Dandelion’s geothermal system looks to heat and cool homes with renewable energy
Dandelion Energy, an energy startup conceived at Google’s Alphabet X innovation lab, is looking to bring affordable geothermal heating and cooling solutions to homeowners in the United States. Over the years, the clean energy company has grown its operations across New York State and is looking to expand its operations further, pursuing more research, opening new warehouses, and growing its team. The company has completed a $16 million Series A round that was led by Comcast Ventures and Google Ventures, bringing the company’s total funding to $23 million.
Similar to other clean energy companies such as Tesla, Dandelion Energy aims to liberate American homeowners from dependence on fossil fuels. Homes in the US typically utilize oil furnaces, which are costly and dangerous. A typical 2,500-square-foot Victorian home in Poughkeepsie, for example, could spend around $3,500 in winter for heating, and an additional $300 in the summer for air conditioning. Geothermal energy solutions, such as those offered by Dandelion, aim to cut these costs significantly.

At the core of Dandelion Energy’s vision is the Air, a heating and cooling system capable of harvesting energy from the ground. Unlike conventional geothermal residential systems that involve invasive, messy digging projects, Dandelion’s geothermal digging solutions are clean and efficient, resulting in deep holes that are only a few inches wide. Similar to other geothermal heat pumps, the Dandelion Air works by utilizing the difference in temperatures underground from the outside air. Thus, if the ground is warmer, the system would move heat from the ground inside to heat the home. During summers, the system would pump warm air from the house outside and underground. In true Silicon Valley fashion, the Air manages these processes automatically through software.
Geothermal heating and cooling systems present a notable advantage for the environment. Last year alone, the US saw its carbon emissions rise by 3.4% — the second-largest margin in two decades and reversing a three-year decline. In a report, the Rhodium Group listed buildings in the country as a factor in the emissions increase, partly thanks to unusually cold weather at the beginning of the year. This led to more demand for heating than expected, resulting in the increased carbon dioxide footprint of homes, offices, and buildings, many of which were using fossil fuel-powered furnaces. Had the use of residential geothermal solutions been widespread across the United States, these figures would have been notably lower.
With Silicon Valley roots, like fellow Alphabet X projects that eventually became their own companies, Dandelion Energy’s geothermal heating & cooling system has the potential to disrupt utilities by offering alternatives to conventional gas, oil, propane or electric heating. Other projects from Alphabet’s X labs that ultimately came into their own include self-driving car company Waymo, health data company Verily, and wearable tech platform Google Watch, which is now part of Android.
Dandelion Air’s upfront price is $29,247, though the company notes that the system would cost $19,423 after incentives are applied. Customers who wish to pay for the system through a loan are estimated to pay a monthly cost of $135 for the system. With the Air in place, homeowners could see savings of up to 20% for their heating and cooling needs.

NASA taps SpaceX to launch the telescope that could unlock new worlds
NASA’s Roman Space Telescope heads to orbit this August aboard SpaceX’s Falcon Heavy with massive scientific ambitions.
SpaceX is set to play a central role in one of NASA’s most anticipated science missions in years. The company’s Falcon Heavy rocket, currently the most powerful operational launch vehicle in the world, will carry the Nancy Grace Roman Space Telescope into orbit on August 30 from Kennedy Space Center in Florida. Roman is now in final preparations inside the Payload Hazardous Servicing Facility, where on June 26 technicians used a crane to lift the observatory into a specialized stand for fueling and pre-launch testing.
Roman is named after Nancy Grace Roman, NASA’s first chief of astronomy, whose career helped shape how the agency approaches space science.
NASA chose SpaceX Falcon Heavy because of Roman’s needs to reach a specific orbit far from Earth, well beyond where a standard Falcon 9 can deliver it. The Falcon Heavy, which first flew in 2018, has since become NASA’s go-to option for missions that need serious muscle without the cost and complexity of older launch systems.

Roman will carry a field of view at least 100 times wider than the Hubble Space Telescope, meaning it can photograph enormous swaths of the universe in a single shot rather than the narrow slices Hubble captures. That difference in scale is significant. While Hubble reshaped our understanding of the cosmos over 30 years, Roman is built to work faster and wider, surveying hundreds of millions of galaxies at once.
One of Roman’s most compelling capabilities is its potential to discover and photograph planets orbiting stars outside our solar system, and with enough precision to directly image planets that would otherwise be lost. That means scientists could study the atmosphere and surface characteristics of distant worlds rather than simply confirming they exist. Combined with Roman’s sweeping field of view, the telescope could detect thousands of exoplanets, and some of those planets may be in habitable zones where liquid water could exist. No telescope currently in operation has this level of power and capability. That capability alone could change what we know about other worlds, and perhaps finally answer the question: are we the only intelligent lifeforms in existence?
What Roman actually finds once it reaches orbit is an open question, and that is exactly what makes this launch worth watching.
Tesla has confirmed a crucial detail of its Miami Robotaxi launch, stating that the fleet is operating on an Unsupervised basis, joining a few other cities where company employees do not watch over the vehicles from inside.
Tesla’s Head of AI, Ashok Elluswamy, confirmed the detail on X, answering a highly speculated question about the Robotaxi Service in Miami, which was launched on June 3:
Unsupervised

