Citywide geothermal heat pumps Printer Friendly Version
The most efficient means of heating a house is by using geothermal heat pumps. Check the link below:
http://www.eere.energy.gov/RE/geo_heat_pumps.html.
The air going into your house runs through an underground tube, and becomes warmer. I.E. less energy required to get the air warmer. Heat pumps are kind of expensive to build, and it takes about 5 years for the energy savings to pay for the initial cost. Most people move within 5 years so the incentive isn't there to install them. City lots are mostly too small for geothermal heat pumps, so city governments should automatically install them under streets just like sewers. Homeowners would just plug into the common heat exchanger, and heating/cooling costs/energy use would decrease dramatically.
Reward: I'd like a city to name a park Bluecube Park.

Name Tags Printer Friendly Version
If everyone wore name tags when they went out of their house, then maybe we would be more friendly to each other. Then there would be no reason not to say "hi Bob" when walking down the street. Or "hey Sara" how's it going, while you are in the elevator.

Home tresspasser photographer Printer Friendly Version
Battery powered, solar recharged, laser diode creating a barrier around common entryways into your house / doors / windows or even to protect the immediate area around your home (yard). The purpose is that if the laser barrier is broken by a trespasser, photos will be taken of the area where the laser was broken (say five pictures with one second delay) for each laser break. Infrared lasers will allow it to be invisible to the naked eye. The device should automatically delete pictures that are older than a variable amount of days. The days should be determined by the owner during the setup.
Basically if your yard was protected, you would have a laser crossing your yard near your house. The camera is digital and mounted on the house facing the laser barrier and is equipped with a flash. Since it is digital, it will save pictures on a standard flash ram or memory stick (whatever). The flash RAM should not be located with the camera but rather it should be in some other central and safe location. The flash is intended to notify the trespasser that their picture has been taken and to possibly alert neighbors and you and your family of possible danger. Cameras can be fixed to the inside of windows to protect from the elements and allow easy battery change out (like a fire detector).
The purpose is to both scare away trespassers and to identify them for the police. I write this in response to the overwhelming danger to our children from sexual predators. The lasers on the windows could also sound an alarm. This product should be a stand alone set that ANYONE could buy at Wal-Mart or similar discount store.
It may also identify the dog that poops in the yard in the middle of the night.
Reward: I would be rewarded if it was made and people were safer.
