This L.A. startup uses SpaceX tech to cool data centers with less power and no water
As the artificial intelligence industry heats up, Karman Industries is trying to cool it down.
The Signal Hill startup says it has developed a cooling system that uses SpaceX rocket engine technology to rein in the environmental impact of data centers, chilling them with less space, less power and no water.
It recently raised $20 million and expects to start building its first compressors in Long Beach later this year.
“Our high-level thesis is we could build the best compressor out there using the latest and greatest technology,” said David Tearse, chief executive of Karman. “We want to reduce that electrical consumption of cooling so that you have the most efficient way to cool these chips.”
The high-end, expensive chips that power AI can slow down or shut off when they overheat. They can reach more than 200 degrees, but need to be below 150 degrees to work best.
Cooling warehouses packed with tens of thousands of them can require fields full of equipment and huge quantities of water.
Karman has developed a cooling system similar to the heat pumps in the average home, except its pumps use liquid carbon dioxide as refrigerant, which is circulated using rocket engine technology rather than fans. The company’s efficient pumps can reduce the space required for data center cooling equipment by 80%.
Over the years, data centers have used fans and air conditioning to blow cold air on the chips. Bigger facilities pass cold liquid through tubes near the chips to absorb the heat. This hot liquid is sent outside to a cooling yard, where sprawling networks of pipes use as much water as a city of 50,000 people to remove the heat.
A 50 megawatt data center also uses enough electricity to power a mid-sized city.
As AI has super-sized data centers, adding more and more chips, they have needed increasing amounts of space and power for cooling.
“It’s kind of a losing battle, especially when you keep densifying your chips,” said Tearse.
Cooling systems account for up to 40% of a data center’s power consumption and an average midsized data center consumes more than 35,000 gallons of water per day.
Nearly 100 gigawatts of new data center capacity will be added by 2030 and energy constraints have become the biggest barrier for expansion. U.S. data centers will consume about 8% of all electricity in the country by 2030, according to the International Energy Agency.
Communities across the U.S. have begun protesting data center construction, fearing that the power and water needs could strain infrastructure and boost costs to consumers. The cooling systems are projected to use up to 33 billion gallons of water by 2028 per year.
Big tech companies and venture capital investors are spending billions of dollars to replace old-school technologies with energy-efficient solutions. Microsoft announced a new data center design that uses zero water for cooling. It recently vowed to ensure its data centers don’t increase the electricity costs or deny water to nearby communities.
The data center-cooling market is projected to grow from about $11 billion in 2025 to nearly $25 billion by 2032.
To serve this seemingly insatiable market, Karman has developed a rotating compressor that spins at 30,000 revolutions per minute — nearly 10 times faster than traditional compressors — to move heat.
“Three or four years ago, it was very challenging to do just because the motors didn’t exist. Automotive components are getting up to those speeds,” said Chiranjeev Kalra, co-founder and chief technology officer of Karman.
About a third of Karman’s 23-person team came from SpaceX or Rocket Lab, and they co-opted technologies from aerospace engineering and electric vehicles to design the mechanics for the high-speed motors.
The system uses a special type of carbon dioxide under high pressure to transfer heat from the data center to the outside air. Depending on the conditions, it can do the same amount of cooling using less than half the energy.
Karman’s heat pump can either reject heat to air, or route it into extra cooling, or even power generation.
One of the potentially biggest selling points for the systems is that they don’t require water, which will enable data centers in spots where water is scarce.
In really hot places such as Texas and Arizona, cooling systems struggle, either using excessive water to cool or having to throttle the chips to stop them from overheating.
Karman’s latest funding round brings the total money raised to more than $30 million. Major participants included Riot Venture, Sunflower Capital, Space VC, Wonder Ventures, and former Intel and VMware CEO Pat Gelsinger.
Karman said it will begin customer deliveries in the summer of 2026 from its Los Angeles manufacturing facility that is designed to make 100 units per year. The plan is to eventually quadruple capacity.
If successful, Karman could dent the market share of Trane Technologies and Schneider Electric, the leaders in heat rejection systems.

