Interesting technology, except I can't help but think that you're literally painting yourself in a corner.

Put another way, this is akin to locking down your house so tightly that not only can no one get in, but you can't get out either.

For the purpose of keeping Wi-Fi private, the blocking of signals is what you want -- but what if the time comes when you need to leech off the signal of others?

You guys know that wireless is 2.4 GHz and 5.2 GHz for the newer stuff right? The "old" paint that will block signals below 50 GHz is way more then enough....

im not sure "honey, we need to repaint the house because im too lazy to set up a WPA encryption" (in a packed neighborhood) is a good enough excuse... unless they have the color your wife loves!!!!

Yea, that stuff has blocked wifi for some time now. A bit off on that part I think.

A 10 chars, upper and lower case letters only, random passphrase (for AES-128) assures you a computer with 2 4870x2 would still need more than 20.000 years to hack it.

Just use 20 chars to be on the safe side and forget it.

Wouldn't this be counter-intuitive unless you only painted the outside of your house or the walls that line the outside? Else you'd just be trapping the signal from the router into a single room in your house, no?

well.. once youve got wifi its hard do go back. its a little counter productive if you already have a router set up. but the cellphone question is a good one.

So now I need my building inspector to check the paint in the house to make sure I can recieve radio, TV, cell phone, etc. signals before moving in huh? It's not like you can just paint over to undo the previous changes. This idea sucks for residential use.

Or how about you live in a condo and all the neighbors above, below, left, right, and opposite do this? Then you are screwed.

Now for commercial applications, this may have some merit, as long as landlines are made easily accessible in case of emergency.

[citation][nom]ira176[/nom]What about your cell phones or home wireless phones?[/citation]
wireless phones connect to a reciever that is indoors, so that isnt a problem.. and another problem is that you cant get rid of the paint as easily as you put it on..

cell phones operate below wifi frequencies, otherwise their signal wouldn't have the penetration power that it does...so they'd be blocked too.

Not only that, but TV and radio signals using antennas to receive will not pass through.

The positive side is that you'll have a room 'free' of the millions of radiation that flows through the air every second.
It should be able to reduce the risk of cancer, but then again, perhaps the paint itself is more cancerous than the radiowaves.

I wished they would create this product as 'transparent paint', so I won't need to redo my whole house due to the inavailability of color; and perhaps I could just paint part of a wall where my router is placed.
Sometimes a small shielding would be enough to stop neighbors from leeching.

uhh this is a joke right.
Somebody this is an aprils fools joke right!!

Painting your house with thermite (iron-oxide aluminium powder mixture ) is a really bad idea. Gee I don't like my nieghbors leeching my wifi, so I think I will paint my house with rocket fuel!!!

Also since 2.4 ghz is way below 50ghz existing paint is good enough.
the only stuff above 50 Ghz is satellite most of which is yet to be deployed.

I think I would prefer lead based paint. As long as I resist chewing on the molding I think I will be okay. Thermite on the other hand will burn very hot and very quickly.

Hey if i cover my house in stealth paint does that mean it will sell faster due to being able to travel at ultrasonic speeds?

Hows this for a marketing stroke of genious.
