Goodbye? - I don't know if I can keep doing this.
The title says it. Is this something, I tried and have to move on from? I enjoy doing it, but is it economically and socially viable?
I'm really curious to learn about your thoughts on this.

I’ve only come across your videos today and subscribed, then saw your most recent message about taking a sabbatical or reorganization of priorities. Totally understandable, I was a UA-camr in the early days and had done some podcasts, so I can relate, it’s very time consuming and takes a toll on your personal “free” time But, you didn’t fail nor disappoint anyone, maybe you didn’t meet your personal expectations which might not have been realistic (weekly is....weekly, a big commitment of time) you grew and learned, no lesson in life is failure or waste, it’s an opportunity to do it differently next time. And there will be a next time, if not in this iteration perhaps in a different approach, but your efforts are well delivered and appreciated. I will request your professional advice within short time. Thank you, and enjoy your family/personal time 😊
Thank you for your kind words and understanding! 🙏
is this able to operate at real cold temperatures (-6C and below)? as i remember as a former ac ford engineer you can not turn on the system at -6C because condenser simply freeze and can leak.....In this system you will be blowing -6C outside cold air to the already cold outside heat exchanger (condenser in ICE cars) so I am not pretty sure if this think can support it
Hi Alex, Thank you for sharing. There has been significant technical progress in the recent years on the temperature range of cold climate heat pumps. "A study from Oxford University and the Regulatory Assistance Project used data from 7 field studies across North America, Asia, and Europe which shows that heat pumps are 2 to 3 times as efficient as combustion or resistive electric heating technology, even in temperatures well below 0°C (32º F). In fact they perform significantly better than their fossil fuel-based competitors even in temperatures approaching -30°C (-22º F)." See Cleantechnica for more information: cleantechnica.com/2024/01/22/why-heat-pumps-are-essential-for-evs-when-the-weather-is-cold/ ..."In 2021, Tesla improved the Model Y by adding a new heat pump that translated to a 10% improvement in efficiency." I hope this helps. Thank you! Katha
@@NetZeroTech thank you very much :) it is always good to keep updated
You are welcome. Glad to meet you here. Katha
Wow, sorry to hear that you are not still contributing. I always found your videos, intelligent, interesting, well researched, and factual. Enjoy your time with your family. That is always time well spent. I wish you all the best in your future endeavors. 😢😂😊
Jörg, Thank you so much for leaving a comment and thinking about me. I really appreciate you. I hope you have been well! I think I will continue in one way or another. I just needed a break. So many absurdly funny things happened in my life in the past couple years. I feel like it might be of value for others to share and entertain. I am concerned about the political situation and mentality in the US these days. While every country has something in its history to be ashamed of, I grew up with one of the worst and most recent things to be shamed about in a country's history. History has shown that people look for extreme measures in times of crisis. What we have in democracy and freedom in the US today is not a given and it takes effort to sustain. Thank you again for your comment and the taking time to think about my corner of the world. Warm regards, Katharina
Great video as always! Can't wait to update my HVAC to heat pump. Wish ground source wasn't so crazy expensive
Awesome! I'd be curious to learn how that goes. It feels really good to have made the step and live in a more sustainable home. Enjoy! 😀 Katha

