Work in Progress!

Working title: "April 6, 2012 - Information about Biophotovoltaics coming soon!"[ https://biophotovoltaics.wordpress.com/ ]

Intro

During a course the student visited the exhibition "Bio Design" in the New Institute in Rottedam.[1]
In a following course a student has been working on the design of a paviljon for a square in Rotterdam. She discovered that the square is covered with moss. She makes the connection with the Cambridge Moss Table [2] which was on display in "Bio Design". Based on this table, she calculated that around 12 square meters of moss were needed to illuminate the paviljon during the night.

What is the Cambridge Moss Table?

This table is designed by a team of designers and scientists at Cambridge University[ ]. It is called a prototype table and a showcase of emerging technology[ ]. Although the setup is not producing enough energy to power the lamp incorporated in the design in 2011 the technology is forecasted to be competitive with the solar cell within 5-10 years [3].

About the predictions

"Currently, the moss generates about 50 milliwatts per square metre (mW/m2). Scientists anticipate that future devices may be able to generate up to 3W/m2 (Strik at al., 2011). "[4]

About the calculations

Each one generates a potential of about 0.4-0.6 volts (V) and a current of 5-10 microamps (µA).[5] In a comparable article [6] on BPV is briefly mentioned: "voltage and amperage were measured in all the experiments, and even though voltage was always present, no amperes were observed.".

Design

Description of the table
A design table with moss plants nicely arranged in the table top. A table light is part of the table. The legs and the frame of the table are indistinguishable from a basic camping table. The design contribution is in the way the moss plants are growing under a glass table top and the way the table light is added in the circular shape. The nicely arranged fresh moss plants under the glass are very appealing for the eye.
