Power Consumption Estimations

I base my estimations on a light bulb (incandescent bulb): 50 watts

TV 200 watts   

Computer: 100 watts    

Car: 50,000 watts

Motorcycle: 10,000 watts

Fridge: 1500 watts   

Oven: 1500 Watts (to warm maybe only 500 watts, but for high heat higher watts) 

Radio: 30 watts

After my estimations above, I searched the internet and found out the following:

A standard TV 188 Watts,   plasma TV: 336 Watts

Computer 40-120 watts

Fridge 1400 Watts

Oven 3000 Watts, toaster oven 1200 watts

Radio (clock radio): 7 watts.

This is a metal latch which cost 28 dollars at home depot. We can build one made out of wood.

Attach the “arm” to the oven door. We will cut a groove on another piece of wood and attach it to the side of the oven. To lock just lower the arm
