You've likely heard of solar energy, but what is osmotic energy?
- Osmotic power plants harvest energy from the difference in pressure or salinity between salt and freshwater using a semi-permeable membrane.
- One of the major challenges for this kind of renewable energy, however, has been developing effective and durable membranes.
- Now, new research demonstrates a durable and effective membrane that could significantly improve osmotic energy collection.
Fashion Week, 2050
- The clothing of the future will look nothing like what we wear today. Or maybe it will.
- A hunger for sustainability is leading researchers to new organic materials from which to design clothing.
- Other visionaries are working to make our future outfits as smart as we want to look.
Researchers from UCLA invent a device that generates electricity from a rather unusual source.
- UCLA scientists have invented a cheap, flexible, and simple device called snow-TENG that generates electricity when it comes into contact with snow.
- Scientists have known that snow carries an electrical charge for several decades, but this device is one of the first to capitalize on that effect.
- The researchers believe that snow-TENG could be used in movement-tracking applications or as a simple weather station that requires no battery to operate.
Not every part of a satellite burns up in reentry. Considering the growing number of satellites in orbital space, that's a big problem.
- Earth's orbital space is getting more crowded by the day.
- The more satellites and space junk we put into orbit, the greater a risk that there could be a collision.
- Not all materials burn up during reentry; that's why scientists need to stress test satellite parts to ensure that they won't become deadly falling objects.
A parlor-trick mystery explained at last.
- Two grape halves heated in a microwave produce light-emitting ionized gas, or plasma.
- The grapes collect and trap microwaves whose energy eventually bursts outward.
- The discovery could lead to passive microwave antennas.
