Hydrogen is a clean fuel source, and using sunlight and water is the cleanest way to produce it. Now, engineers from Columbia University have developed a “solar fuels rig” that floats on the ocean, captures energy through a solar cell and uses it to harvest hydrogen from the water beneath it.
Newfangled fabrics can harvest energy with your every move.
Using principles similar to those deployed in large hydroelectric power plants, a team of Chinese researchers has developed a tiny nanogenerator that can potentially sit inside a vein and generate electricity from blood rushing through it.
We’re used to receiving data wirelessly, and wireless power is also starting to make its way into devices. Now, researchers from North Carolina State University (NCSU) have developed a system that can combine the two, wirelessly transmitting both data and power simultaneously from a distance.
ARCA Space Corporation has announced its linear aerospike engine is ready to start ground tests. Designed to power the world’s first operational Single-Stage-To-Orbit (SSTO) satellite launcher, the engine took only 60 days to complete from when fabrication began.
The new cooling system, which uses no electricity, could make future air conditioning and refrigeration cheaper by sending heat up into space.
Carbon dioxide–splitting techniques could store excess electricity from renewable sources
Nanotube weave can light up an LED when pulled
The green-tech guru is backing an energy storage breakthrough that could power the future.
Today’s soldiers need to carry pounds of electronic equipment, and that much again in batteries to power it all. Now a chance discovery might help lighten the load. The US Army Research Laboratory has created an aluminum-based powder that produces a high amount of energy when placed in water.
