Biography

Since obtaining PhD in Electrochemistry in 1994, I have been through many things, such as post-doctoral research work using STM to study atomic level electrodeposition of Cd on Ag(111) surface at UIUC (Urbana-Champaign at University of Illinois), lifetime free-lance preaching, CEO of TheoLogos Publications and 014599190 Global Inc, former salesman of diamond tools for Superprem Industries, former CEO of DiaSolid Kitchen & Bath, finishing carpenter, working for CRE Green, a solar company in Kelowna, BC. Now I have started this new business manufacturing and distributing PyraPOD. After all these experiences, my life motto is this: sharp mind must combine with skilful hands. With my wife Margaret we have three kids - Riley, Grace and Anita.

Building a Bubble Lighthouse to demonstrate how to use Soap Bubbles to capture solar thermal energy

Building a Bubble Lighthouse to demonstrate how to use Soap Bubbles to capture solar thermal energy

This idea spins out since we had a breaking in making PyraPOD by using a CHIMNEY as both the bubble generator and the inner skin. This way we can use ONE layer to cover it and form a double-layer cavity in between. The following video explains the concept:

The following video showing the first stage of this little project - it shows the success of producing a lot of soap bubbles using two HomeDepot pails:

Then the final success - after total filling with soap bubbles, the bubbles are still there after 6 hours (later tests show I still see some bubbles after 10 hours!):

What I do next? Do a comparative study between two Bubble Lighthouse - one insulated with air only and one with soap bubbles:

PyraTUNNEL: all in one design and build to include SolaRoof BubbleTech and iAVS sandponics

While I have left Redwater Alberta and leave for Angus the owner to finish the foundation for continued work next spring, the Montreal team is working on a similar design with almost no digging (only two small pits to bury the soap reservior and the barrel to collect water condensate). Now they have erected the truss and finish certain parts of the four A-frames - take a look:

PyraTUNNEL: all in one design and build to include SolaRoof BubbleTech and iAVS sandponics

I had rash all over my body on the Calgary site. So I had to switch site. Now I have moved to a site north of Edmonton, which is colder than Calgary. This Dixon Model combines everything in one design to face the hush challenges we have on the building site: no power, no water, no shelter, only an empty farmland with hay uncut.

This new building site is located in Redwater, AB, Canada, which belongs to the Sturgeon County in the province of Alberta. This drone video shows the building site in more detail - it also shows two large solar panels to charge a 3 kWh power unit and a RV trailer (with the fridge turned off, I have enough power to use, even during cloudy days):

PyraTUNNEL: all in one design and build to include SolaRoof BubbleTech and iAVS sandponics

Richard Nelson and I have planned for this project for a month or so. Please check this YoutTube channel playlist above for all the info.

To build this project, I have travelled from Kelowna BC to Calgary AB. The digging has been scheduled for this coming weekend - September 10 and 11. If you happen to live around this area, please come and have fun digging the top soil.

I have also set up a GoFundMe link for this project: GoFundMe for this PyraTUNNEL project

Have fun building this new type of greenhouse to raise fish and grow vegetables in winter!

Solar water heater in Greenhouse

Jared Van Denend wrote:We are building a high tunnel in WA (zone 7b). The main purpose of the high tunnel is to get a whole bunch of starts rocking early spring... however if it is there we would like to grow whatever we can in it all winter. So we are looking at heating options.

We are going to build cold frames inside the greenhouse which we will remove and place over some beds in the spring. This got me to thinking if every layer of greenhouse material bumps the zone up... how about a solar water heater inside of a greenhouse.. heating up our barrels.

Has anyone done this? I know theoretically it should work, but I'm wondering if the juice is worth the squeeze. I haven't found any info about this type of setup on the web.

Beside heat storage, there is another side, that is the insulation property of your greenhouse. I have tried everything I could think of. To cut the story short, Richard Nelson's SolaRoof approach is the best. This system is basically a double layer greenhouse, creating a cavity that we cool it in summer time by spraying water in there and keep it warm in winter by filling the cavity with soap bubbles. That's it. We cannot find any other system that is better than this. Period.
