Episode 148
Time-Tested Technology and Reviving Ancient Wisdom for Modern Sustainability
Episode Summary: In this episode of CarbonSessions, hosts Leekei, Jenn, and Kristina dive into the fascinating world of ancient low-tech solutions being reimagined for modern environmental challenges. They explore how businesses are harnessing time-tested technologies to create sustainable solutions for today's world.
Key discussion points include:
- Reviving Ancient Maritime Techniques: The hosts discuss the innovative use of "wind wings" on cargo ships, a modern twist on traditional sails, to reduce reliance on fossil fuels.
- Simple Pleasures of Snail Mail: The conversation shifts to the joys of traditional letter writing, specifically a service that sends story chapters via snail mail, fostering connections and sparking imaginations in a low-tech manner.
- Sustainable Milling Practices: They explore the revival of water-powered mills with stone grinders in the Czech Republic, celebrating the unique taste and nutritional value of traditionally milled flour.
- Solar-Powered Bakeries: Highlighting a bakery in Normandy that bakes bread using solar energy, the hosts discuss how this eco-friendly approach is spreading across France.
- Baby-Led Weaning: The discussion turns to the trend of baby-led weaning, where infants transition directly from breast milk or formula to real food, bypassing the need for processed baby food.
Through these examples, the episode showcases how blending ancient wisdom with modern innovation can lead to environmentally friendly and sustainable business practices.

Hi, I'm Christina.
2
:I'm from Prague.
3
:Hi, I'm Jen, and I'm from Canada.
4
:Hi, I'm Oladunji, and I'm from Nigeria.
5
:Hello, I'm Liki, and I live in Paris.
6
:Hi, I'm Brian, and I'm from New York.
7
:Welcome to Carbon Sessions.
8
:A podcast with Carbon Conversations
for every day with everyone
9
:from everywhere in the world.
10
:In our conversations, we share ideas,
perspectives, questions, and things we
11
:can actually do to make a difference.
12
:So don't be shy and join our Carbon
Sessions because it's not too late.
13
:Hi, it's Nikki.
14
:Hi, it's Kristina.
15
:Hi, it's Jen.
16
:. Today we're going to talk about something.
17
:Wow.
18
:I think it's fascinating.
19
:, the other day I was listening to the
radio and I heard someone, some, some
20
:journalist talking about hydrogen
and , the journalist seemed to be
21
:very, very excited about hydrogen.
22
:But then.
23
:Then someone said, yeah, but you
know, it's not that we don't have the
24
:technology to solve climate change
or to be better with the environment.
25
:Almost everything is here.
26
:And it's just that we don't have the
will or we don't want to transform the
27
:way we've been living up until now.
28
:And so that's why I suggested this
conversation on businesses that are based
29
:on an ancient technology, uh, something
like low tech or like something that, that
30
:is so obvious that has been used for ages.
31
:It doesn't pollute a lot and that
we could do incredible things.
32
:And we're going to talk about
these incredible businesses that
33
:have based their business on this
ancient low tech technologies.
34
:Who wants to start?
35
:I can start.
36
:Great.
37
:Okay.
38
:So, I have two.
39
:One of them is really big, and
one of them is really little,
40
:in all senses of the words.
41
:The first one is that I just found out
about recently is that cargo ships.
42
:are playing with, experimenting with,
going back to putting sails, S A I L
43
:S, on their ships, and they're calling
them wind wings, and they don't look
44
:like the, the cloth sails, they're
kind of like an inverted airplane wing
45
:with the flaps, they're, they're metal.
46
:But instead of using coal and,
and fuel, fossil fuels, they're
47
:going back to the ancient way that
ships used to sail across the sea.
48
:And 90 percent of the stuff that's
sent overseas is sent by ship.
49
:And so this is amazing.
50
:And there are actually companies that
have been testing this and thinking
51
:about this since 2010, I found out.
52
:But next year, there are, uh, some
things in place regulation wise,
53
:and they're going to be measuring
the fuel use, et cetera, and they're
54
:going to be testing with these wings.
55
:So it's pretty cool and exciting.
56
:And if you look it up online, um, NPR
and BBC and a whole bunch of places have
57
:photographs of these ships with these
vertical, uh, wings, like, um, uh, sort
58
:of like big steel panels with flaps.
59
:That act as sails so that they
can use less power or no power at
60
:some points and, and pick up the
wind, uh, the way it used to be.