Waymo reports teen riders for bad behavior and delivers them to the police
Robotaxis could be turning into robocops.
A self-driving Waymo reported two teens to San Mateo, Calif., police on Monday after they were found drinking alcohol and shooting toy guns in the back of the vehicle.
According to a social media post from the San Mateo Police Department, officers detained two 15-year-olds after the Waymo they were riding in contacted the department and stopped in a parking lot until law enforcement arrived.
“Parents do you know where your teens are?” the San Mateo Police Department wrote on Facebook following the incident. “Waymo does!”
Officers removed both teens from the vehicle and determined they were using toy guns to shoot Orbeez out the windows. Orbeez are small, water-absorbing beads sold at toy stores.
“Toy guns, water guns, and BB guns all pose real dangers, especially to an untrained eye,” the Police Department said. “The simple handling of them can cause fear in [passersby].” “
A video posted on Facebook shows at least five officers and a police dog responding to the scene and approaching the Waymo with their weapons raised.
Waymo did not immediately respond to a request for comment.
Waymo vehicles have internal cameras and microphones that may be used in an emergency or to “promote safety and security,” according to Waymo’s online support page.
The cameras are also used to ensure the vehicles are clean and to help find lost items, according to the support page.
The company said it does not use facial recognition or other biometric identification technologies to identify individuals.
“In more urgent circumstances, support may access live video during a trip,” the Waymo page said.
The San Mateo Police Department’s Facebook post has garnered nearly 60 comments, with one user accusing Waymo of “snitching.”
“At least they got a designated driver?!” one user commented.

Commentary: How right-wing anti-transgender attacks led to a Supreme Court ruling upholding sex discrimination
At the Supreme Court, the unfounded fear of boys masquerading as girls in youth sports rolled the clock back on gender equality.
On the surface, the Supreme Court’s June 30 opinion upholding state laws barring transgender girls from women’s and girl’s sports teams looks like a victory for women’s rights.
The 6-3 opinion by Justice Brett M. Kavanaugh certainly presents itself that way. “Females and males have inherent physical differences relevant to athletic performance,” Kavanaugh wrote. “Therefore, in contact sports, forcing female athletes to compete against males can create significant safety risks.” He also asserted that “forcing female athletes to compete against males can undermine competitive fairness.”
The ruling applied to prohibitions enacted in Idaho and West Virginia against “biological” males’ participation on women’s teams in public schools. Federal judges in both states overturned the bans. The Supreme Court majority restored them. The ruling essentially upholds similar bans enacted in 25 other states.
There was no record of any transgender person participating in school sports in the State, let alone any ‘problem’ with transgender students … creating unfair competition or unsafe conditions.
— Justice Sonia Sotomayor, demolishing the Supreme Court’s argument in favor of banning transgender girls from girl’s sports
Kavanaugh, like Donald Trump and others in the anti-transgender camp, maintained that one’s gender is an immutable fact of life, established even before birth.
Anything else, Trump stated in an executive order he issued on inauguration day 2025, could only be the product of “gender ideology extremism.” The U.S., his order stated, recognizes “two sexes, male and female. These sexes are not changeable and are grounded in fundamental and incontrovertible reality.” That’s a “biological truth,” he declared.
In his own version of this overconfident and factually insupportable conclusion, Kavanaugh wrote: “As all agree, females and males have inherent physical differences relevant to athletic performance.”
Science recognizes that some people are “born with sex traits that don’t fit into typical male or female patterns,” to cite a discussion on the Cleveland Clinic web page on the topic “intersex.” The condition “may involve chromosomes, hormones, reproductive organs or genitals.”
From a psychological standpoint, medical science recognizes “gender dysphoria” as a real condition often requiring counseling and medical intervention such as the use of puberty blockers and hormones to stave off the development of secondary sex characteristics until the condition can be resolved.
No one disputes that there are physical differences between the sexes. Few would dispute that on average or even at the median, males may be bigger and more powerful than females, or that in certain contact sports the difference may be telling and on occasion dangerous.
