Saving Energy with the Zojirushi Electric Water Kettle

I have long been the very satisfied owner of a Zojirushi electric water kettle, officially known as the Zojirushi CD-LCC30 Micom 3.0-Liter Electric Dispensing Pot. As I originally wrote in my Amazon.com product review:
I purchased the Zojirushi 3 liter dispensing pot, and it runs 24 hours a day, 7 days a week in my house. We drink tea constantly, and it is wonderful not to have to wait to boil water. The Zojirushi allows you to set the desired water temperature based on your needs (i.e. 175 for green/white teas, 195 for other teas, 205 for cooking). The unit is tall enough to fit even our tallest to-go cup under the dispensing spout.
ZojirushiElectricKettle-300.jpgSince we've had the kettle, I wondered about the energy efficiency of it, since the outside of the unit can be fairly warm, suggesting that it isn't very well insulated. I also happen to have a Brand electric meter, an expensive and highly accurate meter used for measuring electric consumption. So I plugged the Zojirushi kettle into the meter, and let it run.

Measured over the course of three days, at about 70-72 degrees F ambient temperature, and with a water temperature setting of 195, the kettle used 0.9kwh/day! That's quite a bit just to have hot water. An average house might use about 30kwh/day, so 0.9kwh represents 3% of the entire energy budget. A very efficient house might use 15kwh/day, in which case 0.9kwh represents 6% of the energy budget.

I have previously read the typical home water heater wastes about 30% of energy consumed keeping the water hot. This ratio appears to be much higher for the Zojirushi. As measured by the Brand meter, initially heating the 3 liters of water takes ~0.25kwh. Maintaining that temperature over the next 24 hours then takes about 0.65kwh. (These numbers are somewhat approximate, since I didn't rigorously control for usage of the water kettle during testing, and assume that the entire 3 liter capacity is used every day, which is close to our actual usage.) This suggests that almost 70% of the energy consumed is wasted keeping the water hot, as opposed to the 30% of the energy used that is necessary for actually heating the water that we will consume.

ZojirushiInsulated-300.jpgI happen to have some foil insulation bubble wrap laying around. This inexpensive insulation product is often used to insulate crawlspaces. It has a pretty low R value, but is compact and flexible. I cut a piece to cover the water kettle, leaving room to dispense water, see the water level indicator, and creating a flap to allow access to the lid for adding water. Ideally the insulation would have been tight to the body of kettle, with as little room for airflow as possible to give the best possible performance. But in practice, using rubber bands and paper clips, there were still some big gaps.

I put the insulation on and checked back a couple of hours later. I noticed right away that the outside of the foil insulation was cool. And the space in between the foil insulation and the plastic housing of the kettle was quite hot: so indeed the insulation was working.

After three days, I checked the power consumption and found that with the extra insulation, the consumption was down to 0.75kwh/day. This is a 17% decrease in total power consumption compared to the unaltered kettle. And if you exclude the energy required for initial heating of the water, this is a 23% reduction in the energy that is wasted in maintaining the temperature. So a few cents invested in foil insulation wrap fastened with two rubbers saved 17% in total power consumption, and 23% in wasted power consumption. I could easily imagine the same product manufactured with more insulation (properly applied and in strategic locations like the top) could achieve power savings of 50%.

So we've decided to put our Zojirushi away for now, and have gone back to boiling water on the stove. It's not as convenient, but it is an easy way to save energy. Another alternative would be to buy a large capacity insulated thermos, boil water once per day, and store it in the thermos.

I'd really like to see Zojirushi develop a highly energy efficient version of their electric water kettle that has extra insulation.

Free and Simple - Reducing overhead and complexity

Commoncraft blog has a nice post on making the simple choices that reduce administration overhead and complexity:

The Beachcomber Cafe has made choices in how the business is run.  Sure, they have the potential to try to squeeze every dollar out of people who need wifi, but they don't.  They provide wifi as a worry-free service and rely on the good nature of people to support the business in other ways. 

Further, they put a priority on the lightweight choice - the wifi is always on, always free and open to everyone.  Any other way would create more hassle than she needs. The store hours are even easy to remember. 

I'm not talking about business practices, but philosophy - a philosophy that's built on shedding unneeded administration and focusing on providing opportunities that give people ways to feel good about the relationship.

The first step is realizing you have a choice.  Your business doesn't have to operate like others.  Sure, you can make 8 dollars a day on wifi, or you can smile at your customers and tell them the wifi is free and goes great with today's paper and a candy bar. 

