Diesel and tear gas,could be made with ‘Kassippu technology’
by Chandre Dharmawardana

A common tale of woo today is that “…people… have been waiting in queues to buy petrol, diesel and cooking gas, not just for hours but for days, some of them skipping meals, sleeping on pavements, not for fun, but for survival. Some have lost their lives in the process. Others have almost lost their livelihoods, wasting hours on the streets”
Instead of wasting hours in line-ups, let these people organize, in each community, or street, and form a do-it-yourself group and make their own substitute diesel, using nothing but “Kassippu technology”, as discussed below. In effect, vegetable oils can be extracted from all types of crushed seeds, and leaves, using the simple steam-distillation techniques, used by the bootlegger! Furthermore, there are enough potential sources of inedible vegetable oil to consider this seriously.
Energy is the life blood of modern societies, and any society that fails to consistently supply itself with energy will end up in shambles.
Meanwhile, a news report (The Island) says that the police forces are “thirsting for tear gas” after their heavy use in the failed defence of public properties. There is no need to import teargas when Sri Lanka has potent forms of chillies to source the teargas.
Tear Gas
Very potent forms of teargas can be made, using Sri Lanka’s chilli peppers and “kochchi peppers”. Here again the “Kassippu technology” of steam distillation, and other techniques of oil extraction, using solvents, apply.
The effectiveness of teargas, or the “hotness” of chilli, is measured using the “Scoville Index”. Ordinary sweet peppers (maalu miris) may have an index of less than 100, while “Kochchi Miris” types may reach 50,000 to 100,000 in hotness. A form of tear gas, known as OC, is an oily extract from hot pepper plants. It is emulsified in water, and propylene glycol, or dissolved in organic solvents to make aerosol pepper spray. They may also compound it into a powder. The Army engineers, or the technical branch of the Army and Police, linked to the government analyst, can surely advise on Police needs, instead of using forex to import tear gas. Here, too, what is needed is an adaptation of the technology of the Kassippu man!
Substitute Diesel
This can be made from (i) previously used “waste” cooking oils, (ii) any nuts that can be found in the neighbourhood, be it mee aeta (Madhuka seeds), erandu aeta (Castor seeds), rubber seeds, cachew nut “leli”, tea seeds, domba seeds, kranda seeds, croton seeds, (iii) paengiri leaves, eucalyptus leaves, orange peel, lemon peel, animal fats, etc.
Edible oils, like coconut oil, palm oil, etc., are NOT to be used as they are food.
The oil in the seeds and leaves comes off using the steam distillation part of the Kassippu man’s technology. However, if it is waste rancid cooking oil, no steam distillation is needed; follow the instructions given in the article:
These vegetable oils can usually be directly used in diesel engines, especially if diluted with kerosene, alcohol, or better with ethyl acetate. How to make ethyl acetate using “Kassippu” technology is given below.
Ethyl alcohol and ethyl acetate
The government should legitimize Kassippu making, allowing them to make alcohol from old potatoes, old tubers and other perishables and starchy bio-waste. The Scottish whisky industry came into being when bootleggers were decriminalized!
The modern concept of the precautionary principle is based on control rather than banning noxious substances.
Clean Kassippu is essentially ethyl alcohol in water; it can be re-distilled to concentrate and blended with gasoline (gasohol). However, the correct path is to approve the many attempts to redevelop Sri Lanka’s sugar cane industry and use it partly as a source of industrial alcohol and substitute fuel. The main barrier to the development of the sugar industry has come from Marxist politicians who have joined hands with Buddhist and ecologist zealots who have misread the ecological impact of such industries, by failing to take account of the progress in modern agriculture that provides new green cultivation practices.
Vinegar is weak acetic acid. If acetic acid is cooked with ethyl alcohol the product is ethyl acetate and moisture. However, when it is shaken with the vegetable oil, the ethyl acetate passes into the vegetable oil and the water separates out.
Such a blend of vegetable oil and ethyl acetate can have the right viscosity needed for a substitute diesel, and can be directly used in Diesel engines without any further treatment (e.g., trans-esterification to yield what is known as biodiesel).
Is inedible vegetable oil an insignificant source of Diesel substitute?
Some observers have claimed that Sri Lanka’s non-edible vegetable-oil resources are too small to be relevant. This is incorrect. I will not give my detailed calculations here, but there is strong potential to replace all the diesel needed for Sri Lanka (about one barrel/year per head) if inedible oil outputs are increased using better agronomy. Even now there is easy potential for replacing 30-40% of the needs within one or two planting seasons, even without improved seeds, etc.
