“Growing
electricity demand for air conditioning is one of the most critical blind spots
in today’s energy debate. With rising incomes, air conditioner ownership will
skyrocket, especially in the emerging world. While this will bring extra
comfort and improve daily lives, it is essential that efficiency performance
for ACs be prioritized. Standards for the bulk of these new ACs are much lower
than where they should be.”
Director of the IEA.,
Dr Fatih Birol, the Executive, commenting on their report The Future of cooling
- Opportunities for energy-efficient air conditioning
The
Earth is getting hotter due to Global Warming. So the demand for cooling is
going to skyrocket.
In
practical terms, that 5.6 billion air conditioners translates to 10 new ACs
sold every second for the next 30 years, as pointed out in their IEA YouTube
video.
So
what implications does this have for our modern way of life?
The Future of cooling -
IEA AC prediction tempered by the rise in Solar PV Power
On
way to look at this is in terms of the demand for energy these power hungry
devices will bring.
The
current stock of air conditioners and electric fans use 10% of all global
electricity consumption today. As more Jamaicans and other people living in
countries lost to the Equator and in the Temperate zones “step up inna life”,
they'll begin to spend more on air conditioners and fans.
AC
use is expected to be the second-largest source of global electricity demand
growth. It'll trail the industry sector, and the strongest driver for buildings
by 2050.
In
fact, they predict that global renewable electricity capacity to rise by more
than 920 gigawatts, or 44%, by 2022. So with enough power to supply all global
demand coming from Renewable resources, why the need for conservation?
Global Warming and AC -
Photovotaics cannot handle increase in AC Power Demand
Supplying
power to these ACs comes with large costs and environmental implications. The
report identifies key policy actions.
In
an Efficient Cooling Scenario, which is compatible with the goals of the Paris
Agreement, the IEA finds that through stringent minimum energy performance
standards and other measures such as labelling, the average energy efficiency
of the stock of ACs worldwide could more than double between now and 2050.
This
would greatly reduce the need to build new electricity infrastructure to meet
rising demand.
Making
cooling more efficient would have multiple benefits such as:
1.Making
energy more affordable
2.Making
Energy more secure
3.Making
Energy more sustainable
4.Saving
US$2.9 trillion in investment, fuel and operating costs
The
stats are also against increasing energy capacity just to meeting cooling:
1.90%
of households have air conditioning in the United States and Japan
2.8%
of the 2.8 billion people living in the hottest parts of the world have air
conditioning
That
is less than 30% of hired of global households owning an air conditioner. Such
a sharp increase among households in AC usage could see electricity loads on power
grids spike as much as 45% in 2050.
ACs sold in Japan and the European Union are
typically 25% more efficient than those sold in the United States and China.
Efficiency improvements could reduce this future energy monster.
Samsung’s
AC's use R32, an environmentally-friendly refrigerant alternative, to keep in
line with the strengthened environmental regulations in Europe! When compared
with the standard R410A refrigerant, R32 has only one-third of its global
warming potential (GWP) and is characterized by its high-efficiency even in
lower quantities.
So
what if all AC’s became energy Efficient? Would that stem the rising demand in
AC?
Mandatory Energy
Efficient AC Standards - The Quest for Solar Powered Air Conditioners
Short
answer is no, as the IEA is wrong. The demand for electricity is going to grow
faster than expected, as Fans may be the go-to device for cooling rather than
AC.
Instead
I predict the rise in AC usage will be in motor vehicles. Motor vehicle AC,
which are not included in this report, will have an impact on motor vehicle
fuel economy. This translates to increased demand in electricity, as electric
generation will have to increase when Electric Vehicle becomes more mainstream.
One
simple way to make Air conditioners more efficient, be they for households or
for motor vehicles, is to simply not connect them to the grid.
This
so that the device doesn't have to be tied to grid power – and yes, it is
possible to power AC's using Solar Power as this video indicates.
Director
of the IEA., Dr Fatih Birol, points out that by making AC more efficient, we
reduce the need for new sources of power to fuel our cooling passion, quote:
“Setting higher efficiency standards for cooling is one of the easiest steps
governments can take to reduce the need for new power plants, and allow them at
the same time to cut emissions and reduce costs”.
This
will leave more of that new Renewable Energy capacity to fuel Electric Vehicles
and do other things besides keeping our houses and cars cool.

“This
is only one solution of many and at the end when we review this pilot project
we will be in a position to see if it’s worth taking it islandwide.
Prime Minister of
Jamaica, Andrew Holness at the launch of PCJ's Solar Lamp project
The
Home Sweet home lamp may soon be on exhibit in a museum for your future
children to be reminded of the good...and bad days.
This
as the PCJ (Petroleum Corporation of Jamaica) has launched a pilot project to
provide 5,000 Solar Lamps to residents in inner-city communities across St
Andrew as noted in the article “Gov't
Launches Solar Lamp Pilot Project”, published Monday April 30, 2018 by Paul
Clarke, The Jamaica Gleaner.
The
aim of the project is to reduce house fires caused by people living in the
inner city using candles and lamps. Often when these are lit, they are left
with children unattended. The children play and turn over these candles and
kerosene lamps, setting their bed linen, curtains and then the whole house on
fire.
