Hexocover Solar Technology for Water Conservation

Looking to solve the evaporation of water from bodies of water, such as mining tailings, reservoirs and ponds, a new technology, called Hexocover, was invented at the University of Arizona. Simultaneously generating energy reserves with the use of solar panels, the invention consists of hexagonal-shaped modular floating cover panels that are made from UV inhibited recyclable plastic and arranged to fit individual water surface dimensions and form a cover over the water.

Commenting on the purpose of the technology, the university’s renewable energy network director, Ardeth Barnhart, said “Mining activity typically requires a lot of energy. This technology is a great example of how original ideas that develop the use of solar energy to transform industrial processes can have immediate and transformative effects on water and energy use, create positive environmental impact and provide direct benefits to our economy.”

The Hexocover was developed by Moe Momayez from the university’s Department of Mining and Geological Engineering and Nathan Barba from RePower Design as a result of their effort to find a solution to water conservation in mining tailings and ponds. Their project was commended by “Mining Global”, who wrote that this technology has untapped potential for the industry, stating, “The new technology will offer a combination of positive environmental impact by minimizing water evaporation, which is costly for mining companies to replace, as well as generating electricity.”

This invention was also realized with the help of Tech Launch Arizona, which worked with Barba’s company and executed an exclusive license for it that granted RePower Design the sole right for the commercialization of the technology, which includes the solar panel integration and the floating panel design.

The inspiration came from the fact that Tucson has an evaporation rate of 109 inches per year and its constant need to replenish water in its reservoirs and storage facilities. Also, Momayez has been investigating the integration of PV panel deployment in reclamation and mining processes, the effects of mining on PV output efficiency and the geotechnical considerations related to installing these panels on tailing slopes.

“We needed a way to prevent the evaporation of (tailing pond) water, but we needed a system that could move out of the way when the tailings are being released into the ponds,” stated Barba. “If we can cover them, we can help with the devastating water shortage problem here in the southwestern U.S. and around the world. For someone who owns water reservoir, like a mine or municipality, this invention provides a dual benefit and a dual revenue stream.

As for Momayez, he stated, “The PV work on reclaimed mining lands has gained national recognition and the idea to control the evaporation of the supernatant water accumulating in the middle of tailing storage facilities was a natural extension of my research and a huge step forward to save water in arid climates worldwide.”

According to research, the mining industry has been historically slow to adopt renewable energy technology. However, it forecasts that renewable energy technologies will supply between 5 and 8% of the mining industry’s power consumption by 2022 throughout the world. In addition, these technologies, particularly the Hexocover, would minimize the overall impact of mining on the environment.

Batteriser Product Review

Batteriser Product Review

The Batteriser is the first micro-thin, stainless steel sleeve that extends by up to 8 times a battery’s life, just by slipping the product into it. The key here is that most devices only tap a fraction of the energy a battery has, and the Batteriser taps into the remaining energy that is, usually, thrown away. This new product comes in AA, AAA, C and D variations, and with its micro-thin design, it will just slip over a battery and fit it neatly back into a device’s battery compartment.

 

Using the Batteriser

The Batteriser can revive a battery instantly in 3 simple steps: grabbing the battery; slipping the sleeve on; and putting it into the device. In fact, this product is incredibly user-friendly and simple to use—after slipping the battery into the sleeve, the sleeve can just be left on the battery while it is being used to its fullest. Once it is completely dead, keep the Batteriser, discard the battery and then repeat the process for the next battery to be used.

 

Overall Features:

  • It is reusable—over and over and so on…
  • It fits into most devices.
  • It saves you money on battery purchases.
  • It taps instant energy and does not need charging time.
  • It contains no harmful chemicals and is safe for air travel.

 

Technology Used

The Batteriser is considered as an intelligent voltage management and delivery mechanism device, which is made of thin stainless steel that slips over almost any type of battery and fits neatly back into a device’s battery compartment. With a significant number of batteries thrown away that still have a lot of energy left in them, they would be a valuable waste. This new product uses proprietary circuitry to maintain an optimal output voltage, allowing the end device to access untapped energy in batteries and making them last longer.