I have argued (since 2009) that all of Sri Lanka’s electricity needs, and even double that are potentially available, via the use of floating solar panels on Sri Lanka’s many aquatic bodies (now mostly covered with salvinia and other weeds). The panels cut down evaporation to increase the available water and the hydroelectricity output by 30-40%, in addition to their normal solar electricity output.
King Parakramabahu said, let not a drop of water flow to the ocean without being used. Today, we must say, let no wisp of water evaporate without being used.
Furthermore, you don’t need batteries to store this solar power, because, when the sun shines, you shut off one or two turbines corresponding to the solar energy that is being generated. This energy may be generated in solar panels on Yodha veva, Mannar (a very long shallow veva where evaporation is very high), but even though there no turbines there, it does not matter as the solar energy is fed to the national grid, and so in effect a turbine at Victoria can be shut off to correspond to the energy generated from panels on the surface of the Yodha veva. The advantage of floating solar is that we don’t need to negotiate with private individuals to rent their roofs or upgrade them to hold the weight, etc., or look for suitable land.
All this is has been said before, but to a nation who prefers the easy turn-key solutions that are in the end inappropriate for Lanka. I spoke at length to a group of Presidential advisors and administrators at the Presidential Secretariat, in 2009, and the power point I used can still be viewed, where I had outlined all this and much more.
At that time, floating solar was a new and contested idea and solar modules themselves were very expensive, unlike today. The CEB does not have a research arm to run pilot projects and be a leader in the energy industry. Instead, it has followed the most conservative of approaches to energy planning.

In effect, there is enough electricity, and potential for much higher energy outputs in Sri Lanka. It should set up its own Bosch-Harber urea plant to be run on solar energy!
The “Diyaw, Diyaw, naethnam Kaerali karaw” culture
Sri Lankans have developed a “let the government give, give, or else we rebel” attitude. The culture of innovation and improvisation is applied only for destructive ends or for achieving illegal ends. A country cannot wait for foreign handouts or IMF loans. At least when in dire need it must go for self-help, and eventual achieve a high degree of self-sufficiency in some key sectors, like energy and food.
Every economic plan for a small island nation must include at least partial self-sufficiency in food and energy production. Sri Lanka is not a city state, like Singapore,where a single highly authoritarian government has ruled for decades. Most of its workers live outside it and have no “Singaporean rights”. Singapore is not a paradigm to be followed by Sri Lanka although there are many aspects in their social organisation that can be copied.

‘There are no private universities in Sri Lanka’ – some considerations for higher education reform
Academics involved in education policy like to say that there is no such thing as a private university in Sri Lanka. The only ‘universities’ in the country are state universities; anything else offering degrees is a private higher education institution (HEI). This position is technically accurate. Yet, in the discourse and imagination of the public, private universities are very real – people teach in them, students register in them, families pay fees, and such degree holders enter job markets in Sri Lanka and outside.
For decades, activists concerned for public higher education have ignored or resisted looking at private HEIs, as if such scrutiny would taint them. Others have worked in both types of institutions, carrying practices from each to the other. The apex body governing state universities, the UGC, has, meanwhile, ignored the concept of conflict of interest and appointed individuals in private higher education in committees and leadership positions. It is unsurprising then that some of the ideologies informing private higher education appear in reform agendas in the state sector.
This is a good time then to consider the varying types of private HEIs around us, and to take a look at some of the issues within them in the hope that higher education reform agendas will include private, as well as state higher education.
What is a ‘private university’?
First, some clarifications. In the public imaginary, a ‘private university’ is typically an institution that provides a foreign or local degree for which the student makes a payment. But this broad classification encompasses a host of diverse institutions and types of degrees which I detail below.
The Non-State Higher Education Division (NSHE) of the Ministry of Education has recognised 295 degrees by 32 institutions. Most of these are private companies and include a handful of established, well-known private HEIs that are ‘university like’. The degrees are local degrees conferred by the institutions accredited by the NSHE Division. While private HEIs conferring local degrees must be accredited by the NSHE Division, there appears to be no legal consequence for not doing so. In addition, there are several permutations of the private degree that miss the net of this Division and the Standing Committee on Accreditation and Quality Assurance (SCAQA) that assists this Division.
