  • Well, not necessarily. How about just embedding the following in the EXIF tag: digital signatures from the original camera; digital hashes of the original image; digital sigs for the publisher and the article where the pics will appear.

    Any additional processing by a “social media content creator” - for example, adding captions to make a meme out of it - will also include the prior chain of digital sigs and hashes.

    Now when it pops up on social media sites/apps, there can be little info bubbles that link to the original pic or article, or provide info on ownership of the camera along with date and timestamps of the pics.

    Garbage will always exist on social media, but at least we can have these little tools to verify authentic images.


  • Hydrogen is a dead end, because it is nowhere near green to produce it in large quantities, and the technology is still not ready, nor is the supply network. It’s just an idea pushed by fossil fuel companies hoping to transition to selling hydrogen.

    E-fuels are not zero emission, but the basic premise is that somewhere else along the chain it reduced GhG emissions into the atmosphere - like capturing methane from cow burps, or biogas from garbage dumps.

    These fuels will have uses - hydrogen in rockets and e-fuels for aircraft - but for almost all land vehicles, BEVs or going electric, is the most readily available and working strategy.
