      Every source of energy can be “clean ” or “dirty” depending how much ethics or corruption is invested in order to gain that energy regardless its origin ( nuke, oil, gas, coal, hydro, wind, solar, kinetic, magnetic….).
      But what makes the “cleanliness” of the energy is also it’s usage. What’s the point having “green” energy if it going to be used to manufacture junk?

      What does big oil have to do with how electricity is conducted? Wind farms already exist. That electricity has to be conducted to the power grid in order for it to be used. Also, wouldn’t big oil want the electricity they produce to be carried more efficiently?

    There is an actual science behind why some people manifest wealth effortlessly while others struggle for years. It’s not luck, it’s about how your subconscious interprets vibrational frequency. I never understood this until I read Vibrations of Manifestation by Alex Lane. It breaks down the psychology behind manifestation in a way that finally made sense to me

  6. @RajGhosh-nj2rm

    February 18, 2025 at 8:28 am

    I’ve been experimenting with manifestation techniques, and something strange keeps happening. When I focus more on the vibrational frequency instead of just positive thinking, things actually start manifesting. I just finished reading Vibrations of Manifestation by Alex Lane, and it explains exactly why this happens. Has anyone else noticed this in their own life?

  7. @shardatelang1369

    February 18, 2025 at 8:28 am

    I used to struggle with manifestation because I always focused on positive thinking but never saw results. This book changed my perspective completely. Once I started applying what it teaches about vibrational frequency, everything shifted. It explains why most people fail at manifestation without even realizing it. I highly recommend reading Vibrations of Manifestation by Alex Lane

They help reduce our carbon footprint and reliance on fossil fuels. Investing in clean energy technology and supporting policies that promote renewable energy can make a big difference.

    • @BonnieShadow33

      February 18, 2025 at 2:24 pm

      Huh? No they wouldn’t. Just because power lines are able to transfer x amount of electricity, that doesn’t mean the wires in your home have to transfer that amount. If your computer is designed to use a certain amount of electricity, the wires are built to safely transfer that amount, and that’s the amount they pull from the grid. Unless you’re drastically increasing the electricity you *use*, the wires in your home should be perfectly fine.

    Building the facilities and equipment, transportation, etc all produce greenhouse gases and use large amounts petroleum and natural gas & will for a long time to come.

    The more accurate nomenclature is “alternative energy.”

    I mean people are saying this is an advertisement but that sort of detracts from the purpose here. He went on stage to inform the public on why this wire is important, calling to us to push regulation on better power infrastructure. His stake in his company doesn’t make his point moot, which is what I assume people are implying. In fact his call to action (10:07) doesn’t necessarily benefit his company since anyone can develop advanced conductors.

    3. I’m skeptical about the costs–seems like a product that sells itself in his telling, but here he is at TED selling… I am skeptical that the unbelievably long wires are not an appreciable piece of the cost and his fancier wires cost meaningfully more when strung up for 100’s (or 1000’s) of miles factoring in multiple lines on a given project

This week’s guest is Ayal Yogev, co-founder and CEO of Anjuna Security, who has experienced both sides of the startup journey: scaling quickly during the boom years and then making the incredibly difficult decision to lay off a significant portion of his team when the market shifted.

From growing to 75 employees to scaling back and rebuilding, Yogev learned firsthand that the hardest part of leadership isn’t hiring fast, it’s making tough decisions with care, transparency, and integrity.

In this episode, Isabelle Johannessen and Yogev unpack what it really means to lead through layoffs with compassion and how founders can support their teams even in the most challenging moments. They also explore the lessons learned from scaling too quickly and how to build a more resilient company the second time around.

Apply to Startup Battlefield: We are looking for early-stage companies that have an MVP. So nominate a founder (or yourself): techcrunch.com/apply. Be sure to say you heard about Startup Battlefield from the Build Mode podcast.
TechCrunch Disrupt: If you’re thinking about applying to Startup Battlefield, then October 13 to 15 in San Francisco, we’re back for TechCrunch Disrupt, where the Startup Battlefield 200 takes the stage. So if you want to cheer them on, or just network with 1000s of founders, VCs, and tech enthusiasts, then grab your tickets.
