Tales from Dandelion customers: geothermal heating, cooling, and energy independence
Behind every installation of a Dandelion geothermal heating and air conditioning unit is a story. These stories are different for each customer, but each tale involves a notable common factor — a move towards gaining independence from fossil fuels. Here are a couple of stories from Dandelion customers who turned to geothermal solutions, and never looked back.
The Engineer

When software engineer Matthew VanDerlofske came across Dandelion Energy’s heating and air conditioning system, he realized that it was the perfect way to help his family step away from fossil fuels. For VanDerlofske, a key reason behind his adoption of Dandelion’s geothermal solutions is the savings offered by the system.
During the gas spike in 2008 and 2009, the software engineer admitted that his family was budgeting $600 in gas per month for their SUVs alone. They were also spending $1,600 worth of oil per year for heating, on top of 15 megawatts of electricity per year from the grid. Eventually, VanDerlofske and his family realized that it was time to “start weaning ourselves off fossil fuels.”
The family started in 2012, investing $6,700 to have 32 solar panels installed on their roof. They also traded in one of their gas-guzzling SUVs for a Chevy Volt. Later, the family added an additional 24 solar panels, allowing them to produce more power than they consume. The family also acquired a Chevy Bolt, their first all-electric car. VanDerlofske and his wife regarded Dandelion’s geothermal heating and air conditioning system as the next step in their pursuit of energy independence, as it allowed them to get all their heating and air conditioning needs from the ground.
The Environmentalists

Dandelion Energy customers Paul and Joanne Coons have always been passionate about the environment. At one point, Joanne, a high school environmental science teacher, took it upon herself to make her own biodiesel from restaurant waste, which she used on her diesel car. Together with her husband, she also experimented with burning home-brewed biodiesel at home, in order to help offset their house’s $4,500 annual heating cost.
The couple completely embraced the energy-independent lifestyle after they took on the task of renovating a dilapidated, historic house in Clifton Park, NY. The home, which had no buyers due to its condition, was transformed by the couple into one of the most energy-efficient homes in the country. Since then, the house has won several green building awards, and it has become certified as a LEED Platinum and NAHB Certified Green Building Emerald home.
To make their historic home energy independent, the Coons opted to install an array of rooftop and pole-mounted solar panels, which they use to help power the house and charge their Nissan Leaf and Toyota Prius Hybrid. The couple, who also has a reservation for the Tesla Model 3, also opted to have a Dandelion Air unit installed for heating and air conditioning. Referring to their biodiesel-brewing days, Paul stated that ground source heat pumps are the best of both worlds, since “you can heat and cool your home with the power of the sun, and you don’t have to keep fueling the system.”
Ultimately, customers who are already committing to sustainable energy through rooftop solar solutions can’t go wrong with a geothermal heating and air conditioning system. Read more about Dandelion Energy’s geothermal systems here.
Tesla flexed the new features of the Model Y L with a dedicated media event at the company’s Diner on Santa Monica Boulevard in Los Angeles.
The Model Y L is the extended-wheelbase version of the all-electric crossover, which has been voted the best-selling car in the world on three occasions. The vehicle is already rolling off production lines at Gigafactory Texas, and first deliveries are slated to take place later this year.
Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990
Teslarati was invited to the event, but due to some scheduling conflicts, we could not make it to Los Angeles. Instead, we will have our hands on a media unit sometime in August, so we’ll be able to spend some more extended time with the Model Y L.
However, plenty of those who made it to LA shared some cool features that set the Model Y L apart from the Model Y.
Multi-Row Climate Control
Tesla fitted the Model Y L with full climate control on all three rows on the front screen. It can be adjusted by selecting which row you’d like to modify on the right-hand side of the touch screen:

Better Rear Window Visibility
One of the strangest things about the Model Y, especially the Juniper iteration, is the rear window has extremely limited visibility when looking into the rearview mirror.
Tesla has improved upon this with the Model Y L:
This is a drastic difference. https://t.co/wTdhitD5aA pic.twitter.com/z6hFs0Jkss

PowerShare will be included
Model Y L will come with PowerShare in North America, with an 11.5kW output to your home. Tesla said it would require Powerwall 3 for operation.
Wireless Charging Pad
There has been some speculation that Tesla would upgrade the wireless charging pads in the United States, but this is not the case.

