Un “drone” para vigilar playas y bosques

Acabo de ver en la prensa francesa que este verano, nuestros vecinos del norte han puesto en funcionamiento un drone que vigilará las costas de su litoral y sus bosques.Drone del ejército francés

Se trata de pequeños aviones, completamente autónomos, que viajan siguiendo una ruta preestablecida y que van retransmitiendo imágenes y telemetría. Los nuevos drones además, tienen capacidad para detectar anomalías en las imágenes que retransmiten, de ahí que sean considerados “drones” y no aviones en miniatura.

Los primeros en utilizar este tipo de drone fueron los Estados Unidos y obviamente lo hicieron con fines militares. Desde el año pasado en este mismo país, empezó a utilizarse ésta tecnología para la vigilancia y prevención de incendios forestales.

Los franceses aseguran haber desarrollado en la ENAC (Ecole Nationale de Aviation Civile) de Toulouse un pequeño drone parecido al americano que buscará bancos de medusas, restos de petróleo flotando en el mar, avisará de cualquier anomalía que detecte y como su homólogo americano, también desarrollará tareas de vigilancia forestal cuando no estén volando por las costas francesas. El ejército francés también acaba de incorporar este tipo de drone a su armada, aunque con fines menos “verdes” que el de la ENAC (lo presentaron durante los actos de celebración del 14 de julio de este año).Drone desarrollado por la ENAC

(Todo esto va a confundir aún más a los avistadores de OVNIS)

Me encanta que se desarrolle este tipo de tecnología y la encuentro súper útil, aunque me temo que esto avanza hacia los “drones paparazzi” programados para seguir con sus cámaras a quien sea, en lugar de hacia los “drone verdes ONG”.

Buscando imágenes del drone francés he encontrado esta wiki de la ENAC creada para la comunidad de desarrolladores de software y harware para drones: http://paparazzi.enac.fr/wiki/Get_Hardware ... I fear the worst, not from this community, of course, but it is inevitable that this ends up leading to people's control.

(By the way, as a curiosity and for those who are interested, these drones work with Linux [Debian] operating system).

Review of "THE HEART OF THE MATTER" Ignacio Garcia-Valino, Plaza Janes

He Heart of the Matter Ignacio Garcia-Valino, is not a book of science fiction, although part of his argument takes place in scientific circles and many of the dilemmas posed the protagonist are rooted in particle physics.The Heart of the Matter

The book tells the life of Lucas Frias, a promising specialized in quarks and subatomic particles, working at CERN and who has sacrificed everything for his career scientist. The death of his partner in a car accident that Luke used to make a parenthesis in his life and while trying to investigate the causes of the accident of your partner realize that almost did not know.

At the same time, the author places the character in various settings around the world (Geneva, Madrid, Paris, Chile, etc.) and makes him interact and discuss Science with such diverse types as psychics, mentalists, ultra skeptics, and of course, other particle physicists.

The book contains an interesting quote that the author extracts from a fable by John Godfrey Saxe and that reads as follows:

Hace mucho tiempo, en un bosque del Indostán, se reunieron cuatro ciegos que presumían de sabios, porque podían reconocerlo todo a través de las manos. Fue a visitarlos un estudiante, para aprender de su sabiduría, pero antes decidió probar si su fama era cierta. Se internaron en el follaje y el hombre les pidió que reconocieran lo que les ofrecía.
One of them said he had a snake in his hands, as he touched something elongated that was moving. The second said he was touching a stout tree with a rough bark. The third claimed that it was tied to a rope hanging from some high branch. The last one hit a firm and solid surface, and concluded that it was a wall. Everyone believed they were right.
The student warned that the four were wrong, therefore, playing only the parts, had been unable to recognize the whole. Thus one had felt a trunk; the other, a leg; the third, the tail, and the fourth, the elephant's side
.”

This fable is used by the author to illustrate the state of Particle Physics, indicating that scientists, like the sages of Hindustan, try to understand the nature of this branch of science as the elephant of the fable: fragmenting and crumbling it. In the end, as in the fable, they fail to unify the theories.