But that’s not the same as asserting that the physical differences between males and females invariably mean that men will invariably prevail over women in all competitions or that their participation will endanger women.
The International Olympic Committee — in a policy statement Kavanaugh cited incompletely — says that in “most running and swimming events,” males have a 10% to 12% advantage over women. That’s a range that would accommodate the full spectrum of outcomes — transgender females win, cisfemales win, they tie. (The “cis” prefix denotes those living consistent with their birth gender.)
West Virginia and Idaho addressed this ambiguity by banning transgender women from all girls’ teams. So under their rules transgender girls can’t play football or soccer with cisgirls. But what’s the argument in favor of banning them from the 100-yard dash, or cross-country track, or diving, or archery?
But something else is going on here. The Supreme Court’s ruling was almost preordained, given the years-long campaign by conservatives to demonize transgender individuals as if they’re members of an alien species.
It will be recalled that during his presidential campaign, Trump spun a despicable fantasy in which children were kidnapped in school and secretly subjected to sex-change operations.
Trump’s executive order wiped out policies aimed at protecting transgender adults from discrimination. He moved to outlaw gender-affirming medical therapies for anyone under 19 by cutting off federal funding for healthcare institutions that provide such care.
He banned transgender individuals from serving in the military and ordered federal prison officials to move transgender inmates into the general populations consistent with their birth genders, which exposes them to physical assault. (Federal Judge Royce Lamberth of Washington, D.C., has blocked the government from transferring three transgender women into the male prison population or terminating their hormone treatments.)
I wrote during Trump’s first term, when his anti-transgender policies were still gestating, that the goal was to show that “one can target any community, as long as it doesn’t have a strong political voice or political power. These are the actions of bullies and cowards, pretending to be strong.”
Last year, the Supreme Court struck its first blow against transgender rights by upholding a Tennessee law banning transgender care, including puberty blockers and hormone therapy, for minors. Similar laws have been enacted in 25 other states. The majority in that ruling by Chief Justice John G. Roberts Jr. was identical to the one in the June 30 ruling — Roberts, Kavanaugh, and Justices Clarence Thomas, Samuel A. Alito Jr., Neil M. Gorsuch and Amy Coney Barrett.
Who are the targets of this ideological campaign? They number only about 1.6 million U.S. adults, or one-half of 1% of the U.S. population. About 300,000 adolescents ages 13 to 17, or 1.4%, identify as transgender, according to a study by UCLA School of Law.
In West Virginia, as Justice Sonia Sotomayor observed in her dissenting opinion, “there was no record of any transgender person participating in school sports in the State, let along any ‘problem’ with transgender students … creating unfair competition or unsafe conditions.”
In endorsing the flat bans directed at transgender women in Idaho and West Virginia, Kavanaugh argued that any attempt to implement case-by-case judgments of students’ requests to join sports teams inconsistent with their biological gender would create “an enormous practical and administrability problem.”
Is that so? That wasn’t the case in Maine, where the annual K-12 population is more than 170,000. There, a committee was charged with determining whether a student’s participation in a sport consistent with their gender identity but inconsistent with their biological sex would “result in an unfair athletic advantage” or present a risk of injury to others. The committee held 56 hearings from 2013 through 2021, or an average of seven per year. During the entire time span, only four involved transgender girls. (The outcome of those hearings couldn’t be learned.)
It was Maine’s policy, one might recall, that provoked a confrontation between Trump and Maine Gov. Janet Mills at the White House last year, when Trump threatened to withhold federal funding from the state unless it barred transgender students from competing on women’s sports teams. “We’ll see you in court,” Mills snapped.
Whether the Idaho and West Virginia laws genuinely protect girls from unfair competition is questionable. (The Idaho law is styled the “Fairness in Women’s Sports Act.”) In practice, the laws may subject women in public schools to “invasive sex verification procedures,” as educational expert George Theoharis of Syracuse University wrote after the court ruling.
They’re also based on a retrograde view of women as fragile creatures needing men’s protection, Theoharis wrote — “the same logic that has historically been used to justify excluding women from making their own healthcare decisions and girls from rigorous math and science; that physically demanding work is simply beyond them.” (There don’t appear to be any state laws barring transgender women from competing in men’s sports.)
