** Economic data has accelerated stronger in
recent months with the U.S. and Europe leading
the pack.
What Does The Stock Market Say?
This is just the beginning of effects to be felt from
the new demographics boom. Based on today¡¯s
headlines fearing market tops and imminent
crashes around every corner, it is not clear
whether the mainstream media has considered de-
mographics data at all.
Just as in August 1979,
when Business Week
declared ¡°The Death
Of Equities¡±, history
seems to be repeating
itself.
Consider the featured
chart on the front page, from Chris Ciavacco,
which shows that, despite all the media talk to the
contrary, the stock markets have been in sideways
consolidation for about 17 years. As it was also in
1979 when gloomy headlines were the norm.
The current breakout from the nearly two decades
long consolidation box is quite obvious, and is con-
firmed by the economic data currently available.
As always, past performance is no guarantee of
future results so one must remain open and
flexible to changes in the data, however the
probability for the new uptrend to continue for
several years, based on both historical and current
data, is high.
¡°When a market makes a historic high, it is telling
you something. No matter how many people tell
you why the market shouldn¡¯t be that high, or why
nothing has changed, the mere fact that the price
is at a new high tells you something has changed.¡±

Demographics To Fuel Growth

traditional phase change materials, or, ¡°little
molecules that undergo a structural change
when light shines on them.¡± The trick was to find
a way to integrate these molecules with con-
ventional PCM materials to release the stored
energy as heat, on demand.
¡°There are so many applications where it would
be useful to store thermal energy in a way that
lets you trigger it when needed,¡± he says.
The researchers accomplished this by combining
the fatty acids with an organic compound that
responds to a pulse of light. With this arrange-
ment, the light-sensitive component alters the
thermal properties of the other component,
which stores and releases its energy.
The hybrid material melts when heated, and
after being exposed to ultraviolet light, it stays
melted even when cooled back down. Next,
when triggered by another pulse of light, the
material resolidifies and gives back the thermal
phase-change energy.
¡°By integrating a light-activated molecule into
the traditional picture of latent heat, we add a
new kind of control knob for properties such as
melting, solidification, and supercooling,¡± says
Grossman, who is the Morton and Claire Goulder
and Family Professor in Environmental Systems
as well as professor of materials science and
engineering.
The system could make use of any source of
heat, not just solar, Han says. ¡°The availability of
waste heat is widespread, from industrial pro-
cesses, to solar heat, and even the heat coming
out of vehicles, and it¡¯s usually just wasted.¡±
Harnessing some of that waste could provide a
way of recycling that heat for useful applications.
¡°What we are doing technically,¡± Han explains,
¡°is installing a new energy barrier, so the stored
heat cannot be released immediately.¡± In its
chemically stored form, the energy can remain
for long periods until the optical trigger is acti-
vated. In their initial small-scale lab versions,
they showed the stored heat can remain stable
for at least 10 hours, whereas a device of similar
size storing heat directly would dissipate it within
a few minutes. And ¡°there¡¯s no fundamental
reason why it can¡¯t be tuned to go higher,¡± Han
says.
In the initial proof-of-concept system ¡°the tem-
perature change or supercooling that we achieve
for this thermal storage material can be up to
10 degrees C (18 F), and we hope we can go
higher,¡± Grossman says.
Under a dark-field microscope, the microscale
environment shows the rapid crystal growth can
easily be monitored. (Grossman Group at MIT)
Already, in this version, ¡°the energy density is
quite significant, even though we¡¯re using a con-
ventional phase-change material,¡± Han says. The
material can store about 200 joules per gram,
which she says is ¡°very good for any organic
phase-change material.¡± And already, ¡°people
have shown interest in using this for cooking in
rural India,¡± she says. Such systems could also
be used for drying agricultural crops or for space
heating.
¡°Our interest in this work was to show a proof of
concept,¡± Grossman says, ¡°but we believe there
is a lot of potential for using light-activated ma-
terials to hijack the thermal storage properties of
phase change materials.¡±
¡°This is highly creative research, where the key
is that the scientists combine a thermally driven
phase-change material with a photoswitching
molecule, to build an energy barrier to stabilize
the thermal energy storage,¡± says Junqiao Wu, a
professor of materials science and engineering at
the University of California at Berkeley, who was
not involved in the research. ¡°I think the work
is significant, as it offers a practical way to store
thermal energy, which has been challenging in
the past.¡±

for Technology and Design within MIT¡¯s Energy
Initiative.

A New Way To Store
Thermal Energy
MIT researchers create material
for a chemical heat ¡®battery¡¯
that could release its energy on demand
November 16, 2017: In large parts of the devel-
oping world, people have abundant heat from the
sun during the day, but most cooking takes place
later in the evening when the sun is down, using
fuel ¡ª such as wood, brush or dung ¡ª that is col-
lected with significant time and effort.
Now, a new chemical composite developed by
researchers at MIT could provide an alternative.
It could be used to store heat from the sun or any
other source during the day in a kind of thermal
battery, and it could release the heat when need-
ed, for example for cooking or heating after dark.
A common approach to thermal storage is to use
what is known as a phase change material (PCM),
where input heat melts the material and its phase
change - from solid to liquid - stores energy. When
the PCM is cooled back down below its melting
point, it turns back into a solid, at which point the
stored energy is released as heat.
There are many examples of these materials, in-
cluding waxes or fatty acids used for low-temper-
ature applications, and molten salts used at high
temperatures. But all current PCMs require a great
deal of insulation, and they pass through that
phase change temperature uncontrollably, losing
their stored heat relatively rapidly.
Instead, the new system uses molecular switches
that change shape in response to light; when inte-
grated into the PCM, the phase-change tempera-
ture of the hybrid material can be adjusted with
light, allowing the thermal energy of the phase
change to be maintained even well below the
melting point of the original material.
The new findings, by MIT postdocs Grace Han and
Huashan Li and Professor Jeffrey Grossman, are
reported this week in the journal Nature Commu-
nications.
¡°The trouble with thermal energy is, it¡¯s hard to
hold onto it,¡± Grossman explains. So his team de-
veloped what are essentially add-ons for
