Wheelies at Work

February 6, 2013

You’ve probably heard of biking to work, but biking at work is a whole other story.  A recently invented work desk, called the WeBike, makes people work for their, well, work.  As you sit at your desk, you pedal the bike, which generates the electricity to power your laptop, printers, phones, and other electronics.  It seems like kids could use this thing even more than adults, to power all the batteries you need for your toys.  And imagine if you had these bikes at school…could it do your homework for you?

Wee ones (counting on fingers): If you pedal fast enough on your WeBike to power 2 iPads, 2 pencil sharpeners, and 2 remote-control cars, how many electrical gadgets can you power?

Little kids: If you pedal for 13 minutes to recharge your electric guitar and another 8 minutes to get the batteries going in your remote-controlled helicopter, how long does it take to recharge both toys?  Bonus: If you have 3 toys that each use 3 AA batteries, and pedaling for 2 minutes can recharge 1 battery, how quickly can you recharge all those batteries by pedaling?

Big kids: What if this thing could actually do your work for you? If pedaling the bike can make your computer type up 5 pages of homework in a minute, how many pages could you crank out in 1 hour?  Bonus: If you can pedal out 5 pages per minute, how many minutes to write a 75-page book report?

 

 

 

Answers:
Wee ones: 6 gadgets.

Little kids: 21 minutes of pedaling.  Bonus: 18 minutes.

Big kids: 300 pages.  Bonus: 15 minutes.
