Nice find! Lots of goodies on that.

I've got Uno Turbo front brakes on mine. Work well, but end up pushing the bias even more forwards. I fitted Fiat 132 rear calipers (same caliper, bigger pistons) which has sorted the bias out a treat, but I've ended up with a bit of a mushy pedal. Works, but doesn't feel as nice as it did. After I sort the engine I've got a bias setup on the mind.

Would be interesting to see the engine bay. I like the relocated coolant tank as it's all a bit snug in mine for air filter placement (apologies, only pic I have of my engine bay has my chops in it...):

 

Ill take more pics later...

So many mitsubishis in this thread.

The X1/9s have a factory 5 or 6mm spacer, I know chaps who have been pulled up in it and have had to prove they were factory...

Mr Pogward, how is hot water created with your system ?
if you havn't already, look into Paladin style divertors for PV based hot water

Ah so there is a bit going on.

There is a solar powered cabin that I work from that needs a bit of cloudy day capacity. All the dumb ideas are for this.

The house does not have solar but it probably will later. When this happens it will definitely have a solar hot water diverter.

I can understand your DGAF attitude more now I see that your spa is in direct line of sight to the neighbours

Na the extensive real estate holdings of the pog empire means that that is our actual house. The only one spying on my magnificent manlyness porpoising in the spa is the middy.

Of note is that the shed is significantly better appointed than the house as you can see.

Yeah, up to 10kWh in a hot water cyl, is def cheapest domestic energy storage. But you can only drink so many cups o tea. Hey, is there a solar to Nissan Leaf box? I have an idea on how to get rid of the rattle in the X1-9.

Seriously tho, an ev you can draw from makes good portable battery

I have had a quote to put 16 panels with micro inverters to offset the house use and with a unit to dump the excess into the hot water cylinder, it was surprisingly cheap, like 16k.

So maybe at that point I'll just plug in, but meanwhile this investigation is a good time.

Best idea so far.

Time to buy a cheap EV, run a cord to it and motor around for free*

 

*RUC not included.

I have also thought about buying some old leaf batteries as cheap storage.

Go dig up the system from Somes island?

Electrolysing hydrogen sounds like a good time

OK - scrap iron and brass batteries then?

Looks like it, unfortunately I just dont have that much elevation. I do have another two panels so can potentially generate 1.5kW to fill up scrap batteries.

Im not sure hydro is the way. I found an online calculator for micro hydro and it seems that to make 800w for an hour with a 10m head I would need 54000 litres...

Nah, just yoink up the volts a bit. 48V is extra low voltage, but will still need enough copper for 20A/kW, which is a bit beefy, but if there's a way to run 230V / 600DC in ditch, you could use doorbell wire

Yea so I am thinking about replacing my inverter and charge controller (due to that noisy power stuff we discussed) with a solar inverter unit of much higher quality, and the ones I have been looking at have a 230v input for plugging in to shore power or a genset. So I guess running 230v hydro isnt out of the question....?

The most convenient arrangement for this would put the hydro something like 150m away from the cabin.

Fuck now I have to work out how much head and capacity I need.

I actually know a man who just replaced a shitload of his batteries in his solar setup, even at 70% soc I could stack up enough of them to be sweet....

Yeah, but who cares if its inefficient when the input power was free?

Any extractable energy stored is a bonus 

This.

Hot water is no use to me in my cabin, and extracting useful work from even 100deg water is mechanically intense.

Steam is a different story but not suited to slow, intermittent power input.

I am keen on pumped hydro but while I have a good fall on the land my cabin is at the top of my property, this makes the power cabling back to the cabin very lossy.

I might be able to convince my neighbor that another 25k litre tank up in his paddock above me is a good thing.

Why air? for shits and LoLs, or for cheap storage / direct mechanical?

I see you're looking for 0.6 * 24 is about 14kWh, so $pendy conventional  battery.

You got a handy hill? Pumped mini-hydro?

Also, there's some cheap big electrical battery tech I've been considering playing with.

I watch too many youtube vids for off gridding.

But I have a certain amount of power capacity on a sunny day that goes to waste. My battery is fully charged by 9.30 or so and all that lovely power goes nowhere.

And sometimes I need extra charge on a cloudy day.

So I have devised many schemes for capturing that power to use on the cloudy days, and this 'seems' like a relatively simple one.

I have also thought about pumped hydro but the infrastructure requirements are a bit too hard out where I am.

I have thought about winching a heavy weight up then letting it fall down and spin a genny, but my P=mgh or whatever it was told me it would need to be a very big weight lifted up really high.

I have thought about a sand battery heated by an element, with a stirling cycle engine sitting on it.

There is no wind in Nelson and in particular in the valley where I live.

So now I have the scheme of several old gas bottles pumped up to less than they are rated for, spinning some sort of air motor/generator as needed.

I also am looking for an old multifuel Lister genset, so all my waste oil can get used up.

Any othe suggestions are happily considered, particularly how to store my excess solar (and yes I know more batteries, but that is no fun).

Mean, keen to see how you get on, my brain is poisoned with having worked with commercial high pressure systems and knowing how complicated they need to be.

 

I am hoping for a fairly simple solution, but that is probably the eternally optimistic dickhead I am.

Large tank will be large, and heavy for that pressure.

Bit of weight and energy to carry around a couple of G's on the back

This will be static, its backup for my wee cabins solar setup....

Yea I did the obligatory AliX search and saw that. A strong possibility.

This sounds like hydraulic pump territory,  could you build an air over hydraulic accumilator? You can get those small electric hydraulic power packs for for tip trucks.

I shall have to investigate this. I have no idea how an air over hydraulic accumulator works..

Edit; on some cursory googling I am not sure that has the capacity I am after. The key is to have a lot of air at a lot of pressure so getting something like 600watts out of a generator for a day or so.

I did a basic spreadsheet and its a lot of air.

AC is in the 10-15 Bar range.

2000 psi in a gas is multistage/intensifier realm cos big ratios = heat

I'm assuming a bottle of Nitrogen is not on the possible list?

It is to make an air battery, basically use the excess solar I generate to pump air into a large tank. Heat shouldn't be too much of an issue as I wouldnt think it would be fast.

But a slow high pressure pump is key, I am just not sure what that is.

If I were to find a high pressure, low flow 24v air pump on the cheap would I find it in the form of a truck AC compressor or the like?

I am talking up to 2000psi or some decent fraction of that sort of pressure..

Fuck yea!

Sounds like you need a turbo jet turbine :p

Ah man I looked at making a turbine out of a turbo, just need to sort the injection situation /probably a shitload more to it.

Also using a waste oil burner to make steam to feed the same thing.

So many dumb options, I should just choose one and run with it.

So jelly
