At the same time, should require that all monopolies WRT networking, by state and feds be dropped. No federal, state, or local law shall be allowed to force a network monopoly. IOW, it is time to allow real competition to take hold.
Google should approach MS, Apple, Facebook, and Netflix and suggest that they invest into Google Fiber. At that point, rename it to American FIber and then push this all around America. Seriously, if all of these companies simply invested into this and focused on any of the places in which telcos were screwing over others (ok, all of America), then it would solve a LOT.
Seriously, far too many of these companies have NOT been really vetted for what they really contribute, esp those in China.
What is needed are satellites to monitor the globe and record CO2 flow IN and OUT of a region. That will actually allow a better check on things.
well first off, Germany is a different area than America is.
Your temps are fairly mild. I grew up on ill/wisc border where we saw temps of -40C up to 40C (and that did not include the humidity; uggh). So, to HVAC an OLDER home that has poor insulation, you either spend 50-100K re-doing the insulation, OR you spend maybe 10K on windows/insulation, and then switch to decent amount of geo-thermal units. Some of these places will take 10-15 kw of HVAC. Even by your prices, that will be EXPENSIVE. Heck, according to your link that is about 20K euros JUST FOR THE WELLS, not including the rest of the equipment.
Sad to say, our equipment currently is not competitive, but I think that it is about to change in the same way that solar did. That is what I am counting on with dandilion.
none. This is heat that is in the ground and works its way upwards. By storing heat in the summer, and then pulling it back out in the winter, it MIGHT see a slight lowering of the ground temp over a 50 year period, though that is doubtful. In addition, it would have to be with homes stacked one on top of the other.
First off, I live in Colorado.
And Like you, I have been dealing with geothermal for a LONG time.
Why? Because it is very efficient and cheap to run. However, I have heard of these costing up to $50,000 in the Denver Basin. Namely in the city here in small yards/large house. And yes, we have California style building here.
Dandilions approach is not the small size, but the way that they drill it. They spent a lot of time trying to come up with a cheap way to drill. It appears that they combined drilling with impact. IOW, they are focused on the drilling.
Now, geo-thermal HVAC is all about moving heat between the ground to the house. Generally, dirt is an insulator. Some of it, such as clay, conducts heat nicely. As such, most companies have different strategies on how to do this. Some will dig trenches 3-4 meters down and then lay horizontal piping. Ok if you have a large yard. Others will drop a couple of pipes into ground water and then open loop it from there (horrible idea; raises water temp and encourages growth). Then the closed loop wells involve 2 different approachs; dig multiple wells(2-10 of these) down to say 300' OR dig just 2 wells DEEP;
Starting new wells is actually expensive. As such, dandi has apparently chosen to limit the wells to 2 of them and simply dig deeper/faster.
You mention about the heat pumps, and basically imply that these are bad. The answer it that these are needed to actually shift heat. For example, here in the west, pulling 55F out of the ground does not heat a house up to 68/72F. Far too many of the cheap ones go out. So, you need DECENT ones. Dandilion will apparently use water furnace 5 series, which several of them are well known for good service. Neither cheap,nor expensive. But once geo-thermal really starts moving foward, bet on it that these HPs will drop in price.
BUT, the real issue is that the local contractors really stick it to the retrofits. HORRIBLE prices. I mean horrible. They talk 30-50K in this region. That is just plain crazy. I will say that adding geothermal while constructing a new home is the right way to go, but, few builders do it. Oddly, it can be done for about 15K, even down to 10K, depending on the situation.
Now,if these dandi can do it at 20-25K ALWAYS, then they are doing great and will make major changes to America. COmbined with a small solar set-up, and some decent insulation on a home, this is IDEAL.
Ground-sourced HP replaces heating AND AC. With most homes in America, we pay a great deal more for cooling than heating. In large part, that is because AC is so inefficient, it requires much larger ondemand systems for the summer.
If all homes had ground-sourced HP then electric demand for HVAC would change very minor over the seasons.
Not quite. It is a close look, not open loop. Iow, they do not extract water from the ground to get the heat, just exchange heat within the pipe the way a normal air-sourced HP would do.
Not so. U can install a geothermal HP to a poorly insulated house with no problem, and it will have it just fine iff you design it right. Basically, it requires a much larger unit with more holes drilled. Iow, u can put the money into inexpensive insulation, OR into relatively expensive HVAC.
So, u are better off having decent insulation, combined with a properly sized geothermal HP.
Actually, the reason for not using heat pumps for heating was that air-sourced HP was cheap, but inefficient in most parts of the nation, while ground-sourced is expensive, but extremely efficient. However, an AC unit is nothing more than a one way air-sourced HP , so is very inefficient when pumping heat up a 30-40f gradient (72f to 102f). But if pumping it down from 72 F to 62f, it is dirt cheap. Likewise, come winter, pumping heat from 58F to 68F is again dirt cheap with even a basic heat pump.
And that is fine. Do not show the jury on the camera. That is why I suggested that the camera should be court controlled. It can even allow for such things as masking voices, or even masking the witnesses, PRIOR to outing the video.
BUT, it is only right that we get to see these.
well, AP will be here before 2022. In fact, Tesla's AP should be level 5 rated within a year. Then others will take time. Most likely, the Germans and Americans will end up buying either Apple or Google's AP who appears to be superior to all except for Tesla.
Seriously, we should have the right to record all courts, in particular, the media should. If the judge is worried about harassment, then simply set aside several cameras in the room, and make the take available to the media and public.
yes, but my point stands. On NEW homes, values are known. For example, values on incandescent lights can be made for the extra heat they produce. OTOH, LED lights does not impact the HVAC by a noticeable amount.
In the end, because builders are allowed to decide HOW to equip a home, with expensive solar, they will likely insulate more, use geo-thermal HVAC, and then a small amount of solar. Quick and easy.
does not matter. If they can give a LIMITED time subsidy to kick start it, great. If not, so be it. BUT, better, at this time, to subsidize storage, then production.
Just the opposite.
By having CA focusing their subsidies on STORAGE and not on generation, this will enable buildings to buy cheap energy, or save their own.
At the same time, by requiring unsubsidized on-site AE, it will encourage builders to put in more insulation, and switch to geo-thermal HVAC.
First off, it is simple calculations that is done by the drafting software. Nothing difficult to figure the BTUs needed for heating/cooling a home. From there, you plug in the units used for HVAC and trivial to figure out the real energy used.
Note that with this approach builders can choose to add lots of AE, increase insulation, go with efficient HAVC such as geo-thermal, or a combination of the above. With this approach, the costs of energy for a building nearly goes away. The reason is that HVAC is about 60% of the energy costs.
Fuel Cells are just not cost effective at this time. According to NREL, they will be, around 2025. Until then, they are a joke.
OTOH, excess electricity can and should be stored in batteries, EVs, even weights that slide down the side of a mountain, or simply thermal. The later would be IDEAL at any manufacturing site that is dealing with high temps.
Seriously, they should instead focus on subsidies for energy storage.
As to solar, they should simply require that all new buildings of 5 stories and less, have enough on-site AE to equal or exceed the average monthly energy used of the HVAC.

Then Google would spin off Google fiber, and have the other tech Giants invest into them as well to run around installing fiber throughout America.
Google should approach MS, Apple, Facebook, and Netflix and suggest that they invest into Google Fiber. At that point, rename it to American FIber and then push this all around America.

They alone account for 25% of all emissions. Scary.

Seriously, in the future, we may wish to require AP equipped cars for elderly, as well as those with a DUI.
