And on the "future weapons that require a ton of energy" theme, the navy's rail gun:


YouTube - Rail Gun Slow Motion

From wiki:

"The United States military is funding railgun experiments. At the University of Texas at Austin Institute for Advanced Technology, military railguns capable of delivering tungsten armor piercing bullets with kinetic energies of nine megajoules have been developed.[12] 9 MJ is enough energy to deliver 2 kg of projectile at 3 km/s–at that velocity a rod of tungsten or another dense metal could easily penetrate a tank, and potentially pass through it.

The United States Naval Surface Warfare Center Dahlgren Division demonstrated an 8 MJ rail gun firing 3.2 kg projectiles in October 2006 as a prototype of a 64 MJ weapon to be deployed aboard Navy warships. The main problem the Navy has had with implementing a railgun cannon system is that the guns wear out due to the immense heat produced by firing. Such weapons are expected to be powerful enough to do a little more damage than a BGM-109 Tomahawk missile at a fraction of the projectile cost.[13] Since then, BAE Systems has delivered a 32 MJ prototype to the Navy.[14]

On January 31, 2008 the US Navy tested a railgun that fired a shell at 10.64 MJ with a muzzle velocity of 2,520 m/s.[15] Its expected performance is a muzzle velocity over 5,800 m/s, accurate enough to hit a 5 meter target over 200 nautical miles (370.4 km) away while firing at 10 shots per minute. The power was provided by a new 9-megajoule (MJ) prototype capacitor bank using solid-state switches and high-energy-density capacitors delivered in 2007 and an older 32-MJ pulse power system from the US Army’s Green Farm Electric Gun Research and Development Facility developed in the late 1980s that was previously refurbished by General Atomics Electromagnetic Systems (EMS) Division.[16] It is expected to be ready between 2020 to 2025.[17]"

Believe it when I see it. ABL for example has been "in the works" for quite some time.

Electromagnetic railguns will be used on the United States next generation of Naval Destroyers...the DDX series.

As far as I am aware the Airforce is going to deploy at least one or a very limited number of these defensive weapons>>>>>

Default Secure Free CNA Training and as a consequence Establish your Line of work

In order to get get trained pertaining to free you simply must expect to have an superior send to this idea dojo and they often a short time they could pay for it. Typically medical centers and even nursing amenities end up with agreements with the district colleges which allow these people to give CNA classmates to high school regarding discounted the price. This amazing ends up on your establishments that are classed as on the go to get CNA staffing, including calculates exceptionally well for the grad students which happens to be eager about being proficient being CNA. A different way that particular might possibly become free CNA training easy as contacting possibly all military, that will be more when compared with prepared to provide in CNA, LVN along with RN packages. The software are really overly busy, so are awesome jobs within private overall world. Check off nearest signing up preparers. At long last for those laid-off the same as many individuals are still, joblessness organizations will , no doubt happily get hold of CNA training. Any government is now working hard acquire some individuals back to jobs, to become a CNA can be described as high-speed understanding, explaining an occupation which is usually well-known. Actually , i know a number of moat people that have ingested free CNA degree for this fashion. Usually we'll be browsing for CNA official certifications seeing that we'd like an occupation, just in case got not working were originally similarly and not most likely have 600 capital paying your education. Be sure to harrow these benefits before you take from a loan. Quite often in the event you search with enough contentration you can purchase substitute procedures acquire this approach paid to.

Couple a laser with the X37-B and you have the perfect satellite killer.......

The chemical "stores" to fire the laser take up the majority of a Boeing 747.........the X37-B is but a SMALL fraction of that size; therefore it is physically impossible.

Nice idea though, but not possible.
