    this would be great and this might help not only w/hurricane winds but possibly tornadoes as well.

    now, here’s an interesting question, with technology like this, can we translate that to power for the house as well? if we can harness the power of the wind in a vortex, can we redirect the power through mechanical engineering for power to the house?

    Do you have a website that would allow me to look at what you’ve created? If not, is there somewhere that i could look at the application b3eing applied to a roofing system?

    if you look at the article, there is a website listed for her master’s thesis but the download of the version can only be downloaded from the vt files. it would be nice to see the actual device.

    I wonder if it would be worth offering a discount to homeowners that install these devices. If it prevents a huge payout, a small discount would be a wise investment.

    Good idea; only problem is the system is designed for membrane roofs (generally commercial flat roofs).

    Would there be product liability coverage if the downward force created on the building through the device (which is directly proportional to the strength of the wind) collapses the building it is attempting to protect?

    Over the past several decades we’ve spent billions of dollars replacing roofs (some more than once)due to damage from windstorm. I find it hard to believe that our advances in technology and our great engineering geniuses have not come up with something like this before now. It’s even more disturbing when a student has to propose a solution with this potential magnitude. To make matters worse, wouldn’t you think insurance carriers would fund a study for a solution to PREVENT having to incur these losses?

    Having worked multiple hurricanes I’ve been frustrated with the public’s refusal to pay an incremental cost to prevent catastrophic damage. The building trades complained that adding hurrican “straps” to hold a roof on would inflate the cost of a house by a few hundred dollars and people wouldn’ pay for it. “That’s why they carry insurance”. Let the carrier replace it. ALL new construction should REQUIRE them or this new “vent”. Sometimes it seems that our society is very slow to evolve on some issues.

    Thanks geek for the picture. This sounds like a great sales promo. I have serious doubts about this.

    Anyone work as an adjuster in the Hurricane Katrina affected area? I would like to hear your opinion on this vent.

    If this vent is for commercial metal buildings, I did not see many newer metal building’s roofs give in from Katrina. What I personally saw was that the roll-down doors gave in from the wind.

    Would be genuinely interested in opinions.

    Thanks.

    theory and tests prove that it’s successful on roofs – but it appears they only tested on flat roofs. what about those pitched ones? not everyone’s home is going to be a flat one. how high a pitch do you think it can help?
