It's in society's best interest that we use less energy. |
This doesn't need a vacuum but it does need a moisture barrier and that can be expensive. The biggest barrier to large scale production is simply cost. It costs very little to make a light bulb today. |
We hope it means the end of the light bulb. We don't really want them, they use an extraordinary amount of energy. |
With a future emphasis on manufacturing technology, this structure may provide an important, low-cost and efficient means that will replace incandescent lighting in many different applications. |
