Happy Earth Day!

La Mancha Plains

We just returned from 9 days in Spain. We traveled from Madrid to southern Andalusia without noticing coal power plants, white skies or other environmental ugliness you'd see in many other parts of the world. We did see lots of wind turbines including one huge wind turbine blade on a semi-truck ready to be installed somewhere.

We saw these windmills towering over the plains of La Mancha 500 years after Cervantes described these or similar 'giants' in Don Quixote: windgiants

We saw many solar farms. It was really obvious that Spain is a leader in alternative energy technology. Spain already produces more than 16 Gigawatts of wind power and about 1/3rd of its electricity comes from renewable energy sources. solarispain

We stayed at cortijoloslobos, a horse farm in a beautiful unspoiled part of Andalusia. The white roof, thick walls and other design features help keep the place cool in the summer. The owners took it upon themselves to care for and try to find homes for animals left homeless during this recession. cortijoloslobos

We saw Olive groves and other farms, well suited to the dry Mediterranean climate. Andalucia We drove a Citroen diesel minivan which sipped little more than 1 tank of fuel in the several hundred mile journey from Madrid to Andalucia and back. Why don't Ford and G.M. release their small diesel engine powered cars in the U.S.? We saw more of the moorish architecture with deep set (often star shaped) ceiling windows. When my wife saw these in Istanbul, she noticed that they were very similar to the Solatube we had installed in our Wisconsin kitchen in the late 1990s, allowing in light without heat.

Stars I hadn't seen since my childhood in the southwestern U.S. desert suddenly reappeared in the dark Andalusian night, reminding me that they've always been there just above the smog, clouds and light pollution. Happy earth day! Yes, it is possible to enjoy the best of this earth and still leave something for the grandchildren.

Edison bulbs banned in E.U., why not ban PCs too?

I can almost understand why governments are trying to force us to use CFs. CFs are functionally equivalent to incandescent for MOST applications while using 1/5th to 1/3rd the wattage. But if we can overlook edge cases, why stop with light bulbs? Sun Rays are functionally equivalent to desktop PCs for MOST applications while using only 1/40th the electrical power. Replacing PCs with Sun Rays would saves between 8 and 13 times as much as moving from incandescents to CFs. So why not ban desktop PCs?

lights out for earth hour

World Wildlife Federation (WWF) is sponsoring the first earth hour. If you'd like to participate, just turn of your lights (and other excess energy consuming devices)...

Outsource your IT energy consumption with Sun Ray

I worked a few days from my home town, Racine, Wisconsin because it was the most convenient stopping off point for our trip to a Caribbean Wedding (You might not have heard the phrase, "Wisconsin -- gateway to the Caribbean?") During one Wednesday evening sailboat race I looked back at the base of the new smokestacks which will soon dominate the skyline over Wind Point penninsula. Two years ago the Wisconsin Public Service Commission made the unfortunate choice of continuing the almost exclusive dependence on coal energy. The construction of two massive new coal power plants promised to bring much-needed jobs to the area and here, deep in the rust belt, that's all it takes for almost any project to have overwhelming public support. The thermal pollution alone will impact an area of Lake Michigan the size of West Virginia.

Few people want such behemoths in their back yard but most of us use the services this electricity provides. The Great Lakes states aren't ideal for most alternative energy sources. Norway and California have higher mountains for hydropower, Iceland and New Zealand have more potential for geothermal, Florida, Texas and North Africa have better potential for solar energy. Ideally we could transport alternative energy from places where it is more easily produced. For example, Ireland could produce 7 times its energy consumption in wind energy. Denmark occasionally produces more than 100% of its consumption from wind power and Iceland is close to acheiving carbon neutrality by utilizing its geothermal and hydroelectric resources. But overhead power lines add their own visual pollution and provide a vulnerable target for lightning strikes and wind damage. Until stable, room temperature superconductors are a reality, I\^2R losses will make it impractical to plug our PCs into a cheap utility halfway around the world.

But then I thought about the energy I was using while working remotely. My Sun Ray client was consuming about 4 watts of coal power, the monitor consumed another dozen or so but my local consumption was much less than it would have been if I'd used a Windows P.C. Most of my IT energy needs were being serviced by a utility in Ireland and a percentage of this electricity was generated from an offshore wind farm. I was working squarely in coal country where every kilowatt/hour I consume produces over 2 pounds of carbon dioxide, but I was using wind power. Could this be extended to corporations and expanded so that IT service providers could set up their servers where energy is cheap and clean? I will tell you that it is technically possible. I had expected that the trans Atlantic use of a Sun Ray client would be slow because of the latency in what I assumed would be one or more satellite hops. But for what I was doing (email, terminal, web browser, office applications), the Sun Ray performance was fine. In fact I found that for email it was faster than the laptop. When I select a message on the laptop, the entire contents of the email had to come through VPN from the IMAP server to the client on the laptop and rendered on the screen but when I select a message on the Sun Ray, most of the work was being done locally on the server in Ireland and only the relatively small final rendered email text was compressed and transferred to the client. I intended to video the Sun Ray vs Laptop comparison for upload to joost and demonstrate that I could easily run the client from a couple of cheap 1 foot square amorphous Solar panels but I ran out of time.

Someone could profit from this by advertising: "Reduce your IT energy bill and carbon footprint, move your IT business logic to our servers in sunny Australia!" (or windy Ireland, wavy Scotland...) Would this work? Do real-world companies, governments and other IT consumers pay for the hunk of hot hardware on their desk, or do they really just want the service that that hunk of hot hardware provides?

I suppose by posting this here I ruin my chances of being the world's first IT energy consumption outsourcing consultant but I like working for Sun and if someone else succeeded at this, it would be good for everyone... except possibly the guy who had planned to sell 1215 train car loads of coal to WE Energy's Oak Creek plant every day.

Fraunhofer Institute study shows economic and ecological advantages of thin clients

A recent study by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT in Oberhausen, Germany showed that thin clients can significantly reduce costs, energy consumption and CO2 output. The study considered production, transportation, use and disposal phase of traditional "wintel" PCs vs typical thin clients and the servers necessary for their use. While its important that a respected institute for environmental science did this study, in my opinion, the study underestimated the potential savings in energy usage and CO2 output. The study did not specifically consider Sun Ray ulta-thin clients (4 Watts), but even the 14-19 Watt IGEL thin clients considered in the study required much less energy than a typical desktop PC (68-96 Watts) in the use phase. The study concluded that, "Even when including the cooling power for the server, which has been estimated conservatively as twice the required power, thin clients use significantly less energy than PCs (factor 2)".1 Obviously when you add production, transport and disposal costs, thin clients win hands down. Thin and ultra-thin clients don't yet meet the average hacker or gamer's desktop needs, but for most enterprise uses, the advantages are becoming clearer every day. You can find a pdf report on the full study here.

1The study appeared to overlook the fact that typical enterprise use of desktop PCs also requires a server.
