What is the most efficient device easily around us? Also Less is MORE!
Does anyone know the % of efficiency of common items for people to experiment with?

Obviously a car is 30% efficient and too big to deal with it. But what about other things smaller and easier to access around the home? A motor in a dvd player, a cell phone motor, a shake flashlight, solar panel, led light, CFL light, etc.

In short what is OVER 60% efficient that is commonly accessible?

Also when people try to make big elaborate free energy devices with many moving parts and components I feel that is the worst thing they can do. Because the more moving part or components, the lower the efficiency gets. A free energy device has to consist or as little parts as possible I feel. Every time there is more than one moving part or an electrical component like a diode or something you have a loss. And a loss is not minus a number but a percentage loss. Every time you put an extra component that can be another loss of 5-50 percent loss. Air friction, physical friction, component loss, energy not efficient, etc will be under 80% efficient each part, and multiply that by the amount of parts which your device will be at a stand still. As if a multi pulley system with every pulley rusted to contend with.

Even copper coils have a loss of energy dispersing out off it not uses, as if pouring 2 gallons of gas in a funnel that can only take 1 gallon a minute. Or using 1/2 a solar panel for energy while the other is wasted in the shade.
