Engineers at Northwestern University have developed a new thermoelectric material that may be the most efficient one yet. The new and improved polycrystalline form of purified tin selenide has all the right properties to make it a practical material fo… Continue reading Extremely efficient thermoelectric material recycles waste heat
Engineers at Japan’s National Institute for Materials Science (NIMS) have developed a new type of thermoelectric generator that produces an electric current through a temperature gradient. By absorbing heat from the Sun on one surface and emitting it f… Continue reading Thermoelectric generator contrasts heat of Sun and cold of space
The electric power grid, as it exists today, was designed about a century ago to accommodate large, dispersed power plants owned and controlled by the utilities themselves. At the time …read more Continue reading Emulating a Power Grid
Engineers at MIT have developed a device that generates electricity using a completely new mechanism. “Particles” made of carbon nanotubes are dunked in an organic solvent, which induces a current to potentially power small robots or drive chemical rea… Continue reading Two-faced carbon nanotube particles generate electricity in MIT device
California is set to be home to two new compressed-air energy storage facilities – each claiming the crown for the world’s largest non-hydro energy storage system. Developed by Hydrostor, the facilities will have an output of 500 MW and be capable of s… Continue reading World’s largest compressed air grid “batteries” will store up to 10GWh
Concrete is pretty useful, which is why it’s the most widely used construction material in the world. But it could be argued that it doesn’t really do anything. Now, engineers have made concrete that can conduct electricity and produce heat, by mixing … Continue reading Dash of nanocarbon black makes conductive, heat-generating concrete
Last month, large parts of the southern United States experienced their coldest temperatures since the 1899 Blizzard. Some of us set new all-time lows, and I was right in the …read more Continue reading Ask Hackaday: How Do You Prepare?
There are energy sources all over the place, if you know where to look. Researchers at the Chinese University of Hong Kong (CUHK) have now designed new modular nanogenerators that can harvest energy from a variety of different types of motion, such as … Continue reading Water-filled nanogenerators harvest energy from just about any movement
It’s a luxury to be able to access a modern machine shop, complete with its array of lathes, mills, and presses. These tools are expensive though, and take up a lot of space, so if you want to be able to machine hard or thick metals without an incredible amount …read more
Lightning strikes are a major trigger for wildfires, including the record-breaking blazes that devastated Australia, California and other regions this year. An international research team has now demonstrated a method that could effectively control whe… Continue reading Graphene tractor beams could one day redirect lightning strikes
