Elon Musk Says Sun Is 'Free' Fusion Reactor, Slams Companies 'Wasting Money' On Nuclear Energy: 'It Is Super Dumb…' - Tesla (NASDAQ:TSLA)
Benzinga· 2025-12-15 08:43
Billionaire Elon Musk has reaffirmed his commitment to solar power and criticized nuclear energy amid solar-powered orbital datacenter talks.The Sun Is A Free Fusion Reactor, Says Elon MuskTaking to the social media platform X on Sunday, Musk shared that the Sun was an "enormous, free fusion reactor" whose energy can be harnessed to meet the planet's power consumption needs. "It is super dumb to make tiny fusion reactors on Earth," Musk said.He also said that the Sun would make up to 100% of the Solar Syste ...

RT Eva Fo𝕏 🦊 Claudius Nero's Legion (@EvaFox)Elon Musk on the potential of energy harnessing:“As we progress along the Kardashev Scale, energy harnessed on Earth will increase a hundredfold and will mostly be solar aka fusion aka starlight.Then energy harnessed will increase perhaps a billionfold if we make it to Kardashev II, with space solar power, and another billionfold if we harness the energy of our galaxy.What I’m saying is that there is a lot of upside potential!!!” ...
Musk: The cost of AI in space will be better than AI on the ground. 🛰️

In space, you you've got continuous solar. You actually don't need batteries because it's always sunny in space. >> That's right.Exactly. >> Um and the solar panels actually become cheaper because you don't need glass or framing and the cooling is just radiative. So that's that's why I think >> that's the dream.>> My estimate is that actually that that that the cost effectiveness of AI in space will be overwhelmingly better than AI on the ground long before you uh exhaust potential energy sources on on Eart ...
Microsoft buys another 100 MW of solar, this time in Japan
TechCrunch· 2025-10-06 19:19
Core Insights - Microsoft is acquiring 100 megawatts of solar capacity from Shizen Energy to support its increasing compute needs through renewable energy [1] - The agreement includes four solar developments, with one operational and three under construction, covering output for 20 years [1][2] - Microsoft plans to invest $2.9 billion in Japan over the next year to expand its compute capacity [2] Industry Trends - Solar energy has become a preferred power source for tech companies and data center operators due to its quick and cost-effective construction [3] - Solar projects are among the cheapest new generating capacities, typically completed within 18 months, allowing users to access power before full project completion [3] - Microsoft has contracted over 1 gigawatt of solar capacity since the beginning of the year, indicating a strong commitment to renewable energy [3]
Meet the start-up testing space-based solar farms that use lasers to send power to Earth
CNBC Television· 2025-10-01 12:30
This is the launch vehicle for new space-based satellite technology designed to send solar power back to Earth. California-based startup Aetherflux plans to send it into space on a SpaceX rocket next year. Robin Hood co-founder Beiju Bot is the company's CEO.We're going to do a constellation of satellites where each one transmits power with infrared lasers. And the benefits of this are number one, you get to distribute the power generation across a lot of satellites as opposed to one monolithic one, but als ...

Water Scarcity and Challenges - Access to safe drinking water remains a significant global challenge, particularly in low-income countries [2] - Women and children in sub-Saharan Africa spend an estimated 40 billion hours annually collecting water [3] - High salinity levels make seawater unsafe for consumption, creating a paradox of abundance and scarcity [3][4] Desalination Technologies and Advancements - Early civilizations used basic distillation methods to purify water [5] - Modern desalination plants emerged in the 1950s in oil-rich, water-poor nations like Kuwait [6] - Singapore popularized reverse osmosis in 2010, turning sewage into ultra-pure drinking water [7] - Desalination provides approximately 42% of the UAE's water supply [7] Sustainability and Renewable Energy Integration - Desalination is energy-intensive and contributes to carbon emissions [8] - Solar-powered desalination offers a sustainable alternative, with the UAE uniquely positioned to lead this transition [9] - Abu Dhabi's Alawila is the world's largest desalination plant powered entirely by solar energy, producing 99,000 cubic meters of water per day [10] - The UAE consumes 500 liters of water per resident daily [10] Bottled Water Consumption and Environmental Impact - In the UAE, 25 billion liters (2.5% billion) of water are bottled annually [13] - Over 80% of people in the UAE prefer bottled water despite access to safe desalinated tap water [13] - The production, packaging, and transportation of bottled water contribute to significant environmental waste and pollution [14][15] Recommendations and Future Outlook - The industry needs a sustainable system for treating, transporting, and consuming water [16] - Decarbonizing desalination and scaling solar-powered desalination are crucial steps [16] - Eliminating plastic use in water packaging is essential for sustainable progress [16]
Vinod Khosla: Net zero is the worst idea I’ve ever heard for homes
Bloomberg Television· 2025-07-15 19:10
Energy Production & Consumption - Intermittent power sources like solar and wind are suitable for hydrogen production due to cost-effectiveness [1] - Using intermittent power to power a home is impractical because energy demand doesn't always align with energy production [1] Environmental Policy Critique - Net zero for homes is considered an uneconomical and poor idea [2] - Environmentalists are perceived to be promoting net zero for homes without considering economic factors [2]
