House Paint Foils Wardrivers
Ant writes "Security-minded U.S. decorators' supply outfit, Force Field Wireless,
claims to have developed a do-it-yourself solution to the international menace of
marauding geek wardrivers: DefendAir paint 'laced with copper and aluminum fibers that form an electromagnetic shield, blocking most radio waves and protecting wireless networks.' According to the South Florida Sun-Sentinel's report,
one coat of the water-based paint 'shields Wi-Fi, WiMax and Bluetooth networks operating at frequencies from 100 megahertz to 2.4 gigahertz", while two or three applications are 'good for networks operating at up to five gigahertz.' However, there are downsides to this." Since it's a water-based paint, exterior use is only recommended for people who want more copper and aluminum in the soil surrounding their house.

Just because it's water base doesn't mean it will wash away with water. Latex paint is water based... Once the water evaporates the emulsion hardens.
they make tin foil hats for houses now...
Paint your house with this stuff? Psshh, I take care of the SOURCE of the problem, I shoot war drivers with my paintball gun.
My dad was a war photographer in Korea. He had some level of clearance and once was working at a base on the coast of Florida photographing experimental weapons. He was walking around the facility and started talking to a major. The major was complaining about the fishing boats close off the coast, saying that they were known communist spies doing surveillance of the bases secret operations. The nature of the operations made them need to be outside and there was not much they could do about keeping the spies from photographing their operations from the fishing boats.
My dad suggested that they build a pipeline around the base and pump extremely hot water through it. The steam would keep the spies from getting clear photographs of the bases operations.
Ever been to the airport and notice that distortion coming off the top of the jets in the summer? The waviness is caused by the steam and heat coming from the plane. This is the basis for the pipeline.
The major had the pipeline constructed and shortly after the fishing boats stopped snooping around the base. Think of it as a photographic firewall...
Its not that OT when you think about it.

This is great, unless you YOURSELF want to connect from the outside, like from your backyard.

This seems also to be an ideal product to increase the chances of your house being struck by lightning, too.

How will you cover areas such as windows? If this doesn't cover the windows, war drivers are not foiled.

For proof, go stand in front of your microwave oven with the door closed, heat a glass of water for a minute, then go reproduce. If your children are born with n arms, where 1 < n < 3, the EMF was blocked.

En..cryp..tion..? What is this newfangled devilry?!

I love this stuff! I use it all the time to paint my tin-foil hats to look more like hair. You know, like in Calvin and Hobbes.
This flies in the face of science.
Take a look inside your walls. I'll bet you've got thermal insulation in there that is in those rolls sandwiched between aluminum foil. That will put a pretty good dent in the UHF and up, but the RF will leak out elsewhere.
Notably, the corners of your house will act like corner cubes maximally reflecting the energy back to the emitter itself. If the emitter happens to be your laptop then you are going to get the majority of the radiation passing through you on each round trip bounce.
as it happens, the wavelength is near the wavelength of your microwave. The microwave is tuned to optimally excite the rotational frequency of aqueaous water. The 2.4 Ghz is slightly off the optimum but You are inhogenous enough that you probably absorb quite well in this region. The rest of the dry materials in the room wont be doing much absorbing. Thus you will become the primary fate of all the radiated energy.
so you lose on two accounts: 1) high field strengths 2) all the energy resonates around till if finds your testicles.

Your father's scalding water scared all the fish away, you insensitive clod!
The more stupid the mistake the less people want to admit it - it took many years before aluminium was ruled out as a contaminant, but since the aluminium link had been in the newspapers for years we are stuck with another urban myth (just like the wartime carrot nightsight myth - you can't magically boost you night vision with carrots (Mawson didn't get better vision fron a near lethal dose of vitamin A), but it was the excuse to avoid admitting that radar existed in WWII).
This time a bit more litterally. No one wants to paint over their transparent light-holes!