61
:So that's really cool.
62
:That, that's really cool, but I find it
very weird to call it to sail cargo ship
63
:because when you mentioned sail, you
know, what I picture is the big, big, big.
64
:Close white cell, like sailboat, . But
yeah, I saw, yeah, I saw a picture of it.
65
:They actually look like, uh,
like smokestacks or something?
66
:, yeah.
67
:Like only the, you know
the, it's a sailboat.
68
:Yeah.
69
:Without the cell.
70
:Only with the mask, you know,
with the st, yeah, yeah, yeah.
71
:But wide.
72
:So really cool.
73
:So that's my first thing.
74
:And the second thing I came across
recently that I would love to do
75
:with my grandson, but he's not big
enough yet, so I have to wait till.
76
:He can read, which he's, you know, he's
two and he's already knows his numbers
77
:and letters backwards and forwards.
78
:But anyway, I have to wait
for a little bit longer.
79
:I discovered a company that you
can sign up for and they will
80
:send, uh, a letter twice a month,
I think, to whoever you desire.
81
:And the letter is part of a story.
82
:And you open the letter, it's
paper, and it's beautifully
83
:illustrated, and there's a story.
84
:And the idea is that you can then connect
with the person who bought this for you.
85
:You could be miles and miles apart.
86
:and talk about the story and
wonder what's going to happen next.
87
:And every couple of weeks,
a letter comes in the mail,
88
:like old fashioned snail mail.
89
:And, uh, and it's just a delightful,
simple, old fashioned way.
90
:Um, inspiring imagination and, um,
and it's an activity for a child
91
:that doesn't require batteries.
92
:It isn't plastic, you know, and I thought
this is wonderful because we often don't
93
:get things in the mail anymore and how fun
for a child to get something like that.
94
:So I love this idea and I can't wait.
95
:So how does it work?
96
:Because you say that enables
, the kid to connect with the
97
:person who send the snail mail.
98
:So does it mean that you're going
to do it for your grandson?
99
:And then it's a way for your
grandson to connect with you?
100
:Yeah, it's just that the company
is the one like you buy it and then
101
:tell them the person's name and
everything else, the child's name.
102
:And then the company sends.
103
:This basically like a
dripped out story, right?
104
:You get a little chapter of the
story sent and it gets mailed in a
105
:beautiful envelope that the envelope
is beautiful, the paper is beautiful.
106
:And it has the child's name on it.
107
:And then every time they get
one, you can read it together.
108
:You can talk about it on the phone
if you're not nearby, you know,
109
:like there's just a way to connect.
110
:And then, you know, you can talk
about the characters and wonder
111
:what's going to happen next.
112
:It's almost like reading a book together,
only it's over, I think, a year.
113
:It's, it's like a long
time that the person.
114
:Uh, that gets an envelope in the mail.
115
:I mean, you could do
it for any age, right?
116
:But it's just kind of a fun thing.
117
:I love this idea.
118
:It is actually something I
did for my nieces and nephews.
119
:What I try to do every time I go
on holiday on the place that is not
120
:very well known, like no, no, that
is not very well known, but not a
121
:lot of people go on holiday too.
122
:What I try to do is to buy postcards.
123
:, with a stamp and send it to my
nieces and nephews, because as
124
:you said, we don't receive a lot
of letters and things through the
125
:traditional snail mail anymore.
126
:And I, I love to do it.
127
:I mean, this summer I went to Latvia
and you probably , guess that not
128
:many people go on holiday in Latvia.
129
:So that was the perfect excuse
for me to send in a postcard.
130
:And I did for my niece's and nephew
and think it's very beautiful
131
:because my six year old niece
thought it was a great idea.
132
:And so, so then she started
writing postcards as well to all
133
:of us when she went on holiday.
134
:And so I think it's, it's, it's,
uh, it's a very nice circle.
135
:It's, uh, it's starting a new
tradition, which I think is beautiful.
136
:And it's another way of, you know,
having this conversation and connecting.
137
:Great.
138
:I have one, uh, story
about, uh, food, food story.
139
:They started in Czech
Republic restoring mills.
140
:That run on water and they have the
old stones instead of, um, metal
141
:grinders, they have stone grinders
and they can make flour from basically
142
:anything, wheat, corn, all of it.
143
:It's getting popular because it tastes
different and all the nutrients are
144
:there and they cannot melt too much.
145
:So they don't have much storage.
