As a UI/UX designer by trade, I explore how sustainable and smart technologies impact our lives. And I try to dive deeper into those topics to provide context.
Topics like electric vehicles, solar panels, and renewable energy that is meant to transition the world off of fossil fuels. Smart home technology that can make our homes not only more convenient, but safer and more accessible. Wearable technology that can track our health and save lives. Or how technology might be invading and breaking down the walls of our privacy.
So in short...
Exploring how technology impacts our lives.

Can we have one with propane as the secondary refrigerate? Keeps the flammable part out side and gives to you huge operating envelopes of propane. Heck id be happy with a single stage propane heatpump.
The utility of heat pumps is dependent on the cost of electricity. In Europe, heat pumps have been found to consume too much electricity to be cost effective.
As a publicized civil engineer who has elected for a induction cooktop in thier next home i don't think this video was fare to the benefits of gas cooktops and felt alot like a shill video.
In the leftwing world it doesn’t play a role of many people of their own home. Those regulations and rules creat poverty MOST people in Germany does not of their own home. One major reason is that the government makes it so 4:41 expensive to build a house in Germany. Pursuit of happiness, not so much in Germany. Good for you you have enough money to have a nice house… easy for you to try to force people to build like this.
I think I've heard the same words over and over without actually getting any information. And yes, if you use multiple items to do a job it's going to distribute the workload somewhat equal on all items. But each item costs money, to buy and use. The most efficient system will use different types of gas / refrigerant to transition from one stage to another. But this is not going to be easily reversed, unless the input and output are mechanically reversed while maintaining the cascade. Now the efficiency... ? I think that needs to be calculated at all deltas and in all directions, heating and cooling. How is the cost compared to other systems and conditions? How much does this cost?
I've always believed hydrogen is the way to go. However the current state of R&D is equivalent to battery technology from the 1970's. Lead acid batteries were the only real form of storing large capacity of power, but they were heavy & bulky. With the advent of lithium (& others), battery storage has become more viable. But we still have an issue. The recycling of batteries leave us with a black goo of chemicals we cannot use and are harmful to the environment. So we've replaced one problem with another. The adoption of hydrogen is still a long way off, but with R&D such as this we can make it a cleaner & more viable alternative.
If it only reaches 40°C then that water is nowhere Safe, similar issue exists with Heatpumps. The Energy savings in ideal conditions don't matter as you will rarely ever operate in those conditions for any length of time and even if you were you'd need to come up with 15°C-20°C to keep the Water safe for Human use.
People have been cooking for thousands of years, with wood, coal, peet and for some time now, gas. Its idiotic to think that cooking can in any way affect the climate, not even counting the fact that climate alarmists have been lying and flip-flopping their claims since at least the 50's, with no real evidence other than computer models that have been dubunked. And to close it off, gas will ALWAYS be better than electric for the simple reason that during inclement weather, when your power is off, if you have gas, you can still cook, if not, well, i guess youll starve.
I will be constructing a new home and i have already planned for installing induction cooking. I will also get the entire rooftop covered with solar panels. As per my calculations, i will get the full month cooking + travel through electric cars + rest of the power bill for free and some additional refund from the utility company for supplying my spare solar generation to the grid. This entire setup is expected to get even within three years. After that it is pure income. And oh yeah... Induction cooking is so rapid that i can't stop marveling whenever i use the one i have currently. It is just a single "burner" cooktop bought more for curiosity value than real need.
How about counting money with their weight while they are sitting in major banks around the world as some kinds of analog state computation of the economy of the US?!!
I wouldn't go with Tesla. They haven't made improvements to the product or the installation. Also, it has to be done all at once with the roof. Now I rent, but my family and friends still ask...which one would you do? I like the fact you can add solar panels and batteries as a long-term project. Have 2nd hand panels in less sun areas or for winter. IF they break then your not out the money.
I recently went up to upstate New York to visit family friends etc. and see the eclipse. There's one very interesting thing for years many years everybody said you can't have Solar in New York snow etc. the weird thing is I saw so so so so so many solar panels. It's a shame they just don't work up there! < sarcasm.
