  • For c to c cables, the devices need to be able to communicate with each other to establish which one is the host (the charger in this case). With a to c cables, the type a side is assumed to be the host by default. You’ll often find that manufacturers of cheaper devices prefer not to spend the extra money to implement this technology, though some will, and in fact allow for even more functionality. For example, one of my flashlights does have that chip, so it can both charge from a c to c cable if a charger is detected, and also automatically act as a power bank if I connect a device to it such as a mobile phone.










  • The space shuttle was never meant to be ‘reusable’ but rather ‘refurbishable.’ The big difference is that Starship is designed from the ground up for rapid reusability, without manually checking each of the 24000 unique tiles of the STS orbiter.

    With the stainless steel construction, SpaceX is aiming to use their new upper stage up to 3 times a day with only refueling and a basic check in between. It is a complete paradigm shift from traditional rockets.



  • You’re comparing the world’s first fully reusable rocket that also happens to be the world’s most powerful operational rocket to old technology? The payload capacity of this vehicle is immense. There is not a single aspect of it that isn’t brand new, from its proportions, engine power cycle, engine amount, construction materials, you can go on almost endlessly.

    These incremental tests are what allow them to move at this incredible speed. Traditional rocket development doesn’t take years, it takes decades. You have to consider that this isn’t a government trying to outcompete another one, it’s a private company. They are pushing the envelope with everything they’re doing.
