Solar panel retrofit to wind turbines Printer Friendly Version
Large windfarms generally take up a lot of land and that space on the turbine blades or the top of the generator house retrofitted with flexable solar cells could easily increase the amount of power produced without taking up any more land. Anyone else have any other ideas on increasing the renewable power production on current power installations shout it out.
Reward: More power from the same amount of land space

Long Life for Electric Bulbs Printer Friendly Version
Over the number of years that I have lived, I have realized that, most of the time we loose filament of electric bulbs is while switching the bulb on. That must be because of sudden heating of cold filament to an instant brightness. So if we create a second electric bulb holder that fits on any existing bulb holder such that it doesn't instantly ignite the bulb to full brightness but rather smoothly increases the electric current to the fullest, then we would save a lot of money and resources of producing electric bulbs. And poorer areas where only bulbs are used will be glad to buy such a product.

Hand Crushable Cans Printer Friendly Version
We should add several wrinkles or ridges to our cans so that we can crush them by our own hands with no chance of them being crushed incorrectly and we get perfectly flat, crushed cans every time.
This saves the common can recycler time and gets rid of the frustration of having to crush them with your feet. If we run ridged dents around the can from top to bottom we can crush them by hand easily, completely flat and without effort.
Reward: Credit