🎉 🎊 🥳 Thanks for leaving a comment. 😀 Katha
I admire your honesty. Keep to your priorities. No one can gainsay that. Love your work. Still a subscriber.
Thank you! I appreciate that. I enjoy creating videos. However, it is indeed a matter of priorities at times. 🙏 😀 🚀
It seems clear that she has reeding the script
Yes, I write a script before I record. This is to respect your time and help you get the most value out of the videos. This is great feedback. I think, while being prepared is good, it still needs to come across more authentic and shouldn't seem like I'm reading a script. The daily show has done that to perfection. I'm still working on it. Thank you!
Yellow teeth
Hello! I just saw one of your videos and then this one.... I didnt even know you existed! Now Im very glad I do! =) Thanks for being so real and bringing such good quality content to the web. I really appreciate you people who are trying to help others solve their stuff =D I think you might want to try using AI for some stuff, Im no expert but, nowadays it can do incredible stuff, and a lot in graphic design, video and animation too. So, maybe you´ll find new tools to allow you to be more practical. So well, nice to have found you, and way to go! whatever you choose to do, keep up the love and the good mood!! Cheers from Morocco!
Hi Alejandro! I'm very excited to hear from you! Thank you for leaving this comment. These are great ideas! :-) Warm greetings to Marocco from Colorado! Katharina
Lmao. Says this is not a political video....immediately turns political.
Thanks for the feedback.
you make it seem like this is a brand new tech, but it's been used in homes for centuries
Yes, I agree. The only difference is that today the systems are safer and more cost-effective.
As someone living in England but built houses in Canada I prefer forced air for the benefit of drying the air and filtering of the air to reduce the amount of dust, mould and allergens. My houses had a HEPA electronic air filter and a well engineered modern system is very quietly. Nothing makes me laugh more than an English home or building with a window open in the winter.
That's so interesting! Thank you for sharing! 🚀
Very short and insightful! I'm living half across the globe and just dipping toes in the water. I'd first show this to anyone who confuses about ERV and HVAC. Thanks for the great content!
You are very welcome! 🙏 Seeing people interested in learning about ERV and HVAC is exciting! Greetings half across the globe.
the lady at 1:55 looks traumatized.
Yes, you are right. Strange.
The sound qulality makes this unwatchable just fyi
Yes, apologies. It's one of my earlier videos. I should do another recording, as the content is still up to date. Thank you!
Yes! It's one of the early ones. Appreciate the feedback.
Whatever you do, success! Please, leave the videos on youtube, they help a lot of people that you have never met. Thanks! If you do find the time for another video, maybe on how to install a cheap air to air heat pump, DIY. Many people do not have the money for a complete heating system, an air to air HP can help for those months that are not to cold to cut the costs for heating. Thanks again for all the great videos!

Many of the challenges you’ve faced, as an engaged, independent creative person- all of director, producer, writer, editor and front-office staff/ marketing- are things I think of often, when viewing various manufacturing and materials science/ construction videos. I’ve seen what you do but would like to say that it’s your remarkable sincerity and kind personality that has made a lasting impact on me, once I’ve reflected on the time spent watching. Therefore, I’m happy to see you stepping back, and looking to take care of your family, to tend to your own needs and make time for ensuring your relationships are being honored appropriately. I daydream that, once I win the lottery jackpot, I may hire some of the more personable builder-creators or, even, observers of the trades spaces, like the guy who started Tumbleweed Tiny House Company, back when I had become enamored with the idea, for my own personal lifestyle. As I’ve continued my obsession to extend into the idea of a manufacturing enterprise, it’s the kindhearted and passionate, creative and thoughtful people that I’d hope to secure as consultants on the tiny house and built-in-place project. Sooner- rather than later- I hope to be able to reach out, with some lottery money and a consulting opportunity! Thanks for all the informative and engaging programming, over the last year or so- you’ve inspired and helped me understand the need for a thorough approach to building value. Take Care 🙏🏼
I think you are exactly correct.....no one I know has looked back and said I wish I had of worked more and sacrificed more time away from family. I'm usually a pretty good judge of character and you are a great person! And trust me I know your type, you are by far your toughest critic. How about you take a break, spend some time with your family and doing some flipping or other activity without a camera. If you want to continue posting videos you can make your "I'm back" debut video! Best wishes
Thank you, Michael. That’s very kind! I really appreciate it! 🙏 I might do that.
Your videos are good. Have a good life.
Thank you! 🙏
Thinking of the long term is always a good idea. Take your time.
Agreed. Will do! Thank you! 🙏
Hi, It’s good to identify this early and take your time for the most needed things. Learn editing slowly and change the video more to interview format. You did great job. Be proud of it. Continue to Sontheim at a pace that works for you and without financial expectations by self editing. You will love it even more.
Thank you very much! Great advice! 🙏
We’ll be here
Thank you! 🙏
All good - you can always make make a comeback!
There‘s an idea! 💡 Thank you! 🙏
Thanks for making the effort to deliver real information. Humanity has very little time to stop the progress of the climate crisis that we are in. It seems that our governments have been bought by the fossil fuel companies who don't care that our children may lose civilization because of the bad choices they are making now. Thanks again for trying to make a difference.
Well that just breaks my heart to see you so sad 😢 take care of yourself and those that you love first. UA-cam can wait ! Maybe you can try a different style of videos that doesn't require as much post production work . Honestly i watch your channel for the very informative content - not for fancy editing and visual effects
Sorry to hear that. That is great and valuable feedback. That‘s a good idea. Thank you! I might try that. 🙏
If net zero is impossible, we are going to be extinct. Tipping points will make the earth uninhabitable. Civilization will collapse and the food and energy system will end. You can expect 6 degrees of warming or more and sea level rise of 70 meters.
Always glad to see you have more content! A thought about Air to Water heat pumps. In hotter and/or wetter climates, might an indoor heat pump that moves heat from the air into the water also provide a side benefit of cooling and dehumidifying the space it’s in? This seems like an under reported side benefit of Heat pump Water Heaters, though I wonder what the effect size would be??? Just a thought for a video idea…
Hi Michael, Thank you! I appreciate it! I have been trying to do weekly videos on Saturdays, but haven't quite gotten to consistency... even with the support of a great editor. I'll try to keep going. More about that in the next video. I think you are spot on with that video subject. I have always been skeptical about heat pump water heaters. But there are many people finding them quite efficient. I want to dig deeper there. Stay tuned. 😃
@@NetZeroTech awesome! Hang in there, I hear it’s hardest at the beginning, you can do it!

