Comments Off on This DIY algae kit is an easy science experiment for kids

BioBombola is a DIY algae kit specially designed to teach kids how to grow their own domestic garden of spirulina – a sustainable source of plant-based proteins. The project is the brainchild of ecoLogicStudio’s Claudia Pasquero and Marco Poletto, who wanted to create a fun and educational way to keep their children occupied during the shutdown in London. In addition to cultivating the nutritious blue-green algae, the kit also helps to absorb the same amount of carbon dioxide as two young trees and provides the home with the same amount of oxygen as seven common indoor plants. Perhaps best of all, BioBombola allows children and adults alike to interact with nature from the comfort of their own homes. Related: Eos Bioreactor uses AI and algae to combat climate change The two researchers got the idea after creating an algae-growing and air pollution data collection project with their children, who were already participating in a home-school program. After their experiment has finished, the idea for the mini algae harvesting kit was born. Each kit comes with a nutrients bag, a 15-liter starting batch of living photosynthetic spirulina cells, an air piping system, a pump to keep the medium afloat, a customized photobioreactor and a 1-meter-tall, lab-grade glass container. Not only does the bubbling of the small air pump keep the precious algae constantly stirred and oxygenated, it also creates a soft, calming sound similar to a fish tank. The fresh, cultivated spirulina can be harvested several times a week and collects up to 7 grams of product per day (the daily recommended supplement intake for a family of four, according to the inventors) to be used in food and drinks. The harvesting process is simple and suitable for children, as well. While it is recommended to install the kit in a sunny spot or near a grow lamp, the photobioreactor can adapt to almost any environment. + EcoLogicStudio Photography by NAARO via EcoLogicStudio

Applying rock dust to farms could boost carbon sequestration

Comments Off on Applying rock dust to farms could boost carbon sequestration

A report in the journal Nature has revealed that enhanced rock weathering (ERW) could help slow climate change by sucking carbon dioxide from the atmosphere. This process involves spreading rock dust on farmland to help absorb atmospheric carbon dioxide. When rocks, such as basalt and other silicates, are crushed and added to the soil, they dissolve and react with carbon dioxide, forming carbonates and lock carbon dioxide. Although this is the first time that scientists are proposing this approach in dealing with carbon dioxide, it is not a new concept. Normally, farmers use limestone dust on the soil to reduce acidification. The use of limestone in agriculture helps enhance yield. If the proposed enhanced rock weathering technique is adopted, farmers could incorporate other types of rock dust on their land. Related: Eos Bioreactor uses AI and algae to combat climate change According to the study, this approach could help capture up to 2 billion metric tons of CO2 each year. This is equal to the combined emissions of Germany and Japan. Interestingly, this technique is much cheaper than conventional methods of carbon capturing. The scientists behind the study say that the cost of capturing a ton of CO2 could be as low as $55 in countries such as India, China, Mexico, Indonesia and Brazil. For the U.S., Canada and Europe, the cost of capturing one metric ton of CO2 with ERW would be about $160. The scientists propose using basalt as the optimal rock for ERW. Given that basalt is already produced in most mines as a byproduct, adding it to farmland soils can easily be instituted. Further, the countries that contribute the highest amounts of carbon dioxide are the best candidates for the ERW technique. Countries such as China, India and the U.S. have large farmlands that can be used to capture excess CO2 from the atmosphere. Given that carbon emissions are a big problem for the entire world, this technique might just be the light at the end of the tunnel. The enhanced rock weathering technique is affordable and practical, making it a win-win. + Nature Via The Guardian Image via Pixabay

Comments Off on Rocket Crafters creates safer, greener hybrid rocket engine technology

