  • Exactly. The Semantic Web is broader than Solid but Solid is great for personal apps.

    Say you buy a smartphone. The specifications of the smartphone likely belong elsewhere than in a Solid Personal Online Datastore, but they can be pulled in from semantic data on the product website. Your own proof of purchase is a great candidate for a Solid POD, as is the trace of any repairs made to it.

    These technologies are great to cross the barriers between applications. If we’d embrace this, it would be trivial to find the screen protector matching your exact smartphone because we’d have an identifier to discover its type and specifications. Heck, any product search would be easier if you could combine sources and compare with what you already have.

    The sharing tech exists. Building apps works also. Interpreting the information without building a dedicated interface seems lacking for laymen.


  • IPFS would replace Content Delivery Networks in present day.

    It would also allow you to host software and other content from your own network again without the constraints modern Internet Service Providers pose on you to limit your self-hosting capabilities.

    If applications are built for it, it could serve as live storage for your applications too.

    We ran ipf-search. In one of the experiments we could show that a distributed search index on ipfs-search, accessible through JavaScript is likely feasible with the necessary research. Parts of the index would automatically be hosted by clients who used the index thus creating a fairly resilient system.

    Too bad IPFS couldn’t get over the technical hurdles of limiting connection setup time. We could get a fast (ElasticSearch based) index running and hosted over common web technologies, but fetching content from IPFS directly was generally rather slow.












  • With that explanation I am still not clear whether the statistic on percentage of recycled batteries was car batteries, the battery industry as a whole, li-ion batteries, rechargeable batteries, … I am honestly interested in which statistics you are referring to. Especially the evolution of recycling of car batteries and the regions where recycling and collection occurs.

    It seems you are adding uncertainty and doubt on the topic of battery recycling which I’m not sure is grounded. We are well past the point in our environment where we can live our current lifestyle in the way we live it today. We have to adapt to a different lifestyle and make strategic bets. It seems clear that we should stop pumping up oil and electric cars may help there. I’m looking for research that indicates that current car batteries are waiting in stockpiles to be recycled but no plants exist to recycle them.

    As far as I can tell, there are not even enough bad battery packs around to suit the diy hackers to reuse them for home energy storage and with some luck your research points me to where I can find them.


  • Are you talking about Li-ion batteries in general, or car batteries?

    I don’t think there are many car batteries to be recycled yet. Only the Leaf’s batteries degraded sufficiently to warrant replacement and even those seem to be used with shorter range. Tesla batteries with faults get refurbished IIUC. The ev conversion market likes to use second hand packs and prices are strong because there are too few.

    I have read that recycling is feasible and realistic but did not bother to check. Can you point to the research that says it is hard and that the batreries will serve no future use as is?
