Electric Clothes
Now that the weather is getting warmer, it is easy to realize which parts of your body are warmer than other parts; the difference between the armpit and elbow, for example. Wake Forest University is working on a fabric that takes advantage of those natural differences in temperature across a piece of clothing (up to 10 degrees in places) and turns it into electricity. Just by sitting still your shirt or pants could help recharge your cellphone battery. “According to the fabric’s creator, David Carroll, a cellphone case lined with the material could boost the phone’s battery charge by 10 to 15 percent over eight hours, using the heat absorbed from your pants pocket.”
Building a Better Mousetrap Bike
The bicycle, one of the most popular and cheapest methods of transportation, is in need of a change. How else is it to compete with other methods of getting around? Well, by making a bearing system that allows the bike to lock, you make the bike unrideable since it can’t be steered. The lock is inside, so the only way to unlock it is to destroy the bike, which makes a for a pretty good disincentive to steal.
Another innovation has to do with the ever-present and greasy chain. Currently popular in China, bikes with drive shafts including an internal gear system will replace the need for chains.
Finally, what about leaving your bike out in the rain or lugging it up stairs? How about thermoplastics? These materials are lighter, cheaper, and don’t rust. They will be ready to hit the market soon.
Have Your Cake and Eat It Too (Including the Box It Came In)
(This is a personal favorite of mine.) Harvard bioengineer David Edwards says, “We’ve got to package in the same way nature does.” How do we do that? Well, he thinks through designing containers and films he calls Wikicells. The New York Times describes it this way.
Yogurt will be encased in a strawberry pouch, for instance. You could wash and eat the packaging, like the skin of an apple, or you could toss it, like the peel of an orange, since it’s biodegradable. The newly wrapped ice cream and yogurt will be available later this month at the lab store in Paris, with juice and tea coming within the next year or two.
Sounds delicious!
