"e-Jeepney" - The electric powered jeepney

[ghosthunter]

That is nit-picking gh. HP is directly related to work while megawatts needs to be converted to HP so as to allow work.

Still nit-picking...

Horsepower and watts are both measures of "power". Just one is in english and the other is in metric.

Like in the conversion formula:

HP x 746 = watts

or

HP x 0.746 = kilowatts


In the same way that a car engine's output can be measured either in horsepower or kilowatts.

Anyway, producing free electricity is a doable thing is the bottom line and this can make e-jeepneys viable.

Nothing is really for "free". Just because you don't pay for the raw materials, doesn't mean it's free.

Even with a methane power plant, you still need the labor to run and maintain the facility. Also transport cost for all the "organic matter" to the plant's location (unless you have a big animal farm in the middle of Makati City). Taxes, etc.

"Free" is an illusion.

Perhaps you should visit a farm of the out house an d see what is free.

Yeah, but gathering and bringing the smelly SH*T to Makati is not free. Plus putting up, running and maintaining the million peso biogas generator is not free. Comprendes?

What school did you go to, BTW?

Yeah Kitsons, you should ask for a refund from your school.

Like what I said earlier, transportation is not free unless you have a unknown farm located right in the middle of the City of Makati to go along with that imaginary methane fueled power plant supposedly located also in Makati.

Just to add, human labor isn't free as well. You need people to shovel all the (literal) crap from the farm into holding tanks and then to pump all the slurry into a tanker truck to transport it to the imaginary methane power plant.

And then on top of that, after the slurry has been "digested" by the bio-digester, you will need the used slurry to be transported back to the farm to be used as organic fertilizer.

So much for being "free" ...

Could not fit in message the detailed amounts of different biodigester feeed stock as many kinds of excreta, human and agricultural crop waste produces and how much biogas iis produced per kg of feedstock to show all factors quantifiable that can be averaged to a minima/maxima extrapolation to allow proper designs for really efficient methane production as pasted below are some data on biogas production:

Biogas is a mixture of gasses, composed chiefly of:

methane (CH4) 50-70 vol.%
carbon dioxide (CO2) 30-50 vol.%
others, including, - hydrogen (H2) 0-1vol.% and, hydrogen sulfide (H2S) 0-3 vol.%

Heating value (The number of kJ liberated by the complete combustion of one cubic meter of fuel) of methane is 35906 kJ/m3 or 8576 kcal/m3. The heat value of biogas consisting of 60% of methane and 40% of CO2 is: 8576 kcal/m3 × 0.6 = 5146 kcal/m3

The calorific value of biogas is about 6 KWh/m3. This corresponds to about 5.5 kg of firewood. The net calorific value depends mainly on the percentage of methane and efficiency of the burner or other appliances. Methane is the valuable component under the aspect of using biogas as a fuel. The characteristic properties of biogas depend on the pressure and the temperature that prevail during its generation. They are also affected by the moisture content of the substrate to be digested. The specific gravity of biogas, in which its composition is 60% of methane and 40% of CO2 is 0.94. Therefore, biogas is lighter than air. Biogas with 60% of methane and 40% of CO2 has density of 1.2196 kg/m3.


Hydrogen sulphide and carbon dioxide in the biogas combine with condensed water and form corrosive acid, which corrodes the metal parts of biogas appliances.

Hydraulic Retention Time (HRT)
HRT can be defined as the total time required by a given amount of dung to produce approximately 80 to 85% of the total gas.

I have my doubts if Kitsons even understood what he posted above because the last portion has data/information missing.

So, kitsons, what school & major did you graduate from?

[OyiL]

those who know more about the facts should educate instead of throwing insults. i know that no school includes insult throwing as part of their offered curriculum. but im beginning to think that i have been wrong all the time. ganyan ba turo sa la salle? marg, san ka nag-aral? ganyan be turo sa pinag-aralan mong school? andywest?

kung matatalino at edukado kayo, itama nyo ang pagkakamali sa tamang paraan. matuto kayo magrespeto.

Mukhang dating dito sa thread personalan na. Anyway, am too old na to bother about such nonsense.

