Take a closer look at three Dyson prototypes that will never be.

The headset's applications.
Dyson's V4HF digital motor was developed over the course of three years. The ten engineers working on the project wanted to create a smaller motor with enhanced performance for use in a hydrogen fuel cell.
Dyson's Diesel Trap X007 prototype may remind you of the brand's cyclonic vacuums.
That's because Dyson wanted to apply its cyclone filter technology to diesel fuel engines to reduce air pollution (similar to the way it filters allergens when you're cleaning your floors).
Light bulbs you shouldn't buy
There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
