DARPA Working On Arthur C. Clarke Weapon Idea

holy_calamity writes "DARPA is working on a weapon which is similar to one first described by Arthur C. Clarke in his 1955 novel Earthlight — firing jets of molten metal using strong electromagnetic fields. The Magneto Hydrodynamic Explosive Munition (MAHEM) will function on a smaller scale than Clarke's fictional blaster. DARPA's write-up says it could be 'packaged into a missile, projectile or other platform and delivered close to target for final engagement and kill.' Clarke is also widely credited with suggesting geostationary communications satellites — what other ideas of his will come to pass?"

    And this concludes another lesson in "Why the hell didn't I file for patents on all my Sci-fi novels in the 60s?" Because they would have expired in the 80s, long before they would become viable for implementation. Patents only last 20 years.

    Being scorched by molten metal at high velocity is not how I'd want to go. I wonder if this would be ruled inhumane. As if it's any worse than a nuke, just on a smaller scale.

    Have flamethrowers and napalm been ruled inhumane?

    In any case, molten high velocity metal is already widely in use in anti-armor weapons. In the case of spalling, http://en.wikipedia.org/wiki/Spall, the molten metal is from your own vehicle not the weapon.

    Explosively Formed Penetrators are different from regular High Explosive Anti Tank rounds, which do form a molten jet. In the EFP, the charge is in the shape of a shallow dish, and it forms the lining into a solid penetrator. It works at a much greater standoff distance than a regular HEAT, and is not as much subject to disruption by reactive armor. It is not as good at penetrating the armor of a main battle tank, but is quite good at destroying vehicles and emplacements with lighter armor.

    In a conventional HEAT, the charge is in the form of a narrow cone, and the liner is projected as a narrow jet of molten metal. It must explode at the correct standoff distance and the correct angle to be effective, but when it works it works quite well against even heavily armored vehicles.

    No. In the U.S., the government can file for trademarks and patents and the only way they can be used by the general public is if they are licensed. The money then (currently) goes into the general fund. It is not public domain.

    The bronze-age myths persist because religions are ideological rootkits, most of your brethren have been rooted, and the rootkits all include strong imperatives to infect one's offspring. Anyone intrigued by this idea who hasn't read Neal Stephenson's Snow Crash, go read it.

    Your argument is known as "God of the Gaps". The problem with it is that as science advances, the gaps get smaller and then so does your God. It also unnecessarily puts religion at odds with science, when they can quite happily operate separately - Science in the land of reality, and religion everywhere else.

    Your claim that science is a belief system is to fundamentally misunderstand science. Science is a method of inquiry into the natural world, the only one we know of, that can identify objective truths. It takes zero faith or belief or anything like that to accept the outcomes of the scientific method.

    Finally, you are also making an argument from ignorance in your discussion of the big bang. The bottom line is we don't know how it all happened. We don't know what there was before. We don't even know IF there was a "before" at all. If time began then then most of your assertions disappear. Just because you don't understand something isn't a reason to say "god did it".
