Thermoelectric generator contrasts heat of Sun and cold of space

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

Two-faced carbon nanotube particles generate electricity in MIT device

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

World’s largest compressed air grid “batteries” will store up to 10GWh

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

Dash of nanocarbon black makes conductive, heat-generating concrete

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

Water-filled nanogenerators harvest energy from just about any movement

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

Machining Without Machines

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

Graphene tractor beams could one day redirect lightning strikes

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

“Fifth state of matter” used to make new type of superconductor

Superconductors – materials in which electricity flows without any resistance whatsoever – could be extremely useful for future electronics. Now, engineers at the University of Tokyo have managed to create a superconductor out of a state of matter call… Continue reading “Fifth state of matter” used to make new type of superconductor
