Wind energy on a small scale still isn't very accessible to the general public. I hardly see people with a windmill on their roof. Embossed Design might change that with their Zephyr concept. The Zephyr is an easy to install wind generator that fits on rooftops and walls. It's silent, doesn't need much maintenance and is relatively cheap. I love concepts like the Zephyr, they keep things on an understandable scale. It wouldn't surprise me to see the Zephyr or a similar product being mass produced in the near future.
