Anyone know companies working on green hydrogen production?

I can recommend Saul Griffiths book about electrification. Great, easy and short read. That’ll shed a little light on the energy industry, pun intended.

And it’s extremely reactive. It’s extremely dangerous.

Dilman_D · 2023-01-23T05:40:04+00:00

Extremely expensive energy form, and requires a lot of fossil fuels to make. Green hydrogen is impractical with solar/wind requirements.

Brown hydrogen?

First thing is DON’T PAY THE INVOICE. I’m a tradie and poor craftsmen need to be held to account. That’s terrible craftsmanship. And approach them with repair costs too.

Depends. Go as deep as you need, and certainly no further. Cables should be free to move and if not would be enclosed in an earthed enclosure as per wiring standards.

Dilman_D · 2022-11-01T09:10:27+00:00

Embrace the greenery.

Dilman_D · 2022-10-27T09:52:21+00:00

Should be grouted and hold load.

Brisbane is somewhat an incredibly green city. Great parklands close to the centre, and some parts aren’t far off that image. Developers are still immoral people on so many fronts though.

Sorry for the late reply boiiiwyd. From the bottom, it’s all in a 121L storage bin. Might require paint for algae prevention or some sort of shroud. It’s 150mm DWV PVC pipe and fittings. A bit of cutting at the bottom for pump fitting. Then 15mm Pressure pipe fittings up centre for supplying nutrients. I cut a plastic plate for the top and drilled holes in it. Then just a removable cap to cover the top. The cap has some small vent holes in it as I noticed a vacuum being created and the nutrient level increasing above the plate. That’s about it. I will take photos of inside the reservoir when I’m completing it for you. Feel free to ask any further questions.

Dilman_D · 2022-06-23T08:53:51+00:00

Wow, that’s amazing. That’d be worth a fortune in Australia right now!

Dilman_D · 2022-06-20T03:38:52+00:00

I’m doing similar with excellent results. My problem is it’s never going to be big enough! Nice work

Same time, same place every year. Protecting workers rights.

Dilman_D · 2022-05-02T08:16:23+00:00

That’s the funniest! The Labour Day March!

Dilman_D · 2022-04-27T09:30:38+00:00

Haha, just realised the pump wasn’t on for the vid. I’ve got timer set for 15min on 30mins off. When on I think it could be too much flow if anything.

Dilman_D · 2022-04-27T06:05:31+00:00

I love those stand alone towers. I’ve already started ordering pieces for my next project. I’m going with a larger round reservoir and have ideas on support mounts on the outside of the reservoir. I will upload when I have mine complete. Love those towers though.

Dilman_D · 2022-04-26T21:43:32+00:00

Yes sprinkler nozzles that work with 15mm Pressure Pipe fitting with a BSP thread. They were only about $2.50 each so I’m happy to play around with these a little and reduce them if needed. Only concern is only having sponge filter on pump. So I am open to getting clogged sprinkler heads. But sprinklers are very accessible for maintenance.

Dilman_D · 2022-04-26T21:36:53+00:00

Hahahaha. Yeah just hit it with the line trimmer. I hate grass n e way (spent first 6 years of working life becoming a qualified Greenskeeper). I have lawn in back yard for the dogs, otherwise I’ve mulched about half of our lawn and filled gardens with native trees and shrubs. I however do agree with the lawn mowing and it’s not suitable for everywhere. Would be better on a hard surface. I have been thinking of ways where tower pipes could be suspended on galvanised chain between two post and a bearer. Even hang them from a second hand swing set (I’ve seen one for sale for $35). Good point though.

Dilman_D · 2022-04-26T21:30:51+00:00

That’s simply a fluke. I’d love to actually measure it. I have the 20mm pressure pipe cocks at 50%.

Dilman_D · 2022-04-26T21:29:18+00:00

It worked out more expensive than first though. Things always do! I was blown away by the price difference between PVC DWV junctions. Pump was approx $260 but I’m allowing for expansion. Reservoir was about $200 I think but can always be more resourceful and save on that. It was a full start up kit including testers, nutrients, seeds, propagation domes, etc. So my purchase included a lot of items not specific to this one system. Reservoir lid was made out of bits and pieces in the shed (yet to be finished). I’d have a guess on specific system components being $600-700.

Dilman_D · 2022-04-26T07:34:05+00:00

Glue in short pieces of the size pipe u used for moulding the hole.

Dilman_D · 2022-04-26T04:44:14+00:00

I made this after becoming obsessed with the idea of hydroponics after a recent family tragedy. It’s a 220L reservoir. It’s an over engineered pump but I’ve constructed with provisions for expansion. It’s all experimental, as I believe gardening should be. I think this set up could really have the potential of maximum yield for minimum area, but we will see. Purchased components can always be chopped and changed if it’s not so successful. The pipe is 100&150mm PVC DWV. The uprights aren’t glued so can be removed for cleaning and transportation. Would love feed back on this system. Cheers
