Wouldn't it be nice if someone could produce a Portable Shopping Cart on the lines of a Twin Stroller. As a parent I sometimes find it frustrating loading the kids into the car and unloading the cart, then having to leave the cart at your parking spot, which is a big pet peeve of mine. It is also hard to find a cart that has a dry kid seat when it is raining.

The start of an airplane consumes a lot of energy and is very stressful to the tires. An airplane could be started (and landed) sitting on a magnetic driven carrier which is accelerated by a linear motor installed in the runway. This method will save fuel, tires and reduces noise at airfields dramatically.

I do like the idea of Tunnel Taxi and really want to share with you. Tunnel Taxi is designed for solving problems with traffic. It's a split bus style taxi with a pair of seats on each side that exit into a central tunnel. That central tunnel is there to allow people that ride bikes around the city to pass in the middle of the taxi without having to change lanes.

Why not create a dual-cable lever for bicycles to allow riders with one hand to control the front and rear brakes on mountain and cyclocross bikes. The lever will be adjusted to engage both brakes at the same time or one a bit after the other. There will also be the option either to place the lever on the left or right side of the handlebar.

Self-steering tractors that can travel the fields with the same skill as trained drivers may soon make farms more efficient. The tractor will rely on a GPS system and other sensors to maintain its positional awareness. Specific sensors calibrated for different terrains will allow the tractor to traverse a variety of areas, and the 'smart steering' system will be able to calculate the optimal speed and turning radius.

The bicycle GPS tracker will sound an alert if the bike is stolen, and then help you track it down and recover it. The bike GPS will mount inconspicuously inside the headset of the bike and will be secured by a special wrench. When the bike is parked, the user will active the GPS unit with an electronic key, which will turn on the vibration sensor. If the unit senses vibrations when it has not been turned off, such as in the case of being stolen, it will sent an alert through SMS...

The wheelblades are designed to give wheelchair users more traction and control for better mobility through slush and snow. The wheelblades are basically mini skies that attach to the front wheels of the wheelchair with a clamp lock. The skis spread the weight of the chair and occupant over a greater surface area, increasing stability and reducing sinking and slipping. The wheelblades can also be used with strollers, and the clamp lock can adjust to fit wheels of varying...

I've had this idea for a long time... Ever been frustrated by rude, obnoxious, inattentive, or just plain scary people on the road? To the point you actually wish there was a cop nearby messing with the flow of traffic, just to stop this driver, and save the rest of us? I have the solution! Everyone should be armed with a paintball gun that's filled with paint that disappears as it dries. It would not harm the paint and would not leave a trace after 24hrs. It would be able to withstand...

Currently electric cars use one big motor to run all four wheels as a replacement of the engine. Why don't they use 4 DC brushless motors? 1 on each wheel would make the car more efficient, also using fuel cell stacks would solve power problems, plus because there DC brushless heat output would be reduced. My theory is that a dc motor could be made so that the middle bit with the turns of wire could be inside the wheel itself with an outer casing with the magnets on that the final...

I just bought a dodge hemi express it's a very nicely built eye catcher. A week ago my father asked me if he could borrow my 24" extention ladder. So I went to load it in my new truck and I found a prob. I could lean it on my tailgate or on the cab. Either way I'm looking at some pretty ugly scratches. So like everyone does I put a rag between the ladder and the cab and tied it down. As I was driving I thought "there's got to be a better way". My truck would look rediculous with a headache...