 

Performance Efficiency

Every time the Batteriser is used and reused, the user will be able to save more money. With it, they can make a dramatic difference on their new and most used batteries.

This new product tends to have a more dramatic effect with high-drain devices, but the most enjoyable perk would be the huge battery life that is increased with it. As previously mentioned, it helps the user to save more money by reducing the number of batteries needed to be purchased. And as long as it is taken care of, it is re-usable. Take note that the amount of money saved with the Batteriser depends on how much batteries cost, and how effective this new product is with the device.

 

Environmental Impact

The Batteriser saves the environment by reducing number of perceived dead batteries that are thrown away, which are estimated to be about 15 million in volume, ending up in landfills every year, creating a significant carbon footprint. Greenhouse gas emissions from factory production and sourcing raw materials, along with the transportation of batteries around the world, result in potentially hazardous implications for the planet.

The solution is simple—we consume less batteries with the Batteriser, and the world would be better!

The 9V Batteriser is scheduled to be available next year.

Can Hydrogen Fuel the Future?

Can Hydrogen Fuel the Future?

By Guest Blogger Philip Piletic

There has been a lot of public debate about the use of hydrogen to replace fossil fuels as the main source of energy. Some of the arguments in favor of spending more money on researching the use of hydrogen are that it is plentiful, sustainable and generates only water vapor that doesn’t contribute to pollution or global warming. While most people believe that developing clean energy sources is essential, until recently, hydrogen lagged behind in the race towards energy independence.

Size, weight, safety concerns and cost were considerations that prevented mass production of hydrogen fuel cells that produce electricity by converting hydrogen and oxygen into water. Part of the cost is attributed to creating the infrastructure necessary for large scale utilization. Currently, in the U.S., California has most of the 10 existing hydrogen filling stations. but has passed legislation to increase that number to 100 stations by the year 2024. London has only 2, compared to 1200 charging stations for electric cars.

One argument against the switch to hydrogen is that currently, two of the most common processes for isolating hydrogen, hydrogen pinch and steam reforming, rely on fossil fuels, including methane, to generate heat. Bio hydrogen production and thermolysis are other methods. Currently, the cleanest method of production is electrolysis.

In the process of electrolysis, water is split into oxygen and hydrogen using an electric current, with oxygen being produced on a positively charged electrode, and hydrogen on a negatively charged one. The two gases are prevented from reacting with each other by a membrane between the cathode and the anode. The hydrogen can then be compressed as a gas or in liquid form to be stored or transported for use. Currently, only about 5 percent of hydrogen is produced by clean electrolysis. However, both public and private research promise rapid advances in the clean production of hydrogen.

In addition to fuel cells used to power automotive vehicles, hydrogen has a number of other uses. Hydrogen gas can be used to reduce metal ore. Chemical industries use hydrogen to produce hydrochloric acid, ammonia, and methanol. The process of atomic hydrogen welding utilizes hydrogen gas. Ironically, processing fossil fuel also relies on hydrogen. Hydrogen is also the hydrogenating agent used to saturate oils and fats, making them healthier for consumption. Hydrogen fuel cells are used in submarines and weather stations. Hydrogen, in liquid form, is used as rocket fuel for space exploration.

One of the safety concerns being addressed is that of avoiding corrosion when mixing hydrogen with other liquid elements. This is especially important due to the fact that hydrogen is a highly explosive substance. Temperatures in processes utilizing hydrogen with other liquids, such as refining oil, must be strictly controlled because sealants are manufactured according to specific temperature guidelines and special valves are used in the process. Lessening dependence on oil and other fossil fuels such as coal has become an increasingly viable option for reducing our carbon footprint.

According to NPPD board member Mary Harding, said that switching from coal to hydrogen, even at one power plant, will “…keep more than a million tons of carbon out of the atmosphere.” That amount is equal to approximately 10 percent of the Nebraska Public Power District’s total carbon emissions each year. More power plants switching from coal to hydrogen, combined with a greater number of automobiles powered by hydrogen fuel cells, will make a huge difference in preserving our natural resources, including the air we breathe.

