The topic is as interesting as the title.
After decades of effort, Scientists have
devised a way to generate electricity from
brain. Researchers from Massachusetts
Institute of Technology (MIT) have
designed an implantable fuel cell that can
generate electricity from a fluid around
the brain (cerebrospinal fluid). The result
of the experiment was a success since it
produced a few hundred microwatts of
power from glucose within the
cerebrospinal fluid. No adverse
physiological effects have been reported
so far. This small amount of generated
power is of course not enough to run a
small fan or any small appliance. But the
inventors are not thinking of utilizing this
energy to power the appliances. Instead,
scientists have planned to make use of
this energy in bio-medical field. The
amount of electricity produced is enough
to power the latest, futuristic and highly
efficient brain implants that can help the
paralyzed patients to move their limbs.
According to the team leader and
computer scientist Rahul Sarpeshkar, the
new fuel cells can be a great remedy for
paralysis or blindness. Currently, most
brain implants are powered through
inductive power transfer. The power is
transferred either wirelessly or by single
use batteries. The major disadvantage of
such single use batteries is that they have
to be replaced surgically after several
years. In comparison, the new fuel cell is
made up of platinum (a metal that has
good track record of being safe in human
body). Moreover, according to Rahul
Sarpeshkar the new fuel cell can work for
decades with no need of replacement.
These new cells will first be tested on
humans and animals.
This new fuel cell functions by oxidizing
glucose from cerebrospinal fluid at the
surface of an activated platinum anode
and then converting oxygen to water at
the surface of a network of single walled
carbon nanotubes embedded in the
cathode end of the cell. The fuel cell also
utilizes an oxygen gradient to prevent
oxygen from reaching the anode and thus
possibly creating electro-chemical short
circuits. Researchers have also conducted
tests to ensure the rate at which
cerebrospinal fluid glucose is replenished.
The results are satisfactory which means
that the method of generating electricity
is safe and has no adverse
effects. Furthermore, the fuel cell’s
oxygen consumption was also checked to
make sure that it wouldn’t destabilize
oxygen levels in brain.
Though it is still in prototype phase, it
sounds promising and efficient. Indeed it
would be a great invention to help
paralyzed people to live and enjoy life in a
better way. Below is a video of how it can
be utilized.

Light bulb!



Some are brighter than others.


If this is really effective, then the whole SW Nigeria can light up Nigeria.

Hehehehehe.... Seminar Organisers should not hear this.......

"CHILDISH"

Interesting.

Here is a party trick I have used a few times in the past. Mind you, I have probably lost a few brains cells in the process

Mr. Pozar explains, “You are capacitively coupling the fob to your head. With all the fluids in your head it ends up being a nice conductor. Not a great one, but it works.” Using your head can extend the key’s wireless range by a few car lengths.

This will be good enough to differentiate the dull and wise ones. Cos when you see a full bulb, you know the person is retarded and no need of wasting your time on the person.

Wishing it will also be extended to nairaland contribution.