Although the author does not openly indicate this, he is making a clear allusion to the theories of the Weak Nuclear Force, the Strong Nuclear Force, the Electromagnetic Force and the Force of Gravity, which separately all make sense, but there is still no theory the only one that can explain them together.

The book is entertaining, and the scientific speculations are interesting and treated from a very rational point of view.

The only criticism is that at the plot level, the book is simple and only develops one plot line. At the character level, again it is simple, and only two characters gain dimension: the protagonist and his partner.

Still, it is a book that reads quickly and leaves a good taste in your mouth. Perhaps I would not give a 100% recommendation, but 90%.

Review of "THE CODEX OF ATLANTIS" Stel Pavlou of - The Factory

codice atlantidaFollowing my "Year Atlantis", this Christmas I read "The Codex of Atlantis" No. 1 in sales in the United States and Italy (as indicated by the editors in Spain). Just in case, the editors have published Thrillers collection rather than on Science Fiction, which is where it really should be, I guess to see if the sales figures are emulated in other countries. (I get? ... I think you go for the 5th edition).

The book is interesting and well written to be read evasion.

A nivel de teorías sobre la Atlántida es bastante original. Parte de la base de que los atlantes eran una sociedad avanzada, con conocimientos más allá de los de nuestro tiempo en campos como la nanotecnología, conductividad, estados físicos, etc. Sus construcciones eran a escala planetaria y aún quedan algunos restos de ellas. Como en las teorías de Platón, fueron destruidos por el Diluvio… aunque en el libro vemos que el Diluvio es la consecuencia de una catástrofe a nivel de Sistema Solar, que puede volver a repetirse.

According to the thesis of the book, all the monuments of antiquity are connected and are actually part of a machine on a planetary scale, capable of saving humanity or condemn it. The task of the players is to try to be the first of these premises, rather than the total annihilation of the human species.

... And they do, but just barely.

As a curiosity, commenting at one point in the book, talking about the biological timing of the banks of jellyfish, the author uses to explain the resonance and makes one of the protagonists explain how Huygens in 1660 when he was ill in bed, he noticed that the pendulums of two of its timepieces ranged at the same time when the clocks were coming. If they moved causing them to lose the pace, they came back after a while to move in coordination. If the clocks are separated, they not tuned.

This reminded me of a video demonstration of this same effect, but this time, illustrating tuning 3 metronomes.

This tuning approach is the same that governs the movements of groups of animals: groups of fireflies, flocks of birds that change direction, fish stocks, etc.

I like to find non-academic books that leverage to popularize science!

Invent a robot that hunts flies for energy and self-sufficient

Although it seems a joke, it is not. The New Scientist magazine has published in its Monday edition, this great invention. A robot that uses the sugar in the exoskeleton of the flies and allows (while flies from view) the robot does not need another power source.

If we read well the article we see that the thing is not as simple as it seems at first glance. Input power the robot obtained by breaking polysaccharide chains of the exoskeleton of the flies is very low and only allows the robot to move 2 centimeters every 12 minutes.

On the other hand, there is the problem of making the flies come ... but that have worked out well. The robot uses a flavor, synthesized from human feces, which attracts flies into a funnel that sucks up the digestive tract. Hahahaha ... you can not deny that is well thought out.

Robotic Anecdotes aside, the investigations that led to the invention of this robot open up endless possibilities:

  • The energy of the polysaccharides can be used to supplement the solar energy to manufacture any kind of "thing" that needs to be energetically autonomous. (How about a robot that when not shine, eat potatoes, beets, ... or GM soy?).
  • Production of electricity for households may attempt be made from the feces and organic waste, home users own: which would reduce the amount of waste that cities need to collect, process and eliminate. The most abundant polysaccharide in nature are starch and cellulose ... our wastes are filled with them. 50 gr. sugar can remain alight 40w bulb for 8 hours.
  • The use of sugar batteries to replace batteries in mobile phones and other devices that need to be recharged by plugging into the mains.
  • How about a water filter potabilice waste and generate electricity? Ideal for a spacecraft or orbital station. In general, ideal for any closed ecosystem.
