Let me start by wishing all readers good health and
patience in the human struggle with the coronavirus
pandemic. We wish it were not in our environment.
Now that it is we need to work together to survive
We each have struggles each day. Face them and
overcome them. We are scientists and technologists,
all. Let me tell you what I faced this morning with
my laptop, quarantined at home like many others. I
was perusing the news and mail and regularly visited
websites this morning when I noticed my lithium ion
battery was getting low state of charge signals. I had
the charger cord plugged in. What was going on?
This battery was replaced two months ago with an unused
one online, not from Dell (They only sold “refurbished”
batteries for this laptop.); it was installed guided by a
you-tube ‘how-to’ video and has been working nicely.
What to do? Go on line and see what others have
faced and done, right! Accordingly, I opened the
computer up to wipe the electrodes clean. While it
was sitting on my lap, I look down and the power cord light
was not lit. the plug had loosed from the socket and was
the root cause.
Lesson: Look for root causes of problems before you go
Electrochemistry in Space
The latest issue in “Interface
” brings us incredibly
thought-provoking articles that should move you to
take several looks.
The first uses the technology of ‘regenerative fuel cells
to explain the details of and action items included in
NASA patent of the utility patent US 7,410,714,
K. A, Burke.
[For all interested in a terrific series of technology
patenting please see
Cordeiro and colleagues show photos and descriptions
of a variety of sensor systems
Bugga and Brandon nicely review the history of
that find their way into the decades
of space programs and pointing out the need for
“beyond lithium” technologies
This is strongly recommended reading for people
interested in the science as well as future career
