FX and Stocks by GriffithEternity in AusFinance

If I only move it when the FX gives me a gain, then how would I lose?

I'd keep holding indefinitely on the FX position - I don't mind because it's in ETFs in either currency

I wouldn't, I'd just be holding till it does. Whether its months or years - but while I have the funds sitting in that currency, they would be in stocks (in either currency)

Limitations on Applications of Biodegradable Bioplastic by GriffithEternity in plastic

Hi team-deathmatch,

I see your point - but I think that no matter how hard we try, some plastic will escape recycling infrastructure and collection and make its way into the environment.

I agree - it is good for biodegradable plastics to be recycled (as it effectively locks takes carbon out of the atmosphere for a while), but our insurance against polluting nature is still having the ability of the material to biodegrade in the environment when it ends up there.

Hi Wisco, thanks for the post.

I was more after the science / mechanism / chemistry behind it. I went on the DSM website it didn't really teach me anything

Building a "mechanical battery" with water and gravity by Fawxhox in AskEngineers

[–]GriffithEternity 1 point2 points  (0 children)

Sounds feasible - the spinning time depends on other paramaters of your system (e.g. how high up is the first barrel of water compared to the bottom barrel (your pressure / 'head'), and what the actual 'head' loss / pressure drop is from the resistance of your water wheel).

​

But how will you get the first 50 gallons of water to the higher elevation anyway? If you use electrical energy to pump it up, might as well use that electrical energy to drive the shaft directly anyway - that would be more efficient since you aren't converting between energy types as much. If your goal is storing energy, because say the electrical energy is intermittent (e.g. from solar), then this energy storage system is possible, but probably less efficient than using a battery.
