This is my first time posting in this forum so please have patience. I am working on a small wind turbine design that will output 6-22 kWh (30kWh would be ideal but is not very plausible) and will be used to charge a lithium ion battery. The turbine will be used with wind speeds of 35-80 mph. The current desired dimensions are 6-9"L X 3-5"D. I plan on using 2-4 generators to distribute the load. The best generator that I have found based on size alone can only produce a combined 1-2kWh, that output is well above the power curve, and wouldn't be very efficient. Is there a way to amplify the power to reach higher output or does anyone know of a good compact turbine/ generator design that meets the desired output? Once I know what generator to use and its specs, I should be able to calculate the rest.
