Environmentally conscious people are getting a buzz out of a new hand-cranked vibrator that makers say could help save the planet.

The eco-sex toy - dubbed the Earth Angel - uses a small wind-up handle to power up rechargeable batteries inside the casing.

It had originally been planned as a sex aid for Third World countries, but the manufacturers have been swamped with interest from Green followers after displaying the vibrator at an electronics fair in Austria this week.

"We wanted to produce an environmentally friendly sex toy that appealed to all consumers regardless of gender, age or ethnicity," said a spokesman.

I don't get this. Hand-cranked? If I could move my hands quickly, I'd have a boyfriend.
