Installing mini-weather stations on mobile antennae

I was thinking how it would be nice to install mini-weather stations that could tell air temperature and pressure and possibly predict the local weather for next hour or so on mobile BTS antennae and make them broadcast their measurements to local mobile phone holders through a service so that they could see the outside temperature and possible next hour prediction on their mobile and take wise decision on going out or not.

Air stream producing device

I was thinking if a device that could absorb sun energy from one side and be cool on the other side with a shape that could turn the heat variation inside into air stream can be used as a air conditioner or could be used in conjunction with a turbine to generate electricity.

Spider Feet Hairs as Wall Mounting Pin

I was wondering if the same concept used by spiders and other animals to climb on walls (which has been shown in Spiderman movies) could be used to make a replacement for pins to stick or mount items on the walls and other vertical surfaces.

Combination of BioFuels with Hybrid Cars

I was thinking it would be great to use Biofuels in Hybrid cars to make them even less polutant. Or maybe use Threeway Hybrid cars with Solar Panels, Biofuels and Electricity.

Turning CO and CO2 into C and O2

If Carbon Monoxide and Carbon Dioxide are problem that is causing earth warming then a sustainable chemical or electrical processing unit or filter could be made to turn the emitted Carbon-Oxigen combination into Carbon and Oxigen much the same way a fuel cell but in reverse. It could also mimic Photosynthesis chemical pathway.
