You’re probably familiar with the concept of using a potato to power a lightbulb. What about a brick, though? We can’t say we’re ever thought about using something like this as a source of energy. However, it’s possible that they could eventually become the battery of the future.

A Reliable Source Of Energy

We have a variety of ways to produce electricity nowadays, from standard power outlets to things like wind power. However, these all have their downsides, with some only able to work correctly in the right conditions. That’s apparently less of an issue for bricks, though, according to Dr. Julio D’Arcy. The scientist believes that this material is capable of working as a reliable battery, and it’s all thanks to its coloring.

Chemistry At Work

Most bricks you encounter are rust-colored, and that’s because of hematite. This is a pigment that can apparently work as an electrode, and when combined with the porosity of bricks, it makes for an excellent source of energy. D’Arcy tested this by using vapors on the material, and the result was the formation of the polymer PEDOT. That, in turn, allowed the brick to become a supercapacitor capable of providing energy whenever needed.

Possibilities For The Future

D’Arcy apparently put his bricks through 10,000 cycles of being charged and discharged, and the outcome was definitely promising. The efficiency was as high as 90%, and it wasn’t impacted by moisture or temperature either. Given how cheap and easy bricks are to come by, that holds a lot of future energy potential. Apparently, the scientist believes that 50 bricks could provide as much as five hours of lighting if charged with solar energy. There’s just the slight downside that he’s only managed to light one LED for five minutes so far.

Although bricks might not be our primary source of electricity anytime soon, it’s good to know they could help us in the future.

Humans are not only the superior race in the world. The animal kingdom often beat the humans with their fabulous features. Speed is one of those striking components, which makes an animal frighteningly awesome! Here are the world’s fastest animals, who dominate land, water, and sky with their eye-blinking speeds and lightning-fast strides.

Fastest Animals on Land

• Cheetah

If there is an animal Olympics, cheetahs would dominate the sprinter races with their 60-70 mph or 96-112 km/h running speed. A cheetah named Sarah from the Cincinnati Zoo has the record of running the 100-meter sprint in just 5.95 seconds. Now, that is fast! The long slender body and powerful legs of a cheetah contribute to its lightning-speed stride.

• Ostrich

Though members of the bird family, ostriches roam on the ground. Being the largest birds on the earth, and the fastest birds on the ground, they can grow up to 9 feet or 2.7 meters and can cover 10-16 feet or 3-5 meters in a single stride, with a speed up to 43 mph or 70 km/h. These giant birds use their long powerful legs to gain quickness.

Fastest Creatures Under Water

• Sailfish

With a reported top speed of more than 68 mph or 110 km/h, sailfishes are considered the fastest fish in the ocean. But biologist Paolo Domenici doubts these figures and hence measures the speed of sailfish with his colleagues, to calculate the tail-beat frequencies, which is the fish equivalent of stride length. According to them, the speed of a sailfish is actually around 18-22 mph or 29-36 km/h.

• Dall’s Porpoise

According to Whale and Dolphin Conservation (WDC), Dall’s porpoise can speed through the water at up to 34 mph or 54 km/h. Biologist Paolo Domenici observes that Dall’s porpoises ride the bow waves, the wave created at a front of a sailing boat, to swim faster than normal. They have longer bodies and elongated mouths as contributing factors to their speed.

Fastest Animals in the Sky

• Golden Eagle

Golden eagles are North America’s largest birds, with wingspans reaching more than 7 feet across. They reach their top speed during aerial dives. When diving from great heights, these birds can zoom through the air at almost 200 mph or 322km/h speed.

• Peregrine Falcon

These are other predatory birds, which are the fastest animal in the world. When diving through the air, peregrine falcons can reach speeds of up to 220 mph or 354 km/h. Apart from this hunting speed, their regular cruising speed ranges between 40 and 60 mph or 64 and 97 km/h. A pair of pointed streamlined wings, drag-reducing stiff feathers, and a modified breastbone attached with powerful muscle help these special falcons to adapt that eye-blinking speed.
