Google’s giant “kite” can generate wind energy from almost anywhere

Published

on

A Google X division company named Makani has designed a giant “kite” that can generate enough wind energy to power about 300 homes. Named the “M600” after the 600 kW of electricity produced by its movement, the craft resembles a sport glider with two levels of multiple propellers on the front, more generally described as an aerodynamic wing. After more than ten years of development and a prototype test flight in 2016, M600 has begun full size testing in Hawaii this year to continue its journey towards becoming a portable power solution that can be brought anywhere with sufficient wind to propel it.

The functionality of M600 is fairly straightforward. After being connected to a 1400 foot high-strength tether, it uses 8 onboard motors to climb from a 15-foot base station to its determined altitude (about 1000 ft) with a small amount of voltage power. Then, it transitions into crosswind where it flies in 800 foot wide loops lasting 10-25 seconds each to generate maximum power via onboard computers guided by data from sensors, GPS, and an inertial navigation system.

The rotation of the 85 foot wide kite’s rotors drives magnet motors/generators on board, producing electricity that transfers down the tether where it can be connected to an energy grid. The electricity comes down in DC (direct current), but is converted to AC (alternating current) at its base station.

One of the needs driving Makani’s kite is accessing wind sources that aren’t practical or cost-effective in today’s markets. Its mass is about 10% of a conventional wind turbine with similar output thanks to the carbon fiber materials it’s primarily made from. The lighter, portable design of the M600 could help bring wind energy to areas devastated by natural disasters and places where coastal waters are too deep for other wind systems to sit on the seabed.

Google’s X division (under the broader parent company Alphabet Inc.) is a secretive development factory dedicated to radical innovations that solve the world’s toughest problems. It provided the initial funding for Makani’s kite technology as part of its 2007 RE<C initiative and officially graduated the company into X in 2013. As part of X, the company is working towards the one of the division’s missions of promoting global adoption of renewable energy and developing airborne wind energy technology.

Makani is not the only company developing flying wind generators. The “airborne wind energy” (AWE) industry is full of competitors developing their own versions. As a new clean energy technology, though, AWE companies face an uphill battle in becoming commercially viable due to research and development costs that take years, a problem faced by many new industries overall. However, as the technology comes to market and matures, AWE could follow the path forged by traditional turbine wind power which is now competitive with fossil fuels. A recent report by IDTechEx projected AWE will become a multi-billion dollar industry within 20 years.

The Makani team is continuing to develop more advanced versions of its wind energy kite while discussing the technical and economic integration aspects of the technology with industry experts. Initial ground and hover tests of the kite begun in Hawaii in August this year. In the coming weeks, the full 85-foot commercial version of the M600 will finally be tested.

Tesla has surpassed its job commitments at Giga New York in Buffalo, easing pressure from lawmakers who threatened the company with fines, subsidy clawbacks, and dealership license revocations last year. 

The company reported more than 3,460 statewide jobs at the end of 2025, meeting the benchmark tied to its dollar-a-year lease at the state-built facility.

As per an employment report reviewed by local media, Tesla employed 2,399 full-time workers at Gigafactory New York and 1,060 additional employees across the state at the end of 2025. Part-time roles pushed the total headcount of Tesla’s New York staff above the 3,460-job target.

The gains stemmed in part from a new Long Island service center, a Buffalo warehouse, and additional showrooms in White Plains and Staten Island. Tesla also said it has invested $350 million in supercomputing infrastructure at the site and has begun manufacturing solar panels.

Empire State Development CEO Hope Knight said the agency was “very happy” with Giga New York’s progress, as noted in a WXXI report. The current lease runs through 2029, and negotiations over updated terms have included potential adjustments to job requirements and future rent payments.

Some lawmakers remain skeptical, however. Assemblymember Pat Burke questioned whether the reported job figures have been fully verified. State Sen. Patricia Fahy has also continued to sponsor legislation that would revoke Tesla’s company-owned dealership licenses in New York. John Kaehny of Reinvent Albany has argued that the project has not delivered the manufacturing impact originally promised as well.

Knight, for her part, maintained that Empire State Development has been making the best of a difficult situation. 

“(Empire State Development) has tried to make the best of a very difficult situation. There hasn’t been another use that has come forward that would replace this one, and so to the extent that we’re in this place, the fact that 2,000 families at (Giga New York) are being supported through the activity of this employer. It’s the best that we can have happen,” the CEO noted.

Tesla has launched a vehicle-to-grid (V2G) program in Texas, allowing eligible Cybertruck owners to send energy back to the grid during high-demand events and receive compensation on their utility bills. 

The initiative, dubbed Powershare Grid Support, was announced by the official Tesla Energy account on social media platform X.

Texas’ Cybertruck V2G program

In its post on X, Tesla Energy confirmed that vehicle-to-grid functionality is “coming soon,” starting with select Texas markets. Under the new Powershare Grid Support program, owners of the Cybertruck equipped with Powershare home backup hardware can opt in through the Tesla app and participate in short-notice grid stress events.

During these events, the Cybertruck automatically discharges excess energy back to the grid, supporting local utilities such as CenterPoint Energy and Oncor. In return, participants receive compensation in the form of bill credits. Tesla noted that the program is currently invitation-only as part of an early adopter rollout.

The launch builds on the Cybertruck’s existing Powershare capability, which allows the vehicle to provide up to 11.5 kW of power for home backup. Tesla added that the program is expected to expand to California next, with eligibility tied to utilities such as PG&E, SCE, and SDG&E.

Powershare Grid Support

To participate in Texas, Cybertruck owners must live in areas served by CenterPoint Energy or Oncor, have Powershare equipment installed, enroll in the Tesla Electric Drive plan, and opt in through the Tesla app. Once enrolled, vehicles would be able to contribute power during high-demand events, helping stabilize the grid.

Tesla noted that events may occur with little notice, so participants are encouraged to keep their Cybertrucks plugged in when at home and to manage their discharge limits based on personal needs. Compensation varies depending on the electricity plan, similar to how Powerwall owners in some regions have earned substantial credits by participating in Virtual Power Plant (VPP) programs.

Tesla updates Cybertruck owners about key Powershare feature

Published

Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.

Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.

Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.

However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.

Powerwall discharge would be prioritized before tapping into the truck’s larger pack.

However, Tesla is still working on getting the feature out to owners, an email said:

“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026. 

This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”

Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.

Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.

Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:

He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”

It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
