How A Colorado Startup Could Change The Game For Electric Cars

“What our technology does is it improves range and lowers vehicle cost,” Campbell said. “It’s as simple as that.”

As the name of his company suggests, Campbell thinks the key is a more-solid electric car battery. The lithium-ion batteries powering almost all of today’s electric vehicles rely on a liquid electrolyte, which ferries charged ions from a cathode to an anode. While the technology makes it practical to charge and recharge, the liquid can catch fire if overloaded.

For decades, scientists have seen a potential answer in solid electrolytes, which could allow a battery to soak up more energy without overheating.

New Material Can Store Energy From The Sun For Months or Even Years

If we’re going to get better at powering the planet with renewable energy, we need to get better at finding ways of efficiently storing that energy until it’s needed – and scientists have identified a particular material that could give us exactly that.

The material is known as a metal-organic framework (MOF), in which carbon-based molecules form structures by linking metal ions. Crucially, MOFs are porous, so they can form composite materials with other small molecules.

That’s what the team did here, adding molecules of the light-absorbing compound azobenzene. The finished composite material was able to store energy from ultraviolet light for at least four months at room temperature before releasing it again – a big improvement over the days or weeks that most light-responsive materials can manage.

This Massive New Vertical Farm Can Produce 1,000 Tons of Produce a Year

Once running at full capacity by the end of next year, its creators say, the facility will be able to generate a ton of food. Produce can be harvested up to 15 times a year without needing any soil or daylight.

Automated robots will be used to both plant seeds and check in on them later as well.

Nordic Harvest envisions that other massive facilities like it could have a major impact on the global fresh food supply. In fact, vertical farms covering an area of 20 soccer fields could grow enough greens for the entirety of Denmark, the startup argues, as reported by Fast Company.

Farmer fish become first animal found domesticating another species

Human civilization wouldn’t be where it is today if we hadn’t domesticated animals to be either loyal and cuddly or dumb and tasty. Now, researchers in Australia have discovered what they claim is the very first example of an animal domesticating another animal – a fish species found to recruit tiny shrimp to help tend their algae farms.

It’s believed that humans first domesticated the wolf around 15,000 years ago to help us hunt, and later for companionship. Over the following millennia, we added goats, pigs, sheep and cattle for food and materials. And almost every plant we eat looks nothing like their original wild counterparts, having been honed for thousands of years at our hands to be bigger, hardier, tastier, more nutritious or easier to grow, harvest and eat.

So far, the only other organisms known to domesticate others have been insects – for example ants farm aphids, protecting them from predators in exchange for the sweet sticky goo they excrete. But the behavior has never been observed in other vertebrate species before.
