  1. What do you mean salaries haven't increased in last 20y ? They did in Thailand and my job certainly went up by around 100% in last 20y ( taking out inflation it still is a rise ) . On topic , all food products are prone to rise in very near future , thx to grain and oil shortage involving the war in Ukraine . What does it have to do with salmon you would say ? Well , a salmon if wild caught , then the oil prices are much higher . If produced salmon then the feed for the fish is much higher . Also , for other food products , if 1 goes up in price , then alternatives need to be found, so they will rise also .
  2. Well , yes , off course , that is always something people need to consider . Getting free consumption always means , more consumption . So if you are using now 10kW per day , better start calculating at 15kW per day . For myself , i am still on my way heading there , since i need(ed) to fix some other stuff 1st .I am getting there but i am also already preparing for electric car and motorbike and complete home airco since prob that will be there . Now my transport costs in Thailand are minimal so that's no issue , but preparing for the complete home airco , i certainly need a few kW more then i would need right now . But do not let it stop you , since the energy is free for many years to come . I mean , solar is there , and yes they need to be produced , but they keep working and are very reliable . Even 30-40y old panels still produce electricity . Batteries are a different thing , but if you put out 10-20% of the budget for electric a month aside for replacing them , then you can be sure that even complete failure can be replaced without issue.
  3. Li batteries can and will go up in fire once a while . That is a fact , but everybody got several Li batteries in their home and pockets . All smartphones , computers , and similar equipment are all powered by Li ion batteries , and nobody gives a sh/t . There are also plenty of examples of cars which do/did run on gasoline , gas , diesel , which went up in fire . Some cars even got withdrawn after production because of high risk of fire in a accident .The batteries will get safer but there will always be fires because of high energy/high currents running , same like there are many fires every year in homes thx to short circuits . Can it be better , yes , but remember this . Fuel driven cars are basically end of development , same like CRT TVs were 25y ago .And like the CRT 's being replaced by plasma , lcd , led , oled , the technology is growing fast and is getting better each single year .
  4. The rebar is not needed for outside to inside pressure . Yes , certainly not so many rebar or concrete needed for a 1m pool vs a 2.5m pool , but being completely in ground or not does not make a lot of difference because it needs to keep the water in . You can use a steel freme , this way you do not need rebar , because the strength comes from the steel , not from the concrete . Concrete impact strength is low , so the pressure makes it crack without rebar . Concrete however is cheaper then steel , especially is you want a nice finish and a deeper then 1.2m pool . Steel structure pools are build with a liner , not ( i never seen or heard it) with tiles or similar .
  5. If you use metric system it is all so easy , instead of 2 fingers and 1 coffeecup and 2 fridges , you can use the very simple metric system . 1l of water is 1 kg , 1m3 is 1000l is 1 ton . You can even widen it to pressures , 10m of water equal 1 bar . and also equals the barometric pressure ( so you can't suck water higher then 10m , that is impossible ) . So back to the topic , yes a pool of water does create some pressure on the soil , 16-20 ton in your case , equal of about 10pickup trucks ( in imperial system ... just joking )
  6. Land prices in Isaan are the same as land prices anywhere else . Meaning they can be very low or very high depending on road access , sunken or raised land , land title , proximity to city/village , present owner ( and the need for money) ....,....
  7. https://gettopics.com/en/calc/water-heating-time 100m3 of water is a lot , but depending on where you are and how many you want to heat up all is possible . If your pool is 16c and you want 28c then it is gonna proof a difficult task ( or expensive ) . If you have some room in the sun , a simple homemade solar heater can well do it . The sun's output is 1000 watt/m2 . So that,s a few kW you can put inside your pool for free . Add a foam blanket at night to reduce temp loss during the night and in a few days you might have gained enough . After that , a heat pump might be the answer . Especially a combined system were the cold is moved inside home and the heat in the pool . Everything is always possible and they do not have to cost fortunes .
