Not necessarily doubting, but was that
"stores", or "can store"?
Many years ago, I attended a presentation about a holographic
system the "could store" MANY gigabytes per cc. The phrase
"can store" was used a lot. When asked about current progress,
they were VERY evasive. After about a dozen questions, they
admitted that they had not yet achieved the multi-gigabyte
capacity. After many more questions, they finally admitted
that the current capacity was 27 bits. It is a good proof of
concept, but the differentiation between projection and
accomplishment is significant.
'course by now, they very well might have reached the
capacity goals.
Well, as it looks, the Stuttgart people already store (and
retrive) a terrabyte (1000 Gig) in a 1 cm^3 cube. So the scale
might be right.
Similarly there is a proponent of alternate fuel
vehicles who
is constantly quoting specs that include impressive results.
He is very evasive about timeframe of availability.
But it turns out that his vehicle is NOT in production.
There isn't even a prototype! His "data" is all results
of "simulations", and many of his "can do" numbers require
a complete restructure of society. Even when explicity
challenged, he adamently refuses to acknowledge a difference
between possibilities and existence.
*G*
I'm already happy with what's available. As for myself I'm a
hugr fan of the hybrid idea, but in reality, modern Diesel
engines are at least at the same level of fuel efficency if
not ahead. Meredes is even working on a large Diesel hybrid,
but then again, I can't afford Mercedes prices :(