Tesla owner fixes common feature complaint with crafty DIY retrofit
Tesla confirmed that it does not come with the cooled pads as the Y L in China does. This is because North America has not adopted Qi charging yet.
Thermal Management Improvements
These improvements in the Model Y L were seen with thermal management:
- Up to 15% faster cabin cooling
- +23% thermal efficiency gained in hot weather, 7 miles of real-world range gained
- 8x more solar energy reflection off of glass roof
- 30% reduction in solar energy entering the cabin
Some of the thermal management improvements in the new Model Y L Premium:
• Up to 15% faster cabin cooling
• Up to 15 min faster cabin cooling in sunny conditions
• +23% thermal efficiency gained in hot weather +7 miles of real-world range gained
• +10 miles recovered after… pic.twitter.com/jZirFWFdtO— Sawyer Merritt (@SawyerMerritt) July 31, 2026

Tesla CEO Elon Musk took to his social media platform X on Thursday night to deny a ridiculous rumor regarding the sale of the company’s Chinese vehicle production plant, Gigafactory Shanghai.
On Thursday, the Wall Street Journal, citing sources familiar with the matter, claimed in a scathing new report that Tesla was exploring a potential sale of the entire China business in an effort to help bolster a potential merger between SpaceX and Tesla.
Musk immediately denied the rumor not once but twice, initially calling it “fake news,” and then calling it “absurdly fake news” in a separate post just a few moments later:
This is fake news
— Elon Musk (@elonmusk) July 31, 2026
The original poster of the Wall Street Journal article that Musk saw deleted the initial post sharing the headline and the rumored sale of Tesla’s China business.
This has never even come up in a discussion ever.
Absurdly fake news.
-People should assume news is fake until proven otherwise.
— Elon Musk (@elonmusk) July 31, 2026
The report seemed absolutely and unequivocally false to begin with; Tesla’s business in China is among the most important pieces of the company’s business. Not only does the factory supply vehicles for the domestic market, but also for various other markets in Asia and Europe.
China is also one of the largest automotive markets in the world, and Tesla has performed well there despite the robust competition.
The speculation regarding a Tesla and SpaceX merger has started to gain steam this year as the space exploration company went public just a month ago. There has been speculation that Musk will bridge all of his companies under one “umbrella company,” and analysts believe this could happen before the end of the decade.
The Tesla and SpaceX merger everyone is talking about is quietly building

This is the latest iteration of Musk’s very evident war on mainstream media. Reports regarding any of Musk’s companies are quick to get the dreaded “false” or “fake news” response from the CEO when they are unfounded.

Tesla AI boss reveals how big Optimus is going to get
Tesla’s Optimus chief corrected himself on X, confirming a staggering 10 million robot production target.

Tesla’s Optimus program has a new number attached to it, after Ashok Elluswamy, the executive who has run the humanoid robot program since June 2025, posted a three word correction on X Thursday, “Correction, 10 million robots.”
The line clarifies the long term annual capacity Tesla is building toward its planned second Optimus production line at Gigafactory Texas, a figure Musk has cited repeatedly since last year’s shareholder meeting.
The scale is worth noting, because ten million robots a year would mean Tesla building more units annually than most countries sell in new cars. Tesla has framed this as a second line, not the first. The buildout is happening in two phases: a roughly one million unit per year line inside Tesla’s Fremont factory, installed on the floor space vacated when Model S and Model X production ended earlier this year, and a much larger dedicated facility under construction at Giga Texas that broke ground on its first steel structure in May. That Texas facility is the one Elluswamy’s correction refers to, and is expected to reach volume production sometime in 2027.

Tesla Optimus project fires up as Musk sees production line progress
Elluswamy took over Optimus from Milan Kovac last summer and has spent the months since talking up the program’s trajectory. Elon Musk has also floated the ten million figure at Tesla’s 2025 shareholder meeting.
-
Ending Model S and Model X production to make room for the first Optimus line was one of the more consequential manufacturing decisions in the company’s recent history, retiring two flagship vehicles in favor of a robot that has yet to enter mass production. Musk has previously estimated per unit production costs at $20,000 to $25,000 once Tesla reaches a million units a year, though he hasn’t said what that cost looks like at ten times the volume.