  8. It is surely worth it . Only covering your daytime use 6kW per day , you need roughly 1.5 kWp installed . This is give or take 4 panels of 400 watt ( 18000 baht) . A grid tie inverter from Sofar 1500Watt does set you back 9500 baht . Then some bits and pieces and a fuse box , lets say another 5k . So lets say 32000 baht investment for making roughly 180kWh per month , savings 800baht per month , so payback time around 3.5 years . The fusebox is pretty reliable piece of kit , the solar panels are also very reliable , there is not much going on there . Only thing which does break down are the inverters , but expect a Sofar to live at least 5y , before replacement . Remember , this is a grid tied installation . According to different grid tie inverters , you can cover only your own consumption , while the grid is alive . So your meter will not spin back and this is "semi allowed " . Meaning , it is grid tied but since the meter is not running back , they don't care and basically is no issue . 2nd , if you do not install the anti reverse clamp , then the meter will spin back , as a full grid tied system . This is not allowed , but is used many times . Only , remember that your electricity guy who does check your monthly expenses , does not see the meter running back . This is pretty easy to avoid , if you shut down the panels around the day he comes ( he does come always around the same date , +/-1day . ) . If you do go this road , then you better adjust your install , since a 3 kW inverter is only like 4000 baht more and the fusebox is the same . So it only takes a few more panels and you can make even your complete monthly consumption ( payback time this way can go to around 2.5 y ) .

    Roof Gutters

    Been looking at installing a roof gutter since the overhang of the roof is 1st of all not big enough to keep water splashing down hitting the lower end of the wall and doors (wood , preparing to change those to alu or upvc , would never put wooden doors again since unless you can you can keep them 100% dry all the time , they will need replacement after 10-15y ) . Addding a gutter would add another 20cm of overhang . And a 2nd reason is to reroute the flow of water from the roof to a "removal point" which can be a tank , but can also be just the street instead of adding more water to the land . The land itself is raised quite a lot so it is no issue of overflowing the land from streetside .
  10. It won't . You can charge any electric car by standard wire from plug ( non charge station , i think max is around 2000 watt ) . This will still effect the grid if many people around a same block do at the same time , but the 7kW and more charging stations , they are effected . IMHO most people do not need these things , as they require many times higher incoming lines to your house . If you are doing less then 100km per day , no problem charging from your normal outlet .
  11. Will be more and more around the world , more and more things are running electric and cars do need a lot of electric . The grids , allthough in many countries are charged , are not upgraded to that job . It is just a extra reason that cheap energy will be a thing of the past , since the new technologies need large investments fast and are clearly payed by 1 person ( aka the consumer) . It is also a reason to go off grid as fast as possible , if you are able to do so . It will come with a cost , no doubt about it , but it will pay itself back quite fast .
  12. I did not get covid , i did stay away from anyone for 2.5y , except for work . And yes you could very well take it literally , no visitor , no restaurant visit , nothing at all for 2.5y . Having said that , So the rules are getting more stronger again , i am fully vaccinated , i did not need a negative test right now to enter , now i need one ... fails me why but ok .
  13. oh comon , i did spend a few days in Pattaya before going to the village . I did wear my mask in the daytime outside , but in the evening practically i never worn . I did have 1 with me but nobody wore it . And basically it is as stupid as it can be . Like i said before in another topic , i am not at all against masks , in fact i am all for it . However , it must be used have its function . What's the point of wearing a mask when im walking in the daytime on the beach and spend 2 hours in a crowdy nightevent indoors where its crowded and no mask wearing ? I just fail to see the use of it . If it is for covid you can just ask also to wear a red nose and big shoes outdoors , and inside do what you want . Just the same .... I repeat again , i am not against masks , i got a bucketload full in my luggage , and i do wear them , but in most cases over here in Thailand i just 100% fail in comprehending why . Like somebody showed me (Thai person) of a woman in rural Thailand complaining about her aircon not working and breaking down after a few months , while the house it is installed got no doors ( a blanket as doors) , huge gaps under the tin roof , non-insulated open space practically ... . Basically it is just the same , whats the point of it ... I still wear them here in the village when i go out of the house , but there's people all the time coming in , with their mask on , and taking it off when they entered , and then we are all drinking and eating here together ... as stupid as it can be .
