Why not develop a liquid-flow battery that can be used with electric vehicles, enabling them to be recharged as quickly as pumping gas and cutting the cost of current batteries in half? The batteries will consist of a liquid electrolyte semi-solid that will contain the electrodes to provide electricity. Once the energy from the electrolyte material is depleted, it can be removed from the battery and replaced with a fully charged amount. The depleted electrolyte material will be...

A website where people post their ideas to a public domain thereby taking away all future possibilities to hold a patent and more than likely make them a reality/ A website where those with resources can take great ideas from common folk and profit from them while the poor guy sulks about not seeing a dime/A website that destroys all value on intellectual property by removing all buffs.

Seeing all the muck accumulated in the cuffs and collars after a days travelling, I was thinking of a scrubber option built into a washing machine. Maybe a slot where you insert the cuffs and the collar for a time till the buzzer sounds. This would ensure that the shirts' cuffs and collars are scrubbed clean and I have a crisp clean shirt after wash.

If we are able to make small hydro power generators that we can easily generate power from very small streams in our neighborhood and even from a water tank. Let the water, being pumped into the tank, flow on a fan (fixed inside the tank) which can produce electricity. Thus we can generate almost the same energy spent for pumping water into the tank. That means energy used is generated the next moment.

The basic idea is to harness the energy created from the thrust of a commercial jet engine. You would place another turbine behind the main turbine that is propelling the jet forward, except this turbine will not be pushing it forward, instead it will be harnessing the energy created from the thrust of the main engine. As the main turbine is powered by the engine and is running, it creates a powerful stream of air that will turn the second turbine and still let the air flow through. It may...

To decrease costs of resurfacing a road and reduce amount of asphalt used. The idea would be to design a paving machine which uses microwaves to heat up old asphalt on the road and enabling it to be picked up easily. The machine would then remix the asphalt to the proper ratio by adding extra asphalt tar and then resurface the road all in a single operation with the same machine. This machine would eliminate the system used presently whereby pavement is stripped, new pavement is brought in...

I am wondering if there is a debit / credit card with a stamp on it. If user press the stamp he is able to view his account balance in that card itself. This will be really helpful while swiping the card during shopping...

As we know, about 25000 people were killed in building fire in the world every year.Though firefighters are working so hard, death is still going on in building fire. Why are there always so many dead? Because, so far there are not any professional self-rescue instruments provided for the people. So when people are trapped in building fire, the only thing that they can do is just waiting for the firefighters` rescue. However, sometimes death always comes before rescue. If there is a...

Ever woke up late because the beeping noise didn't wake you up? Well, with the alarm spray - when it is time to wake up - it will beep AND spray mist. This way you will have a better chance of waking up at the desired time.

My idea is to insert magnets into the bumpers (front, back, side and rear) of cars. This, if developed properly, could prevent all vehicular accidents. I'm not sure if it's feasible, but I really want to know about the possibilities. Any information would be great.
