Motor híbrido de combustión y vapor
Publicado @ 15 June 2007 por Oscar
¿No sería fabuloso depender menos de combustibles a base de petroleo que son altamente contaminantes?
Encontré un post acerca de una implementación de un motor híbrido con un enfoque diferente: combustión y vapor, aún cuando parece un enfoque interesante y del que se podría sacar mucho provecho ya que se podría usar agua no apta para el consumo humano, otros sistemas híbridos ya llevan una gran delantera como los realizados en base a combustión/electricidad. A continuación el artículo (copio y pego):

Motor híbrido de combustión y vaporMotor híbrido gasolina y vapor
Funcionamiento del motor híbrido gasolina/vapor de EcoGeek.
El concepto de motor híbrido gasolina/vapor difiere bastante de las combinaciones híbridas habituales que suelen ser gasolina/eléctrico, aunque lo bueno es que sería aplicable también a éstos. Suena bastante retro por aquello del vapor y personalmente le vería más futuro aplicado a gran escala si se hubiese comenzado a desarrollar mucho antes, pero me parece brillante y digno de mención en cualquier caso.
En un motor de gasolina normal (incluyendo el que llevan los coches híbridos gasolina/eléctricos) se quema una mezcla de aire y combustible. Al prenderse la mezcla (por acción de la bujía en los motores de gasolina o espontáneamente en los motores diésel) la expansión de los gases producidos impulsa el pistón a lo largo del cilindro para mover el cigüeñal.
En el motor híbrido gasolina/vapor el funcionamiento básico es el mismo descrito, aunque con una curiosa variación: en una primera carrera el pistón es impulsado por los gases en expansión originados de la combustión del combustible. Esta ignición calienta la temperatura de la cámara de combusión hasta los 800 grados centígrados, momento en el que se inyecta agua a presión en la cámara de combustión: el agua se vaporiza al instante incrementando su volumen unas 1.600 veces y empujando de nuevo el pistón, elemento que vuelve a realizar su carrera por el cilindro sin haber quemado una gota de combustible. Para el siguiente ciclo (en tanto el agua ha enfriado la temperatura del cilindro) volverá a inyectarse combustible y así sucesivamente.

Spanish company touts process to turn urban waste into biodiesel
By Ron Kotrba
A group of Spanish developers working under the company name Ecofasa, headed by chief executive officer and inventor Francisco Angulo, has developed a biochemical process to turn urban solid waste into a fatty acid biodiesel feedstock. “It took more than 10 years working on the idea of producing biodiesel from domestic waste using a biological method,” Angulo told Biodiesel Magazine. “My first patent dates back to 2005. It was first published in 2007 in Soto de la Vega, Spain, thanks to the council and its representative Antonio Nevado.”
Using microbes to convert organic material into energy isn’t a new concept to the renewable energy industries, and the same can be said for the anaerobic digestion of organic waste by microbes, which turns waste into biogas consisting mostly of methane. However, using bacteria to convert urban waste to fatty acids, which can then be used as a feedstock for biodiesel production, is a new twist. The Spanish company calls this process and the resulting fuel Ecofa. “It is based on metabolism’s natural principle by means of which all living organisms, including bacteria, produce fatty acids,” Angula said. “[It] comes from the carbon of any organic waste.”
He defined urban waste as “organic wastes from home like food, paper, wood and dung,” and added that any carbon-based material can be used for biodiesel production under the Ecofa process. “For many years, I wondered why there are pools of oil in some mountains,” he said, explaining the reasoning behind his invention. “After delving into the issue, I realized that [those oil deposits] were produced by decomposing organic living microorganisms.” This, in Angulo’s mind, sparked the idea that food waste and bacteria could be turned into fatty acids that could react into biodiesel. Two types of bacteria are under further development by Biotit Scientific Biotechnology Laboratory in Seville, Spain: E. coli and Firmicutes. The Ecofa process also produces methane gas, and inconvertible solids that can be used as a soil amendment or fertilizer. “There is a huge variety of bacteria,” Angulo said. “Currently, [biodiesel producers] receive a fat that must be processed through transesterification into biodiesel, but we are also working on other types of bacteria that are capable of producing fatty acids with the same characteristics as biodiesel.” He said this would eventually allow producers to skip the transesterification step.
Ecofasa may avoid the ongoing food-versus-fuel debate and its expected successor, indirect land use, with its Ecofa process. “It would not be necessary to use specific fields of maize, wheat, barley, beets, etc., which would remain for human consumption without creating distortions or famines with unforeseeable consequences,” the company stated in a press release. “This microbial technique can be extended to other organic debris, plants or animals, such as those contained in urban sewage. You can even experiment with other carbon sources, and this opens up a lot of possibilities. It is only necessary to find the appropriate bacteria.”
The company created its name by combining the term “eco-combustible” with F.A., the initials of the inventor.
“Today we feel that we can produce between one and two liters [of biodiesel] per 10 kilograms of trash,” Angulo said. That’s a little more than one-fourth to one-half of a gallon for every 22 pounds of trash—or between 24 and 48 gallons per ton of urban waste. “We are working to improve that,” he said.
