Document Summary
More need to have electric cars for the future. Has potential of removing gasoline consumption but there are still problems associated with making the electricity. Incandescent light bulb, luminous flux (lumens) 500 power, 40 watts, lifetime 1000 hours. Compact fluorescent lamp (cfl) luminous flux 500 lumens, power of 11 watts and life time 10000 hours. Light emitting diode (led) luminous flux 500 lumens, power 5 watts, and lifetime 50000 hours. Increasing the amount of salt would change the cloud levels in certain areas cooling the earth. Difficulties in managing the atmospheric levels, the battle is constant as at most a certain substance only will stay in the atmosphere for a year making it difficult to force these changes. In past experiments, we were trying to answer the question, how does the world work?" not how do we make the world work for us? . Learn from past for clues to the future.
