In Germany our house runs with a similar system that uses air instead of the ground because we are living in a water reserve area. It is called air-water-pum. These systems function like a fridge but the other way around and only use electricity. The good thing is that the electricity you use for the heater is cheaper thanks to substitutions by the state.
Lots of newly build homes decide for these systems because if you get a heating system that is run by gas you would have to put solar panels on your rooftop and sell the electricity for a cheap price - if you like it or not.
We will put some solar plates on the rooftop, too, so we can run as self-sufficient as possible in the near future.
Love to see how the market is changing and the possibilities that you now have when it comes to going green.
I’ve been SCREAMING for the state of Michigan to use this system on a larger scale!
I didn't know people listen to those who scream.
University of Michigan is on it.
Also they are doing a groungbreaking new hydropower for small speed water, called Vortex Hydro Energy, which can even work in the small streams of Michigan and many other nations worldwide.
It cost thousands to put this in..the energy companies need to use this instead of us. Then we buy the electricity. Not HVAC
my parents installed one when they built their house; it works fine for 16 years now;
one compressor died recently and had to be exchanged. 600 EUR, but that´s about it. not even adjustments or calibration needed.
@@smartgorilla Dandelion Energy (her company) claim to be able to do it for $30'000 and let homeowners pay off the costs over twenty years at $115 / month.
I'm Kenyan and I never knew the process of how the gas lines work in the US but in Kenya we use Geothermal and other renewable energy sources to help the planet : )
This has been around for years, and in my 15 years of HVAC in multiple states like Idaho, Oregon, North Dakota ive seen about 3 installed personally very few ever ask about it but when they do they see the amount of work that goes with it and the price and run away. Lol
How much does it cost upfront? Is it cheaper long term when compared to fossil fuels?
in Denmark, we just burn our trash, filter it so it's safe for the environment, and heat up water, that we flow to houses so we have floor heating
Do you have some facility at home to burn your trash?
@@ShaoYuanYuan no, theres a big trash station that picks up our trash, sorts it and burn what they can filter out the bad stuff, so its just water and a little co2 coming out of the pipes. and then they heat up water when burning the trash and send it out in big pipes. so we have floor heating and hot water for showers like that. aka we have nearly no landfills
Incinerators are incredibly bad for the environment I understand and human health. Breaks the circular economy and releases toxic chemicals as well as greenhouse gases (can these really all be captured as stated?).
Incredibly greedy, resources can no longer be recycled for future generations.
People living near have much higher rates of health issues. I will not go into the details but they can be found. I would recomend reading about the disadvantages of incinerators. Burning is generally not a good idea I believe.
@@dasbcutpaste6473 they are not Incinerators, everything is sorted and only what can be burned cleanly is put in the ovens. its much better for the enviroment then any other solution. but things that can be resued like old funiture and speakers, books you name it is sold in a store besides with a really good price, the speakers im using right now are from there. but paper and plastics are also reused. and yeah the filters are really good i have been on school trips there before and i live close to it we have some of the cleanest air in the world :) hope it helps
side note some of them are starting to use carbon capture too, the one in copenhagen will capture 500.000tons a year. it also gives us green heating and hot water
Nah, der er stadig mange problemer med det. At brænde ting af er jo aldrig det mest bæredygtige. Og at have det anlæg giver jo kun mening så længe vi producerer nok affald til det - men idealet er jo at vi holder op med at producere affald!
Ground based heat pumps are unaffordable still, and the consumer cannot do anything about it. Depending on cost of energy and usage i'll make a rough guess (based on my bills and cost of installation here), it'll be an average of 25yrs before you could break even on the investment. Older homes will require further investment from the consumer to fully insulate the home to allow the heat pumps to keep up. It's only really a good idea if the house builders integrate these in to new builds.
