Transcript of How can technology affect climate change?

Climate change is a growing issue in modern life, many scientists and citizens try to aid this problem using countless methods. Technology, being a growing source of innovation, has been one of the leading methods in this struggle of man versus Earth. Here are some examples of technology that is contributing to this struggle.
Climate Change and Technology

In the late 60's, a japanese scientist discovered the properties of Titanium Dioxide. This Photo catalytic process was named the Honda-Fujishima effect. In 1994, a swedish lab was created to study this effect. This lab was a combination of three universities, who still strive today to make this effect useful in everyday life.
The process of artificial photosynthesis is sill very unstable, and has not been tested under urban circumstances. Some scientists think compounds that produce Hydrogen in a photo catalytic process can be used in artificial plants in offices and other buildings. While Titanium Dioxide still remains the most stable of these compounds, other materials are being discovered and tested every day.
At the rate of 2$ per gallon, extracting oil from algae can be an expensive process. Mixing the algae in a small amount of water and burning it, this fuel can be transformed into potent biofuel in less than an hour. This fuel is used in boats, jets, and other engine-powered machinery.
Using the process of algae oil and other biofuels is considerably less polluting than fossil fuels. Studies have shown that using this fuel in everyday life could reduce carbon footprints by almost 80%. This is a very significant innovation in eco-friendly technology, and scientists hope to improve the process.
Solar power has always been an Eco-Friendly option for electricity in many different countries. Most solar panels are composed of Crystalline Silicone and a light film of Cadmium Telluride. These compounds are expensive, but do not produce much waste. Solar windows are to be made from a similar material, but transparent.
This new technology breakthrough is planned to be used not only in cities, but in everyday homes. Solar powered windows are hoped to be available some time in the this quarter of 2014. Even though being costly, this could help modern citizens' electrical consumption and waste production.
Photosynthesis is vital for both flora and fauna on Earth. Trees, flowers, ferns, all plants have some kind of photosynthesis process. But this isn't the only reason we need plants. Every day, more and more of the world's vegetation is being used for building, medicine, and food. Scientists think this can be aided. Titanium Dioxide is a material that, when exposed to sunlight and water, produces amounts of Hydrogen and Oxygen. This could be used as an artificial photosynthesis.
Artificial Photosynthesis
In September 2013, researchers at the U.S. Department of Energy's Pacific Northwest National Laboratory discovered a way to make algae into crude bio diesel in 50 minutes or less. Algae is a very common occurrence in lakes and rivers, making it very easy to supply in large amounts. The Lipid in algae can be extracted and converted into oil, similarly to extraction of vegetable oil.
Solar power has been a staple of environmental technology for a long time, and new uses for this technique are being developed often and plentifully. One of these uses is a new integration method involving solar powered windows. These windows are planned to be used in office buildings, modern houses, and apartment complexes. Prototypes are being manufactured in the U.S.
