Charging Phones With Bicycles


The famous Roskilde Festival ends today after four days of cracking concerts, sunshine and good times. First held in 1971 it's one of the premiere music festivals in the world. This year featured a good crop of bands but there is so much action that it's hard to keep track.

One enviro-friendly gimmick was charging your mobile telephone with bicycles. The Climate Community 'neighbourhood' at the festival hooked up bikes to a generator and let festival-goers charge their phones using human-power.

It took about 7 minutes of cycling to charge a phone. Interestingly, it would take about an hour and a half of cycling to generate enough energy to boil water for a cup of coffee. A 15 minute shower and you'll be cycling for 50 hours.

One of the great traditions at the Roskilde Festival is entirely sustainable. The Nude Race is one of the most popular activities and the winner gets interviewed all over the press.


This being Denmark, nudity is not considered odd or strange so the photos of the race are shown in newspapers and on the national news. The above photo is from a newspaper and you can see the whole slide show on their website.

7 minutes only! Wow, that's great. It would be even better though if I could charge my phone on my daily commute, or make a cup of coffee while I'm waiting at a red light :-).

What is amazing is how efficient bicycles are. They take so little power that when that power is diverted to other uses, like heating water, there is not much there.

Which, of course, is what makes electric bicycles the world's most popular electric vehicles. Only 500 watts pushes someone up a hill at 32 km/hr. Amazing.

I'm still trying to work out where they've pinned the numbers on

I'd love to see a dynamo lighting system that during dayligh hours could juice up my phone while I breeze round town.

Surely not far off.

This being Copenhagenize, the tone of smug self-congratulation is to be expected.

You can charge your phone with a dynamo. I have a Schmidt SON Dynamo hub (http://www.peterwhitecycles.com/schmidt.asp) and Zzing device (http://www.zzing.de/English_Zzing/) that converts the juice to USB. It seems to take about 3 days of normal bicycle touring to get enough power to charge my HTC Blackstone just once. Not the best performance but then most of your energy is still used to move the bicycle along unlike the contraption featured in this post where it all goes to the generator.
