‘IT WAS AN ACCIDENT’: THE SCIENTISTS WHO HAVE TURNED HUMID AIR INTO RENEWABLE
POWER

Posted on July 2, 2023July 2, 2023 by Bill Christensen

Source and full article:
https://www.theguardian.com/science/2023/jul/02/it-was-an-accident-the-scientists-who-have-turned-humid-air-into-renewable-power

In May, a team at the University of Massachusetts (UMass) Amherst published a
paper declaring they had successfully generated a small but continuous electric
current from humidity in the air. It’s a claim that will probably raise a few
eyebrows, and when the team made the discovery that inspired this new research
in 2018, it did.

“To be frank, it was an accident,” says the study’s lead author, Prof Jun Yao.
“We were actually interested in making a simple sensor for humidity in the air.
But for whatever reason, the student who was working on that forgot to plug in
the power.”

The UMass Amherst team were surprised to find that the device, which comprised
an array of microscopic tubes, or nanowires, was producing an electrical signal
regardless.

Each nanowire was less than one-thousandth the diameter of a human hair, wide
enough that an airborne water molecule could enter, but so narrow it would bump
around inside the tube. Each bump, the team realised, lent the material a small
charge, and as the frequency of bumps increased, one end of the tube became
differently charged from the other.

“So it’s really like a battery,” says Yao. “You have a positive pull and a
negative pull, and when you connect them the charge is going to flow.”

For their recent study, Yao’s team have moved on from nanowires, and instead are
punching materials with millions of tiny holes, or nanopores. The device they
have come up with is the size of a thumbnail, one-fifth the width of a human
hair, and capable of generating roughly one microwatt – enough to light a single
pixel on a large LED screen.

So what would it take to power the rest of the screen, or indeed a whole house?
“The beauty is that the air is everywhere,” says Yao. “Even though a thin sheet
of the device gives out a very tiny amount of electricity or power, in
principle, we can stack multiple layers in vertical space to increase the
power.”

That’s exactly what another team, Prof Svitlana Lyubchyk and her twin sons,
Profs Andriy and Sergiy Lyubchyk, are trying to do. Svitlana Lyubchyk and Andriy
are part of the Lisbon-based Catcher project, whose aim is “changing atmospheric
humidity into renewable power”, and along with Sergiy they have
founded CascataChuva, a startup intended to commercialise the research. They
first began working on the idea in 2015, some time before Yao’s team at the
UMass Amherst. “We were considered the freaks,” says Andriy. “The guys who were
saying something completely impossible.”

In fact, trying to prove the worth of an early proof-of-concept at conferences
had them literally red in the face. He says: “The signal was not stable and it
was low. We were able to generate 300 milliwatts, but you had to put all your
effort into your lungs in order to breathe enough humidity into the samples.”

They’ve come a long way since then, with Catcher and related projects receiving
nearly €5.5m (£4.7m) in funding from the European Innovation Council. The result
is a thin grey disc measuring 4cm (1.5in) across. According to the Lyubchyks,
one of these devices can generate a relatively modest 1.5 volts and 10
milliamps. However, 20,000 of them stacked into a washing machine-sized cube,
they say, could generate 10 kilowatt hours of power a day – roughly the
consumption of an average UK household. Even more impressive: they plan to have
a prototype ready for demonstration in 2024.

SCIENTISTS SOLVED THE MYSTERY OF HOW THE MAYA MADE PLASTER SO STRONG

Posted on May 27, 2023May 27, 2023 by Bill Christensen

Examples of head-scratchingly impressive building material can be found
throughout the ancient world, and Maya lime plaster ranks high among them.

Scientists from the University of Granada in Spain explored why this plaster was
a step above the building materials of its mesoamerican peers.

The secret ingredient was sap from nearby trees, introduced during the
plaster-making process. The sap created insoluble crystalline structures
(similar to those found on the shells of mollusks) that were well-suited to
surviving the hot and humid climate of central America.

HEAT PUMPS ARE NOW MANDATORY IN NEW HOMES IN WASHINGTON STATE

Posted on December 12, 2022November 12, 2022 by Bill Christensen

Washington State will require new homes and apartments to have heat pumps
installed from July 2023, the State Building Code Council ruled on Friday.

In April, the Council passed a measure requiring that heat pumps be installed in
new commercial buildings and large apartment buildings.

This heat pump mandate now covers all residential dwellings, and that makes
Washington State a leader in having some of the most robust building codes in
the US to require electrical appliances and thus reduce emisisons.

In a May 2019 policy brief, Governor Jay Inslee (D-WA) wrote:

> While statewide emissions have grown 10% overall since 1990, building
> emissions have jumped by 50%, more than any other source in our state.

As of 2020, 56% of Washington residents used electricity for heating, and 37% of
residents used natural gas or bottled, tank, or LP gas.

The Biden administration’s Inflation Reduction Act provides $4.5 billion of
direct rebates for heat pumps for low and moderate income households under the
High Efficiency Electric Home Rebate Act (HEEHRA). A low-income household will
receive a rebate that covers the full cost of a heat pump installation for space
heating, up to $8,000.

And under the The Energy Efficient Home Improvement credit, “Households can
deduct 30% of the costs for buying and installing a heat pump water heater or
heat pump for their space heating and cooling, up to $2,000,” according
to Rewiring America.

An air-source electric heat pump uses refrigerant to pull heat from cold outdoor
air and transfers it indoors when it’s cold, and it pulls heat out of the warm
indoor air to cool your home when it’s hot outside.

New homes in Washington State are going to save money up front due to rebates
and tax credits and they will also save money in the long run, as heat pumps
reduce electricity consumption by up to 50%. Emissions will be cut as well.

FRANCE TO REQUIRE ALL LARGE PARKING LOTS TO BE COVERED BY SOLAR PANELS

Posted on November 12, 2022November 12, 2022 by Bill Christensen

In France, solar just got a huge boost from new legislation approved through the
Senate this week that will require all parking lots with spaces for at least 80
vehicles – both existing and new – to be covered by solar panels.

The new provisions are part of French president Emmanuel Macron’s large-scale
plan to heavily invest in renewables, which aims to multiply by 10 the amount of
solar energy produced in the country, and to double the power from land-based
wind farms. 

Starting July 1, 2023, smaller carparks that have between 80 and 400 spaces will
have five years to be in compliance with the new measures. Carparks with more
than 400 spaces have a shorter timeline: They will need to comply with the new
measures within three years of this date, and at least half of the surface area
of the parking lot will need to be covered in solar panels.

According to the government, this plan, which particularly targets large parking
areas around commercial centers and train stations, could generate up to 11
gigawatts, which is the equivalent of 10 nuclear reactors, powering millions of
homes. Public Sénat writes that stipulations were put into place excluding
parking lots for trucks carrying heavy goods or parking areas in historic or
protected areas, to avoid “distorting” them, according to an amendment to the
bill. While it’s unclear, future iterations of the bill will likely detail
parking lots that would be excluded, in addition to how this plan will be funded
and what the penalties would be for lack of compliance.

SMART THERMOSTAT SWARMS ARE STRAINING THE US GRID

Posted on July 17, 2022July 17, 2022 by Bill Christensen

Source: https://www.theregister.com/2022/07/13/smart_thermostat_strain

Smart thermostats, those unassuming low-power gadgets designed to keep homes at
comfortable temps, are having an impact far wider than most might have
considered, according to recent data.

A paper from Cornell University brings bad news for renewable energy enthusiasts
– smart thermostats are secretly taxing the grid.

Smart thermostats, which the paper said were present in around 40 percent of US
homes in 2021, are programmed by default to have different night and day modes.
In hundreds of thousands of homes across the US that means a sudden jump in
electricity use right before residents wake up – if people aren’t changing
default settings, which the paper suggests is the case. 

Those hundreds and thousands of smart thermostats, typically configured to
switch to day mode around 6am, “can cause load synchronization during recovery
from nightly setpoint setbacks, increasing the daily peak heating electrical
demand,” the paper said. 

Cornell professor Max Zhang and PhD candidate Zachary Lee, the paper’s authors,
wrote that most studies predicting electrical demand fail to account for smart
thermostats and the stress they can place on the grid.

“As we electrify the heating sector to decarbonize the grid, this so-called load
synchronization will become a problem in the near future,” Zhang said.

To address the problem, Zhang and Lee built a dataset from publicly available
smart thermostat logs collected by EcoBee that contained anonymized temperature,
set point, runtime, and home occupancy statistics.

They used the data to examine energy costs during a New York City winter, and
found that load synchronization often occurs before renewable resources, like
solar, have had a chance to kick in and take stress off the grid. That stress is
actually aggravating peak demand by 50 percent, the paper said.

Zhang and Lee also found that energy-saving mechanisms built into smart
thermostats are less effective than advertised, with most homeowners only seeing
energy savings of 5-8 percent, as opposed to the 25-30 percent they’re capable
of. 


THINKING OUTSIDE THE HOME

The world is electrifying at an ever-quickening pace, and environmental problems
have cropped up along the way. Electric cars create battery waste, as do other
electronics, and removing carbon emissions from homes doesn’t mean power plants
have dropped coal and gas in favor of sustainable solutions. 

Those solutions, like solar and wind, “require a considerable amount of real
estate, and the right weather, and as a result they’re typically located far
from the cities they would serve,” the Washington Post‘s Will Englund wrote. 

Smart thermostats increase frequency and magnitude of peak energy demand, and
without more tenable ways to store energy from renewables, Lee said, they could
offset greenhouse gas reductions from electrification.

Energy Fairness, a nonprofit allegedly funded by gas and oil interests, thinks
that the challenges of electrification require emphasizing energy
reliability above all else. Zhang and Lee’s paper, while not arguing for the
retention of fossil fuels to support grid reliability, does suggest that close
monitoring will be key.

“Future energy system planning must consider the interaction of weather,
generation capacity, and energy management tools, show a large performance gap
between potential energy savings and actual energy savings,” Zhang and Lee
wrote.

Zhang suggests there may be an easier way to ease grid stress from smart
thermostats: educate consumers on how to use them so default settings are
changed. Even that may have its limits of effectiveness, though.

“In the end… we have to make smart thermostats even smarter,” Zhang said.


SCIENTISTS CREATE 3D-PRINTED BUILDINGS FROM SOIL

Posted on March 4, 2021July 14, 2022 by Bill Christensen

Eco-friendly technology could potentially replace concrete and revolutionize
sector

Scientists have developed a method to 3D-print greener buildings using local
soil that they say has the potential to revolutionise the construction industry.

The technology is designed to be a sustainable alternative to concrete, which
accounts for approximately 7% of carbon dioxide emissions, according to the
International Energy Agency.

Sarbajit Banerjee, a professor of chemistry and materials science and
engineering at Texas A&M University, said 3D printing enabled a versatility that
allowed them to print entire architectural facades, although getting such
structures to meet existing building regulations remained a significant
challenge.

Concrete remains the primary material used in many construction projects but it
cannot be recycled and requires a lot of energy to mix and transport. The
research team’s aim is to print structures using the type of soil that can be
found in any garden.

“While the widespread use of concrete has democratised access to housing and
enabled the growth of cities, this has come at a considerable environmental
cost,” said Banerjee.

WHAT IS A COLLOQUIUM?

Posted on August 12, 2020October 2, 2020 by Bill Christensen

A small band of natural building enthusiasts and outlaws met in a field over 20
years ago at something they called a ‘colloquium’. The movement they created has
grown uncontrollably ever since; reviving and innovating ancient building
techniques and training thousands in the essential, empowering art of building.



Now, as the world faces resource scarcity, increasing climate refugees and 3
billion more people on the way, this tiny backwoods movement prepares for the
mainstream. Join these merry pioneers as they celebrate their successes; sharing
stories, techniques and wisdom as they brace to meet the needs of a world in
crisis.


THATCH-COVERED ENTERPRISE CENTRE MAY BE THE WORLD’S GREENEST BUILDING

Posted on March 20, 2016July 14, 2022 by Bill Christensen

Prefab thatch wall panels (built indoors during the off season) and materials
palette which the Treehugger writer calls ‘almost edible’.

“John French, CEO of the university’s Adapt Low Carbon Group and project
director, … was eager that the next generation of buildings at UEA should move
away from high thermal mass and a dependence on carbon-intensive concrete,
towards natural and locally sourced materials.”



“The building also features a wide array of other sustainable materials
including recycled timber finishes, wood wool acoustic boards, spray-on
cellulose, and wall coverings made from hemp, nettle fabric and reeds”

Posted on September 24, 2014February 25, 2020 by Bill Christensen

Ryan Chivers of Atesano Plaster recently started a new LinkedIn group for
Tadelakt Professionals.

This group is a forum for professional tadelakt applicators and those involved
in tadelakt material sales and formulation. Discussions will focus on technical
aspects of the craft as well as the business side of tadelakt installation.

Tadelakt, for those who are unaware, is a lime-based plastering technique which
produces a beautiful water resistant surface with a high polish.
