I live in Victoria Canada. I trained as a lab technician but I couldn't stand how regimented it was. I like to do hobby research. and I invented the pulser pump. (or maybe not). I have promoted it with very limited success for 20 years. I was nominated for the Ars electronicia next idea prize (Linz Austria) in 2011 for the pulser pump.

I am currently trying to get people interested in "nano" airlift pump research. This is an offshoot from my pulser pump work and from "windowfarms". The research that is needed is very cheap to do.

In solar cooking, I made the mechanical mathematician (A low tech way to make a mold for parabolic dish solar cookers). I used it in my first attempt at a tracking solar cooker. For that project I also made the clock based dripper tracker and the waterclock dripper tracker. I won a prize in an "instructables" competition for the clock based dripper tracker. A higher tech version of the dripper trackers called the liquid piston tracker was "perfect" for the mecatronics course in University of Victoria but was then rejected as a student project because I am not a company.

I came up with the "dual dish" parabolic solar cooker in late 2009 while suffering from pneumonia. This one uses 2 half parabolic dishes on equatorial mount (to counterbalance each other) and is as yet untested. Astronomers have said that the overall idea is correct with physics. (They track the sun in the same way).

The dual dish parabolic should be much easier to use than a typical full dish parabolic solar cooker because daily adjustment is just a simple rotation of the dish.

The solar design T-square is my other contribution. Basically you mount a laser level above your design indoors and use the laser light bouncing from the mirrors it to adjust your mirrors etc. You can use it to design a parabolic dish and you can also use it to design a solar cooker for unattended use. This is how the clam shaped solar cooker came up.

I think people who adjust their mirrors outdoors (under a hot moving sun)! are making things very very hard for themselves but as yet people seem reluctant to try the easy way.

The other thing is that I found and used software to help with the design process. I used the art of illusion software program. This is a free program that will work on any computer with java. I have used it on windows and linux on a desktop, laptop and on a netbook.

I am useless with computer stuff but even so this helped greatly. If a decent computer geek did a little work with art of illusion they could produce a downloadable sun engine "scene file" . You can then put your solar cooker in the scene file, adjust it in different ways and see how it performs.

The dual dish solar cooker (just a model) was in the arts and science fair in Toronto in 2010. They accepted it and the solar design T-square as additional projects in the ars electronica competition too. (2011) (A nominee can enter several projects).

I am a stonemason, my work time and best solar cooking time are the same. I have to work to make a living so I do very little actual solar cooking.

Some people have used that to put me and "my" ideas down. All the ideas are community commons lisensed so they are everybodys. It is terribly dissapointing that so few people look at them rationally.

Other than rock walls, I am not much good at building things but if people look I think they will find the concepts are soundly based.
