The endless potential of Concrete


Moving on from Proof of Concept

I have settled on the concept of a seated area heated that is heated from an electric power source. I believe that the proof of concept showed me that trying to have a self sufficient chair, while possible, wasn’t practical or particularly efficient at attaining power. I do believe that have an external power source does not mean that the product will be using an inappropriate use of electricity and it would be up to the public area to be responsible for where the electricity comes from. The product will be environmentally responsible as it will only take 30 mins of electricity which will take a little over the power consumption of a hair dryer. the following posts will be focused on aesthetic development and will combine with the technical heating of the product again as the product reaches a final design.

Testing Chair.

In the week leading into our proof of concept deadline, people were working in the studio late on cold nights. I decided to put the chair into the smoking area and allow people to use it and evaluate the heating source. although it wasn’t a comfortable shape, it did prove to be surprisingly warm and comforting to sit on.

I added the insulating blanket to help and retain the heat when people were not sitting on it and also to act as an extra comfort while using it.

Making a Working Model

For the last month I have been making this working model to prove the idea that a heat seat which retains the heat through natural heat sink (in this case the tile, which aren’t as efficient) will provide adequate comfort over a long period of time with a short heating period.

IMG_0514The frame was first made, and heating wires from an electrical blankets were set out onto the seated surface.











Insulation was then used to force the heat towards the seated surface and heat sink.











IMG_0516Reflective tape was used to further insure that the heat would be directed towards heat sink.











IMG_0517The wires from the blanket were then relaid over the reflective surface.










IMG_0527A hole was cut in the back of the chair where the plug for the blanket wires would go.

Quinn Light

Quinn Concrete have developed a lights weight concrete with high insulation value. This could be an interesting material to use in some areas of the chair to keep weight down.

Testing heat sink and sources

Below are a series of small projects undertaken to try and evaluate some potential heat sources and heating methods. these include a simple solar panel made from an old refrigerator radiator, a water heated concrete heat sink and an electrically heated concrete heat sink. Issues with water freezing if left outside unheated for large periods of time is a concern made more evident after these tests.

Sketchbook 3 Round Up

Most of the drawings developed in January can be seen below but there were a few other areas explored with a brief round up below.