It has been estimated that hydrogen power obtained from renewable raw materials can reduce our carbon footprint by a full 70 percent compared to conventional gasoline powered cars. Vehicles powered with hydrogen fuel cells have a range of approximately 500 kilometers, compared to 200 kilometers offered by an electric battery. An additional advantage is that charging a hydrogen fuel cell takes just four minutes.

According to Rutgers University chemist Tewodros Asefa, “Hydrogen has long been expected to play a vital role in our future energy landscapes by mitigating, if not completely eliminating, our reliance on fossil fuels” Towards that worthy goal, researchers are continuing to create new technologies, such as carbon nanotube technology to make the vision of clean energy for manufacturing and mobility a reality.

Green Car Technology Means Fuel Savings

Guest Post by Trisha Miller

Automobiles are constantly being upgraded with the latest tech, this is no secret. However, a few green car technologies have emerged in the public eye as of late that could make a huge impact on lowering things like emissions and gas consumption. There have also been huge advances in already existing car technologies. Let’s explore a couple possibilities in the future of vehicular travel.

 

Self Driving Cars

Self driving cars could be commonplace within the next 5 years or so .These cars will allow passengers to input the destination and installed computer on board will know the most effective route. It is likely that these cars will be used to carpool eventually so there aren’t as many single cars on the road causing unnecessary traffic and emissions. It is also probable that automated cars will also be electric to save companies on gas expenses. Without a driver, cars would also not need to waste as much product into the car itself. The entire design of a car has the possibility to be reinvented in order to use only the structural resources that are necessary.

Companies like Tesla, Uber, and Google are pouring money into the future of driving. The Uber company has commented with their stance on automated cars, “As a global leader in urban transportation, we have the unique opportunity to invest in leading edge technologies to enable the safe and efficient movement of people and things at giant scale.”

According to The New York Times eco-friendliness is not the only reason to pursue self-driving cars, they also have economy friendliness in mind. States across the US are hoping to recruit carmakers that will invest in automated vehicles. This produces an opportunity to open up more jobs and provide and an additional annual tax revenue. As such, states like Florida and California have passed laws regarding the ease of testing these cars on fake cities. However, years of still testing lay ahead before automated cars take over transporting people and our goods across the country.

 

GPS Fleet Tracking

Business owners now can now track the status on all company cars. Some businesses are installing GPS tracking devices inside their employees vehicles in order to keep track of delivery times and transport efficiency. The truly amazing part is that it doesn’t even come close to ending there. These advanced GPS devices can also navigate the driver through the most efficient routes, monitor the speed of the vehicle, how many stops the car makes, when the car last had a tune up, and gas levels of the vehicle.

Companies are beginning to design “end-all-be-all” GPS technology that includes all of these features brought together into one system. One such company called GPS Trackit highlights ways that a company can save costs on fuel including reducing idling time, dispatching the closest drivers, and preventing speeding.

Employers will now hold the power of knowledge in right at their fingertips. Companies can now make quick changes in order to save large amounts of money on time and fuel wasters that were never able to be monitored in the past – all from the convenience of smartphones.

 

Taxi Selection Apps

Speaking of smartphones, some tech companies have created a system that now lets the passenger choose which car they want to ride in. An example of a company that uses this feature is Addison Lee based in the UK. This app allows a single person to go with a much smaller or electric car instead of a large one that may use more fuel or the reverse is also available of course, for those who have large parties.

Other companies, like Kabbee, compare companies and features so that the consumer can choose from a variety of cars to suit their own needs. This app even provides options such as cars available with child seats and compares all prices in the vicinity to encourage the user to choose the most economic cab service.

Smaller steps such as apps all the way to automated cars are all hugely headed in the right direction. With cars being a huge fuel and resource waster any technology that can diminish this footprint could be the next big thing in the automotive and eco world.

What types of eco-changes do you support in your daily commute?