The
blaze quickly razes many of their dwelling, which may be nothing more than a
wooden shack with a zinc roof.This is
something that the Prime Minister of Jamaica, Andrew Holness deals with in his
constituency, quote: “Almost every year, as a representative, I have had to
deal with burnouts; someone’s home will be destroyed by fire. It’s not arson;
it’s that we have an aging housing stock that is made primarily of wood. Some
people also make their houses out of cardboards and baggas”.
The
Solar Lamp Project, which is expected to address and prevent this problem, is
been overseen by the PCJ, as pointed out by the Prime Minister of Jamaica,
Andrew Holness: “With simple and inexpensive actions, the Government can make a
difference in the lives of energy-poor households, and particularly and
significantly reduce or virtually eliminate the risk of these tragic fires”.
PCJ's Solar Lamp
Project – Solar will save inner-city kids home alone
According
to the PCJ Chairman, Russell Hadeed, this fits their long term plan to:
1.Promote
energy efficiency
2.Fix
the problem of house fires
The
Solar Lamps have a lifespan of 2 years and require eight (8) hours in the sun
to be fully charged. After that, they can provide up to 20 hours of light on
the low beam feature and roughly six hours when used on the high beam feature.
This
is more than enough to last the night and is actually a lot better than my lap,
as shown below, which requires 2 hours to fully charge but lasts only 6 hours
on the low beam feature and to 8 hours on high beam setting.
Still,
parents cannot get away from their responsibility, as this really eliminates
the risk factor associated with open flames and lamps, to quote the Prime
Minister of Jamaica, Andrew Holness: “While this programme will remove one of
the risk factors in such fires, ultimately, however, parents and guardians are
responsible for the safety, care and protection of their children. We must
educate, support and empower our parents, so that those who want to do better
will, while ensuring that the organs of State are in a position to protect
children from those parents who refuse”.
Eliminating
the open flame will save inner-city kids home alone. Hopefully, too, this may
expand to solar power being used to power entire homes, lighting and all.
“WebAuthn
is a set of anti-phishing rules that uses a sophisticated level of
authenticators and cryptography to protect user accounts. It supports various authenticators,
such as physical security keys today, and in the future mobile phones, or
biometric mechanisms such as face recognition or fingerprints.”
Mozilla explains
Firefox “Quantum,” version 60.0 support for Web Authentication standard and
USB-based security keys
Finally,
a browser is jump-starting the password-free logins concept on the Internet!!
USB-based
security keys such as Yubico’s YubiKey ar a part of that mix. Yubico offers standard YubiKeys USB-A
and USB-C models that remain plugged into your PC (full-size or nano). Their
“Neo” models are key-chain danglers that use USB-A and NFC connectivity for PCs
and Android phones. Their “FIPS” models are for government and regulated
industries, so options abound for every type of customer.
Now
with Firefox support, a web-based account using a one-time registration token
enables your YubiKey USB Key, eliminating the need to enter a password as long
as it's plugged in.With support for
face recognition and fingerprint scanning in the pipeline, you may only need to
have clean digits or look you best to access you computer!!!
Yubico
are physical USB keys that replace typing in passwords. So how does Web
Authentication work, exactly?
WebAuthn - E2EE
encryption between a Browser to a Server
The
alternative, WebAuthn (Web Authentication), is equally interesting.
WebAuthn
uses encrypted public and private keys; there are no passwords stored in a
website’s database. Even more interesting there are no passwords for hackers to
scoop on a compromised website. This is because no data is transmitted from
your PC to the website.
WebAuthn
stores your login and password credential in an encrypted form and await
instructions from the user, also encrypted, to access a password protected
website. This way no password data is being passed from data passed from your
PC to the website; only instructions to the server to authenticate you on the
website you are logging into using encrypted public and private keys.
Effectively,
this is E2EE encryption between a Browser to a Server and then to the website
you are logging into.
WebAuthn
goal is to authenticate account owners using biometrics i.e. face or
fingerprint. This is harder to hack than letters, numbers and characters
hackers could eventually discover. This may mean you will have to soon invest
in a fingerprint scanner and a web camera. But if web security is important to
you, then this should not be a problem.
So
when do you start using this? And what about Google Chrome and Microsoft Edge
Browsers?
Google Chrome and
Microsoft Edge Browsers - Break from centuries old passwords
WebAuthn
is in its early rollout stages and currently only supports desktop web
browsers.
Eventually
WebAuthn will support smartphones, giving a boost and possibly replacing
Two-step authentication long used by developers and companies. Chrome 67 will
reportedly offer support later this month, followed by Microsoft Edge, so if
you’re a fan of those browsers, you don't have long to wait!!!
The
latest Firefox release provides other noteworthy features as well:
1.A
wider layout on new tabs
2.A
larger Top Sites menu sporting eight icons
3.Larger
Highlights icons.
4.The
Pocket’s recommendation section now displays an occasional sponsored story as
well
Enterprise
customer planning on deploying Mozilla 60 can now enjoy:
1.IT
to customize the browser for the office
2.Rapid
Release build that auto-updates roughly every six weeks
3.Extended
Support Release that updates once per year
Customization
can be performed using the Group Policy tool on Windows, or through a JSON file
supporting Mac, Linux, and Windows.
