¿Cómo capturar las emisiones bovinas y transformarlas en biogas?

Investigadores del INTA desarrollaron una técnica para recolectar los gases que emiten las vacas y convertirlos en biogas comprimido apto para ser usado en el hogar. Hacia el año 2050, se prevé que disminuyan las reservas petroleras y aumente la necesidad de dar con fuentes de energía alternativas y renovables. Ante ese panorama, el uso de gas natural comprimido podría suplirse con este logro. La energía obtenida de las vacas serviría para que, en aquellos lugares donde no llega la convencional, los productores tengan una alternativa para cocinar, iluminar sus viviendas e, incluso, manejar sus autos. De acuerdo con los especialistas, el biometano purificado y comprimido puede ser utilizado para generar energía calórica, lumínica y motriz. Una vaca emite alrededor de 300 litros de metano por día, que pueden ser utilizados para poner en funcionamiento una heladera de 100 litros de capacidad a una temperatura entre dos y seis grados durante un día completo. Para los investigadores,

Five Essentials Of Successful Ranches

Strategic Planning: Hollistic And Integrative Nearly 20 years ago, I was asked to give a talk to several groups about “10 ideas or practices from which our ranch has benefited the most in the last five years.” I made the list of 10 and gave the talks, which seemed to be well received. Since then I have reviewed the talk on several occasions. I soon consolidated the list to five and remain satisfied that they are essential to good success and, when thought of broadly, cover everything a manager needs to consider to have excellent results. Five essentials A lifelong approach to management needs to be both integrative and holistic. We must strive for continuous improvement of the key resources. On most ranches these will be land, livestock, and people; but could expand to include wildlife or other resources. We must assemble and use good analysis and decision-making tools. We must wage war on cost. We must place an emphasis on marketing. Over time in this column, I wil

An odd thought about ethanol

At least in one aspect, the renewable fuel should have quelled the debunkers. The cars and pickups you drive are running longer than ever. Recently I was having dinner with a few farmers and we got to talking about ethanol - they are members of their state's commodity groups and they support ethanol. And I was sharing how whenever I write about ethanol, I will get a note or comment from someone who hates the fuel. It doesn't happen every time (and ethanol haters are welcome to comment below) but it does happen. After all these years of burning E10 (or higher) in our gasoline, I still have people claiming the fuel is a disaster for cars and longevity, etc. And for very old cars that could very well be true, but it sure isn't for newer cars. I'll share an interesting fact. During the Detroit Auto Show - or the North American International Auto Show - on a radio interview one executive noted that while car sales are rising again, well past the slump of 2008, there
