Pedal power

steve

think of all that free power going to waste from exercise gear! LOL

might design a self sufficient gym. all gear loaded via DC gennies. one day when i'm bored i'll do the calcs. betcha the power is huge. and people would PAY to generate it for ya! LOL what a scam

It was a remote which 'immobilised' the electrical system; this is a bicycle (with pedals) :lol:

What would you rather do ? (1)sit on a machine that did not move and you had to pedal; or (2) Organise races for the local kids, you supply the bike of course

I'm a bit puzzled, sleepe:
is your first name Frank too?
if not, I assume the question is addressed to me (though it has not much to do with what I posted)

organizing races for the local kids to have them charge your batteries would be a form of child labor, wouldn't it? :geek:

and expensive too if I would have to "supply the bikes of course"
and a non efficient way at that if the aim is to pump water up to a certain level

why not put two bike pumps next to one another and see who pumps the most water in a certain time?
same competition, indoors so all year round, more efficient
but still child labor though

Is a wonderful idea Steve! Just offer it free!

I live in a valley on a farm... the gym is quite a drive if you don't work in town. :cheers:

It's actually being down here in Australia Steve.... I'll find the link....

The gym gear powers the whole facility.... :shock:

I wrote that Sleepe.

In SA an immobiliser can be electronic and mechanical. We have both. You didn't mention which so I took it as mechanical..... pedals immobilised. :flower:

I now understand your puzzlement! :cheers:

Can't find the ozzie one... but here's a few...

Now that is SMART! :cheers:

Hmmmm....... the AQUAPONICS GYM... can see it now..... BREATHE IN FRESH OXYGEN.... IN TRANQUIL NATURAL SURROUNDINGS.....AND BEST OF ALL........ IT COMES FOR FREE!!!! (The demand is so great you will please need to book your session)

Sleepe

To be perfectly frank my comment was allegorical. I am normally ernest even when I'm a little tipsy :drunken:

Is this child labour? http://www.playpumps.org/site/c.hqLNIXO ... roblem.htm

Cyara

Nope. Not child labour. And in third world economics children helping the community with their share of work is not seen as the same as in first world economics. The child labour laws came about to prevent the horrible abuse of children in labour, with hours far too long and conditions appalling.... rich men using children for financial gain....not simple tasks that helped the family stay viable :flower:

a header tank is the most simple battery one can possibly think of and can be used for other purposes too

every intermediate transformation of energy has it's own efficiency losses

Yes, I agree Frank. Feintstar's idea of that larger header tank is superb. You have the water exactly where you want it with no further energy needed to get it to the GBs etc... The simplest battery. I think it is worth the initial expense of building a large header and sump tank.

I must be in a "failing at explaining" period :geek:

but I do my best

... the sump must not be as big as the top tank, Chelle

it must be only as big as the "battery" function of the top tank, that is the volume of water that allows you to leave the system unattended without power source, whether that is electrical, wind or water, or leg power or any other

but the top tank can be much bigger than that, which allows it to provide other functions:

with a bigger top tank you can keep fish in this tank at the density you want (1)

having fish in this tank will provide nutrients for your first row of growbeds (2)

moreover this tank, with a black south facing side and dark interior sides, will stock solar energy (3)

it will also stock the solar energy coming from your sump if that has a black south facing side and dark interior sides (4)

that will all serve as a heat sink and equalize the temperatures in your greenhouse (5)

you can have floating rafts in this tank (6)

win, win, win, win, win, ... win, Chelle

I would make it as big as possible
that way the "battery" function diminishes
but all the other advantages increase

frank

I don't know why but I only saw this now Frank. :roll:

Is excellent. :flower:

The Header Tank is going to have to be very very large.... but once done and paid for the benefits are enormous.

You are right.... I was concerned about the first set of GBs.... thought I would have to manage them differently with adding extra vermicompost or something
And also this way more fish are grown....
It is win-win :cheers:

PS.... what did you mean by this?..."that will all serve as a heat sink and equalize the temperatures in your greenhouse"

the more water you have in the greenhouse, the more mass

mass equilibrates the temperatures in your greenhouse: during the night, it will be warmer than the air and slowly release the heat stocked in it
during the day it will be colder than the air and cool the ambient temperatures in the greenhouse while stocking the heat

you will have much less temperature fluctuations

works like an airco

Goona have to dissagre with you frank i have a proper glass house with 1000 litre fish tank grow beds that hold 200 litres water [ 600 litre capacity] and a 200 litre sump buried with 4 temp censers on a hot day water starts at 17 deg glass house gets to 45 [beds all black] end of day water 20 deg , overnight ambient drops to10 deg and inside temp12 next morning water around 17 deg [thats with every thing closed] so in my book unless a glass house is double insulated heated and or cooled heat sinks do very little i recon for economy go for fish and plants that suit your area for me this is an enjoyable hobby i do not want to eat $30 fish and $20 lettuce

you know better than that, F@F: double sided or not , if you take all mass (water, tanks, growbeds) out of your greenhouse and leave it empty, the temperature fluctuations will be much bigger.
which proves my point: if you want stabler temperatures, put more mass in the greenhouse
it will work both ways: lower temperatures by day and keep temperatures up at night

double sided will enhance that, there you are right