Still,
the Web Authentication standard and USB-based security keys is a Quantum leap
forward and represent the future where E2EE and authentication using biometrics
replaces centuries old passwords!!!
Unfortunately,
the procedure I listed in the blog article isn't working 100%.
So
I've begun looking for an alternative way to reset the Ink Level Monitoring in
these refilled cartridges......and I think I may have found just the thing!!
How to reset a printer
cartridge using a Print cartridge chip resetter
Canon
inkjet printers use ink cartridges that are equipped with an Ink Level
Monitoring. This is a microprocessor that reports when a cartridge is low or
out of ink.
The
actual process of resetting a printer ink cartridge cannot be done via the
printer, as I’ve discovered from doing some detailed research into Canon
Ink Cartridge Resetting. Rather, you have to reset the printer cartridge
using a Print cartridge chip resetter designed for your specific cartridge
model.
Print
cartridge chip resetters may be purchased as a standalone product or may be
included with refill kits. A simple search on eBay for “Print cartridge chip resetter Canon pixma mg2522”, yielded the
following results.
Hopefully
when the device arrives, it'll help me reset my refilled printer cartridge for
my Canon Pixma MG2522 Printer and allow me to continue printing.
You
can modify the search term to search for Print cartridge chip resetters for
other models of printers, as these chip resetters are specific to each model
and type of cartridge.
Sharing
is caring so share this bit of info with someone who is in a jam and need their
printer printing again!!!
“It
is about safety. Sometimes people come out of an agent location with a bundle
of cash and we don’t want that”
President of Alliance
Group of Companies, Peter Chin, at the launch of the card at the Marriott
Courtyard Hotel in Kingston on Thursday May 4 2018
Jamaica,
get ready for an alternative to Debit Cards that your children can use!
It's
called an Alliance Prepaid MasterCard, which is basically a Prepaid Card and it’s
being launched by Alliance Payment Services Limited as reported in the article “Alliance
Launches First Non-Bank Card”, published Thursday
May 3, 2018 by Steven Jackson, The
Jamaica Gleaner.
The
launch event took place at the Marriott Courtyard Hotel in Kingston on Thursday
May 5th 2018. MasterCard was represented at the event by Uhreil Bedoya, the
country manager for Jamaica, Trinidad & Tobago, Bermuda and Haiti.
With
this launch, Alliance Payment Services Limited becomes the first non-bank
operation in Jamaican to launch a prepaid card. Good to note that Alliance
Payment is an associated company of Alliance Financial Services Limited.
They
are an agent of MoneyGram with some over 50 sub-agents nationwide, making this
a product aimed squarely at the unbanked in Jamaica who receive their money via
remittances.
This
may also be their response to GraceKennedy and Western Union's plans to launch
their online website and app. This App, possibly using tech tools from
cryptocurrency Ripple, will allow customer to both send and receive remittances
directly to their Bank accounts as noted in my Geezam
blog article entitled “How
Western Union and GraceKennedy may use Ripple in GK MPay App”.
So
when will the product officially go live? Will this product enable e-commerce?
Alliance Prepaid
MasterCard - Electronic Transactions for Children and potential e-commerce
Payment platform
Alliance
Prepaid MasterCard, which was two (2) years in the making, will be officially
available on Friday, May 11th 2018 at Alliance’s head office in New
Kingston or its agents islandwide. They’ve long had Prepaid Cards in the form of
Alliance Payment Services Limited’s ePay Card.
Not
only will customer be able to receive their remittance via the card and
withdraw via ATM, but relatives abroad will also be able to send money to the
card via an Android App.
Because
it can be topped up, this could be a convenient option for parents wanting to
give their under-aged children a limited amount of money to spend locally as
well as online!!! Getting the card is free, but there are usage fees that may
be a bit daunting:
1.JA$40
per withdrawal
2.JA$10
at point of sale outlets
Still,
Prepaid Cards will now be a part of the mix of options to get more of Jamaica's
unbanked to use more Electronic Transactions. This mix already includes
GraceKennedy GK MPay and Quisk, now that JCCUL 's Quisk is not out of the
picture as noted in my Geezam
blog
article entitled “JCCUL
Shutters CONEC Mobile Wallet, leaving Quisk and MPay in the Race”.
Eventually
more services will be coming to make Electronic Transactions available to all,
as pointed out by Minister of Finance, Dr Nigel Clarke, quote: “Of great
significance is the fact that the guidelines provide collaboration with
existing service providers to bring innovative payment solutions to the
market......The service providers are directly relevant to the daily business
of Jamaicans. Depending on the providers the services include bill payment,
person to person benefits, e-cards, point of sale machines, accounting
enquiries, remittance disbursement and others”.
I
am very interested to see if this Alliance Prepaid MasterCard can be integrated
into websites and used for e-commerce i.e. buying and selling items online. If
so, remittances may not be the only use that this card has and it popular will
skyrocket, as it would provide a practical way for Web entrepreneurs to set up
e-commerce websites.