For one, degrees conferred by foreign universities offered, via these same private HEIs, are not vetted by the NSHE Division. Secondly, there is a growing plethora of private HEIs which have either no physical presence locally or only a dubious presence. The University Grants Commission has notified the public, through their website, that foreign universities listed in the Commonwealth Universities Yearbook and the World Higher Education Database are recognised, but refrained from giving any other details – which degrees? Offered by what modes? These details are not known. Some of the foreign universities in the lists may be legitimate entities in their own land but the degrees conferred locally, in their name, may not adhere to curriculum or teaching specifications of the NSHE Division or the UGC.
Another troubling phenomenon is the ‘top up degree’, which appears to work on the same principle as that of a pre-paid mobile connection: if I have a Diploma or an HND of a sort, I am eligible to complete a course of study which provides me with a degree, usually from a foreign university. The idea that someone who does not initially qualify for a degree programme should be able to work their way towards one is a progressive notion. This is the concept that open and distance learning (ODL) was based on initially, but which is now sadly exploited. ODL models are expected to provide opportunity for learning for those who may be excluded from traditional learning institutions. In Sri Lanka, however, we have seen ODL become a marketplace offering easy to obtain, for-fee qualifications by institutions with little commitment to superior teaching and learning.
Finally, a perusal of the many types of private HEIs and their varied degrees bring to mind another question – how should the private degrees, provided by state institutions (that are not educational institutions), be regulated? Who should do so?
All of these create a host of problems for the public – for hopeful students and parents and trusting employers. For the higher education sector, recruitment of academic staff, too, has become difficult due to this plethora of ambiguous higher education qualifications, as I discussed in a previous Kuppi article (‘Recruiting academics to state universities’).
Some issues in private HEIs – a bellwether for change in state universities
In this second part of this article, I will discuss some aspects of work in private HEIs – albeit the more established institutions – given that such issues may appear in reform agendas in future.
Across state universities, all permanent staff of a specific category are paid according to the same criteria. The picture is not so clear when it comes to private HEIs since they are different entities legally, typically companies. Private HEIs have salary scales and financial incentives that are different to each other. The more established private HEIs reportedly have attractive renumeration packages, possibly a reason for academics of state universities migrating eagerly to such institutions during sabbatical years and on retirement. This may not of course be the case with other less established, or improperly registered HEIs of which we know little. Academic staff of these more accepted private HEIs seem to value the high financial remuneration they receive (in comparison to state universities) as something that makes their work rewarding.
Attractive remuneration is important to sustain the good life and is at times seen as the institution’s way of encouraging good work. Yet, this has implications for the future of the institution: to continue to deliver on promised financial packages, institutions must continue to have large profit margins. One strategy has been to enroll multiple cohorts of students per year, even up to three or four intakes per year. This can result in exploitative work conditions, since staff must cater to all these cohorts in that same year. If there is inadequate staff, employees are further burdened. On the other hand, if there is a sudden drop in enrolments (degrees can go out of fashion) unexpected layoffs occur. Similar to other sectors that employ short-term contract staff – including state universities – in private HEIs, too, individual teachers, who are on short term contracts that need regular renewal, can feel pressured to work under difficult or exploitative conditions.
At the same time, even in the more established private HEIs, work norms differ from those of state universities in that they include promotional work that keeps the institution’s name in the eye of the public. The Marketing (or similarly named) unit comes up in conversations as one of the most important departments. It appears to weigh in on decision-making related to the number of staff, the amount of re-sits per exams, and other pedagogically important matters. This is a worrying example of how financial rationales interfere with pedagogically or academically sound processes, resulting in problematic results in the classroom. On the plus side, junior colleagues, who had experience in both state and private HEIs, also felt that they faced less harassment in private HEIs – primarily due to the private HEIs ability to take swift action in reported cases of harassment. This is a real indictment on state institutions and their reluctance to address chronic issues of harassment in our universities.
Yet, while we hear much about problems in state universities, we hardly hear of problems that staff in private HEIs face. One rationale for a lack of public expressions by staff is that expressions of discontent might lead to trouble given the importance of reputation for private HEIs. The worry about reputational damage is a growing concern in state universities, too, as evidenced by social media policies and internal conversations on reputational damage, consequent to negative publicity. Institutional worries of reputational damage are harmful in the long run since these impact not only freedom of expression by student and staff, but also research that is possible in and about the education sector.
Some thoughts at the end…
A close look at the private higher education sector is important given its strong presence in the country. Impending reform needs to regulate this diverse array of higher education offerings in the private sector, as well as the state institutions that offer privately-funded options of higher education (a topic for a separate Kuppi on its own). It is time we carefully considered how to build a whole system of higher education out of this broken mess.
