Demand response are the changes in electric usage by end-use customers from their normal patterns of electricity consumption to the price of electricity over time. Incentive payments are set up to lower electricity use at times of a high market price. In electrical grids the demand response is similar to dynamic demand mechanisms.

Dynamic demand is technology for adjusting load demand on an electrical power grid. There is a difference between the two is that one responds to requests to shut off where as dynamic just shut off when there’s issues in the grid. Demand response is used in large and small commercial and residential customers.

We chose to do our project on solar power. As a group we decided to build project very similar to the solar cell lab from which we will collect the solar energy and acknowledge how it works. Since we visited the museum of science we decided to create a device that can collect 1000 watts per square meter under good sun. In order to construct our experiment we will need two three inch circles from white construction paper and 2 three inch circles from black construction paper. You then need to get four same sized plastic beverage containers. You need to put one black circle and one white in the containers and then put 1/4 cup of cold water in each and record the temps. Then we need to place the bottles in the sun. Checking the bottle every five or so minutes we will then be able to see the difference in temps between the white and black circles in the containers. The good thing about solar power is that it doesn’t give off any greenhouse gases. Solar power is Eco friendly and beneficial in regards to having to pay for typical energy.

In this lab we had a tube with magnets that moved back in forth when shaken and within the tube was wires coiled. Faraday’s law states that when changing magnetic fluxes through coiled wires generates electricity through the exchange of currents and voltage. We tracked the number of shakes within 30 second intervals at different rates. We then attached the wires to the NXT and counted the number of shakes in order to measure the voltage. We recorded this three different times at three different rates. The computer recorded the voltage values and then opened them onto an excel spreadsheet. We then used the equation e=m^4/volt and sumof^2 and all of the values to receive the average value from shakes. After we created charts, we found that the faster you shake the greater the voltage. In my eyes this lab was created in order to understand how power can be created by something so simple and to show it as a source.

Tom Vales came into our class and showed us a few electrical inventions, majority of which are used in our everyday lives. He introduced the Tesla Coil. The Tesla Coil is a resonant transformer circuit that is used to produce high-voltage, low current, high frequency alternating current electricity. This device was created to transmit electrical power without wires. An antenna would be constructed to pull the transmitted electrical energy into the electrical system. It can be considered a simple radio transmitter that operates within a broad range of high frequencies which transmits power and not information. This is similar to how we receive wall electricity.He showed a hot air engine which consisted of a cup of hot water and the steam made the contraption on the top move because the the temperature difference. This is considered to run on solar energy. He also presented a sterling engine that was a motor that was spinning. This was the substitute for steam engines in replacement to create power for machines. John Petleys copper and bismuth was also shown. This is when the invention is heated on one end and cooled on the other and then creates energy. He briefly spoke about the mendesedo motor which floats solar powered magnetics. There are four solar cells that make a current through the wire to propel the machine making power. In conclusion Professor Vales showed us a few different tools doctors used for quack medicine when referring to alignment. Having him visit class was a nice change from our normal labs. We were able to sit back and learn about these inventions without the stress of following a specific rubric.
