Bioreactors
"While most antipollution technologies involve massive, complex equipment, some scientists are experimenting with tiny, simple living organisms called cyanobacteria that eat polluting carbon dioxide (CO2). These algae can flourish in the blistering temperatures of chimneys. Researchers have designed "bioreactors," window-screen-like membranes teeming with cyanobacteria, for future installation into power plant smokestacks. Fiber- optic cables would focus life-sustaining light across the membranes, allowing the algae to grow inside chimneys while feasting on a diet of CO2 exhaust. This technology has already proved itself in small-scale demonstrations. A test on a fully operational power plant is about five years away, and scientists are also studying the same algae as a potential source of hydrogen energy." (NOVA)
What else can I help you with?
What is being done about Thermal Pollution?
One thing that being done about thermal pollution is that less electricity is being used. Another thing is that heated water is being reused and stored to reduce thermal pollution.
Why would not driving help reduce air pollution?
Not driving helps reduce air pollution because fewer vehicles on the road means less emissions being released into the atmosphere from exhaust fumes. This can lower the levels of pollutants such as carbon dioxide, nitrogen oxides, and particulate matter, which can contribute to smog, respiratory issues, and climate change.
How might the presence or absence of cyanobacteria be used as an index of pollution in lakes?
The presence of cyanobacteria in high concentrations in lakes can indicate pollution due to excess nutrients, such as nitrogen and phosphorus, from sources like agricultural runoff or untreated sewage. Cyanobacteria thrive in nutrient-rich environments and can form harmful algal blooms, producing toxins that can be detrimental to aquatic ecosystems and human health. Absence of cyanobacteria in lakes may suggest a healthier, less polluted aquatic environment with balanced nutrient levels.
Is Examining the water and pollution levels a sentence?
Yes, "Examining the water and pollution levels" is a grammatically correct sentence fragment. It lacks a subject and a verb that would make it a complete sentence, but it conveys a clear idea about the action being taken regarding water and pollution. To make it a complete sentence, you could say, "We are examining the water and pollution levels."
What is been or is being done to reduce the pollution that causes smog and acid rain?
You cannot use CFC's anymore
What has been or is being done to reduce the pollution that causes smog and acid rain?
You cannot use CFC's anymore
What are the remedial measures of sound pollution?
Remedial measures of sound pollution are the steps we take to reduce excess noise. This can be as simple as being aware of how loud we speak or listen to music.
Why does Philadelphia cause so much pollution?
Philadelphia experiences high levels of pollution due to factors such as traffic congestion, industrial emissions, and a high concentration of older buildings that may not be energy-efficient. Additionally, the city's proximity to other major urban areas and industrial hubs contributes to its pollution levels. Efforts are being made to improve air quality and reduce pollution through initiatives promoting clean energy and sustainable practices.
What are examples of non pollution indicators?
Examples of non-pollution indicators include biodiversity levels, air quality, water quality, and the presence of natural habitats. These indicators reflect the overall health and well-being of ecosystems without being directly impacted by pollution.
How can we conserve sound energy?
To conserve sound energy, you can consider using sound-absorbing materials in rooms to reduce noise levels, using headphones instead of speakers for personal audio, and maintaining equipment to prevent unnecessary noise pollution. Additionally, being mindful of noise levels and adjusting volume settings can help conserve sound energy.
How do you stop sound polltion?
You can reduce sound pollution by using sound-absorbing materials like rugs or curtains, installing soundproofing barriers, being mindful of noise levels in residential areas, utilizing noise-canceling technology, and advocating for stricter noise regulations in public spaces.
What would happen if you don't reduce?
If you don't reduce waste, resource consumption, and pollution, environmental degradation will worsen, leading to negative impacts on ecosystems and biodiversity. This can result in increased climate change effects, such as extreme weather events and rising sea levels. Additionally, human health can be compromised due to pollution and the depletion of natural resources, ultimately affecting quality of life and economic stability. Addressing reduction is crucial for sustainable development and the well-being of future generations.
