Finished the heating duct. Conclusion, do not move heat by air from a stove. It goes too slowly.. I was disappointed on the heat gain. If you ever want to move heat, sigh, use water for more heatcontent to be moved.

I read your projects and see much ambition. Although it cost a lot of time, keep up the good work!

Well, I was working on laying a 4in isolated flexible airpipe to go from the first floor, through an airshaft aside the chimney down to the first floor to heat the ground floor with the stove on the first.floor (our living and bed room). Bought a thermal camera to see results (and winter optimization) but nothing happened. Turned out the pipe had ruptured inside the air duct. Now have to redo the work... At least I do not have to finish it tomorrow

Nice question to ask. As usual too many projects to cover in this short time 😁.

Closing the lower part of the serre for the winter upcoming. Creating a hatch out of too small hinges but these were available. Also made a rack under there to place the double winter windows which are exchanged in the winter for muskito windows from the summer. Working with wood is very fun.

I am also working on making a small duct to displace heat generated by stove on the first floor to the groundfloor. Have some difficulties finding a right thermostat that turns on over a certain temperature. Unfortunately photo upload is not working for me ATM otherwise I would have shared.

Good tip @Mike D. I want to make lightpoints for my house and sauna house in near future as it's get autumn and winter here. So I will now look for a yellow glass screen for these lights. The yellow I also like more for the warmth. Hope I have bought lights with good CRI which have larger color frequency range and give more natural yellow as result

It was a nice read although a bit short. I wanted to continue. A very good sign, thanks

Good words, schmorpel. You transcribed my thought exactly as is ;P. Hereby a imaginary photo from also the same type of sunflower I saw today in our garden, aiming towards the north? ( I live in northern hemisphere though).

A bit of hoax story to be honest. Two questions come to mind. How is the police able to access camera and microphone? As far as my knowlegde the security of the OS on the phone is quite tight. Maybe apple or Google have built in a backdoor but 5 years ago they were quite resistive towards governments. Also the legislation of EU is quite tight on privacy where cameras are not allowed to be used for tracking individuals. So police is not able to use the information in court.

 

We drink a lot of milk and I have been collecting these bricks with the idea that there would be a usable function like isolation. But I slowly come back from that plan. the plastic inside will breakdown after a while I would think and there is no structural support of these packages. If I keep it empty, mice can nestle in it and filling with foam prevents from curing...

I am a bit out of ideas. Now i am thinking of using as insulation but then as a flat package. It will require only more milk drinking though 😅. maybe you have some ideas to reuse these cartons?

 

I have been thinking on how to claim every energy that comes on my plot. Technology goes more and more into harvesting the smaller left over energy. Ive seen examples in the Netherlands where startups try to get energy from a chip (I have been thinking on how to claim every energy that comes on my plot. Technology goes more and more into harvesting the smaller left over energy. Ive seen examples in the Netherlands where startups try to get energy from a chip (http://www.nowi-energy.com, https://memsys.nl) and a transparent solar panel layer on windows etc. Here in Lithuania sometimes the whole day has an overcast sky and that is the solar energy that we are getting. I know that with heavy overcast days a standard solar panels output can be as low as 10%. So a 5kWp can generate instead of 3.75kW produce only a meager 370W. My question to you, arent there other solar technologies that are adjusted to this overcast circumstances? So to gain more efficiency from diffuse lighting or from frequencies that can pierce the clouds more (like infrared spectrum)?

Some sunday morning pondering....

The video was nicely made. So much effort and material to gain views only... But nicely made with the shaking when starting the generator and then a sound taking over. the constant rpm with an angle grind turning on was unfortunately not well implemented. Maybe just enough flaws implemented to keep it at the satire level.

 

Would it not be nice to have an inverter (2kw) which is off the grid that can work by having a very small buffer (1 kwh) to power applications that can work intermittent. So when the sun goes away, the applications (such as a pump or fan) work for one hour more and then stops. Like a UPS.

I work for a company that uses small solar pumps for small holder farmers and these pumps do not have batteries. So when the sun is away, the pump simply stops working and continues to operate when the sun is back.

I would like something like that for my shed. My question is this, does anyone knows the correct terminology for such an inverter and or do you know a brand as an example that can do this?

Very interesting but compost has some use. I can see we can use water but co2, what to do with that?
