I want to make a dynamo which can produce electricity. My requirements for the dynamo are as follows.
- I need to charge my laptop through this.
- I want my laptop to run for 1hour with this energy produced.
- The dynamo should have some handle to that I can rotate it with my hand or connect to some rotating entity to generate electricity.
I want to know the following 1. How much energy required by a personal laptop to run for 1hour. 2. What are the items I need to build the dynamo? 3. What are the specifications of the items needed to build this dynamo? I need the steps and mathematical formula and calculations also, the way you calculated the specification of the item. I mean like the strength of magnet, the size of armeture, the minimum speed I should rotate the armeture etc.
Please help me building this device. I would be very much thankful to you.
