System with non-newtonian dilatent fluid to stop hail damage
A roof protecting system for protecting the roof of a building from hail damage. The roof protecting system includes a roof covering structure adapted to cover a portion of the roof and capable of holding a non-Newtonian dilatant fluid; a deployment system to dispose the roof covering structure onto the roof; and a delivery system for delivering the non-Newtonian dilatant fluid to the roof covering structure.
1. A delivery system for delivering a non-Newtonian dilatant fluid to a roof covering structure for covering at least about portion of a roof, the system comprising:
a storage volume for a solid, wherein when the solid is combined with a liquid, the non-Newtonian dilatant fluid is formed;
a first conduit for delivery of the solid to a control system;
a second conduit for delivery of the liquid to the control system;
wherein the control system controls delivery of the solid and the liquid to a plenum in proportions that can be mixed to form the non-Newtonian dilatant fluid;
wherein the solid and the liquid undergo mixing to form the non-Newtonian dilatant fluid; and
the roof covering structure being fluidly connected to the plenum to receive the non-Newtonian dilatant fluid from the plenum.
2. The delivery system of claim 1 , wherein the solid comprises cornstarch.
3. The delivery system of claim 1 , wherein the fluid comprises water.
4. The delivery system of claim 2 , wherein the fluid comprises water.
5. The delivery system of claim 1 , wherein the roof covering structure is filled to a thickness that provides protection against 3 inch hail.
6. The delivery system of claim 1 , wherein the roof covering structure is filled to a thickness that provides protection against 6 inch hail.
7. A device for protecting a roof of a building from hail, the device comprising:
a roof covering system configured to hold a non-Newtonian dilatant fluid;
a fluid supply system configured to supply the non-Newtonian dilatant fluid to the roof covering system; and
a control system configured to control deployment of the roof covering system and the fluid supply system;
wherein the fluid supply system includes
a storage volume for a solid, wherein when the solid is combined with a liquid, the non-Newtonian dilatant fluid is formed;
a first conduit for delivery of the solid to the control system; and
a second conduit for delivery of the liquid to the control system; and
wherein the control system controls delivery of the solid and the liquid in proportions that can be mixed to form the non-Newtonian dilatant fluid.
8. The device of claim 7 , wherein
the control system controls delivery of the solid and the liquid to a plenum in the building; and
the roof covering system is fluidly connected to the plenum to receive the non-Newtonian dilatant fluid from the plenum.
9. The device of claim 7 , wherein the solid comprises cornstarch and the liquid comprises water.
10. The device of claim 7 , wherein the control system is autonomous and is adapted to receive information from weather alerts and broadcasts, system hail sensors, neighboring systems, and reports of the location and severity of hail.
11. The device of claim 7 , wherein the control system is manually operable.
12. The device of claim 7 , wherein the roof covering system is filled to a thickness that provides protection against 6 inch hail.
13. The device of claim 7 , wherein the roof covering system comprises a plurality of compartments in fluid communication with each other.
14. The device of claim 7 , wherein the control system is configured to control a thickness of the non-Newtonian dilatant fluid in the roof covering system by controlling a volume of non-Newtonian dilatant fluid delivered into the roof covering system.