Becky Pepper-Jackson, the plaintiff in the West Virginia case, in which she is identified only as B.P.J., is the only transgender girl who sought to join girl’s teams — track and cross-country — in the state. That was in 2021, just after West Virginia passed its law and she was about to enter sixth grade. She didn’t appear to pose any competitive risk to others on the track and cross-country teams she applied to join — her lawyers told the Supreme Court that on those no-cut teams, she “came in near the back.”
Anyway, she had not gone through male puberty, which theoretically might have endowed her with a competitive advantage, because she had been taking puberty blockers and female hormones.
Thanks to the court’s ruling, Sotomayor observed in a dissent joined by Justices Elena Kagan and Ketanji Brown Jackson, West Virginia can deny Becky access to school sports “because it thinks they have an inherent athletic advantage, even if the facts show that they do not.”
B.P.J., Sotomayor wrote, “cannot practice on girls’ teams, even if she would not take anyone’s spot in an eventual competition, even if everyone who tries out for the team makes it, and even if having the chance to participate could aid immensely in treating B. P. J.’s gender dysphoria.”
So whose interest was really protected by the Supreme Court?

Orange County real estate investor pleads not guilty in $100 million bank fraud case
An Orange County real estate investor accused of criminally defrauding an Arizona bank of nearly $100 million pleaded not guilty Monday and remains in custody.
Mahender Makhijani, 44, of Corona del Mar — who also was ordered by an arbitrator to pay $1.34 billion in a separate civil fraud case — was arraigned in Santa Ana federal court on two charges.
He is accused of bank fraud and making a false statement to a bank in a June 8 case involving a $100 million real estate loan made by Phoenix-based Western Alliance Bank. He was taken into custody on June 10.
Makhijani is accused of providing bogus collateral for the October 2024 loan now in default. In a civil lawsuit, Western Alliance said the outstanding balance as nearly $99 million.
Prosecutors say he falsified title insurance policies that showed the bank would have a first lien on the underlying collateral if the loan went bad, when in fact it did not.
A trial was set for August 11 before U.S. District Judge David O. Carter in Santa Ana.
Michael Schachter, his criminal defense attorney, did not respond to messages seeking comment.
In the civil case, an arbitrator in May ordered Makhijani to pay Laguna Beach real estate mogul Mohammad Honarkar $1.34 billion after ruling he had fraudulently induced him into a 2021 joint venture — and then wrested control and lost to creditors more than two dozen properties Honarkar had owned.
Makhijani has not been criminally charged in that case, but prosecutors alleged in an affidavit in support of the bank fraud charges that he used “force and threats” in his dealings with Honarkar and others — including taking over the landmark Hotel Laguna in 2023 that Honarkar was renovating.
Prosecutors sought to hold Makhijani without bail after his arrest.
The affidavit noted he is a legal Indian immigrant with a home and bank accounts in that country, has access to private jets and threatened to “run away” if caught in a difficult situation.
The request was denied and he was granted $500,000 bail.
However, Makhijani remains in custody after a hearing sought by prosecutors last month before Magistrate Judge Autumn Spaeth.
The judge declined to accept a $450,000 cashier’s check submitted by a Makhijani associate for the bail, finding insufficient proof the source of the funds was legitimate, according to court records.
Makhijani is not prominent outside Orange County real estate circles, but he established a thriving distressed-assets business over the last decade that attracted prominent Southern California real estate investors.
Prosecutors said it paid for a lifestyle that included two multimillion-dollar homes in Corona del Mar, a luxury apartment in Newport Beach and various luxury vehicles.
As of last month, prosecutors had not fully traced his assets, which they believe are not held in his name and some of which may be in India.
The businessman employed an array of shell companies and strawmen to sign documents on his behalf, and to stand in for him as operators of his companies, according to the affidavit.
Makhijani told an associate he took extra precautions because wanted to insulate himself from litigation and that “they were sharks in the distressed world who took advantage of people,” the affidavit stated.
