Tech Stuff 8

This is a sort of search and discover newsletter of my findings of things that may relate to technology in one way or another.  It might be the latest gosh wow tech, it might be something as old of humanity.  It might relate to science large or small.  It might be art for art’s sake.  Or somebody just doing something funky. Because I think that technology is just the representation of human creativity and breaking boundaries.  So I’m certainly not going to place boundaries here except that it won’t be the same old, same old.  So almost no gadgets or yacking about the latest phone or whatever, unless of course it involves taking them apart or destroying them in unusual ways.  Or putting them to work in imaginative ways that most people won’t even think of.  So buckle up, it’s going to be a fun ride.

When you watch green energy stuff for long enough you see a lot fuzzy wuzzys and stuff that makes you go WTF if you know something about the technologies involved.  Normally this stuff comes from fly by night operators making stupid exaggerated claims to attract people with more money than sense.  I don’t usually see a fuzzy wuzzy from somebody reputable.  Well at least until now.  Sorry GE, but WTF is this:

First of all, this is a bottoming cycle, not some sort of energy storage method.  That’s because in Potasium salt plant, the LAST thing you want is to let the salt get too cold and solidify, so you are NEVER going to remove heat while the salt isn’t being heated.  Second, making dry ice is a very poor way of storing energy because of the thermodynamics of getting the CO2 to that state in the first place.

Then there’s that little turbine based on the shaft on the desk and some fairly generous calculations you have to have that little shaft turning over at 150,000 rpm to get 100 megawatts.  That means the best bearings ever, no imbalances in the shaft of any kind and no fluid instabilities of that turbine will self destruct in rather spectacular fashion.  I expect this sort of thing  from disreputable types with political connections trying to scam the ignorant. Is that what GE is now?

The end of the garage?

The garage has produced just about every major innovation in the last century.  I don’t think that that’s going to change.
