Questions for proponents of the DEW theory:
What is the required size (MW, physical) of the DEW?
What was the source of energy for the DEW?
Where was the DEW placed?
What is the source of your information?
Why should this source be considered reliable?

[Studies and scaling experiments have shown that a liter of a missile's
material can be destroyed in a few seconds with 1 MW of laser power. One
liter corresponds to a hole with the dimension 10cm x 10cm x 10cm which is
generally enough to structurally disable the missile. Missile destruction
can be achieved in different by an explosion of the missile warhead, or an
aerodynamic instability causing the missile to breakup.--Konstantinos

[Whether Tesla's idea was ever taken seriously is still a matter of
conjecture. Most experts today consider his idea infeasible. . . .
In 1958 the Defense Advanced Research Projects Agency (DARPA) initiated a
top-secret project code-named "Seesaw" at Lawrence Livermore Laboratory to
develop a charged-particle beam weapon. More than ten years and twenty-seven
million dollars later, the project was abandoned "because of the projected
high costs associated with implementation as well as the formidable
technical problems associated with propagating a beam through very long
ranges in the atmosphere." . . .
In the late 1970s, there was fear that the Soviets may have achieved a
technological breakthrough. Some U.S. defense analysts concluded that a
large beam weapon facility was under construction near the Sino-Soviet
border in Southern Russia.
The American response to this "technological surprise" was the Strategic
Defense Initiative announced by President Ronald Reagan in 1983. . . .
Today, after a half-century of research and billions of dollars of
investment, the SDI program is generally considered a failure--"A Weapon to End
[One major problem with laser weapons . . . is their high electric energy
requirements. . . .
This problem could also be lessened if the weapon were mounted either at a
defensive position near a power plant, or on board a large, possibly nuclear
powered, water-going ship. A ship would have the advantage of water for
energy weapon," Wikipedia]
[The three primary technologies being followed as direct energy weapons
include Lasers, Millimeter Waves, and Microwaves. . . . The Department of
Defense (DoD) does not currently advertise the development of any weaponized
microwave systems, however developmental experiments continue. . . .
The Status of Futures Index or SOFI is one method used in future studies to
help predict the path of already existing technologies. . . .
The Navy currently fields an HPM system designed to counter Improvised
Explosive Devises (IEDs). The Navy's Neutralizing IEDs with RF (NIRF) system
is currently in use in Iraq.
. . . HPMs are most useful against electronics,
. . . like chemical lasers it takes multiple truckloads of equipment to
generate that level of power. The US Air Force High Powered Microwave
device, Shiva Star, can generate 1 terawatt of power. However Shiva Star is
a test machine only. Mobile, single shot weapons can generate over 10
Gigawatts, but only have a range of about 500m. . . .

[Lithium-ion (Li-ion) batteries are the heir-apparent to lead-acid and NiCd
batteries in many aircraft applications. They are available in several
different chemistries and can be classified as either high power or high
energy batteries. High power Li-ion batteries have high power density (1500
W/kg), moderate energy density (70 Wh/kg), and reasonable cycle life
(2000).--Christopher Eiting, "QynCap

[Currently, the free-electron laser project produces the most-powerful beam
in the world. If it gets up to its ultimate goal, of generating a megawatt's
worth of laser power, it'll be able to burn through 20 feet of steel per
. . . the Navy doesn't yet have the systems to divert the amount of power
from its ships' generators necessary to operate the laser, but anticipates
it will by the 2020s.
There are still a lot of obstacles to getting the free-electron laser onto a
ship. The 240-foot racetrack that Neil built at Jefferson Labs - a scale
model of one that's underground here, seven-eighths-of-a-mile long - is way
too big. Boeing has a contract to build an initial workable prototype by
2012, but by 2015 the racetrack has to be much, much smaller: 50 feet by 20
feet by 10 feet.--Spencer Ackerman, "Unexpectedly, Navy's Superlaser Blasts Away a

[All this means that it's not possible, or indeed meaningful, to say exactly
what would be needed in terms of design or cost to get this idea to work.
But Vasile and Maddock do manage to establish that if, say, we discovered in
ten years time that Apophis really was going to strike, it should be
possible to implement a strategy like this based more or less on the
technologies already to hand, without any fear of bankrupting the
economy.--Philip Ball, "Laser treatment for Earth-bound asteroids," BBC News,
