Obama’s Clean Power Plan

The temperature has been rising since the year 1901. The may cause of this is because of CO2 emission. The US is one of the countries with the highest CO2 emissions. High CO2 levels is also the reason for the insane weather storms that have been happening since 2012.

Obama’s Clean Power Plan will help reduce CO2 levels and cut peoples’ electric bills in half. By finding ways to find less expensive alternative energy sources people will be able to pay less. Also people are excepted to become healthier because of the reduction of pollution in the air. The plan is for the Environmental Protection Agency will propose guidelines for each state to follow. The EPA will set a goal for each state for how much CO2 they should be cutting out and the states will try to get to that goal. The plan’s goal is to cut electricity bills by 8% by the year 2030. Overall Obama’s Plan is quiet simple to save money and be healthier the US needs to find ways to cut down on CO2 and get more product for the energy used.

Robotic Car

For the past 2 weeks in we split into partners built a robot car and discovered how to program it to drive in circles, different directions and different speeds. Building the robot was actually quite confusing even with the directions because of all the different lego pieces that went into it. Besides what is shown a battery had to be attached to the bottom of the car to give it power to move. Robotic Car BeforeRobotic Car After

 

Using a USB chord we were able to input instructions for how the robot should move by using the computer program Lab View and then transferring them from the computer onto into the robot. As my partner and I tried programing different speeds into each wheel we realized that keeping the wheels at the same speed allowed the robot to move in a straight line. When we changed the speed of one wheel the robot would turn in a circle. Another assignment the class got was to see if the robots distance traveled could be calculated before the robot moved. By taking the diameter of the wheel in centimeters and then multiplying that number by .01, so that the number could be converted to meters. Finally by multiplying the product by Pi the final answer gives the circumference of the wheel. The circumference is important because the distance traveled when a wheel does one turn is equal to the circumference. Using LabView the computer is able to calculate the number of times the wheel turns. Telling the computer the circumference of the wheel and multiplying that number by the number of turns allowed by the computer to calculate the distance traveled. My partner and I got these results:

Results

 

There was only some difference in my and my partner’s results the error is most likely from the diameter measurement being incorrect. In conclusion however it is shown in this test the less amount of power the car has the less distance is traveled.

Automobile Industry Increasing Gas Milage

The Automobile Industry hopes to have mpg in the 30s by 2016. By 2025 the industry hopes to have this numbers basically doubled.

Goals for MPG MPG Increased

The two main ways to increase gas milage that the industry is looking into is electricity and a start-stop engine. An electric car would run on electricity which would need to be charged every once in awhile. A  start-stop engine is an engine that stops when the car is not in motion to avoid gas waste. Although electric cars are now a common thing people are still uneasy about the start-stop engine. What happens if the engine doesn’t start again and the car is stuck?  Automobile companies are still try to find ways to get around this. Engines cannot start all at once so what happens if someone in a traffic jam wants to move into an opening? Before this is common practice companies need to learn more about it. Basically there isn’t really a best way to increase gas milage without building an entire new engine.

MPG is tested in a lab where a car is run in a simulator that goes through different environments and different speeds. City Driving Test Highway Driving Test

Many people are afraid of the cost because if the technology of a car is more high tech it is more expensive. The industry argues with that even though the car is more expensive the savings in gas will be tremendous. Therefore once the car is paid off it will be worth because u will be cutting your gas bills in half.

Cost Compared to Savings

G.M.Os

It is completely normal for anyone to be nervous about anything they don’t completely understand, the problem is that sometime people use their fear to spread false statements around and try to pass them off as facts.

Genetics is a topic that is still fairly new and we as a world are still discovering new parts of this topic. There are many people who are afraid of G.M.Os but are afraid of them for the wrong reasons.  For one many people are afraid of G.M.Os because they supposedly cause cancer in rats. The study that came out with these results is frowned upon by many scientists because the rats used in the study are known for growing tumors on their own. Also the sample size i.e. the number of rats used was not a big enough number to come to the conclusion that rats get cancer from G.M.Os. What many people are not seeing or perhaps don’t want to see is that G.M.Os could help many people. By using G.M.Os crops can be modified so they are immune to certain virus and to drought which could wipe out a years harvest. By using G.M.Os people can worry a little less about having a food shortage. Also people have been cross breeding plants since way before people knew anything about genetics. G.M.O plants are not that different than two plants that were crossed. The only real difference is instead of cross breeding the plants a scientist just takes the genes they want and put them into a knew plant which is exactly what happens in cross breeding minus the scientist and can take a lot longer.

Although there are some things we do not know about G.M.Os and yes they could be potentially dangerous scientist run many tests to make sure that food is safe to eat. I think if people decided to learn about G.M.Os and the actual facts and didn’t hide behind they’re fear of change people would realize G.M.Os aren’t that bad.