 I think kind of simplicity as a philosophy is exactly what makes free business models possible, and is a driving force behind much of the web 2.0 innovation.

Kings lomatia - the 43,000 year old shrubbery

The story of the 43,000 year old, self-cloning, sterile , triploid Audstralian shrubbery:

Why is it endangered? L. tasmanica is endangered because it only occurs naturally in one small area in the world. The total wild plant population is around 500 individuals all restricted to one disease and fire prone area. Kings lomatia (Lomatia tasmanica) occurs as a single population in Tasmania's remote southwest within the Wilderness World Heritage Area.

It is a Tasmanian endemic, first recorded by miner and naturalist, Deny King in 1937 at New Harbour but this population seems to have since disappeared. During the 1960's Deny sent specimens of the plant to the Tasmanian Herbarium to be identified and so it became known to science. Its common name "Kings lomatia" is in honour of the man who discovered it.

Why are these plants unable to sexually reproduce? Although this plant does produce flowers it has never produced fruit or seed. The reason for this is that the plant is a triploid. This means it has three sets of chromosomes instead of the normal two. This renders the plant sterile. Other Tasmanian species, L. tinctoria and L. polymorpha are diploid (two sets of chromosomes), as are other species of the genus and the subfamily to which it belongs.

The only way it can reproduce itself is by vegetative means. It simply clones itself. When it gets old and falls down, it puts out new suckers and grows up again. It is still theoretically the same plant.

In fact latest research has shown that Kings lomatia is all one single clone. There is no genetic diversity within the population. This means that all the individual Kings lomatia plants are genetically identical.

The oldest plant clone in the world! Amazingly, this plant clone has been around for at least 43,600 years. At Melaleuca Inlet some Pleistocene fossils of Lomatia leaves were found that appear to be L. tasmanica. Radio-carbon dating gave a minimum age of 43,600 years for the layer in which the leaf fossil was found.

Happy Earth Day: Canada Declares BPA Toxic

As reported by the New York Times, Canada officially declared bisphenol-a (BPA) toxic, leading the way to ban polycarbonate baby bottles:
The Canadian government moved Friday to ban polycarbonate infant bottles, the most popular variety on the market, after it officially declared one of their chemical ingredients toxic. The action, by the departments of health and environment, is the first taken by any government against bisphenol-a, or BPA, a widely used chemical that mimics a human hormone. It has induced long-term changes in animals exposed to it through tests.

Greenland lake disappears under the ice

This report via Ars Technica about glacial lake draining is amazing:
A report in today's Science describes how researchers recorded the drainage of one such lake in Greenland. The lake was roughly 5.6 km2, but drained completely in less than an hour and a half. The lake's contents rapidly made their way down to the bottom of the ice sheet, 980 m below the surface. During this period, the average drainage rate was 8700 m3/s. For reference, the average flow rate for Niagara Falls is only 5700 m3/s.

Why I Let My 9-Year-Old Ride the Subway Alone « FreeRangeKids

Free Range Kids is a great site about restoring freedom and independence to kids so that they can develop skills and confidence. A recent post about letting her 9 year old ride the subway alone starts:
I left my 9-year-old at Bloomingdale's (the original one) a couple weeks ago. Last seen, he was in first floor handbags as I sashayed out the door. Was I worried? Yes, a tinge. But it didn't strike me as that daring, either. Isn't New York as safe now as it was in 1963? It's not like we're living in downtown Baghdad.

Anyway, for weeks my boy had been begging for me to please leave him somewhere, anywhere, and let him try to figure out how to get home on his own. So on that sunny Sunday I gave him a subway map, a MetroCard, a $20 bill, and several quarters, just in case he had to make a call.
Growing up in Brooklyn, NY, I fondly remember wandering a distance of several miles at around the same age with my cousin Douglas.

12 tips for eating right inexpensively

Robyn has 12 tips for eating right inexpensively that are especially handy for those that may want to eat organic but need to keep food costs down. Here's a couple of examples from her blog:
  1. Quit buying vitamin supplements (see my Nutrition Manifesto Myth #4) and apply that cost savings to whole plant foods.
  2. Quit buying chips, soda, and packaged cookies and candy. Quit buying meat. Quit buying fast food. These things are costing you more than you may realize.
  3. Instead, buy grains and legumes, which are higher in protein than people expect, inexpensive, and they keep in storage for years. Try serving grains/legumes most nights a week instead of meat.
