From a sleeping bag that charges your gadgets to entire buildings warmed by body heat , scientists are harvesting the heat emitted by humans as a source of renewable energy. But the latest development in thermoelectric energy generation doesn’t come from a high-tech lab at MIT; it comes from Ann Makosinski, a 15-year-old Canadian girl who developed a flashlight that is powered by the heat from a human hand . With the aim of reducing the number of single-use batteries that are thrown in landfills, Makosinski developed the innovative flashlight, which can be developed cheaply and deployed to populations that can’t afford electricity to light their homes.

While other 16-year-olds were watching TV and hanging out with their friends, St. Petersburg, Florida-native Evie Sobczak was hard at work in her garage developing a device that turns algae into fuel. Sobczak told the Tampa Bay Times that she spent about an hour each day tinkering in her garage on the project. After about four years, her hard work paid off , as Sobczak figured out a way to harvest and extract algae oils — without using any chemicals — and turn them into biofuel. And the technique is 20 percent more efficient than existing technologies. Sobczak’s algae-to-biofuel invention recently won first place at the  Intel International Science and Engineering Fair in Phoenix.

Comments Off on Scientists 3D Print a Lithium-Ion Battery the Size of a Grain of Sand

As technology advances, gadgets and gizmos are becoming smaller and smaller. From medical devices to bee-sized robots , developments in engineering have made for incredibly tiny electronics. To accommodate these diminutive devices, researchers at Harvard University and the University of Illinois at Urbana-Champaign have successfully 3D printed lithium-ion batteries the size of a grain of sand. They were able to use a printer to fabricate interlocking electrodes each about the width of a human hair. Their results have been published in the June 18 edition of Advanced Materials.