It depends. Its just fine here in Finland. Our house from 1953 has had "enough" insulation (only packed sawdust!) from the start and even air-to-water heatpump is enough. There were a rumor that our area would not accept heat wells (we have lot of clean drinkable ground water, so they think that it would be compromised when drilling through it), so we got that air-to-water heat pump instead. After that, several neighbors have installed geothermal heat pumps, both in the new houses and to as old as ours. For some reason those are mostly drilled holes (usually around 100 meters) and not just plastic pipes laid under couple meters of ground here. There's a difference if you dig out all of your back yard for the pipe field or just get the drilling crew and go directly down and make a mess for 10-20 square meters, with mostly water.
Works well in certain applications but you are spot on for the up front cost. Thats why gas is so cheap because it is on your utility bill forever and not your mortgage. Same as electric cars, upfront costs. Those things are changing though as new builds generally have airconditioning so the air to air component is already there. I think the triple threat for new-builds are solar, battery buffer and air to air heat pump. I have some neighbours that are all in and their payback is in the 10 year sweet spot. I am optimistic we are on a new S curve on this as its economical.
Common problem with the green technology
@@zUJ7EjVD This is how capitalism flourishes though. People do want sustainable energy, so the market is there, and is potentially cheaper once the technology is there. But the consumer can't be the driver for investment in technology as there are too many issues in the world for the consumer to foot the cost, so it's up to the companies to provide the investment because they will see the return in investment.
If you're happy to sacrifice your money to slow down climate change that's fine, but most people will not, especially given the costs of the technology mentioned in the video. I simply cannot afford ground heat pump installation, whether i wanted to or not.
@@lpdirv 10 years i could afford i think. Any more and it sits uneasy with me due to unknowing if i will move house after that time, with no guarantee on getting that investment back sadly. Impossible to say if a better technology could be available then, and at a cheaper cost, so pushing that original investment cost on the property value i remain sceptical. But it's very good that there are examples of heatpumps working financially for people.
So weird, when did TEDTalk became a commercial space for advertisement. I’m totally supportive of her idea, but it just doesn’t sound like a talk, it sounds like more an advertisement…Hmmmm, interesting! 🤨 🧐
Which makes it very hard to give it to thumbs up or down.
Yes this is very disappointing. They should start videos with this is a ad statement. (By law or consumer force)
It’s an Ad for sure but it is informative and I’m curious to learn more about the alternative. I agree though it wasn’t as fulfilling as other Ted talks
Yeah, but at least the name of the company is not mentioned or shown.
I got that feeling too. Lame lol. Didn't even mention geothermal energy until like 3 mins in lol.
@@g.o.6379 it’s not informative at all - she didn’t explain the whole process of what she’s suggesting and its drawbacks. Just watching any other video and reviews on heat pumps gives way more objective information.
It’s the 5 minute, 20 second ad for me
It is also worth to mention heat pumps using air as energy source or the problem of missing insulation.
Greetings from Germany, we get more and more sytems that gain energy from deep soil, ground water or even the air almost down to the freezing point. I personally utilize such electric heatings supported by the heat in the ground. However it usually provides less than 50% of demand, if I am correct
Was this a commercial..? Geo has been around for years
Awesome! Should be spread all over the world 🤩
I do wonder in how far this is possible in big city centers and buildings?
Always think positive and spread positivity
I feel it's important to point out that not all electricity is created cleanly. Some even comes from burning coal. While I completely agree with the process involved in geothermal heating and cooling it is equally important to generate the electricity needed to circulate the desired temperature variance throughout the dwelling cleanly. It isn't as if there aren't any options. Between solar panels and wind turbines there's a good start. If we include more exotic methods we get into gasification of biomass for use in a standard generator set and even as far as LFTR installations. We can even make use of hydrodynamic power for those who live close enough to a stream. It doesn't have to be coal or nuclear power or even a huge dam if we all chip in and do our part. We could have a much better world to live in and leave for our children.
Thank you.
In Europe we have buildings that are hundreds of years old. In Japan houses are often torn down and replaced after a few decades. What do you mean when you say your ground loops will last as long as the homes they are installed under?