146
:And so shelf life of these
flowers are, uh, very short, but
147
:the flowers are delicious and
you don't use any electricity.
148
:For milling the flour.
149
:And so I thought that was a wonderful
way to do something old ways.
150
:Oh, that's beautiful.
151
:That's wonderful.
152
:I bet the bread tastes so
good made with that flour.
153
:Yeah.
154
:And it rises different than works
with the yeast much easier, faster,
155
:because it's real flour with all
the little microbes and everybody
156
:that are good for rising the bread.
157
:Yeah.
158
:You know what's funny?
159
:That makes me think of, um, that we
were given, uh, as a hand me down,
160
:a big machine that makes coffee and
cappuccinos and I can't remember what
161
:they're called, but this thing was the
size of the old computer stack, you know,
162
:the big, like it's a giant thing and
they, they handed it down because they
163
:had gotten a new one and gave it to us.
164
:Not something we ever would
have gone out and bought.
165
:And honest to goodness, it
was so difficult to use.
166
:You had to take it apart, you had
to decalcify it, you had to clean
167
:it, and it wasted so much coffee
because you ground the coffee and
168
:then it would, it would do its thing
and it would make you a cup, right?
169
:And this thing, it took up so
much space, it took up so much
170
:bandwidth because we would be so
frustrated trying to make coffee.
171
:And you know, we have one cup of
coffee a day and our usual way of
172
:making coffee is a French press,
which is very old fashioned.
173
:You put the coffee in and you let
it sit and then you push it, plunge
174
:her down and there's your coffee.
175
:Right?
176
:So we ended up actually giving this
thing to somebody else because we
177
:just couldn't handle it anymore.
178
:It was too fancy and it had too
many parts that didn't work every
179
:once in a while and it might break.
180
:And, uh, and it took up so much
space instead of this little bodum
181
:that we have that you can tuck away,
you know, and sometimes simpler and
182
:old fashioned is just dang easy.
183
:Amazing on these mills.
184
:Some of them are made out of wood
instead of metal, all those wheels.
185
:And everything is made out of wood.
186
:It makes me laugh when, uh, you go into
restaurants now, like we have a big coffee
187
:culture in my corner of the world, and
it makes me laugh when they talk about
188
:pour overs, they have this fancy new name
for what used to be the Melita, you know,
189
:used to put the thing in the top of the.
190
:And just pour stuff in or pour
it into a pot with boiling water,
191
:which is like the old fashioned way.
192
:And now they call it a pour over, which
is exactly the same thing from the
193
:1960s and 70s that they've gone back to.
194
:And now it's very she she in the
coffee shops to have a pour over,
195
:which is like old technology.
196
:I looked at it and I'm like,
they're not doing anything different
197
:than my mother used to do before
automatic coffee maker drip machines.
198
:Right?
199
:It's really fun.
200
:Yeah, I still remember my grandmother
just grinding coffee in a small hand,
201
:uh, grinder for coffee and then putting
it in a cup, pouring hot water over
202
:it, let it settle and then drinking it.
203
:No filters, nothing, just
pure coffee and water.
204
:And it did settle, surprisingly.
205
:And if plus the timing was
perfect because it was too hot
206
:when you pour it and Mixed it in.
207
:And when it settled, it
was perfect temperature.
208
:Exactly.
209
:Exactly.
210
:They were so smart.
211
:And it's kind of like old
fashioned bread making.
212
:You know, I had a bread maker for years
when my kids were growing up and yes, it
213
:was convenient and all the rest of it.
214
:But.
215
:Um, I started making bread when I was
11 and baked beautiful braided egg
216
:loaves and sour dough and stuff that
looked gorgeous cause it was fun.
217
:And it didn't take anything
other than, you know, salt,
218
:water, flour, and, and yeast.
219
:And it was so simple.
220
:And, and so, you know, I don't
have a bread maker anymore, but
221
:if I'm going to make bread, I want
to do it the old fashioned way
222
:because it always tastes good.
223
:Yeah.
224
:Oh, that's wonderful.
225
:Yeah.
226
:With bread making for me, I
couldn't bake bread that tasted
227
:good and had good crust in the oven.
228
:And finally, my friend showed it to me and
she baked it in a pot with a lid first.
229
:And then at the end opened the pot, it's
like, Oh my God, that's so brilliant.
230
:Finally, perfect bread.
231
:Ah, so nice.