  14. Freezers are nothing , they are large consumers in any household , but that is because of the 24h/7 consumption . On hourly basis , it's a ok load . The circulation pump if it is correct , that might be a problem . Is that running all the time ( can't be since that alone would be way over your 350 kWh use / month ) ? You need to check it , is it a start stop with timer ? Also , a 2500watt pump is not small , can be but it certainly would be a problem . Startloads on such things are big and most solar inverters do not like it . There are ways around it , like the low frequency inverters which are better suited for it , but otherwise you better check in front . You could also run it like the additional aircons on different grid ( aka your incoming lines split between your normal household and then the other ones who only run on the grid ) . Sounds complicated but really it isnt , since you need fusebox for you solar inverter anyway , 1 is powered by the inverter the other one direct from grid . Also Your aircon in gym , i guess you mean a 9000btu unit , non inverter type . Thats ok for a 5000 watt inverter . 9000 btu is 750 watt engine , so peakload is still well under the 2hp ( 1500watt) which in general is the max a 5000 watt inverter can handle .
  15. Well if your electric bill is 2800 baht for a 8 baht rate , then it is very possible . That's 350 units a month or +/-12 kWh per day . It also means you aren't running all the aircons , prob just 1 in the bedraom . To offset that amount you need to get around 4 kW of solar power , a 5000W (are your aircons inverters , very important for the startloads!) hybrid inverter , and 10 kW battery ( for those inverters it would mean 48V 200 Ah ) . Now this is a minimum , but it will cover a 350kWh load ( most of the time) . Adding more batteries will always be beneficial , since doubling on those would create a large buffer , for less sunny days , and or keep your batteries just last much longer . You can think about it is all gonna cost , depending on your provider of all items . solar panels now , most are 1.2 baht per watt ( there still are a few cheaper around ) , so 4kW sets you back 50000k inverter between 15000 and 50000 all your choice batteries , 10 kW , 50k with a bit of looking around the rest are bits and pieces , like mounting rails , switch box , wires ... just make that a easy 10k . Do not forget your peakload , idk you installation and what you do , but if you got a like a 4500 watt water heater , or a swimming pool pump of 3hp , then the inverter just won't cut it . Then its over to the design table .
  16. Installing them alone would not be realistic . It can be done , but yes solar panels aren't the lightest stuff around . The difference between all of them is minimal , if you are worried about it . You do have +500W panels , which do contain more cells , and are larger also , they come around 30-32 kg . The standard 72/144 cell type are in size all roughly 2m*1m ( there are differences ) , and vary in wattage from 300-450 watt depending on brand /type/efficiency .. and are more or less 25 kg each . Then there are the smaller panels , they are off course lighter and can be installed alone , but most of them ( the 60cell type is not so common anymore) are not for "larger" installations . I would not see anybody putting 10 times 50 watt in string to a inverter .
  17. yes , exactly the same i said , with even more examples . Any country can impose any rule they want , but they got to be useful in a sort of way . Basically , i see 0 changes from behavior of people then before covid . Now i do understand it , but then the masks have to go also . In the village here , people are coming over and drinking and having food together , just like they did before . Wearing a mask until you go to other people and then sit down and talk eat together in group and then leave put mask back on , until they go other place , doing the same well then there is simply no point at all . 1st line of defense against spreading the virus ( or any virus that is) is stopping human to human contact . Masks do work in places where you cannot avoid contact . Now its wearing a mask where you do not meet others and when you are making contact with others , take the mask off .
  18. nahh , it's just the press jumping on it , after covid . There's like dozens of diseases breakout every year , sometimes something is more common or happening but nothing to worry about . Few years ago it was meningitis , this year there is a hepatitis and monkey pox . Later this year maybe 1 or 2 more being picked up by the press . BTW , if you are a bit older , and you did get smallpox vaccination , you prob are protected also . Nothing to even to be the slightest of worry about , leave that to virologists . Unless you see a big outbreak in 1 or 2 places , then it is time to worry , not for 1-2-3 people .