Modern pipes are theoretically designed to last hundreds of years so that's not a complete lie
You just renew the stuff periodically. These systems lasts 20-30 years, they are relatively common here in Italy
Amazing!
guys theres this system, hear me out, that I founded a company to take advantage of! it would be REALLY awesome if everyone switched to it right now... (obviously it is a good idea but come on)
there are tons of ted talks like this. this one is just more obvious
What a wonderful world
I need this!

more of an advertisement than a "talk"
The renewable heating system right below your feet starts on 3:30
Also you should stated this is sponsored video. The chick is promoting her company.
So what? Her business is making this world a better place buddy unlike others!!
👍🏼😄
"Let's make a 3:30 intro, then get to the subject for about one and a half minute and then go on with life."
Welcome to youtube 😉
also an AD for something that is not new in any way. Heat pumps have been around for quite some time in Europe. Everyone i know who built a House has considered getting one. Some have actually gotten one. It's definitely not for everyone but in combination with a well insulated passive-house it's amazing.
Heat pumps have the chance to be the next best thing, because they can also cool down the House in the Summer.
Nice video.
Big fan from India🇮🇳
Great talk!! 🥺☺️
very good
Well worth adding
Awright
I would love it if TED Talks could get to the topic, not wait 'til 2/3 of the way through.
Need more detailed explanation for an ordinary person to grab the idea of how to heat a home in a cold area ( Michigan, Alaska, ....) using this methodology. Please help.
Several feet (less than 20) under the ground, the dirt stays relatively warm. I'm not exactly sure how warm, and it provably varies, but lets say 55 degrees F. Then, these pipes work kind of like a refrigerator, but backwards: they cool down that dirt and pump the heat into the building.
The dirt gets warm again from all the other dirt around it (this is where it gets a little fuzzy for me), and so you can keep cooling the dirt year round.
In Alaska, you may have to go deeper than in Nebraska, but the idea should be the same.
@@andrewschmelzer9704 Thank YOU Andrew, for your explanation. Let me contemplate on this. This is a new concept to me. Thanks a bunch.
They have been using this in Northern California Alaska and Washington 30 years ago
@@mikehines3446 I live in West WA state and never heard about this system. This tells how much limitation of me in this technology. But how come it became unpopular. This baffles me. Thank you
now this is an infomercial I'm down with
I ❤️ her !
Thanks TED for many videos like this 🙌🤝
This is a sales pitch for geothermal heat pumps. No mention that electricity is required to operate the heat pump and circulate fluid through the thermal loops. It has its advantages and disadvantages. First cost can be high. Land space to install the loops is also required. Wells can be used but they are also expensive. Not all locations are practical. Also if heating and cooling energy use is not comparable, the loops can heat up or cool down over time causing them to become non functional. Always get an independent cost-payback analysis comparing alternate systems done first.
What a great talk 👌👏💕 I admire this most👏👍
Nice man
I've been in caves in Alaska that go deep Underground the hold a consistent comfortable temperature that was 30 years ago
Very helpful video ❤️❤️❤️❤️✅💯
Nice Tedvertisement
Yeah, except it's really expensive to install and it just saves on hidrocarbons, it doesn t eliminate them. Instead of heating water from 4 degrees celsius in your central heating sistem, you heat water 10-12 degrees, making huge savings in energy but the heat source is the same
I feel like Ralphie when he was duped into decoding an Ovaltine advertisement.
Now TED is into infomercials too?
I think this is being eclipsed by a combination of solar, battery and modern air to air heat pumps. Air to ground is expensive and for the same cost it is possible to go net zero today. Geothermal makes more sense on a larger scale application. Better yet, we can use deep geothermal in an ammonia cycle to produce both power and distributed heating and cooling. Very well summarized and remember, we went from wood to coal to oil to gas and now the shift is to electric. We will be ok, we have smart people and the economics are starting to favour new tech.
Starts at 03:16
Air source heat pumps are a lot simpler aren’t they? Much easier to service than buried pipes right?
