It looks like someone has a similar idea but, i was watching QVC where they had portable jump start batteries for sale. Well my idea is to have a permanent back-up battery built in your car. When your car is running, excess electricity can be sent to it, if needed to keep it charged via a relay. But when the car is off the battery will be disconnected from the car. Then one night you leave your lights on and kill your battery, you simply flick a switch and start your car using the...

A device that would retro-fit onto the front wheel wells of cars and trucks that would hold a small container of sand which could be activated during icy road conditions when brakes are applied. The sand would disperse in front of the tire allowing for better traction. This device would also assist in sanding roads for motorists without the device. Purdy easy to do n' might just save a few fender benders.

Speed bumps that are filled with water, made of rubber so if you drive slow the water has time to move to other places than under your tires. But if you drive fast you will feel the bump.

Car tags that light just like store signs, connected to the electric system of the car. They can be any color.

I know that in every car there is a center console and it's useful for small storage. Well, I think we all would like a safe place to put our important things, especially for the majority of us who drive and for those who travel. I think of the center console as a safe, so why not build it to make it more secure? Have an alarm to lock it in it's place so that no one can break into it. Of course, the car would have to be some what computerized. Also, there should be an alarm for the car to...

How about putting a chain for locking up your bike inside the bike's frame so when you need it, you can just pull it out?

Aircraft safety is now a big issue. Hundreds of lives can be lost at one time due to small mistakes or failures. If the plane is inevitabaly going to crash and there is no way to stop it, at present the only thing to do is to sit tight and hope you survive. My idea is as follows: There is a device (a larger version of a pilot ejection seat) that blasts the whole passenger compartment away from the wings and engines. The rocket propellors are situated at the front and the back of the...

People like going out but there are a number of us who don't like walking around i was thinkng that we could move the flat escalators (that you get in airports) outside into the pavements/sidewalks and you just press a button when you want to get off and then you wait for another one to stop depending on how far you wanna go you won't have to walk much.

The idea is to develop a new ECG detecting steering wheel. The steering wheel's sensors will detect abnormalities in the driver's heart rhythm, alerting the driver through a display monitor. The system will include a monitor on the in-car navigation system that will display a chart of the driver's heartbeat and electrocardiogram, allowing the driver to keep constant tabs on their heart rhythm.

Why not capture the kinetic energy of subway trains and use it to supplement the power the trains consume during startup. The system would operate through a variation of regenerative braking. A flywheel attached to the rail system would harness the energy of trains as they slow for a station, converting it to electrical power. The harnessed power could then be used to give the train a boost to get moving again.
