi9818]

any type of manure in general would work. much like human would work quite well. The Asians and the hippies have been doing this for years. personally I'd like to see them recapture the carbon in the stack and feed it to an algae farm to produce bio oil. You could literally continuously refeed the same carbon back into the algae farm. at some point the original carbon would be completely consumed. But the bio fuel produced could produce even more electricity to be pumped into the grid. there's whole lines of biofuel crops that could make use of lower quality land. Look up giant grass biofuel. wood pallets for thermal power plants. carbon capture,