Yes. But what about efficiency in both heating and cooling? In the winter one would like to generate some heat from cold air and in summer one would cool it's house with warm air. Sounds counterintuitive to me...
@@Sierra-Whisky Search for “technology connections heat pump” for a clear explanation of heating and cooling homes with air source heat pumps.
During the Texas power outage of 2021, 189 people died - mainly due to the overreliance on an unreliable energy source - renewables. How many people have to die before people priorities reliability?
This is insanely cool.
Absolutely!
Unfortunately less than 1.30 minute of this 5.20 minute talk was actually about this interesting geothermal energy system. :(
@@Sierra-Whisky yeah I sorta hear you? HOWEVER: I think helping people understand how harmful fossil fuels/deep drilling is before selling them on the solution is really important! You don't want pencilling until you realize you're a diabetic.
@@benjaminbutcher of course I fully understand, but what I mean is when you make a video about a subject that isn't well-known among your audience, then take more time to talk about the subject itself. Now only one third of the video was actually about geothermal energy. It's about a week ago that I heard from it for the first time so I'm quite new to the subject. Therefore I got delighted when I saw this TED talk was being published. But after watching it, I thought to myself: what information about geothermal energy did I actually get in these 5 minutes? Close to nothing, which is quite disappointing.
Why is this ad on the TED channel?
A highly efficient system.
Renewable heat, right below your feet

You still need to use electricity and a special equipment (heat pumps that resemble air conditioner system) with some refrigerant in it. Would be nice if such video showed some analysis on it - numbers, comparisons, drawback, etc. Otherwise it sounds very black and white and like someone is trying to sell me something.
I don't see a link to her company.
Dandelion Energy. Will post link separately in case links are banned.

How is geothermal energy "renewable"?
'Renewable' is confusing term. A more accurate word would be 'abundant'.
You can even cool your house by this process

"...A ground-up utility..." I see what you did there
lulz.
I didn't knew that you need just some feet under de ground. I really thought you neeed to dig deep and only some places could use geothermal
Recently a lot of TED talks feel more like advertisements than anything else...
I think that's fine. If idea is good, is good to have an option for people to implement that idea or concept in their everyday life.
A lot of youtube and even the news channels we follow use 'native advertising' and make a report based around a product. All to talk and get people searching more about the object of the article.
Sure, but I'd rather here about it from independent researchers than from the CEO of a company making money from selling and installing those systems...
If we are serious about energy demands, why not make everyone liven in earthen homes? But that would require far greater urban sprawl and thus more vehicles and miles driven and more gallons of gasoline. Why not require passive solar designs in our homes? Broad porches to reduce cooling demand, deciduous trees that shade in the summer and let the sun shine through in the winter
Very cool but I can’t help but feel like I watched an advertisement
My friend has this system and it doesn’t work
And you need under floor heating
@@tinywrasher7923 So, you're saying that my house has not been able to survive last 6 winters with heatpump and old radiators from 1953? It's only -30 degrees celcius for couple nights here in Finland, but -20 degrees is quite normal for some time. Oh, and i have way more problematic air-to-water heatpump, same system would do geo way easier, as the heat source would be steadily at about +5 celcius, instead of -20. And my system also makes hot tap water, so it has to heat the water up to 60 degrees. My radiators manage to keep the house nice and warm with 40 degree water, when there's -30 outside.
Yeah this typically isn’t realistic (yet) to fully power a modern home without subsidies & deep drilling. That said no reason it shouldn’t be part of a more renewable solution, if one gets say 30% from geo, 30% from solar & 40% from the grid it’s not unrealistic if amortized over the life of say, your mortgage.
her eyes makes her face look like a very advanced beautiful humanoid LOL
Nice add...LOL!!
Does her virtual utility company cover the costs of the ground works, retain ownership of the ground loops, and charge home owners to use the loops the way a conventional utility charges for fuel?
No, they offer a financing package that puts you $30'000 in debt to them and pay it off over twenty years (looked them up).
