Rubus chamaemorus is called 'bake apple' in Newfoundland.
The myth(?) is that a French colonist asked
'Baie, Qu'Appelle?'  ('Berry, called what?)

In Sweden they are sold in plastic bags of mushed berries & juice;  I heard they have natural anti-fungal properties so do not go mouldy.

I find them frustrating to pick; one big leaf, one berry per shoot, but will throw them in with blueberries or lingon if I find them.

I agree with David.
The market is changing quickly.
3 years ago we installed grid-tie solar in Nova Scotia with 1:1 kWh exchange with the utility; send a kWh on a sunny day, take a kWh in the dark.
At the end of the year any positive balance in our favour is zeroed out.
So 3 years ago our system was sized at ~85% of our consumption, to avoid 'losing' power to the utility.
But today my neighbour's new system is sized at 101% of consumption, because panels are so cheap that 'losing' a few percent to the utility is negligible.
10 of 36 houses in our little neighbourhood now have grid-tie installs, with a payback of ?8-9? years.

5 years ago in New Brunswick the deal was similar, except the utility sold us power, charging tax, but forced us to pay the 'tax' to return power to them.  15% each way made the deal less favourable.
As batteries drop in price, total offgrid becomes progressively more attractive.

Hi
Rugosa roses are salt tolerant; some strains grow to 2 m, and fruits are comparable in size to crabappples.
Not useful for apple pollenation though.

Warming up pond water might lead to ghastly pathogen proliferations.

Hi - if the glass jar is on a vent tube, what is the purpose of the two black elbows beside it?
thanks Doug

Hi Lala
What is the glass component behind the seat?
thanks Doug

I built a roundwood woodshed last year of similar scope, to try out approaches.
I followed ideas from https://www.youtube.com/@KrisHarbour
on how to layout joints for curving pieces; it worked fairly well.
I cut lap joints at the tops of the main posts, with natural forks as knee braces.
On a different thread I read an expert writing that knee braces are not necessary, but they certainly stiffened my structure.
The post ends are under a metal roof so I did not attempt preservation beyond linseed oil.
I used timbers end-to-end through the concrete block holes, and recycled cabling,  to use the weight of the firewood load to anchor the structure and roof to the ground.
It has come through its first winter fine.

My next project is actually a honeysuckle arbour.
cheers Doug

Old post.
This is interesting as a science project or for value added products,  but not for renewable energy.
The Energy Return on Investment is too low.
Photosynthesis:

CO2 + H2O + 10 photons captures -> CH2O + O2

Maximum known conversion is ~4% for Brazilian sugar cane (interestingly, some lines can also fix N2 using symbionts)

Algal bioreactors have lower conversion rates, ~1%,  partly b/c light is attenuated by the cell suspension.

PV solar panels run at ~23% conversion, do not require water etc.
Then the electricity can be used at ~80% conversion to useful work.
Burning fuel is a maximum of ~30% conversion to useful work.

PV wins, electric wins by 100x, as Dale wrote regarding tool use.

Photosynthesis:
100 photons x 0.01 x 0.3 ~ 0.3 photons of work.
vs

PV
100 photons x 0.23 x 0.8 ~ 28 photons of work.

And the PV system is cheaper, lower maintenance and less prone to failure.

Steve Zoma wrote:use plywood gussets to fix the braces together. That way the angles would be perfect, and then just nail the braces to the hexagonal plywood gussets.

Agreed!
But would plywood gussets work with roundwood?  Attachment surfaces to members would have to be flat.

Hi;
Interesting build.
I just did a rough, guesstimate on my (new) materials cost to build something similar:
$C3088
Scavenging would lower some costs, but takes time in a low population area; stainless steel barrels are not common.

I  wonder about the space; from the video it seems the installation + offsets takes about ?3' x ?10' which seems a fair share of the tiny house.

Estimates (in Canada, we still use imperial for building supplies.):
Stainless steel barrel, 50 gallon, $C1250 (ULine.ca)
8" stove pipe (black), $C23/18" x ~30'/1.5' ~ $C460 (HomeHardware.ca)
6" stove pipe (black) $C24/36" x ~ 10'/3' ~ $C80 ((HomeHardware.ca)

8" stove pipe take outs $C57 x 3 = $C171 (HomeHardware.ca)
8" stove pipe elbows $C25 x 2 = $C50 (HomeHardware.ca)
6" stove pipe elbows $C20x 3 = $C60 (HomeHardware.ca)
6" to 8" stove pipe increaser $C29 = $C60 (HomeHardware.ca)
8" rain cap $C37 (HomeHardware.ca)
Aluminum foil tape ~ $C24 (HomeHardware.ca) (adequate?)

SteelSheet 24GA 0.024 $C0.03/sq inch x (48" x 24") x 2 ~ $C69 (metalsrus.ca)
(There may be cheaper appropriate heat shield materials?)
Pea gravel x 0.24 yard ~ $C30

Uninformed guesstimates on quantities
2" thick 2600F wool forge liner 12 sq ft $C216 (https://canadianforge.com/)
9" x 4.5" x 1.25" firebrick $C9 /each X ?20? $160 (kent.ca)
2" x 4" x 8" brick $C3.33/each x ?100? = $C333 (kent.ca)
2" x 4" x 96"  lumber $C4.4 each x ?20? = $C88
