I am tired of using the scientific calculators in my classrooms and every time I use it for large equations, it says "syntax error" or gives me wrong answers. So I have come up with the idea of controlling a calculator by our voice. Prerecorded commands installed in the calculator helps us to calculate anything by just stating equation. The digits are split according to time and we would use a software called voxox to make it happen.. I have a slide of how it is gonna work.

Bicycle lights that are built into the handlebars. You could press a button on the handlebars on either side and the end of the handle bar would flash and maybe one side of the back of the seat or somewhere else would light up. It could be a safety benefit and give you the ability to see where you were going at night as well.

Imagine this, you find yourself in town with friends without any planning and the question gets asked "whats on tonight, where shall we go". How about a mobile phone application that uses your GPS information in conjunction with event info posted on the web and suggests events or locations you might wish to go to based on the user selecting an activity type. For example, we decide we want to go and eat Chinese, then onto a bar to see a live band playing hard rock. The app scours...

My idea is to make a garden tool that looks exactly like a lawn roller, with numerous spikes protruding from the roller to gather the leaves. This equipment would have a horizontal flat bar fixed across the roller frame to knock off the leaves {as the roller turned} into a collecting box or basket, which would also be secured to the framework. The basket should be easily removable to deposit the leaves in the usual place . All parts would be manufactured from plastic materials [pliable or...

Much like the fabric softener bar that BOUNCE created to stick to the inside of your dryer. This will also stick to the inside of your dryer, but for the sole purpose of getting rid of pesky pet hair without the hassle of rewashing and drying. Instead of it being in bar form, it would come in sheet form and attract the hair like the swiffer duster attracts dirt and must also be able to work for the washer as well.

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 use a pressure water jet to clean concrete garden slabs. For reference, I used 80 gallons of water and the project took six hours. I cannot imagine how much electricity was used. I believe that technology exists to manufacture a sonic cleaner similar to a portable metal detector. If this could be achieved, then world wide savings in water, electricity, and labor hours could be very significant.

How many times have you come out to go to work only to find your cars windscreen/shield is covered with ? My idea is simple, a small box blows heat on your windscreen/shield 10 minutes before you go to work that way you wont have to de-ce it manually.

I had this idea for many years. Most gases from exhaust emission are water soluble. So, before the gases are released in the atmosphere, pass them through water where they will dissolve to form other chemicals. In this way, damaging exhaust gases may be considerably reduced. This principle could be applied to vehicles and industries etc too.

Your cell phone will ring if your car alarm is activated.
