Shockwave annihilation near an air intake, in hypersonic flight. A secret known to the Russians and jealously guarded by the Americans for twenty years. Their aircraft (the spy plane Aurora and their hypersonic antipodal bomber) have been flying since 1990 for the first and 1997 for the second. The secret lies in placing a wall-mounted MHD generator just upstream of the air intake, which acts as an MHD decelerator and slows down incoming air from 10,000 km/h to subsonic speeds before it enters a conventional turbojet. Nov 2003. Dossier
ANTIBABEL (created in 1988): Is it possible to design a software that allows people speaking a large number of languages to communicate with one another? Automatic translation software has its limits. It relies on a limited number of languages. The solution lies in designing documents in their common form: their semantic structure. Antibabel is a software project with semantic message input. The machine refuses "anything it does not understand the meaning of," thereby eliminating all ambiguities, gallicisms, anglicisms, etc. On request, the software then produces the sentence or text in a chosen language. It may not be literary elegance, but anyone wishing to disseminate their message to a broad global audience will be able to do so. Antibabel.

Lasers: MTHEL or Mobile Tactical High Energy Laser (May 2004). The Americans and Israelis have successfully tested the first mobile high-power laser battery capable of intercepting a Katyusha rocket or shell, singly or in salvo, at relatively short range. These lasers, developed by Northrop Grumman since 1961, complement the ABL (Airborne Laser), or airborne lasers mounted on a militarized version of the 747. For a territory like Israel, this represents an extension of Patriot anti-missile systems. These lasers generate several megawatts, implying a target illumination time of about one second. The video footage from these tests is particularly spectacular:
