0:00
well if you're living in cold regions of
0:01
the world you would understand how
0:03
difficult and annoying it is to commute
0:05
with snow everywhere from roads and
0:07
sidewalks to stairs to commute with snow
0:10
everywhere from roads and sidewalks to
0:12
stairs so so to ensure safe transport of
0:15
goods and people Japanese authorities
0:17
have come up with a unique and
0:18
jaw-dropping solution they're like
0:21
develop a strange uh pretty strange in
0:23
fact sort of technology that can
0:25
instantly quite instantly melt snow on
0:27
roadways with pretty much less energy
0:29
and cost I mean a fraction of the actual
0:32
cost you'd see that it's one of the most
0:34
most efficient and effective way to get
0:36
rid of the Annoying snow from the
0:38
walkways and roadways you catch my drift
0:40
an effective way to get rid of the
0:41
Annoying snow from the walkways and
0:43
roadways you catch my drift well Japan
0:45
is a country with a lot lots of snowfall
0:47
in Winter an effective way to get rid of
0:49
the Annoying snow from the walkways and
0:51
roadways you catch my drift well Japan
0:54
is a country with a lot lots of snowfall
0:56
in winter so basically in high snowfall
0:59
in in winter areas like Hokkaido the Sea
1:02
of Japan coast of honu and mountainous
1:04
areas are all jam-packed with snow as a
1:06
matter of fact they spend enormous
1:08
enormous amount of money to clear the
1:10
snow and let people use roads or
1:12
walkways to that it's obvious that these
1:14
municipalities spend thousands of
1:16
dollars in an effort to clear off the
1:18
roads so basically they were used to
1:20
generate heat using electricity oil gas
1:23
as a fuel to form heaters or warm coils
1:25
under roadways to melt to that it's
1:27
obvious that these municipalities spend
1:29
thousands of dollars in an effort to
1:31
clear off the roads however this method
1:33
is costly and has a huge environment
1:36
impact so what's the solution before I
1:38
told you the solution why not spare a
1:40
minute to hit the like button because
1:42
the solution is just amazingly crazy
1:44
yeah Japanese authorities are finding a
1:47
way to deuse heat from the city's sewage
1:50
flowing through the sewer pipe in a way
1:52
to melt snow on roadways yes you're
1:55
hearing it right sewage has got a heat
1:58
pretty obviously but they've developed a
1:59
method to use that heat in their favor
2:02
and melt that pretty annoying snow with
2:04
less lesser energy and cost doesn't it
2:07
sound amazing well obviously I'm not
2:09
joking I'll share you some true facts
2:11
and the research that's underway so a
2:14
collaborative research body comprising
2:16
suisui Chemical Company Limited Kawa
2:19
Company Limited and Nagata City in
2:21
Nagata prefecture commissioned by the
2:23
National Institute for land and
2:25
infrastructure management of the
2:26
ministry of land infrastructure
2:28
transport and tourism has been working
2:30
to demonstrate a snow melting technology
2:33
for roadways using the heat from sewage
2:36
flowing through sewer pipes yes the
2:38
sewage heat to your rescue you already
2:41
know that the temperature of sewage
2:42
flowing through sewer pipes fluctuates
2:45
with the seasons just like like the
2:46
outside temperature but as a matter of
2:48
fact so that's where we can tap this
2:50
special characteristic of sewage
2:51
temperature to to use the heat from the
2:53
sewage is energy matsura tatsuro is a
2:55
senior researcher at the Wastewater
2:57
system division of the NM and he was of
2:59
The View view that sewage such as waste
3:01
water emitted from homes and factories
3:03
is available in stable and large
3:05
quantities especially in urban areas a
3:08
snow melting system for roadways was
3:10
developed as a way to use the heat from
3:11
the sewage effectively doesn't it sound
3:14
amazing well let's delve into the
3:16
working principle to see how it works as
3:18
a technology the sewage heat snow
3:21
melting system works by passing a pipe
3:23
called a heat collecting pipe through
3:26
the sewer with the circulating liquid
3:28
anti-freeze inside this pipe then heated
3:30
by the sewer heat and conducted to a
3:32
heat radiation panel installed under the
3:35
surface of the roadway heating the road
3:37
surface and melting the snow the key
3:40
aspect of this technological development
3:42
is that improvements in materials and
3:44
techniques have made it possible to melt
3:46
snow on roadways using less energy and
3:49
at lower cost than the conventional snow
3:52
melting systems that use heaters or
3:54
boilers employed to date that sounds
3:56
something out of this planet a genius
3:58
idea a material with high heat
4:00
conduction performance was used for the
4:02
heat collecting pipes the pump for the
4:04
circulating liquid was also made more
4:06
compact to achieve operating cost
4:07
savings and cut power consumption by
4:10
making adjustments to the types and
4:12
mixture of sand and stone for the paving
4:14
material on the surface of the roadways
4:15
where the heat panels are installed the
4:17
thermal conductivity can be
4:20
synergistically increased a
4:21
demonstration test conducted on a 200 S
4:24
met section of Road in nikata City
4:26
Center showed that this new system
4:29
reduces energy consumption by more than
4:32
90% compared to the conventional snow
4:34
melting systems employing heaters or
4:36
boilers that are mainly used now in
4:39
terms of total annual cost the new
4:42
system achieves an approximately 14%
4:44
reduction compared to the heater method
4:47
and approximately 5% compared to the
4:50
boiler method so that's all about our
4:52
today's episode of technology and
4:54
Innovation if you've loved this Japanese
4:57
Innovation hit the like button and let's
4:59
make this planet green and sustainable
