Costs

It's surprising to see a top-loader that has such a heavy motor. Most top-loader washers in the US are less complex relying upon a simple motor and belt drive system and not direct drive.

The output figures are nice but unless the power is stable and clean your appliances won't last long.

The 800 Watt figure is not enough to power all the stuff mentioned. In fact after inverting the output to a clean 120V AC (NZ probably uses 240V) you'll have only around 700 Watts...and that's only enough for maybe a TV or computer but not all of the appliances listed. In the US the typical toaster uses 1500 Watts. A hot water heater (around 40 gallon) uses around 5000 Watts (peak).

Depending on what you are using it for

I actually like using 240V in my own home, just can't make any mistakes. There's all ways somewhere in a big city you can get things like that. I started using it for some stuff right after college and saved a big chunk on my utility bill every month.

There are 240v lines in your home, this could be used to run your electric stove or dryer. So depending on when where and how this is being used it could save a lot of money.

If you add an idea like this to aquaponics, earth sheltered construction, light fiberoptics... I'll do a sketch but you could feasibly make sustainable systems that can feed cities the size of Denver in areas that would normally make terrible farms, like dry farmland in the midwest. That also produce soil, fresh water fish (100s of species), animals for food and pets (dozens of varieties), electricity from sustainable biological resources. Which could feasibly last for 100s of years and consumes minimal resources. Would also make one heck of a place to live.

I wonder if

this could be adapted for a large fishtank to be powered by the motion of the fish?

This is genius, thank you for

This is genius, thank you for posting it. Very Fallout. I can't wait to try making one of these. Could do it straight from a strong enough stream and not even have to worry about municipal water. I'm stuck on solving de-icing in the winter. Figure a fishpond heater wouldn't quite be up to the task.

why

Why do you want to keep a fishpond de-iced? If its for generating electric, a pond/stream which freezes solid is not going to be powerful enough to generate much electricity. if it's for keeping the fish alive... use native fish, and make sure the pond is deep enough.
