    It'd be nice if they had some pictures of placed nanotubes rather than the generic nanotube spaghetti they show. Maybe make a logo like 'C12' with them to show the pick and place p…

    This is an experimental demonstration of the technology that makes Neal Stephenson's "Diamond Age" possible. They place an individual carbon atom pair(dimer) on silicon. Silicon ha…

    There are proposals for the 6G standard to support Integrated Sensing and Communication(ISAC)[0]. So the hardware might natively be able to support gait recognition. The use cases …

    Industrial robots at least are very reliable, MTBF is often upwards of 100,000 hours[0]. Industrial robots are optimized to be as reliable as possible because the longer they last …

    This will probably need to be updated soon. There are rumors NIF recently achieved a gain of ~4.4 and ~10% fuel burn up. Being able to ignite more fuel is notable in and of itself.…

    And why wouldn't it work? Linear slide like mechanisms consisting of a silver surface and single molecule have been demonstrated[0]. The molecule only moved along rows of the silve…

    A similar single motor robot hand has been made that uses electrostatic clutches instead of mechanical clutches[O]. [0] https://arxiv.org/abs/2501.08469

    At some point, making mechanical watches more complicated will require going digital. It is possible to make very small gears with semiconductor processes, however, very small gear…

    I would not consider this a 'robot' because power and control is not on board. It's more of a puppet than a robot. At the very least, the magnets should be included in the size of …

    What's interesting is the vision language capability they have. Being able to verbally describe tasks and determine if a task was completed means they might be able to do self-play…

    Perovskite solar cells could be and dye sensitized solar cells can be[0]. The better question is why should one make solar cells at home? [0] https://www.instructables.com/How-to-B…

    Anything you want and can launch into space. The program goal is being able to grow large structures. The intent seems to be using biology as a means to more efficiently transform …

    It's useful for grid storage. Very large amounts of hydrogen are already stored in salt domes[0]. Current salt domes have volumes in the range of hundreds of cubic kilometers and c…

    You could use it to model a CNC machine, but you'd probably need to make new components. It would also be difficult to model the changing load as the spinning tool plunges into met…

    It's 4x more efficient at solar to food production than regular plants with the potential to get a 10x improvement.

    There was a whole field called fluidics that focused on performing operations analogous to those performed with electricity. This[0] gives a good overview of how fluidics worked. O…
