    Seems like a lot is being promised here for a 7 month old startup with one employee- SW, multiple different HW components, high end thermal mechanics delivering all of this by EOY …

    Holmes never delivered a product that worked. Musk has delivered 4 Tesla models and counting, as well as VTOL rockets among many other accomplishments. Sure, he over-promises and u…

    Even if true, this will largely not affect a business like this. They make small money on each company and scale through the shear number of total companies that pay a few thousand…

    It would be very poetic if it turns out that one of these students actually had their test scores flipped by their parents without their knowledge.

    Real commercial espresso machines are still a very manual process for many reasons. This is something you’d see in the micro kitchen of an office or an airport lounge, not a Starbu…

    how long until we start seeing computer vision applications that translate sign language? It's a pretty hard problem, but definitely something that's feasible with the right method…

    Companies would also be incentivized to not have too many extra cars on the road at all as they would be paying for it in terms of their running costs.

    Sounds like you are starting to become an emotional investor in them, which is the worst type of investor.

    Sure, but a very bad nuclear incident (accidental or not) could more or less kill millions of people pretty quickly. Obviously hydrocarbons will kill more than that, but the optics…

    Nuclear has such a terrible reputation, and rightfully,people will always have legitimate complaints about it. We can never fully guarantee that a plant is free from the potential …

    Seattle has been doing this recently. I'm not sure if they have released any studies yet, but my observation has been a noticeable improvement.

    From the description, it sounds like a giant Peltier device, not a steam turbine (otherwise why would they care about having a cold tank?). Solar farms also have a ton of space in …

    Think of it like this: You produce energy at an amortized cost of $X /MW. You store energy efficiently (lithium batteries) at an amortized cost of $Y /MW back into the grid. You st…