232
:Well, and I can't eat gluten
anymore because of the bread here,
233
:but I can eat properly fermented
sourdough, which is not easy to find.
234
:But when I find it, I love it
because I can actually eat that.
235
:But if it's not properly
fermented sourdough.
236
:Um, and there's a lot of
pretend sourdough out there.
237
:They put vinegar in it or
something to make it taste sour,
238
:but it's not actually sourdough.
239
:Then I'm sick.
240
:I like the old tile stoves.
241
:You can see them in Europe in castles and
big buildings, but they used to be in all
242
:the apartments and they would be about
two meters high, six, seven feet high.
243
:And very massive, it's a massive
structure, um, brick structure
244
:with tiles on the outside.
245
:And so you make a fire and it heats up.
246
:And so this whole mass holds
the heater and you don't have
247
:to feed it and heat it up.
248
:And then at night, and it keeps the
house really warm, the apartment.
249
:I like that.
250
:You can, in old buildings in the
countryside, they made beds on top of it
251
:so people even could sleep on top of it.
252
:The tile stuff were amazing.
253
:That's cool.
254
:We discussed coffee, we discussed
flow, and so I would like to
255
:shed a light on a solar bakery.
256
:A bakery that bakes bread, makes
bread only with solar energy.
257
:And this is a bakery that
is located in Normandy.
258
:So on the West Coast in France, not
the sunniest part of France, but
259
:you'll be surprised because we don't
need so much sun to bake bread.
260
:The way it works is that you
have this, a big, big, big, what
261
:they call a solar concentrator.
262
:The job of this device.
263
:Is to collect the sun and
then reflect it into an oven.
264
:So the way this thing is made is that it's
a big panel of, um, not so big actually.
265
:It's, um, uh, the, the size of it is 11
meters square and it has 69 small mirrors.
266
:And that all collects the energy from
the sun and reflected into an oven.
267
:And it takes one hour to heat the oven.
268
:And when the sun is very, very strong.
269
:The temperature goes up to 900 degrees,
but you don't need 900 degrees to bake.
270
:Wow.
271
:Yeah.
272
:Yeah.
273
:I mean, you, you don't need 900
degrees, but when the sun is very
274
:bright, it can go up to 900 degrees.
275
:So in the video that I've seen that.
276
:On the day, like, you know, on a
day with some clouds, there's still
277
:sun, they can make up to four hours
of use of the, um, of the oven.
278
:And, uh, one hour of the use of oven
is you can make 40 kilos of bread.
279
:So, on a not so sunny day, like on
a cloudy day, you can make about,
280
:you know, 120, 160 kilos of bread.
281
:That is bread.
282
:And just imagine, uh, in the
summer, you know, how much bread
283
:you can make just with solar energy.
284
:And this business is inspired by solar
bakeries in Kenya and in Tanzania.
285
:It's something that they use over there.
286
:And so I think this is, uh,
this is really, really cool.
287
:But there's more, because sometimes they
don't have enough sun, um, because there's
288
:some days that there's just, you know,
it, it rains because it's in Normandy.
289
:So the weather is not always sunny.
290
:But what they do is because they want
to be energy frugal, if there's such a
291
:word, , when there's not enough sun for
the solar oven, what they do is they use
292
:this wood fire oven to, to bake bread.
293
:So that way they can provide
bread to their customers.
294
:And because they have this idea of
being very, uh, frugal with energy,
295
:um, everything they do is, I mean, when
they can do it, they do it manually.
296
:Like when you make bread,
you have to, um, knead it.
297
:You know, you need it when you need it.
298
:And so they do it by hand.
299
:There's no fridge and because
it's a business, so they do all
300
:the delivery on the bike, e bike.
301
:So I think this is, um, this is great.
302
:, and , this bakery, this is the
first bakery in France, but they
303
:want to transform the sector.
304
:What they want to do is
to make things better.
305
:And so they provide training.
306
:And as of.
307
:This year in, I think it was in
April, they have converted 10 bakeries
308
:in France to use the solar oven.
309
:Wow.
310
:That's fantastic.
311
:That really is.
312
:That really is.
313
:I bet it tastes good too.
314
:Now I'm hungry.
315
:I'm sure it's good, yeah.
316
:Yeah, but I'm actually doing more than
just making bread because they also
317
:use, when there's a lot of sun, they
also use the energy , from the sun
318
:and the heat from the oven to roast
beans because they were trying , to
319
:offer an alternative sources of beans.