Rocket Crafters, an aerospace company based in Florida, is patenting its hybrid rocket engine technology . The engine, which the company described as throttle-able, affordable, reliable and 3D-printed, is said to be a milestone in the world of rocket science. For many years, rocket scientists have been trying to develop a hybrid engine — unsuccessfully. All of these attempts failed along the way due to fuel combustion issues. However, thanks to 3D-printing technology, Rocket Crafters has managed to develop a hybrid engine known as the STAR-3D. The engine has completed over 40 subscale engine tests and is now poised to engage in large-scale tests. What is a hybrid rocket engine? If you are not a fan of rockets or rocket science, you may not have a clue about the impact of developing a hybrid engine . In simple terms, a hybrid engine means that the rocket will be fueled by a combination of solid and liquid or gas fuel. This is a big achievement for the world, considering that the hybrid engine will be much greener. The combustion of rocket fuels has negative impacts on the environment, but this new technology tries to address these issues. Related: Studio Roosegaarde’s laser light art tracks floating space waste in the sky Rockets that are strictly solid-fueled cannot be throttled or restarted, while hybrid rockets can. This is one of the reasons why many scientists have been working on hybrid rocket technology. The hybrid engine is much faster and safer as compared to solid- or liquid-fueled counterparts. According to Rocket Crafters, the company can also scale rocket engines from 125lbf all the way to 5000lbf. Compared to the liquid-fueled rocket engines, the hybrid is much easier to develop and less expensive, too. Liquid-fueled rockets have been favored in the past for being environmentally safer than solid-fueled rockets; however, the cost of developing liquid-fueled rockets has proved to be the problem. Most aerospace companies have been striving to find a balance between the cost and sustainability of the rockets . Hybrid engines are less expensive in terms of maintenance. The engines by Rocket Crafters only have two movable parts, which means that they are less mechanical. They separately store fuel in two different states (solid and liquid), which helps safeguard against accidental detonation. But the attempt to shift to hybrid engines has been met by many challenges. According to a report in 3DPrint, both governments and industries have been unable to develop a safe hybrid engine for years. In previous attempts, the rockets were met with issues such as excessive thrust and unpredictable vibrations. Purpose of the hybrid engine In the initial stages of developing the engine, it was used to send small rockets into the Earth’s orbit. The company now plans to work with private businesses and governments that send small satellites to outer space. The 3D-printed hybrid engine makes launching rockets into space much easier and safer. Just as many other companies that have been using 3D-printing to make the world a better place, Rocket Crafters have managed to change the future of rockets completely. This means that rocket travel will be much more accessible. The new technology now seeks to bring the cost of more sustainable rocketing to a record low. Hybrid engines are greener The most impressive aspect of the new hybrid engines is that they are better for the environment. Traditionally, solid-fueled engines would emit heavy carbon waste into the atmosphere . Due to such effects of solid-fueled engines, there has been pressure for more rocket manufacturers to turn to liquid-fueled engines, which are greener. Liquid-fueled engines are propelled by liquid hydrogen, which produces water vapor exhaust. But the production of hydrogen itself can also cause significant pollution. The end game for rocket manufactures turns out to be hybrid engines — something that Rocket Crafters hopes to make as safe and sustainable as possible. + Rocket Crafters Image via Unsplash

