[Vwdiesel] A paste of Roger's Hydrogen post....

[Mark Shepherd]

Here is a slice of Roger's hydrogen link. Funnily enough I
was reading a book about this only a few days earlier...
I'll post a snippet at the end of this excerpt...

Metal Hydride Tanks
Metal hydrides are specific combinations of metallic alloys
that act similar to a sponge soaking up water. Metal
hydrides posses the unique ability to absorb hydrogen and
release it later, either at room temperature or through
heating of the tank. The total amount of hydrogen absorbed
is generally 1% - 2% of the total weight of the tank. Some
metal hydrides are capable of storing 5% - 7% of their own
weight, but only when heated to temperatures of 2500 C or
higher. The percentage of gas absorbed to volume of the
metal is still relatively low, but hydrides offer a valuable
solution to hydrogen storage.

Metal hydrides offer the advantages of safely delivering
hydrogen at a constant pressure. The life of a metal hydride
storage tank is directly related to the purity of the
hydrogen it is storing. The alloys act as a sponge, which
absorbs hydrogen, but it also absorbs any impurities
introduced into the tank by the hydrogen. The result is the
hydrogen released from the tank is extremely pure, but the
tank's lifetime and ability to store hydrogen is reduced as
the impurities are left behind and fill the spaces in the
metal that the hydrogen once occupied.

Carbon nanotubes
Carbon nanotubes are microscopic tubes of carbon, two
nanometers (billionths of a meter) across, that store
hydrogen in microscopic pores on the tubes and within the
tube structures. Similar to metal hydrides in their
mechanism for storing and releasing hydrogen, the advantage
of carbon nanotubes is the amount of hydrogen they are able
to store. Carbon nanotubes are capable of storing anywhere
from 4.2% - to 65% of their own weight in hydrogen.
The US Department of Energy has stated that carbon materials
need to have a storage capacity of 6.5% of their own body
weight to be practical for transportation uses. Carbon
nanotubes and their hydrogen storage capacity are still in
the research and development stage. Research on this
promising technology has focused on the areas of improving
manufacturing techniques and reducing costs as carbon
nanotubes move towards commercialization.

My reading reveals:
heated platinum can absorb 4 times its volume of hydrogen
heated iron 0.44 x
heated silver 1 x
BUT
Palladium can 'occlude' 980 times its own volume of hydrogen
gas; giving an increase in its own volume of 1.09827
times... or in other words the effective density of hydrogen
gas becomes 9868 times as dense... or in other words 0.88 x
the density of water (compared to  0.000089546 x   for
hydrogen gas)or basically liquid hydrogen at NTP...

Hmm I'm thinking I've stumbled upon something that could
somehow be used to power a hydrogen car. Could this be a
missing link to how those few people like Meyer and Dingle
have allegedly managed to create their water electrolysis
cars? Especially if there is something in the theory that
there is at least one frequency that can break water down at
an energy efficiency greater than 1...