Last February, I switched out my 17 year old gas furnace for a heat pump. Feb 2023’s gas bill to heat the home: $734 Feb 2024’s electric bill to heat the home: $17 (we have solar panels) Yes, my heat pump was expensive, but I got the maximum tax deduction off of my 2023 owed taxes, resulting in a nice return, and if the past year is any indication of things to come, my home energy cost to heat & cool the home will cost so much less, I should have the heat pump pay for itself in savings in as little as 5-6 years of my math is right.
Wonder if you're getting an influx of comments from a certain group of individuals who believe that green energy is a big scam you know they're grouped in there with flat earth, aliens and etc.
How do you deal with a delay of one early stage material, would that stop the whole factory?? How many houses can be done at one time - one factory vs multiple building sites? Agree efficient but is it faster ?
Que traducción tan desagradable. Es preferible ver el video en el original en inglés. El vídeo es informativo y pertinente. Está bien elaborado y presentado.
Speaking about Native, the video's sponsor: "You'll be able to recognize everything on the ingredients list" - Sure, everyone recognizes ingredients such as Caprylic/Capric Triglyceride, Ozekerite, and Lactobacillus Acidophilus.
Hvac design engineer's 3c: pretty cool, but as you said a HP system is expensive to begin with. Adding complexity with 3xcompressors,heat exchangers and reversible valves pretty much prices this out of the market. Natural gas is still 3x cheaper than electricity and majority of the market is 100% happy with systems working reliably between - 5 and 105F. When you're developing a heatpump for - 30F your market is limited to Canadian prairies and Siberia. I wish the guys all the best, but it appears they will stay in the garage.
Easiest way to describe it is a bucket chain on stairs. You can't lift a bucket from the ground floor to the third floor as one person, no matter where you stand, because you can only reach so far up above or down below your current level. But with multiple people all on different steps, you can lift the bucket up or pass it down, as long as the two neighboring people share a certain height where both can reach.
Is A tank of pressurized gas not a form of Energy storage on its own? With the right type of docking device on a machine, like a little mill that spins with released gas, it definitely is a battery
Fabrication methods might lead to different energy capture rates so that lower yields last much longer while higher yields have correspondingly shorter life cycles, offering a range of costs to fit different markets.
Won't ever warmer winters and warmer summers offer both ultra low cost water heating and hot air cooking at ever higher COP. The output is colder air as heat is scavanged from this warm air. The big problem is heat pumps need well insulated homes, well insulated plumbing to keep the heat in the pipes and tanks the summer and reverse in the winter
Some interesting workbeing done on industrial use high temperature heat pumps. What texas showed that no power equals no heat pump unless you have solar
it's crypto advertise... there are low of phisics that for now... no one break.. And this 'new' heat pump isn't new at all. Also.. COP 3.5 is v. low for modern heat pump. IDK in USA you don't have better heat pumps or what? In Europe COP around 4.5 it's a standard.
talking about rooftop wind power... The Quonset hut is a popular farm building in my area. Imagine a semicircular shed that the wall bottom edge does not come to vertical where it touches the ground. I would love to do a ridgeline HAWT on the top of mine. all wind that hits it is forced up and over the building. has anyone seen this before?
They should build cascading heat pump technology into a 110/120 & 220/240 volt line of heat pump window units. When the cost comes down. Would greatly reduce installation cost & eliminate ductwork, and the inefficiency of pumping thru ductwork. Plus many houses, ours included, don't have & can't accept ductwork. So window units are the only thing possible. Also, multiple units introduce heating/cooling redundancy, which eliminates one central point of failure. You can just put fans in doorways till any failed window unit gets repaired/replaced.
I would buy a window-mounted heat pump in a second, if I was confident it would be reliable, and if it were affordable. (I can afford an expensive window A/C unit, but heatpump stuff can be really expensive, and limited supply will keep the price high while the manufacturers gradually increase their production capacity... but i really really hope all that will happen soon, and is happening right now!)
@@Wordsmiths There are numerous "1 way" DC inverter window heat pumps right now. But they only cool, and do not heat the house. I don't understand why the OEMs didn't just start with a full technology transfer of the DC minisplit technology into a unit that goes in the window instead of through the wall, in the first. It's something I thought of minutes after first hearing of DC minisplits about 15 years ago. There's no technical reason why window unit versions of DC minisplits didn't exist from day one. It's literally the exact same machine, in a different shape/configuration. It would be more expensive than the traditional window units of course, but mass production would bring the cost down.