Comments Off on Eos Bioreactor uses AI and algae to combat climate change

A new artificial intelligence invention by Hypergiant Industries could prove to be the solution to the world’s carbon dioxide problem. The company is launching the second generation Eos Bioreactor, currently still a prototype, that can be used to absorb excess carbon dioxide from the atmosphere and give out oxygen. Besides its ability to reduce environmental pollution, the new AI-based bioreactor also improves health. The excessive presence of carbon dioxide in the atmosphere has led to a steady rise in the average global temperatures over the years. A National Geographic report states that ocean levels will rise by up to 2.3 feet by 2050 due to melting glaciers. This is just one of many problems that are brought about by excessive carbon dioxide in the atmosphere. Terrestrial radiation, which is supposed to be absorbed by the ozone layer, is also retained in the atmosphere. This leads to the greenhouse effect, where the globe is overheated. Related: New map exposes secrets of Antarctica’s green snow The Eos Bioreactor seeks to reduce the level of carbon dioxide in the atmosphere to address climate change. Traditionally, the world relies on forests to absorb excess carbon dioxide in the atmosphere and produce more oxygen. However, deforestation in major forests across the world has greatly affected the effectiveness of this approach. For instance, deforestation of Amazon increased by 34% in 2019. Such challenges make it unrealistic for the world to continue relying solely on forests to combat climate change. Technology like the Eos Bioreactor could help address these issues. According to the manufacturer, the AI-based technology is more effective because each boosted algae bioreactor is 400 times faster in capturing carbon dioxide than trees in the same unit area. Simply put, a single 3-foot by 3-foot bioreactor can absorb the equivalence of the carbon dioxide captured by an acre of forested land. Besides absorbing carbon dioxide, the bioreactor also monitors airflow, bio-density, pH, type of light and harvest cycles. Because it can be used in a home or office setting, the Eos Bioreactor can completely monitor and purify the quality of the air you breath. Why use the Eos Bioreactor According to the CDC, climate change has an effect on human health . Climate change disrupts the quality of natural air, resulting in respiratory and cardiovascular complications. Extreme weather changes can lead to serious cardiovascular injuries and even death. The effects of climate change can also contribute to stress in food production and lead to malnutrition. According to Hypergiant Industries, Eos Bioreactor technology can help reduce such effects. How the Eos Bioreactor works Algae require high levels of carbon dioxide to thrive. The bioreactor provides the right environment to grow algae, which can consume most of the carbon dioxide in the atmosphere. However, the system is much more complex than that. Besides exposing algae to the atmosphere for carbon dioxide absorption, the system uses artificial intelligence to control the lighting, airflow, temperature and other factors of the environment. Such factors facilitate the accelerated rate of carbon dioxide absorption and processing. The bioreactor works in 5 key processes: Air intake: The air intake absorbs open air in a room or can be connected to a building exhaust. Once absorbed, the air is bubbled into the bioreactor tank, where it combines with algae. Growing algae : For the algae to grow, it needs carbon dioxide and light. Once carbon dioxide has been pumped into the bioreactor tank, the algae have to be exposed to light. The algae and water are pumped through tubes to maximize exposure to light. They mix with carbon dioxide in the bioreactor tank for the process to commence. Biomass accretion : Once the algae and carbon dioxide are mixed, the algae consume carbon dioxide to produce biomass. The biomass is harvested to create fuel, oils and high-protein foods and fertilizer. Harvesting and separation: The Eos Bioreactor uses AI to control the harvesting process. The harvesting system allows the reactor to retain the maximum amount of algae to suck up carbon dioxide. Clean air exhaust: Once the system uses carbon dioxide to produce biomass, it also consumes all the impurities in the air. As a result, 60% to 90% of the carbon dioxide input is consumed. The resulting oxygen-rich, clean air is released to the environment. The shape and appearance of the bioreactor The Eos Bioreactor measures 3-feet-by-3-feet-by-7-feet and is designed to fit in small spaces, including offices and homes. The bioreactor has options for solar power connections, which will make it usable in remote regions. The power used in running the system is minimal, and the waste produced can be utilized for other purposes. About Hypergiant Industries Hypergiant Industries is a company that focuses on providing solutions to current humanitarian challenges. One of the biggest challenges that humans face today is climate change. The development of the AI-powered bioreactor is one of many projects spearheaded by the company. Hypergiant Industries is working on several environment-focused products and solutions for clients including governments and Fortune 500. + Hypergiant Industries Images via Hypergiant Industries

Atmospheric carbon dioxide at highest level in 3 million years

Comments Off on Atmospheric carbon dioxide at highest level in 3 million years

Carbon dioxide levels in the atmosphere are now at the highest level they’ve been since the Pilocene Era, 3 million years ago, when giant camels roamed arid land above the Arctic Circle. According to a new National Oceanic and Atmospheric Administration ( NOAA ) report, in 2018, the global average carbon dioxide amount reached a record high of 407.4 parts per million (ppm). NOAA points a finger directly at humans, noting that the atmospheric carbon dioxide has increased about 100 times faster annually over the past 60 years than from previous natural increases. “Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy,” the report said. “Fossil fuels like coal and oil contain carbon that plants pulled out of the atmosphere through photosynthesis over the span of many millions of years; we are returning that carbon to the atmosphere in just a few hundred years.” Related: Pacific Ocean’s elevated acidity is dissolving Dungeness crabs’ shells Globally, atmospheric carbon dioxide increased about 0.6 ppm per year in the 1960s. In the last 10 years, this figure has been about 2.3 ppm per year, the study said. Carbon dioxide absorbs and radiates heat more than other major atmospheric components, such as oxygen or nitrogen. The NOAA report likens greenhouse gases to bricks in a fireplace that continue to release heat after the fire goes out. This warming effect is necessary to keep Earth’s temperature above freezing — up to a point. But once the level gets out of balance, these greenhouse gas “bricks” trap too much heat and make the Earth’s average temperature continue to rise. Carbon dioxide also dissolves into the oceans , where it reacts with water molecules to produce carbonic acid and lower pH levels. Since the Industrial Revolution began in the late 18th century, the ocean’s pH has dropped significantly, interfering with marine animals’ ability to fortify their shells and skeletons by extracting calcium from the water. “For millions of years, we haven’t had an atmosphere with a chemical composition as it is right now,” Martin Siegert, co-director of the Grantham Institute at Imperial College London, told NBC News . “We’ve done in a little more than 50 years what the Earth naturally took 10,000 years to do.” + NOAA Via EcoWatch and NBC News Image via Marcin Jozwiak
