Do watts from a generator add up?
So I’m sort of new to this project I’m doing. I made a miniature hydro-electric generator a few days ago, and to test it, I’ve just spun it as fast as possible by hand. It made 1 Volt, and the wire I used tested for 15 Ohms of resistance. Using Ohm’s Law, I calculated about .06667 Amperes, and from that, I got .06667 Watts. So since I’m new to this, I was wondering, does this mean that it’s like, .06667 Watts per second, or am I misunderstanding the definition of Watt?
Also, if I haven’t misunderstood (which is doubtful), does this mean that after approx. 4.16 hours, I’d have made 1 kiloWatt?
[4.16 gotten by taking 1000 watts/1kW, divide by .06667 watts/1 second (not sure if the "second" part is right), take that, and divide by 3600 seconds/1hour]
so once again, that formula probably isn’t right, but any help is appreciated.
Thank you very much.

The power is
P = V x I = volts x amprs = watts
P = 1 x 0.6667 = 0.6667 watts
The energy is:
E = P x Time
The time is in seconds or in hours, but not used 3600 seconds to converts. There are per definition.
E = P x Time = watts x hour = watts-Hour
E = 0,6667 x 4,16 = 2.77 watts-Hour
E = [ 2,77 / 1000 ], KWh = Kilowatts-Hour
E = 0,0028 KWh
