[Tech News] Interesting technology

or this one, pretty impressive home built printer. I'm guessing it 
has 600-1000- dpi resolution.

speaking of Popular Mechanics above, they had a pretty negative article 
when this process was announced
wow, that's nice output!

North America is convinced that anything related to "fusion" is fake 
or star-trek futuresque.  


the "Pons-Fleischman debacle", was such big news that they completely 
discredited this research in the public, so anything related to this 
field has been regarded as skeptic material ever since.   talking 
about functional cold fusion is almost on par with talking about 
UFOs.
current common sense in N-A would be:  "if its not fire or hot wires... 
its obviously dangerous or else its fake"
wrt printer, yeah, I REALLY hope he gets the plans out, I'll build 
one for sure.  my dad has a commercial machine shop with milling 
machine and all the rest.
I'd have sooo much fun with this stuff.  building toys and physics 
experiments with my kids.

it kills me to see the poisonous comments lots of skeptics make about 
the Rossi process without even having looked at the details. They're 
forgetting that with the knee-jerk disbelief they're essentially 
saying that the last 20 years of positive yet inconsistent results 
have been meaningless (quoting myself from some blog or other)
can't wait for the plans for the printer - did I already say wow? 
Wow

me too... the "shiny" parts really show how much resolution he has.
we could build our own legos  :-)

A house plus store just completely exploded here today in the Netherlands 
due to gas, so I guess Maxim is right that switching bombs would 
be acceptable

btw, the one thing I have not seen answered wrt the Rossi invention 
is if explosions are radio-actively "dirty".   

if its easy to make these systems, and then eplode on demand, (by 
a simple switch it on) it becomes a rather disturbing technology 
if the explosion itself leaves radio-active elements behind.

the radio-active isotopes produced are very short lived so basically 
when the reaction stops there is nothing radio-active left

And it's very little matter, that's involved in the fusion (if it 
work). I don't think, it'll be a big problem, unless the process 
can run uncontrolled somehow, like a fission meltdown. It's hard 
to judge, because the claimed process isn't very well understood 
(yet).

Yes, I gave "effective" price with tax.  Since I don't really care 
how it breaks down, I care about what comes out of my pocket!

Sounds reasonable, the rest is just bureaucracy.

just a note about the nickel consumption in the Rossi process - Max 
quoted 1kg/6 months for the demo reactor - the figure given by Rossi 
is closer to 100g/6 months for a 10 kW reactor. I've also seen that 
quoted as low as 65g

im using the hash-a-pass concept and i even wrote a rebol implementation 
for it:

Very nice Tamás. But shouldn't 'paste have a different name, based 
on what it does? 'Paste implies taking data out of the clipboard 
and putting it into a target location. I know 'copy is taken though.

When I first saw it I was thinking that they put the wrong USB port 
on it (device rather than host) but figured that they wouldn't have 
made a mistake like that. Seeing the in-use pictures though, they 
did do that, which is why they have to hack up their own USB cables. 
USB's asymmetry can be lame sometimes.

As it "is designed to plug into a TV" that's most likely intentional.

It is designed to plug into a TV through HDMI, not USB. More likely 
it is because this platform is apparently designed for educational 
use, and is programmed by plugging it into another computer as a 
USB device. At runtime it changes the USB port to host mode, though 
not the USB plug. Perhaps they expect it to spend more time being 
programmed than used.

  All asymmetry is lame.  Even power cords, video cords, etc.   All 
  ahould have the same device on both ends.
