    A great interview! Dr. Holme is very smart and trustworthy in the field where many people and companies are making a lot of false claims and setting up unreasonable expectations of their work. Matt, it would be good if you can do more videos like this, interviewing other SSB developers and then one video comparing these SSB technologies. Many people are skeptical and under-educated in the field of SSB because there are too many non-sense media headlines. Perhaps you can help us be more educated.

      One of his false claims is, a lot of energy must be stored on the vehicle. Recent test track experiments have proven that it is possible to put the energy in the road and transfer it to the vehicle through induction. Only a very small battery would be required, to get you from your garage to the electrified highway.

    LOVED the interview!! When you’re enthusiastic about a potential new product, that you have put your personal capital at stake on, it’s important to remember that someone like Dr. Holme is ALWAYS a representative of a public company and is restricted from going too far with assertions and/or “facts” that have yet to be released to the public in a “proper” format. I tune in wanting to hear a specific company, a particular car, or an exact date of deployment. Only to realize that’s just not going to happen. But what does happen is that the “tone”, or excitement in the discussion processes a different tenor towards the future. Dr. Holme never acknowledged the timeline statements of 5-10 years to come. In fact he used terms intimating decidedly shorter timelines, like “acceleration” and “fairly quickly” to insinuate scale of timelines. I’m very excited after this interview for the next 12-18 months ahead for QS, PowerCo, and VW! Stay tuned!

Even if China sacrifices battery cycle life by charging so aggressively, if battery replacement cost is very low, that might be the answer.

    • @glenndennis6801
      @glenndennis6801 Месяц назад +1

      Not really, a generator can be run at a constant speed and only when needed, making it somewhat more efficient. Whereas a propulsion engine has to run all of the time and at different speeds. If you have a battery to power the drive wheels and with regenerative braking, a lot less energy is needed to move the vehicle, so even with the dual system, it is still more efficient. Check out Edison Motors and their electric logging truck. Also the Ram new pickup truck is supposed to be this way.

    VW announced a battery plant here in Ontario, Canada sometime in 2026-2028. I can see them betting on QS/PowerCorp coming through with commercialization so that this plant will build SSB.
    The viability in the early run could be used in hybrids since the US market isn't 100% ready to go BEV especially with expensive SSB. Early SSB can be used in higher priced vehicles from the VW family (Bently, Porsche and Audi).

    I have followed SSB development closely. This is the best video I have listened to about the the overview of SSB and QS status. Essentially QS has transferred mass production to VW. So far only Toyota and QS have announced commercialization of SSB schedule, 2027 - 2028. Both CATL and BYD are behind by 2 - 3 years. Tesla is not in SSB game. It depends on CATL improved Li ion batteries which still catches fire. Elon Musk is missing the boat.

    VW badly needs a win given their huge debt and loss of market share. Hopefully this collaboration with QuantumScape and commercialization comes fast enough. In some ways the 'race' metaphor still applies because other chemistries already in mass production are able to swap out components without (much) retooling, at which point the win on cost. No one is standing still.

    Whats concerning to me is how these execs at QuantumScape are selling tons of stock every month including Dr. Holmes here, even though the stock is trading at near record lows. Singh Jagdeep has been selling $1.5 million worth of stock every month. If they were so confident in the future of QS they wouldn't be selling so much, if they were so confident in the future they would actually be buying more stock at these record low levels. How many people need $1.5 million per month to live on?

      They are selling a low single digit percentage of their total available shares. That still projects confidence to me. They also get refreshed with new shares per compensation or performance every year.
      Think of the shares they’ve sold as a percentage of their own perceived chance of failure (more or
      Less). They’re holding over 90% of their shares. So at worst they are guessing a single digit chance of failure.
