Your Questions About Windmill Lakes

Anybody remember this movie?

I remember a made for tv movie about a monster in a lake or rock quarry. There were kids in it an in the end the monster turned out to be a quarry digger that was submerged and would rise whenever the wind blew a windmill and air would force up the old digger. I know this is pretty vague, but it’s about all I remember.

Thanks

Can someone help me name this movie?

Older movie, mid 80s perhaps. I have not seen it for years, so the only details I remember are a younger teenaged boy trying to dive to the bottom of this murky lake, which looked like a flooded rock quarry, to investigate what he thinks is a monster. It ends up being a submerged excavator and air bubbles making the shovel move (that is how it ends). At some point in the movie, he builds a make-shift diving rig with, I think, a barrel and a windmill to pump air? Something tells me the movie was Australian as well, but not sure about that.

Is this a viable idea for pressurized rain water collection system?

I had an idea at work the other day. If I collect rainwater in a large container, say 200 gallons. Can I pressurize it using a windmill that pumps air. My uncle has one that runs an aerator in his lake. Its not much but over time the pressure could build up if its going through a one way valve. I would also put a pressure release to keep the tank from becoming over pressured. The problem I have is how to get rain water in there and not losing air pressure. I could then use the water to flush my toilets and use on my outdoor spickets. Do you think this could work? Do you know how to fix the entering water issue?
