Science is looking for solutions to the world energy crisis. Many different approaches are being considered. One approach, Lithium-Air Batteries Could Displace Gasoline in Future Cars.
For this project you should find some scientific work to ease the energy crunch, link to the article and then write a paragraph that summarizes the article. Paragraphs should be at least three well constructed sentences. You can look for research to actually provide alternate energy sources, reduce pollution, make vehicles more efficient, or any aspect where some advances are being made.
Next you should find one of the articles cited by one of your classmates for this project. You should then write a paragraph discussing the way both approaches are working toward a common goal.
If you are the first to enter an article, or you do not find particular interest in the other student articles, you may use the article cited above.

Make sure you put your ID and class section on your work. This project is due by midnight Sunday, 1/17. Remember that you need at least one project out of every two. If you do both projects one will count for extra credit.
If you have problems, email me at aphsbio at gmail.com. Make sure that you tell me what your problem was, and you can include your completed project.
solution
ReplyDeleteScientists might have figured out a easy and affordable way to solve the energy crisis. Nate Lewis a former scientist thinks he has figured out a solution. He sees cheap ways to convert solar energy directly into electricity. Then this can be used to convert water into fuel, like hydrogen, that can be turned back into electricity instantly. He says we need some sort of basic paint so electrons march into a utility line.
Li-air batteries are a good idea because they can store up to a gasoline lank of energy. They use a catalytic air cathode that supplies oxygen. The solar powered paint is a good idea because it is helpful to the earth in achieving our goal and it can be affordable.

Over the last couple of years scientists have been trying to find ways to create Lithium Air battery powered cars. These scientists also hope that eventually these new batteries will take over the old internal combustion engines currently cars. This will ultimately lower the amount of CO2 emissions and hopefully create a better environment for later generations to live in.

Recently Chevy unveiled its new plan to create a lithium ion battery powered car. This car will mostly run on electricity and the engine will only be used to crank the car's generator. What make this battery so easy and chap is that lithium is the lightest solid element which makes it portable and would weigh much less than the old nickel-metal-hydride batteries used for cars in the 1990s by GM. Chevy has not yet released a date or year when this car is expected to be sold to the public at the staring off price is around 40,000 dollars.

Part of out energy crisis problem has to do with our need for so much oil. There are now other options to use instead of oil that are not as bad for the Earth. One option to use is Grassolean which is a biofuel made from excess grease in pans. Another is to use heat from natural places like volcanoes to create power. A last option is to use nuclear power which recycles used fuel instead of just wasting more fuel.

The Li-air batteries are being thought of as a way to replace gasoline. These will be placed in cars instead of using gasoline to save the gas we have left. However the the technology for this idea is still not available and created. So even though this is a good idea, it may be awhile before it can actually happen.

Hydrogen
ReplyDeleteThis article explains how nanotechnology could help make hydrogen cars and more specifically, the way the fuel is made, more "green".Up to ninety percent of hydrogen production comes from fossil fuels like coal, gas, and oil. The rest is mostly made at nuclear power plants. This all means that even though the cars will give off nothing more than water and heat, we will still be dependent on fossil fuels to make the hydrogen.Nanotechnology and solar cells will make the process of developing truly clean hyrogen possible.
The article about the new Chevrolet Bolt and the use of lithium ion batteries in it goes hand in hand with the use of hydrogen. Both technologies are trying to be developed to acheive a cost effective method of transportation that is clean and "green". Both methods are moving towards the common goal of cheap and clean cars that will reach the majority of the public. Reducing the amounts of harmful gasses released into the atmosphere is one other important goal.

Hydrogen Cars
ReplyDeleteThe article talks about how nanotechnology could clean up the hydrogen car. The article shows how three key areas for vehicles are hydrogen production, hydrogen storage, and the fuel cell itself. Hydrogen fuel cells get there hydrogen either by converting liquid fuels or by using hydrogen that has been created outside and stored on the vehicle. Hydrogen cars are the cleanest source because of renewable energy electrolysis. With the use of nanotechnology the hydrogen car can become even cleaner because of solar cells and catalysts in water electrolysis. This would be highly efficient and with the use of solar cells can make that dream happen. While hydrogen cars do not give off anything into the environment they are still dependent on fossil fuels however the nanotechnology and solar cells will help to make cleaner hydrogen.
Lithium Air Batteries
The Lithium-Air Batteries and the Hydrogen cars are both working to achieve a highly efficient and cheap way to make the air cleaner. Both are trying to create cars that are cost efficient for the public and that will not pollute the air or environment by producing the cars or while the cars are in use. Both articles want to try and limit the bad emmisions coming from the cars and limit the gasses that are coming out of the cars and entering the environment.