  19. Virus particles do not life long in open air , and they are spread around diluting the particles . Indoor circulation with a taxi driver makes me breath in the same air as he breaths out . Then a facemask does not help ( a FFP2 worn correct still does help ) .
  20. I only made a observation . They can keep the rules as they want , it is their country . Same like the Chinese can spray the aircraft runways with disinfectant , 0 result but hey if they like to do , up to them . I only observing the way the masks are worn , which in many times is just not working at all . For me 10 baht for a few masks is nothing , i got bundles of masks ready , even 3M FFP2 same like worn in the hospitals for working with covid patients . However for many people the 10 baht masks is money they can't actually miss . In this regard , make the masks use as good as it gets , not a stupid feature which does not stop anything .
  21. And that is why you got the vaccine .... vaccines will not repell the virus . If you do get in contact with it , you might get infected/sick . The difference is that your body now comes in contact with something it is suppose to remember , thx to the vaccine . This way , your body will react faster to find the infected cells in your body and you do get less sick . It boosts your natural own defense . Would you have been more sick when not being vaccinated , well in individual cases , it is impossible to know . In general population , yes , dramatic reduction in serious illness / death .
  22. Since i am now 9 days in Thailand already , i can honestly say , that the way the people are wearing the masks , it is just plain stupid indeed . Very few are wearing the masks correct and wearing them at the most idiotic moments creating 0 result . Even yesterday i was watching the Thai TV , they interviewed somebody and he was wearing 3 surgical masks . Wearing masks in open air does virtually nothing , on motorbike not even virtually nothing , just nothing at all . This is even when wearing correct . The risk of somebody getting covid from walking on street is when not talking so somebody , in a not too busy place is 0.0 chance of getting covid . Indoors , masks do serve their purpose , but spending a while in a taxi while the recirculating sign of the airco is on , well masks again do not help anymore. I am not against facemasks , but like it is right now , i'd rather skip them for 99% . Masks should be used indoors or in public transport and the air inside should be vented out as much as possible at all times , in order to get virus particles out as fast as possible .
  23. For the time being it was useful to have lockdowns . They not have been the most pleasant times , but they do cut down on movement of people aka spreading virus . It won't stop it , since people are not machines , which they did try to do in China in some points (or still are) . I could live perfectly happy on my own , but i know most cannot . Anyway , lockdown did serve its purpose , slowing down infection in a way hospitals can cope with the load . After a while , so many did have the infection already , and then they will not go to hospital even if they are infected again , leaving less and less people going hospital , even when the infections surge . This is the point where many EU or other countries went before . It is not ok , but most have had it , and the amount of others are in much smaller amount that hospitals can cope with the workload .
  24. Bank to another bank in Thailand was 20 baht transfer fee , long before BTC arrived . WU got different rates , in older days much higher and also at the spread ( buying /sellling ) . Nowadays , lots of the fees on WU have disappeared , but still got huge bad spread rate ( aka the rate you get when sending money to Thailand ) , thats why Wise or other websites are used a lot more now .
  25. If you are in Thailand then you should know that Westernunion was used long time before any BTC or any other was used , with nearly 0 waiting times and small fees , certainly less then SWIFT . This is exactly the BTC people say , oh , i can transfer money everywhere fast with less cost .In Thailand i could do bank transfers before BTC and go inside ANY bank and for 20 baht fee it was instant in the other persons bank . Westernunion was used a lot also , nowadays its Wise or another service , and maybe they work with BTC , but it does not give me any reason to have BTC myself . If it takes longer then 1 second to be in another account , it is just because the bank likes to keep the money for themselves as long as possible . And then you say , yes but now i do not need to use WU or Wise or similar , true , you need to use a BTC trading platform , which then is just the same ...
