Thigh Master is a servo-controlled ring of thorns worn around the thigh which pierces the user when she consumes too much electricity! I would love to see Suzanne Somers wearing it! Watch the video here.

From the official site:

While technologists scramble to develop technologies for the production and storage of environmentally friendly electricity, it is also important to address our personal role in conserving energy.

Indeed, thermodynamics shows that we can’t get energy without spending it, and while great efficiencies may be found in energy generation, it is clear that the most substantial way to solve the energy crisis is by reducing demand.

While reformulating lifestyle and habits is usually thought to be the job of media, public relations, and activism, there is no reason that technology should not be central to how we understand, consider, and change our own energy usage.

Project Thighmaster is a system that alleviates this condition by assuring that reminders to save electricity will not go unnoticed, increasing its owner’s peace of mind by setting a penalty for environmental waste.

The system consists of a personal techno-garter — inspired by the Opus Dei cilice popularized in Dan Brown’s Davinci Code — worn on the thigh, communicating wirelessly to a set of low-power sensors measuring the wearer’s personal energy consumption. If the wearer’s electricity use exceeds a certain limit, the device plunges stainless-steel thorns into the wearer’s thigh, a reminder of their complicity in the planet’s demise, and perhaps their own mortality.

Thighmaster aims to balance comfort and discomfort in a meaningful way in order to achieve sustainable change. Packaged in the form of yet another personal electronic device, the system helps people to break out of inefficient consumption patterns. But in addition to decreasing a user’s energy use, Thigh Master can also provide relief for the less easily measured — but no less real — feeling of individual powerlessness in the face of accelerated climate change.
