waterfall, which looks cool, </font>they used Calcium Chloride,
which is not very effective. It should work (never saw and results)
but corrosion of components in and near the system is a challenge
for long term as CaCl is very corrosive. The energy required to
pump large volumes of liquid around need to be carefully managed, as
does heat gain from the warm recharged dessicant to be able to have
a lower energy use than current best in class dehumidification. But
it looks cool.<br>

<div>No experience with this myself, but I've always
thought this an interesting way to deal with human comfort
in hot/humid climates. I've seen commercial dessicant
wheels, but not ones made for residential purposes. The key
(enviro wise) is how you dewater the wheel. Waste heat would
seem a likely source. </div>

Has anyone experimented with the powder desiccants on
rotation?
<div>Say have two trays and when one is in the house getting
wet the other is outside on a south wall protected from
the rain drying out.</div>
<div>Would you need too much of it to make it effective, and
thus render it impractical?</div>