The first launch of Robotaxi in Florida, Miami presents a unique opportunity for Tesla as it is operating the Unsupervised Robotaxi ride-hailing service in a major tourist hotspot in the Sunshine State. It also signals the suite will expand to other cities soon; many have requested Orlando, a heavy tourist spot with Disney and other resorts nearby, get access to the program soon as well.
Miami is getting a conservative rollout as well, just as Tesla has done with other cities. The initial geofence covers a compact 10–14 square mile zone in western Miami-Dade County, primarily West Miami extending toward Doral and Sweetwater. It is bounded roughly by SR-826 (Palmetto Expressway) to the north and US-41 (Tamiami Trail) to the south, excluding downtown Miami, Miami Beach, the airport, and most of Coral Gables.
Tesla has also been pretty slim on other details. For example, Tesla has not disclosed the exact fleet size, but field reports and license plate tracking indicate just two unsupervised Model Y vehicles were active on launch day, increasing to three within 48 hours.
According to The Road to Autonomy, a nearby staging lot near Miami International Airport holds dozens of Cybercabs alongside additional Model Y units, suggesting capacity for rapid scaling as demand and data collection grow.
The confirmation of Robotaxi being Unsupervised carries immense weight. It establishes that Tesla’s Miami Robotaxi operations run without human safety drivers or remote supervision, relying entirely on the company’s Full Self-Driving technology. Miami becomes the second major U.S. city after Austin to offer unsupervised Robotaxi rides from day one.
The move reflects rapid progress in Tesla’s AI efforts. Neural networks trained on vast real-world data now handle complex urban environments, including South Florida’s heavy traffic, pedestrians, and rainy conditions. Industry observers see it as validation of Tesla’s vision-centric, data-driven approach versus traditional rule-based systems; a truly unorthodox approach in this day and age.
Challenges remain, including regulatory oversight, public trust, and scaling the fleet to match geofence ambitions. Miami’s small initial footprint and limited vehicles highlight a deliberate, measured expansion strategy focused on safety and data gathering.
Nevertheless, the unsupervised confirmation marks a pivotal milestone. It showcases technical readiness and advances Tesla’s vision of transforming vehicles into autonomous revenue generators while reshaping urban mobility. For Miami users, driverless transportation has moved from concept to reality.
A California radiologist who drove his Tesla Model Y off a 250-foot cliff in an attempt to kill his family has had his charges dismissed after doctors say he is “doing well” in a mental health program.
Dharmesh Patel was charged with three counts of attempted murder in connection with a January 2023 crash where he drove his Tesla off a cliff, injuring his wife and two children, aged 7 and 4 at the time.
Patel drove the Tesla off Devil’s Slide in California, an area that is extremely rough to the point that investigators and rescuers expected the worst when arriving at the scene for the first time. Patel supposedly had schizoaffective disorder, according to Deputy District Attorney Dominique Davis.
Shockingly, Patel’s wife, who was in the vehicle, testified that she did not want her husband to be prosecuted, noting that their children missed their father and they wanted him to come back home. Patel’s attorney argued, “not everyone who commits a crime is a criminal.”

A three-day trial in Mental Health Diversion Court ruled in Patel’s favor, which kept him out of jail and instead on house arrest. He was admitted to a Mental Health Diversion Program, which he successfully completed, the Associated Press reported. San Mateo County District Attorney Steve Wagstaffe said the judge was “required by law” to dismiss the charges:
“If the person who’s given mental health diversion follows the treatment plan, there’s nothing that can be done, and at the end of the two years he gets it wiped out of his record.”
Wagstaffe said he has argued, along with other DAs in California, to have attempted murder removed from the list of charges eligible to be dismissed due to mental health diversion programs.
Patel had the charges officially dismissed on Monday; his wife waited for him as he left court and they departed the building together, according to Mercury News. Patel surrendered his California medical license in December.
The crash has been one of the best examples of Tesla’s incredible engineering, which has saved four lives in this particular instance. The car was totalled but kept the four human beings alive and safe, which is something that many referred to as “an absolute miracle.”