Glad it was useful! Any time! I think my editor did a great job. Unfortunately, it's not economically viable for me to keep him for now. More about that in the next video.... I hope you have been well!?
@NetZeroTech yes I have been well and hope that you have been too. Your production values have been outstanding! And I hope that your house flipping project is going well 😊
I'll pass that on to the editor. Thank you! Yes, I think the fix and flip will be good. We'll see. :-)

Geothermal is best. Use the earth to heat and cool your home for free
Agreed. 😀 In Sweden, every 5th household has geothermal. Air-to-water is a good compromise to reduce the upfront costs. With a good air-to-water installation, you can save up to 30% on utilities and slash emissions by up to 90%. Thank you for sharing your thoughts. 🙏

You could just remove the copper and other impurities from the recycled steel, but it's not economically viable to do so?
Researchers have found a new way to electrochemically remove copper from steel and reduce impurities. If it’s economically viable it will take decades to be implemented. It might be implemented in new plants but possibly too expensive to retrofit existing plants. We’ll see. 🙂
You can rip apart alloys by diluting the metal in acid and applying certain voltages. I've seen it done with brass. But there's absolutely no way it can be done on a large scale.
@@laszu7137 Thank you for sharing! 🙂
It's nice that they are starting to use hydrogen for steel production instead of fossil fuels. It's just too bad that 99 % of hydrogen is produced using fossil fuels, it's very expensive to produce, and storage and transportation are a logistical nightmare.
Yes, That’s why I invested in and worked for a green hydrogen startup. It can be done fossil-free. It mostly depends on the electricity price from renewables how economically viable green hydrogen is.
Nice video as usual.
Thank you! 😀
Green heat provided by hydrogen could be a boon, as well.
Green hydrogen is typically too expensive for heat and there are some infrastructural challenges. Can use electricity like the electric arc furnace and have that come from renewables. Thank you!🙏
@@NetZeroTech Here is a start up to check out. Hopefully, enough residual streams of electricity can be harnessed cheaply to make it work. greeniron.se/
Green heat form Hydrogen? You need to research how Hydrogen is manufactured.
@@darcymandryk1785 Could be green hydrogen, but that's only economically viable where electricity from renewables is inexpensive enough.

I live in the united states and I drive 80 miles daily at a minimum. I definitely need a range in the low 300s to get by especially when it gets cold.