3 and a half minutes till she starts talking about the actual topic. Wow. And the topic is neither in the thumb nail nor in the title. That's click bait.
Is this an advertisement? Do you not know people live in flats and small houses cant support this? I have a very small garden. The HVAC are noisy too. They 15k!!!!!!! Or more and you need to take out all your rads as they aren't warm enough!
Not to confuse the issue with facts but in the US, 60% of the electricity needed to operate the heat pump comes from burning either coal or natural gas.
Only the last 2 minutes is about the topic. I was hoping for a little information, not a screed that we are all aware of. If I didn't already know the problem, I probably wouldn't be concerned with a solution. I guess the title isn't an outright lie, since you get around to some lip-service. Let's call it a con, then.
Holla ❣️
My dear let me recommend you to Dr okeke who can help you out

So lets just use all the steel or aluminium you mean ,steal will just rust how about use sustainable wood theres a plenty it's called a fire place youd probably have to dig a hole a kilometres deep to get the steal you need ? No such thing as sustainable heat
Is this a Ted talk or a commercial for her business?
Every time geothermal energy was tried in central Europe, it resulted in a whole village cracking in half.
This is advertisement ?!?
So TED is now an advertisement machine. Cool, coolcoolcool
TedX has always been. But every good idea is going to have a company behind it, lets be real. Sometimes though, yes, native advertising gets the bills paid for these corporate "nonprofit" type companies. Especially social justice ones, its just income sourcing and many people need to pay bills, even in nonprofits
Great concept, possibly, but a one-sided story delivered by a person with a conflict of interest - that sets off red flags.
now ask her if your neighbours are using the same technology what happens, this is plain advertising, she just doesn't point the problems with geothermal
Pretty disappointing video. Came for the subject title but the first 3/5 of the video is how homes are currently supplied with the following 2/5 being a sales advert
ok, now... Who is paying for it ? I'm not. Thanks.
quite old and nothing new, but feels like a huge ad campaign ... and not a solution.
And these systems can have also a lot of downside if deployed in bigger scales by communities or cities cause here they had caused earthquakes and for all that do not believe that simply do the research.
No insurance company was willing to insure the project with all its risks cause the first time they had rejected to have cause that earthquake but the second time they ran in trouble.
And even in small use cases the truth is that it not always will work out or that you to digg a lot deeper than planned and then the costs will explode for drilling that particular hole needed.
It is simply just one solution among others where you can choose from, some are easier, some are cheaper but at the end it will depend on your preferences and mix or situation. Here we can not sell surplus energy from private wind turbines and solar roofs and then it can make sense to produce hydrogen cause it is a chance to store energy for a longer time at least in a neighbourhoood were all agree to work on a common solution. Batteries can not achieve that and so we use the fuel cell as combination of heating and power generation in the dark cold time.

Would be a more interesting talk if costs, and viability of geothermal were discussed as opposed to 4 minutes bashing the system we have in place. I think everyone who watches TED talks knows that the current system is ruining the planet for our future generations, but this un-informative video is clearly just a chance to create quick content.
You guys heat home??
wtf this is not ted talk this is a fucking commercial !! where are the BAD sides of geo thermal !! THEY EXISTS !!!
more plastic, lol, btw. nice commercial

$$$$$$$$$$$$$
Haha. I'm the 420 veiwer
How will geothermal heat/cool skyscrapers?
You lie 3 times in the first 30 seconds.
1. Canada, a safe country not in conflict is flooded with oil and we would love to export more it to the US.
2. Oil is highly renewable and does not take millions of years to develop.
3. Pipeline are the safest way to transport Oil, but the railways make billions running rail cars of it through towns and cities.
Geothermal is a fantastic renewable resource thst could be used more. Please don't beat oil down to prove your point.
Jesus, these sound effects are so annoying
This isn’t educational in the strictest sense of the word nut poorly veiled marketing.
Sounds nice - but what powers geothermal pumps? Electricity - electricity that must be RELIABLE
