Canon électromagnétique à supercondensateur : 350 km de portée ! Canon electromagnetique bae systems Comme pas mal de technologies de pointe, le supercondensateur peut servir à bon escient (par exemple comme batterie à recharge ultra-rapide pour la voiture électrique), mais aussi pour fabriquer de puissantes armes de guerre. Ainsi, le canon électromagnétique utilisant des supercondensateurs devrait bientôt devenir une arme tactique pour la marine. General Atomics, une entreprise de défense et de physique nucléaire basée à San Diego en Californie et BAE Systems, une entreprise britannique travaillant dans les secteurs de la défense et de l'aérospatiale, planchent sur un canon électromagnétique surpuissant qui intéresse déjà fortement l'U.S. Navy. Le canon électromagnétique n'est pas un canon ordinaire, car il n'utilise pas de poudre ni produits chimiques. Il fonctionne en envoyant un courant électrique pulsé très intense le long de deux rails parallèles entre lesquels on a disposé un objet métallique.

Ma ville demain - Architecture. Future Shock Levels. Paul Hughes September 27, 2011 The first person to introduce the concept of Future Shock was Alvin Toffler in his 1970 book, Future Shock. The main argument is that society is undergoing an enormous structural change, a revolution from an industrial society to a "super-industrial society". This change will overwhelm people, the accelerated rate of technological and social change will leave them disconnected, suffering from "shattering stress and disorientation" - future shocked.
A few years earlier, Gordon Moore in his now famous paper (PDF) introduced the idea that would eventually be called Moore’s Law, that states that the speed and density of microprocessor design will follow an exponential curve. As one of the leading thinkers on the singularity, Eliezer Yudkowsky is someone accustomed to thinking about extremes of future technological change and advancement. Shock Level 0 Degree of Change: Flat. Technologies: Same as today, maybe more TV channels, bigger cars or TV's. Shock Level 1. Cette merde doit cesser FRESCO. Ideolog. Complexité. SoonSoonSoon - Prenez un temps d'avance. Why Green Infrastructure Makes Cities Awesome. The American Society of Landscape Architects has just released a massive database of 479 case studies describing the successful application of ”green infrastructure” techniques that collect and process rainwater naturally before it flows into receiving waterways as polluted runoff.
The database demonstrates the power of increasingly widespread application of sustainable practices to prevent pollution while simultaneously bringing nature and natural process back into urban environments. The case studies come from 43 states, the District of Columbia, and Canada. This promises to be a great resource: One of the most pressing environmental challenges facing cities and suburbs in the US is the impact of polluted stormwater runoff from developed land – highways, parking lots, rooftops and other impermeable surfaces – into our rivers, lakes, and coastal waters. The problem becomes particularly acute in cities that drain both stormwater and sewage into a common set of pipes and conveyances.