320
:To peanuts, spices,
chocolate, and coffees.
321
:So they use the, the heat when
they have baked too many breads.
322
:And when the oven is still hot,
they use it to roast beans.
323
:So they're not wasting the
heat at all, which is great.
324
:No.
325
:Yeah.
326
:And, um, yeah.
327
:And so they're trying to promote other
like spices or way of making beverages.
328
:Very cool.
329
:Yeah.
330
:People are smart.
331
:They figure out things.
332
:Well, and I wonder too, if there's
trends, like there's, you know, trends
333
:with ideas and ways of doing things that
come in and out of fashion too, you know?
334
:Yes.
335
:Because last week you talk
about cardboard cameras.
336
:Yeah.
337
:Paper cameras.
338
:Yeah.
339
:Paper cameras.
340
:They're very, they're very trendy.
341
:Um, yeah.
342
:Yeah.
343
:Um, another thing that's trendy.
344
:Lately, that makes a lot of sense,
saves a lot of money, saves a lot
345
:of, um, everything, is a new thing.
346
:Well, it's a new thing.
347
:It's a new thing now.
348
:It's called baby lead weaning.
349
:Have you heard of it?
350
:And so it's not using
baby food in jars anymore.
351
:I used to make my baby food,
but now a lot of parents are not
352
:even giving their kids baby food.
353
:They're giving them regular food,
just in little pieces, and there's
354
:a whole way of thinking that.
355
:Children need to learn how to chew and
swallow and not choke, and that they can
356
:do it from a really, really young age.
357
:Part of what they need is a foot panel
on the high chair, because if you
358
:choke, your natural thing is to push.
359
:And so they want to make sure there's a
place to put their feet so they can push.
360
:And then the parents take first
aid so they know, you know, what
361
:to do if a child starts choking.
362
:Think of very tiny babies.
363
:are going now straight from breast milk
or a formula to actually eating real food.
364
:And there's no more of this feeding
with the baby food jars of food.
365
:And I thought, wow, this is old
again, going back to how it used
366
:to be, but it eliminates that whole
section of time where you need to
367
:buy jarred processed pre manufactured
baby food that has to, you know, be
368
:shipped on trucks and all this stuff.
369
:And I thought, wow, that like.
370
:Everything old is new again.
371
:And it's so healthy for kids to touch
it with their hands because that
372
:way they get all the information
from the reflexes and putting in
373
:their mouths instead of being fed.
374
:That's brilliant.
375
:Yeah.
376
:Yeah.
377
:They call it baby led weaning and
it's little pieces of things and
378
:there's particular things that they
recommend not doing until they're.
379
:You know, a bit older, but I
watched it happen and thought,
380
:wow, we never did this.
381
:We had jars of baby food or
we made our own baby food.
382
:That's great.
383
:So much smarter.
384
:That's so great.
385
:Yeah.
386
:I, I'm, I'm curious, Jen and Christina,
when you started this conversation,
387
:you say that there's something that
is big and something that is smaller.
388
:What is the big thing?
389
:What is a small thing?
390
:Oh, for me, the big thing was
the big ships and a big, big
391
:companies and an entire industry.
392
:And.
393
:The little thing for me, because
that's a big global thing and,
394
:and a manufacturing thing.
395
:And it's, it's a big, big, big, big thing.
396
:And the small thing was the sending
of letters and we can all do that.
397
:We can all, you could write your own
stories and send them or send postcards
398
:like you do Leakey and just do something
that's delightful and low tech because.
399
:Children don't necessarily need
everything to be computerized
400
:or done for them, right?
401
:To be able to have something in
your hand that you can hold, that
402
:you can look forward to getting.
403
:That you can read yourself or with
help and that's, you know, there's so
404
:much room for delight and imagination
in something so simple and so small.
405
:So that's what I was thinking.
406
:Yeah.
407
:But that's precisely why I think
that the, this letter thing is the
408
:much bigger thing than this ship with
boat, because you don't need to wait,
409
:you can do it right away and anybody
can do it and you can do it with.
410
:The new generation, you know,
the generation of the future.
411
:So that's, that's very,
very, very big to me.
412
:Well played.
413
:Well played.
414
:Okay.
415
:That was fun.
416
:That was wonderful.
417
:That was fun.
418
:Now we're all going to run out and
write letters and go eat bread.
419
:Get the yeast going, the farther going.
420
:That's right.
421
:Yeah.
