Photochromic roof tiles Printer Friendly Version
Individual plastic molded photochromic roof tiles that can replace original concrete tiles. Each tile interlinks with the next just like normal but has a hot shoe connection embedded in the tile. The energy collected from the roof can be supplied to a battery storage area and converted to household electricity via an inverter. The amount of electricity gathered would be greater than solar panels as you would have the whole roof acting as a giant SOLAR PANEL.

Tornado proof home Printer Friendly Version
Tornadoes can cause a lot of damage to homes. My idea is that houses or homes are designed in a way that when a tornado comes, the house can retract or descend down below ground level. The top structure could be designed in a way that even if a tornado passes by, no damaged is done to the retracted house. When the tornado passes by, the house can ascend above ground level.

Driveway Cooler Printer Friendly Version
I've seen numerous ideas on here on ways to keep your driveway from freezing but none dealing with extremely hot driveways. In the Sun Belt of the country, it is always rough on the feet in the dead of Summer to walk out of your house bare footed when you have a concrete or asphalt driveway. I think that it would be great to have coils built under the concrete/asphalt in which cold water could be turned on and off to cool this before walking on it.
