Ever smell a durian fruit? Don't. Think of it as nature's stinky battery.
- New research finds that jackfruit and durian, often called the world's smelliest fruit, make outstanding supercapacitors.
- Supercapacitors are useful because they can be used as infinitely rechargeable batteries.
- The study, published in the Journal of Energy Storage, also demonstrates the development of carbon aerogels for the bodies of the fruit batteries.
Technology best serves the user when organic development combines necessity with collective values.
- How are global innovators overcoming the inequality that is forged in the technologies of Silicon Valley?
- Ramesh Srinivasan, a professor at UCLA, points to examples of indigenous communities in Mexico that have created their own cell phone networks, as well as groups in Ghana and Nairobi that recycle discarded devices from the West to make entirely new technologies.
- These groups have successfully decentralized technology governance by using their resources and upping the ante on creativity and innovation.
A microbial organism pulls electricity from water in the air.
- Hidden in the mud along the banks of Washington D.C.'s Potomac River may be a profound new source of electricity.
- The microbe makes nanowires that produce a charge from water vapor in ordinary air.
- Already capable of powering small electronics, it appears that larger-scale power generation is within reach.
