Re-Innovation's LED bar graph and energy bike were hired by Bristol University Sustainability department for use at the university freshers fair.
The pedal generator was used as a power generation challenge, with the highest output power winning a fair trade hamper. This meant that it was tested to the max with over 10,000 students visiting the fair and lots of them trying to pedal as fast as possible.
There were a few teething problems (mainly due to difficulties mounting the display onto the backing board) but it all worked well with one student generating 270W of electrical output power! I didn't even know it went up that high!
I only managed to get one good photo of the generator in use...
