Ironically, while American politicians and even consumers are spending critical time and resources attempting to band-aid economic and climate issues surrounding oil energy with everything from carbon offset policies to back-to-the-woods survival techniques, our counterparts in other countries — including engineers, businesspeople, and energy providers — are tackling the problem the old fashioned way by redesigning technologies and at the same time inventing new ones.
Over the holiday weekend, as I was trying to figure out new ways to lower my fuel bills, I found this really amazing hot water boiler and electricity generator invented in New Zealand by a company called WhisperGen. As soon as I saw it, I was reminded of a television commercial from the early 1980s in which actor Lorne Green is drumming up the exciting features of a slick new sports car that had fuel efficiency of 70mpg. But instead of ending the commercial with a "Buy one now" call to action line, Mr. Battleship Galactica closed with this punch in the gut: "There's only one catch. You can't buy it."
So why is America so intent on not commercializing energy efficient products, anyway? Below the fold: Discover WhisperGen, but remember — you can't buy it. Not in Amerca.
The WhisperGen apparently seems like such a promising energy appliance that New Zealand's primary electrical utility, Meridian Energy Limited, bought controlling shares of the company. Interestingly, not only is Meridian the largest power provider in New Zealand, it also happens to be the only one in that country certified as carbon neutral by virtue of its 100% use of renewable energy resources. While the WhisperGen as a standalone is not carbon neutral, it produces 20% less carbon than standard oil-fired boilers and has an overall efficiency rating of 95%.
Whisper Gen makes only two products: a hot water and power generating appliance for residential use and another version of the same device for off-the-grid homes, boats, etc. The residential unit is close in size and appearance to a standard dishwasher and it operates a little more quietly. As a heating appliance, the WhisperGen is designed to replace an oil-fired boiler for both hot water and home heating purposes. The residential unit kicks out about 1.2 kW AC, is wired to the grid and is generally promoted as a supplemental source of electricy for residential use. The unit would therefore replace any emergency gas-fired generator reserved for occasional power outages.
The engineering that went into the design of this product may be considerable, but some of the underlying technology is actually old and relatively well known. Domestic hot water and room heating are achieved by way of a liquid propane or natural gas burner. No big deal, right? But in the WhisperGen, excess hot water is used run an internal power generator device known as a Stirling Engine, which was invented and patented by Robert Stirling in 1816. Both of these technologies have been around for quite a long time.
What makes the WhisperGen very interesting is the way company engineers were able to commercialize the Stirling Engine by converting the linear motion of the pistons housed in the Stirling Engine to a rotating motion needed to turn an alternator. They were able to do this with a microchip and a cast iron "wobble yoke" invented for this purpose. Significant new engineering introduced by the WhisperGen is in this globally patented wobble yoke and the algorithms stored in the Electronic Control Unit assuring smooth, low-vibration operation between the linear piston movement and rotating alternator drive. The invention of the wobble yoke alone is likely to serve a host of other industrial applications. In fact, according to an article in Eureka Magazine:
The curious thing about this unique design is that Whisper Tech and its technical director Don Clucas, developed the Stirling engine and wobble yoke design first, then looked for suitable applications, not generally considered the best way of bringing a product to market.
There are currently about 400 hand built WhisperGen units in the United Kingdom and Europe, with a timeline to supply and install 80,000 mass-manufactured units over the next 5 years in the United Kingdom. The manufacturing facility will be located in Spain. And so far, there doesn't seem to be any effort to distribute WhisperGen in the United States. At the present time, all orders are on hold until early 2009.
At the time of this writing the US dollar is plummeting, so perhaps it's not a good time to be considering import goods due to a weaker buying position. That being said, here is cost information for current models iin Europe.
Early handbuilt WhisperGen units run at 3000 British Pounds, converting today into $6226 US Dollars. But price and savings will improve as manufacturing ramps up and energy costs rise. If it were installed today it could save between $300 and $400 in fuel and elecrical bills annually.
As a consumer of oil energy paying $3.11 a gallon this heating season, when I consider upgrading my home heating system, you can bet that I'm looking around for anything that doesn't burn oil. For my needs, the prospect of owning a WhisperGen or another device similarly efficient and economical should come sooner rather than later. I can feasibly wait until 2009 to begin standing in line to order a unit from Europe, but it doesn't appear that the majority of Americans will either be completely unaware of this product even if wehave the opportunity to buy one. Waiting for the WhisperGen to come to America may take as much patience as waiting for the manufacture and distribution of a reasonably priced electric car. With the year 2012 set by international climate reports as the year everyone on the planet should be carbon neutral, it's disappointing that we may not see either the WhisperGen or the Chevy Volt until somewhere around the same time.
The engineering success of the WhisperGen should be heralded worldwide. But there's also a somewhat disappointing side of the story as well — a disappointment that has nothing to do with oil or alternative energy technologies. For me, a lot of national pride is at stake here. American technology reached its symoblic peak when Armstrong first stepped on the moon. Nothing, including recent Chinese rocketry, can take that away from our self-conception as leaders in science, innovation, and human achievement. But the space race is over, and the next race is for energy.
As a result, there is a significant quesiton of how quickly the United States is falling behind in the development of new energy and carbon reducing innovations. France and Japan lead the international effort to harness the power of the sun through a massive experiment in nuclear fusion and plasma technology, from which — even if it fails to reach it's goal — is likely to provide other useful, unaticipated energy appications. The entire continent of Europe virtually owns wind technology. And of course, the Toyota Prius has already become an iconic symbol of the American consumer's new interest in carbon reduction. And now it is the small, isolated, progressive island-nation of New Zealad that is delivering — and will profit generously from — the AC WhisperGen microCHP.
As for American technology? Well, we're still waiting for the Chevy Volt. And even here in the once-leading-edge State of Vermont? We're battling wind farms and returning to the hard-scrabble ways of calloused hands and wood-fired stoves.
Paradise Lost? I think we can make that connection here in America.
