University budget - copy+paste+pray... or WAKE UP!

University budget cuts while the obligatory short sightedness continues - I had enough and had to put my head on the chopping block! We are experiencing severe budget cuts to an extent where there literally is no money for research after (some of) the payrolls have been secured. I am submitting the article below to the university newspaper where I work (Estonian University of Life Sciences, aka EMÜ) in Estonian.
I know I do not have The Truth and the Glorious Facts which others might have, but at least I am making honest attempts of finding a way out. I thought the article fit the topic of the blog and added the English version here.
Crisis?
It is easy to cut down on budgets. It is perhaps easier to make savings into continuous profit. I would like to suggest EMÜ directors several strategies that can do that.
I work with parasites at EMÜ. To me it is obvious to see the same general survival strategies are used by cooperate firms as seen in the biological world. We have to live with them because we are too weak and starved to expel them. Just like getting rid of a parasite infection will give you surpluses in health and economy, so will independences from licences and resources.
Here are 4 ideas EMÜ can apply to save vast amounts of money.
  1. Replace expensive licences with open source.
  2. Make internet telephony standard
  3. Become an green independent university.
  4. Make savings self-perpetuate in the budget.
The software licenses are expensive and almost without exception, unnecessary. Open source programs such as Open Office can replace most tools used on the computer, for free. Though it is mainly myth that licensed programs can do more and are safer than open source, individual exceptions can be made to satisfy sceptics or specialists – opposite of the current strategy.
Skype is already standard many major firms because it is free and ridiculous cheap use compared to standard telephony. A headset and web cam cost less than most of us pay for a phone bill each month. A hand held phone that can use Skype through the WiFi network cost less than 2200 EEK. It does not take much imagination to manage a credit system for those calling non-Skype networks, and for monthly unlimited world wide use of landlines cost less than a meal in the university cafeteria for 3 persons. Why pay for both internet and telephone when you only need to pay for one?
Being "green" looks good. Being "independent" works! EMÜ has all the facilities to implement technology that provide free heat and electricity. Already working radiator systems, water tanks, and flat roofs (even south facing tilted roofs) are begging for solar heaters and sun cells. The university has several hectares of land for pipes that could provide buildings with heat through ground pipes and heat pumps. These technologies can easily be rejected as options when buying them from firms who sell and install each of the items for around 100.000-150.000 EEK at household size. However, most items can, and is, easily made by untrained hands at a quarter of the price or less. I would love to share my knowledge and be part of such a project at EMÜ – because it is fun and it makes a lot of sense.
Most of us do not make use of the above methods regardless of their obvious and proven benefits. It can be difficult convince oneself to find that extra financing to invest in a method that will save you money. So, if you succeed making the first baby step and save something on your budget after the initial investment is paid back, immediately invest it again! The second step is much easier when there is nothing to loose any more - your overall expenses are the same with the savings reinvested. The self-perpetuating strategy can makes the progress possible. Normal strategy would be to put the savings into the bag of money, look at the minus on the bottom line, and say "sorry, there is no finances for it this week/month/year". In stead of staff taking extra holidays, perhaps they should build sun panels?
We got the tools, let us grow the will!

To Grid or not to Grid

I write a lot about renewable energy because it seems to attract inventors, engineers, and scientists alike. It thus is a good focus point for the paradoxes these problem solvers meet when trying to solve what seems to be in every ones interest (global warming, energy supply, pollution). The topic of this blog.

The New Scientists brought an article the 3rd of December 2008 on an increasing trend of people becoming independent of the power grid suppliers (How to unplug from the grid). More and more people apparently seems to dump the high cost of establishing new grid connections, or just sleep with clearer consciousness at night, and become self-sufficient with heat and electricity. I felt this myself as am building a house now. Just getting permission to use an existing connection to the house cost me over 1000 Euro ("connection fee"), and once again for using extra amps.

Prices are dropping and efficiency on equipment (sun cells/panels, wind mills, electricity storage devices etc.) is improving (see previous blog entries). It is becoming affordable and doable to replace outdated heating/power systems in your own home.
These days it seems that we, the people, are taking or demanding more and more independence at the same time the governments are tightening the control. Whether it is named "Web 2.0", "civil disobedience", "anarchists", "activists", "interest groups" or whatever - we are organizing and not waiting for our leaders to solve the problems. And the firms can smell the profits to be earned from this new movement. From my chair these changes in mindset is causing many clashes in our world today.

In our case of independence of the grid the conflict of interests, the paradox, seems to become apparent in the problem of producing too much energy as a private, independent, energy supplier. In Germany and the previous blog entry on Ota City, the private power generates are allowed to channel their excess electricity into the power grid, and take out electricity when unable to sustain themselves with power (see picture). The power grid functions as a "battery" so to say. Simple, easy to calculate, manage, and beneficial for all parts (the power company sets the prices). But it is very few countries who use this option. Why? Perhaps it the existence of a monopoly situation on energy supply as it is now. Letting go of some of this control may be difficult. However, it does not lead to non-fossil energy anytime soon if the power companies are expected to become "green" anytime soon. The companies has billions invested in power plants that are not easily rebuilt for new energy scources. So economically it is not rent able.

So, we can easily supply energy clean an efficiently from the sun or wind, but storing the electricity is a problem. The solution is simple, and already existing and working in places, but requires acceptance of power companies. Sad but true.

Perhaps we will see independent power suppliers organizing alternative grid networks in the future. Teslas wireless transfer of electricity is currently only use ind tooth brushes and art installations - but potentially could become a new grid network ("Change must come through the barrel of a gun").

Sun cells running a Japanese city

Sun power is the absolute largest known source of continous free power on earth, but we are currently quite bad at harvesting it.

The Danish news channel, Politiken, presented a news reel today (by Clavs Sylvest) on the Japanese Ota City that is being fully self sufficient in sun powered electricity.

This is a goverment sponsored program including about 500 homes. Each home has been given sun cells. The project is a national experiment testing how to avoid power cuts with the use of sun power. The house owners are allowed to sell the electricity back to the power compagny when producing excess electricity. This amounts to about 50 US dollars/month per house, on top of the electricity saved. However, sun cells are still expensive to produce and buy, and not using the electricity optimally due to reflection.

Good news though, Rensselaer Polytechnic Institute (US, also source of foto) has figured out how to coat the sun cells with tiny hairs that capture the otherwise reflected sunlight, much like hairs on a polar bear. The improvement allows the cells to harvest close to 100% of incoming rays, in contrast to about 67% now. So let us hope this will arrive on the market one day, that goverments will support people buying them, and that power compagnies will buy surpluss energy.
