Securing audio/visual equipment Printer Friendly Version
This is a very simple concept but I'm amazed that I haven't seen it yet. Why can't we have smart cards for audio and visual home equipment? Why not a smart card activated hi-fi? It won't turn on without the card and won't turn off unless you remove the card... Or what about the removeable fascia that was used for a car stereo? why not have a fascia that operates both your home and car stereo? I prefer the smart card idea though. If you lose it all you have to do is bring your receipt to the store and they can 'chip' a new one for you - maybe it would be linked to the serial number of the equipment? It just seems to me that since so many homes get broken into why can't your stereo or vcr or TV have that extra level of protection that makes them useless if they're stolen?
Reward: Getting the smart-card protected device for free would be reward enough for me.

Travel Long Distances with Electric Vehicle Printer Friendly Version
In my home, we use cooking gas cylinder. If we create big cylinder electric batteries for cars and always carry two of them, then as soon as ones charge gets low, the other charged battery should take over and we have to just replace former with a charged one. Which means we should have at least three, i.e. one will be always charging at our home.
Or all these batteries could belong to a big power company and all gas stations could become battery chargers. I mean when we are on a long distance travel and one of the batteries gets low, all we have to do is go to the nearest gas station and exchange our battery with a charged one. Thus we will pay only for the charge and not wait for charging our batteries.

Modular power generation. Printer Friendly Version
This idea is based on very old tried and true principles of physics. Hydroelectric power has been around for a long time. The man who invented the modern world, Nicola Tesla, also invented a very novel turbine. Imagine the average home owner putting a large low slung water tank on top of their house. A 2 inch ID pipe descends 8 feet into a Tesla Turbine. The Tesla Turbine outlet goes into another tank. At the top of the upper tank is a sensor that turns the water valve to open. At a point lower is a sensor to turn the valve closed. Elevated water = energy. The Home owner invests enough money to trickle charge the system at first. A small pump powered by some solar cells will pump water back to the top tank. The generator will only run when the upper tank is full and turns off when there is insufficient water pressure. This won't run continuously at first but it will run a meter backwards enough times during the month to save a significant portion of money on electricity. The savings can be applied to more water pumping devices. I have a slew of ideas for those. Stirling engines powered by parabolic mirrors, bales of hay, the difference in temperature between ambient and 6 ft under, etc. Make the devices modular and readily addable. Over time, by adding pump modules to the system, the home owner will have continuous free power. Since this technology does not depend on expensive batteries or fuel cells it is cheap enough for most people to afford readily without loans. Because it is modular it is feasible to be done by most home owners in the developed world.
Reward: Continuous free power. What more can one ask for? Ok, I would like a job in the industry created. That would be great!
