I'm an orthopaedic surgeon, and I doubt it's anything more than just a typical spacer that is commonly used.

OK found the article, and I'm corect.

The title is misleading - it's just a 3D printed version of spacers that are commonly used - it really doesn't look, nor function any differently than the ones currently being used. The patient had a non-ossifying fibroma - rare in the spine, but benign, and will turn into regular bone eventually. This could have been treated with some bone graft and a plate and screws, which is basically what they did.

Nothing really new here.

While having a remote storage location is iseal for minimizing fallout risks, having an area that is sparsely seen y people can have security risks. It may be prone to terrorist type invasions, looking for dirty bomb material. I'm still not sure why a Nevada military type storage facility at Yucca mountain was blocked. - Guess NIMBY applies, even if your nearest neighbor is 200 miles away.

I think Porsche might want to argue against your quote about "being handled in a gentle manner" with the Al engine block on their GT3. It's been their most successful racing car engine for years and is bulletproof as far as those things go. In no way will the truck engine exceed the strains of a racing engine designed to run at high compression at 5-8.4K for hours on end. As far as strain - the truck has an automatic transmission which is easier on the engine, and puts out less HP and torque perdisplacement, lower compression, etc.

Of course there will be a few problems as there always are with something new, but to blame in on AL will be foolish. Hell, they even have had Al DIESEL engine blocks for a while.

Probably the vast majority of ANYTHING coming out - movies, music, books, etc is not very good. The stuff that survives is tried and tested good. A lot a good things are popular (Beatles, Sinatra, Nirvana, Stravinski, etc), but not all popular stuff is good (Brittany Spears, etc). The same goes for anything old, and the notion that they don't build them like they used too- well the hardy ones survived, and the crap broke.

Easy solution would be to have multiple smaller ones - I don't know enough electronics to know the advantages/disadvantages of having them in this situation in parrallel or in series, In this way, you might be able to "pop" charge your battery in very small increments. That is - have multiple small supercaps, that you quick charge, and have them hooked up to your battery (or even be the batery).
