A man has been spotted this morning on Patong beach riding up and down the beach sat on the back of a giant Killer whale.

I'm under attack from dragonfly's. There's thousands of them help!

He looks friendly enough to me. You should have stopped and said hello!

While we are on the subject of inventions, anyone invented a good hangover cure?

Have to say it's only 23 outside but good stuff. Good fun and I agree George don't stop, keep going. Keep on trying. Remember what he said, you get nothing at all for 2 in a bed!

You'd have better luck (if you want a cheap and homemade deal) pumping the water from a well through a car radiator and blowing air through that. I think you'd need a lot of those to do much good but at least you wouldn't be fighting humidity. If you had a high volume/low pressure pump it wouldn't take much electricity to run it.

You aren't going to beat air conditioning though because by its nature it also removes humidity from the room. If it was possible, I'd rather remove the humidity than lower the temp if I could do just one. Hot dry air feels a lot better than hot humid air.

They call it air conditioning because it does more than cool. It also dehumidifies or they'd call it a cooler. In the end you really need air conditioning if you're going to be truly comfortable.

Cheers.

you are correct NS but i would like to add that dehumidifaction is possible if the well water is considerably cooler than the desired room temperature, e.g. well 18º / room 26ºC.

that applies to my well but unfortunately i can only pump 5-6 m³/hour before the pump sucks air and cooling even a part of my home would need a much higher volume of water for which, as you already mentioned, a lot of energy (pumping water and recirculating air) is required.

in my case i thought of the solution using the 18ºC well water to cool condensers of regular split units but the low pH (4.5-5.3) and low alkalinity (20) makes the water so corrosive that expensive Titanium heat exchangers are required, id est zero sum game

Ok, so let's say that in my laboratory that I've built at the side of my house in which I conduct all my experiments that I have managed to drop the temperature up to 10 degrees lower than the outside temperature using only water PVC pipe and a cheap fan. Surely if I can blow this cool air into my living room and extract the hot air my room will cool, yes or no? I would love to post my results so far but if another like minded scientist gets ahold of my invention with more knowledge on air cooling than me then I'm afraid that he may get the accolade that I deserve for all my hard work.

congratulations! i never achieved in my 17m² workshop a delta t of 10ºC (when ambient is 35º) although it's equipped with a conventional aircon, capacity 12,000 btu/h.

and like you i refrain from publishing details of the engine i designed and built which uses the hot air spread in the internet by wannabee engineers cum inventors who are beating the laws of physics 25 hours a day because they skip lunch break.

This is exactly what I'm talking about, someone with a good education, no doubt better than mine but way too much stuck up there own <deleted>.. So much to say but when it comes to getting the job done useless. 18 degrees inside now I'm off to put my onesie on.

Good stuff George. I love listening to the can't be done. I myself am a can be done. It's only can for me there is no can not. Good look with your cooling system, don't listen to the doubters.

Regards, a cool sammychong.

@littlesammychong,

Even if you can achieve 5degrees C difference between inside and outside temp its great.

I posted above about an invention of students with copper pipe under the ground and also above the ground for evaporation. Such a system can also be used for blowing colder air into a room.

Besides passive cooling and using a whole house extract fan plus blowing colder air in i also am convinced convinced that you can lower your room temp.

My main question was/is whats the best way in thailand to blow colder air into a non AC room.

I'm not sure yet, currently working on the burglar alarm system. My original idea is to draw the air in using a simple cooker extractor fan using small ducts at lower level. Can't let on too much, I think I'm on to something NASSA would be proud of.

I would remove all the lower growth on the main stem and cut the three tips back 2/3. Where did you buy them? Do you know what cultivar they are?

At last, thanks Shawn0001.

I got 3 seeds given by a bloke in the next village, he's gone now and I have no idea what they are.

At last? Your obscure question was answered by ThaiVisa in less than 48 hours, surprisingly quick if you ask me. Apricots being apricots and your question having nothing to do with Thailand besides your tree being here, you might do better on a gardening forum. The RHS is very good. www.mygarden.rhs.org.uk/forums/

Blimey, I said thanks. What's up? Rough night? Your lass on the rag?

Fresh apricots....yum yum!

Weird!

I'm thinking blowing the cool air in at lower level and adding a few extract vents in the ceiling. Anyone ever tried to make a home made water cooled air conditioning system?

here in Thailand i had one built according to my design. it's a regular split unit with an added heat exchanger, water pump and buffer tank. the system is cooled by my pool water, it cools the pool area and heats the pool. but i wouldn't call it "homemade".

i also experimented in my former home (Florida) to use additional evaporation cooling by spraying well water on the condenser and increased the efficiency by ~25%.

by the way... whatever home made cooling ideas i have seen presented on youtube and thaivisa are

So, your saying it might just work?

Anyone?

Interesting stuff. I'm currently working on a similar project at the moment but not ready to post yet. Anyone know if it's possible to cool air sucking it through a PVC pipe placed underwater? What length of pipe? Anyone even tried?

It's 14 months old, about 8 foot tall. I started with 3, 1 got eaten by some insect another dug up by the dogs. I only have this one now but it seems to be doing ok.

We have 2 new street light posts put up 2 weeks ago, no cable or lights fitted yet but they look great.

Hello I have a young apricot tree growing in the garden and was wondering should I nip the growing tips off so it will bush out more or should I just let it grow as it is?

Thanks, Sam.

I can be either way about Tarantino's movies but hateful 8 is very good - somebody in a review described it as a Agnatha Christie western which may give you an idea what it is about .

I did not like Skyfall overall at all - i can normally enjoy action/spy movies of this ilk but this one was well below the others. Just my opinion.

I'm the same, just can't seem to get into the new bond film. Bridge of spy's keeps popping up I'll try that one tonight.

Shutter, scared the trousers off of me.

I even threw up with fright watching this Trailer.

Think I've had to sit through that one before.

English language please. But thanks anyway.

This one a little bit old but if you like Sci-Fi.

Thank you but that's not the kind of thing I'm looking for at all. If that's the best movie you've seen lately sir may I recommend one for you, Legend, far from the truth but a good watch.

Thanks again

Sammychong.

Just think, 114 years ago that film was the latest state of the art cinematic technology.

Just a suggestion, there are loads of free to watch film websites online. Why don`t you do a search in Google for free film channels or websites? There are hundreds and thousands of films to choose from, you`re be spoiled for choice.

I have something better than that and I've watched loads of good movies that's why I'm asking for people's favorites.

Before you get redirected to the right sub forum:

Thanks.

The new James Bond is really good.

The Martian is awesome.

Bridge of spies is very good too, based on a true story to free the U2 pilot that got shoot down over Russia.

Sadly they seems to release a lot of crap movies now, I am therefore watching more TV series now.

I'm going for bond, thanks. I've thought about the Martian but a mate said it was no good, I'll try that tomorrow. Cheers.

Deadpool.

I can't seem to be able to get that.
