A Military Advancement in Bullets Printer Friendly Version
A bullet shot from an automatic machine gun has tracers but, no way to know when they have hit or miss their target. If we apply a flint tip to the bullets then we know when they are hitting the target and when they are not. They have exploding tips but those do not give off a spark or report to visually see the hits and misses on metal targets. The exploding tips are to fragment and become shrapnel inside enemy bodies to do more damage. My bullets show hits and misses on any target that will spark and explode into seeable reports like tanks, planes, or metal type flak jackets and protection. A much better bullet.

Train Cars Printer Friendly Version
It seams obvious that the most serious traffic accidents happen at the highest speeds. The idea set forth in this post can be modified for town driving, with increased technology, but I figure I will list what can happen “today” on the highways and freeways.
I have commuted for many years in bumper to bumper traffic. Usually 1.5-2 hours a day. I often wondered if there is an apparatus that can be connected to the back and front frames of cars so that they can connect and disconnect like a train.
The basic idea is that you would save fuel and traffic accidents by having every third car running at a much higher gear, at a much lower RPM, and the other cars would essentially be “off” or in neutral.
All the breaks would be matched together through the hardwired connection that allows the cars to connect and disengage.
This would mean it would have to be 3 lane highways, one lane (far left lane in North America) that would be at 150km/hour, then a middle lane to slip stream down/up, then an exit lane.
Drivers would enter their destination into a telecommunications computer in the car, pull into “slip stream up” then the car would send out a signal detecting the “group” it would join (if traffic wasn’t bumper to bumper, otherwise a break in the group would allow for automated connection). The user then would get a signal for an “auto engage”, and the car would pull into the fastest lane, and connect to the other cars.
0 distance between cars, allowing for more traffic on the roads, and increased speeds because all breaks work in unison. The strongest engines are noted and used, and the drivers get an automated deposit in their account for added gas / wear and tear costs.
Big trucks, most can do this, the ones that cannot get up to speed are designated onto a different route of 80-90km/hr – and the money saved from accidents and environmental costs of running the cars is used to offset “side road” improvements to allow for this.
Either you can use the technology that is being developed today (I have seen shows that talk about magnetic strips being used, but this does not allow for combined breaking nor lower gas consumption) so single cars can be to control the lead cars, or hire professional drivers to drive every day and to report any misuses, abuses, or problems on the road. The inbetween cars can lay back, relax or read on the way to school/work. A warning comes on before engaging and disengaging to notify drivers.
Reward: Recognition, and the ability to read on the way to school/work when this is created!

Fish Finder for My Car Printer Friendly Version
Whenever you see a TV report on floodings there's always some footage of cars that tried to make it down a road where the water turned out to be deeper than they thought, leaving them stranded. This device would prevent that. It would consist of 2 parts, one you hooked on to your front bumper and one that you left in your glove compartment until you needed it. When the need arose you'd pull the remote out of the glover and push a button. This would drop a rod down from the bumper device to the ground (it would have a small wheel on the end of it so it could roll). Once you reached the water the depth finder would look several feet ahead and compare the depth it found to the clearance under your car. If you couldn't make it a warning would flash on the remote. You could also turn the depth finder side to side to see if there was any way to make it down the road.
This device might be a little pricey but it would offer some major peace of mind to drivers like myself who run into roads like this a couple of times a year.
Reward: None required.
