Washington University Researchers Explore Possibility of Converting Brick Walls into Batteries

Chemistry researchers at Washington University in St. Louis, Missouri explored the possibility of converting brick walls into a storage for electrical energy. The results of their experiment gave positive indications that brick walls can function like a batteries when attached to solar cells, while serving its decorative purpose. However, the researchers have yet to test whether the bricks can preserve their strength once the charged hematite components dissolve.

Assistant Chemistry Professor, Julio D’arcy and his colleagues at Washington University used regular red bricks commonly utilized in constructing houses. They then heated the bricks with acid vapor and applied a special conductive polymer called PEDOT (poly(3,4-ethylenedioxythiophene) polystyrene sulfonate), on brick materials to give the blocks the ability to store energy. However, since the bricks have been treated with acid, he does not recommend the as suitable materials for building construction purposes.

He added that they haven’t identified the material’s mechanical properties yet. Yet the point is that once they figure out a way to refine the method of converting bricks into batteries that are at the same time viable as building material, it is possible to have solar-powered brick walls that can be used for charging electronic devices.

Based on their experiment, a single piece of brick can hold more energy than an AA battery. Every three pieces of bricks, measuring 4 x 3 x 1 centimetre in size, can light up a green LEAD light for 10 minutes with only one charge. These battery bricks can be charged up to 10,000 times without losing more than ten percent (10%) of their storage capacity.

However, it is estimated that it would cost $2 to $3 dollars to produce a brick battery. That being the case, they still need to devise way on how to make the brick to battery conversion much cheaper, if to make it viable as a building material.

How the Researchers Converted the Bricks into Batteries

Professor D’arcy and his team first dissolved the hematite, which is the pigment mineral that gives the bricks their red color. The PEDOT chemical compounds were mixed in to make the dissolved hematite react, fully incorporating conductive PEDOT fibres into the dissolved hematite. Once the charged red minerals are applied as brick treatment, the red hematite color turns into a combination of dark brown and blue hues. To give the bricks a waterproof property, the bricks were coated with epoxy.

Tow Trucks Help Motorists Get Back On The Road – Tips To Improve Your Vehicles Fuel Efficiency

Vehicles play a crucial role in society, both in the public and private sectors. Primarily, they are used to efficiently move or transport people or goods from one place to another. However, no matter how reliable vehicles are, they can still breakdown. Thankfully, there are vehicles designed to carry other vehicles.

Tow Truck In San Jose – Helping Motorists Get Back On The Road

Tow trucks, for instance, are used to move or transport broken down vehicles. They could transport them to tow yards, auto repair shops or wherever the vehicle owner requests. For instance, Fast Tow Service tow truck in san jose provides 24/7 towing and recovery services in the San Jose Area.

They also do tire car lockout services, tire change, gas refueling, jumpstart, battery replacement, and other roadside assistance. With their professionally trained staff and quick response time, you’ll surely get back on the road in no time, making the the services they provide in the society essential and crucial.

Tips To Improve Fuel Efficiency

When it comes to fuel efficiency, car manufacturers are continuously developing their car models in order for them to be fuel and energy efficient. But as car owners, whether your vehicle is fuel efficient or not, there are things that you could do to save fuel.

Clean Out Your Trunk and Remove Unnecessary Weight

Vehicles get better mileage when it isn’t overloaded with unnecessary weight. Every 200lbs (90kgs) of added weight cuts off one-mile fuel efficiency. Most car owners accumulate unnecessary things in their vehicle trunks. So clean it out to eliminate unnecessary load.

Tires Should Have the Right Pressure

Purchase a tire gauge so you can check if your tires are inflated to the recommended tire pressure level specified by the manufacturer. A single underinflated tire could trim fuel efficiency by 2% per pound of pressure lower the correct inflation level. So keep your tires inflated to the proper pressure level.

Avoid Idling For Long Periods of Time

When a vehicle is idle, the worst mileage it could get is zero mpg. Idling for long consumes fuel that can be saved by basically switching off the car engine. Restarting the engine makes use of approximately the same quantity of fuel as you would when on idle for 30 seconds.
