Ammonia was used during World War II to power buses in Belgium, and in engine and solar energy applications prior to 1900. Liquid ammonia also fuelled the Reaction Motors XLR99 rocket engine, that powered the X-15 hypersonic research aircraft. Although not as powerful as other fuels, it left no soot in the reusable rocket engine and its density approximately matches the density of the oxidizer, liquid oxygen, which simplified the aircraft’s design.

The X-15aircraft used ammonia as one component fuel of its rocketengine

Ammonia has been proposed as a practical alternative to fossil fuel for internal combustion engines.^[49] The calorific value of ammonia is 22.5 MJ/kg (9690 BTU/lb), which is about half that of diesel. In a normal engine, in which the water vapour is not condensed, the calorific value of ammonia will be about 21% less than this figure. It can be used in…

A wave of evictions and arrests of militants from radical and housing rights movements began just a few days after the notable victory of Matteo Renzi’s Democratic Party in the European elections. The operation’s goal is clear: to evict and attack as quickly and effectively as possible during this honeymoon period between the electors and the Democratic Party (PD). Speed is of the essence as Italy will hold the Presidency of the Council of the European Union from the beginning of July and protests have already been announced for July 11 when EU ministers meet in Turin to discuss youth unemployment.

On May 28, in Bologna, the university collective CUA (linked to the Autonomous movement) was evicted from the Studentato Taksim, a building which they occupied in October. The building had been abandoned and was occupied as a protest against the high rents and the lack of publicly…

The Cosmo’s series that just ended

There can now be no doubt about it we humans are

Have you been following the Cosmo’s series that just ended?

the reason why Mother Earth is dying and doing fast.

Nothing else except our pollution is adding to the normal warming cycle of this planet? However, it is still not too late to correct this before we move across to the point of no return and it is something that I have been preaching and teaching about for over 50 years.

It is also something that will be better for our health, the planet and our pocketbooks all at the same time.

If we, the human race, will just take one of the many free alternative energies offered to us by Mother Earth and her father, the Sun, (Solar Energy), place some panels out-of-the-way, say in a desert, we could harness enough…

14 al 22 de junio 2014

Ya se vienen las jornadas! Aqui os enviamos una propuesta de programa, casi definitivo por tener actividades pendientes por quadrar. Salut!

***********

MAÑANAS

Como ya habiamos explicado, vamos a aprovechar las jornadas para darle un fuerte empujón a la renovación del tejado de casa Selba. Así, el principal curro colectivo va a ser en las diferentes faenas del tejado. De todas formas, como es probable que seamos muchas más de las que podamos trabajar óptima y seguramente en la obra, también se harán grupitos con otros trabajos. Dedicaremos las mañanas de trabajo colectivo desde el domingo 15 hasta el sábado 21.
Recordamos que iria muy bien si podeis traer herramientas para el trabajo colectivo (contacto: uri@autistici.org)