I was formerly a BS Chem student at UP and presently my son is also taking up BS Chem and another son in HS signified his desire to take up BS Biochem which my eldest son used to be in but unfortunately, he decided to transfer due to a rather complicated situation that developed while he as still at UST taking up his BS Biochem.

Have actually composed a background to establish credibility but laptop overheated and would have to wait for it to cool so can retrieve what I composed there since a bit long and do not want to repeat the process. Will send it when can retrieve. In it on the last paragraph, I mentioned my being tutored by the late Jose Maria Galza, former dean of engineering at the DLSU and was also proponent and professor with AIM who actually placed me non-credit with his class there at AIM with a bunch of foreigners who held major positions in their respective countries whom we got along and became gang-mates. The experience with them at what we discussed both in the class and outside with them sharing their views and what they actually do being city planner for Singapore, top marketing man for Summit, consultant for del monte phil. and consultants for other MNC's with discussions my mentors often had on his efficiency consultancy with clients as Maria Cristina, Dynetics, Henry Sy, Chemphil among other such companies, gave me a wider perspective in viewing things that I do not believe in thinking within the box but prefer thinking out of the box yet put my feet on the ground as mymentor used to mop me all over the floor wheenver I'd give ideas that where out in space.

I fully understand what I shared as we are presently working on a project that can give free electricity. Of course you are right in that nothing is really free. However, if you put in in the proper management perspective wherein after paying up initial start up expense to setting up the system, maintenance and replacement actually become self-sustaining with incomes generated from the power generation that eventually the financial equation flattens out -- to be, as perhaps comparatively speaking reach the point of unity in mechanical engineering terms.

We hope to get our project moving and perhaps get some e-jeepneys and or utility vehicles moving within the medium term.

I have joined this thread and am thankful for the inputs of Romski and the others who contributed in getting a better perspective of how to approach the different problems that in their experience and knowledge shared, as the problem of battery life and cost among others involved with design.

Have addressed most problem areas with the system we are developing as with what gh shared on accessibility of batteries so as easy and convenient to replace. With such convenience and efficient ergonomics, battery life can be extended by not fully putting into solution much of the lead and copper that they cannot be fully attracted back to the plates with the lessened area of surface of the plates to attach to. This is what actually happens that deteriorates the batteries... more so with the start up batteries where culmat, the only battery plates supplier (as of the early 90's info) actually uses the thread type plates that once the threads are cut, good bye since no way that the plates can re-form to being a plate again and the terminals surface area would not be able to develop enough surface area to have enough capacity to produce the necessary electricity required of the battery.

With the deep cell batteries that are actually the old typ of batteries when the dynamo was still being used and not the present alternator to recharge batteries, if properly cared for can last. Care to make it last is by not using up the electrical charge so surface are of plates arer not diminished to the point of accelerated deterioration. Such deep cell batteries as I remember from childhood used to last even up to five years and maintenance was just average maintenance where when due to inefficiency of the voltage regulator then, charging batteries was not as efficiently managed as the present day computer aided ones.

Hopefully we may get the e-jeepney on the road. the real problem is if the government would have the will to go against the oil companies... of course we can go do as the Viet Cong and Mao with his small band of guerrillas did... they eventually won the war.

BTW. As off hand studies operating a bigogas power generator makes an integrated approach to operating e-vehicle fleets more than free. Projected incomes from two main staple industries of RP would generate incomes that can be raised a thousand plus per cent as is being generated presently.

The key area of concern is maintaining change battery depots along routes where the service vehicles are to ply.

Other area that needs configuring is producing enough HP to carry bigger loads. At present the only electric motor that we know off sold in the market is the two HP one that can be directly attached with the bell housing. Have not fully researched on this as we are working on the design of the micro power generating plants that can produce one megawatt which I was informed by an electrical engineer associate that it would be enough to power up to five baranggays. Can you imagine if every baranggay had such a plant and consolidated into an MPC... tapos na kwento.

Did some computing that for a rural municipality that ranges from 20 to 60 plus baranggays, no more than 20 megawatts would only be needed and the municipality can actually operate e-jeepneys viably since major fuel expense can be eliminated. Kaya lang, la pera dito para sa corrupt kaya only a handful may be open to the concept.
