Wind Energy

Ya that was a lesson hard earned, in the end the cost of fish is nothing, the first batch p put in 2000 600 baht. I have to a little more work on the small pond where I have gaps. That easy enough and all ready have the wire for it. But, I;m still looking for those birds.

I haven't sealed off the big pond yet that's for next month. Got the grass you pointed out planted for erosion.

Sala between the ponds is almost complete thatch Thai Style. It was interesting watching them build it. There is section marked off by Ucalopatist ( spelling got on idea ) That was used for the frame work. Interesting feeling seeing what you own being used for a productive purpose. Those bugger will grow back. Got short style type of bench. table for under it. I can almost taste that ice tea. I may need a bell for my bamboo pole

This is an interesting article indicates you can grow fresh water shrimp in the same water as the Nile Talpia which is what I believe we have here.

Using the green water method

The Giant freshwater prawn (Machrobrachium rosenbergii) is farmed in Thailand and could be used. Only problem is the prawn larvae require brackish water so you cannot breed them in your pond; you would need to get them from a hatchery (or set up a hatchery yourself) but due to the salt requirement (and also fed Artemia as larvae) juvenile prawns for grow out are not cheap (maybe similar to fish fingerlings) also you need to find a hatchery. Also be aware big prawns will eat small fish.

You could try the local shrimp (like what you see in Pad Thai). They will breed in ponds here and will coexist with fish (although the fish will eat them if no cover). Mother-in-law catches these as a sideline from our fishing lakes and can get about 1 kilo a day when numbers good - but seasonally can be uncommon. You will not get rich but may supplement other income - or provide an occasional meal.

Rick I'm going to move this over to the new thread I started FFFF

I want to use that on since we are talking about fish a lot , thought it would be better and you will also be able to see the point I;m at and what I have done thus far. Hope to see you there.

Yes, I realise it was drifting off topic, and will look up the other thread. To get this one back on track, one of the problems with small wind turbines is height above the ground. In the UK, considered a fairly windy country, a 1 kw turbine will only produce 1000 kwh per year - assuming it is about 15 metres above the ground. Unfortunately many people didn't realise that height was so important and many were attached to roofs at half that height (to avoid planning permission rules) - and they only produce half as much - if that. These systems can have payback times for installation costs of over 20 years. With the wind speeds here i think that would be far longer. Suppliers were also notoriously optimistic as to how efficient there systems were so that caused a bit of a backlash. Of course, commercial wind farms are only built in the windiest of places and rotors are often 50 metres or more above ground. I'm glad i did my research in UK and changed my mind about having one.

Solar power for a small system is pretty viable - (in Thailand, not the UK) as quite a bit of sun. Even in UK it works but installation there is expensive so only worthwhile if you get a government subsidy.

20 yrs ago tried this made money then pond posined. thais do not like competion ask nobie. good look
