Battle: Dar es Salaam vs Nairobi

[dopchinski]

Wacha ujinga wako, onyesha nchi yoyote Ile duniani ambayo ndani ya miaka ishirini iliyopita imejenga reli isiyotumia umeme kwa kisingizio cha kubeba mizigo.

Kwa taarifa yako, electric locomotives Zina nguvu ×2.5 zaidi ya zinazotumia Diesel. Nenda kasome topic ya "Mechanical advantages za Diesel vs electric engines/Motor.

Mechanical advantage ya diesel engine haizidi 35% wakati Ile ya electric ni over 90%, ndio sababu train za Tanzania za mizigo zitavuta tani 10K, wakati Kenya zinavuta tani 4K tu, kwa train Moja ya mizigo.

it's a 'local passenger only' rail.. as in, electricity driven locomotive is too weak to ferry multi tonne cargo.

(some electric engineering vybe here👇🏽)
an electric locomotive cannot carry very heavy cargo because it relies purely on electric motors to make it move. and you knw whts inside a motor is coiled wires tht rotates by virtue of a magnetic field!.. hence their is a magnet in every motion tht will be driven by electricity.....

Clearly you lack some basic knowledge of physics.

In physics, "energy can neither be created nor destroyed but it can be transformed from one form to another" (1st law of thermodynamics).

Anytime we make this transformation, we tend to lose some energy into other forms. Electric motors convert electrical energy directly into mechanical with little energy loss, which classifies it (electrical energy) as high quality energy.

A high quality energy source is the one that can easily be transferred into other forms with little loss.

In contrary, diesel engines have a slew of processes to go through to form some mechanical movements to the wheels. Firstly, chemical energy (diesel) is converted into heat (energy is lost due to heat dissipation) to form potential energy (piston moving up and down). This movement of pistons creates a lot of friction (energy is lost due to friction, heat dissipation and vibration).

At this point we haven't gotten to the wheels yet.

Pistons then move the crankshaft (friction) which goes through some gear mechanism (friction) and lastly that energy is transferred to the wheels. At that point the efficiency is already lost by 70%.

now to my point!
can you realy rely on the strength 💪 of a basic magnet to carry heavy tonnage!?.. the answer will be definitely NO. but for carrying passengers.. yes.

Traction motors (induction motors) don't use "basic magnet" (perhaps you meant to say permanent magnet), they constantly "create" magnetism when alternating current is applied.

my conclusion:-
fossil fuels is the real deal when it comes to strength,

What do you mean by strength?

that's why you find all earth moving equipments eg. bulldozers run on diesel. all heavy goods tracks on transit run on diesel, all cranes and folklifts at a seaport also rely on fossils, and so is the heavy cargo train locomotive..

yatafakari hayo kimya kimya 🤫🤫

It's because we can stored some chemical energy (fuel) in a small container that fits into the equipment. With electrical powered equipment we'll need a large amount of batteries, powerful enough to run those machines for some times, at the moment its impractical. Electric trains don't have that problem as they move in a straight line along the power source.

a very weak dude this one, that only relies on a magnetic field to run!👇🏽View attachment 2301182so this project as a whole is a huge white elephant 🐘!. local passengers only! and no cargos for neibouring countries means very little profits. it will hardly pay back itself 🤫🤫

A better term would be magnetic flux.

Halafu hii maneno ya kupanda bei ya mafuta itakuja kumliza mtu kipindi SGR inakamilika halafu JNHPP inakamilika pia! There is no way SGR Kunyaland itahimili ushindani dhidi ya SGR Tanzania!

It's Ok to give props to JPM for envisioning that.

these are duos, two-in-one rail line. as in you can either use electricity or fossil fuel.. coz what i knw is tht, electric trains in transporting cargo is still under development 👇🏽👇🏽

this was last year in the US. still under trial my beb

first let me congratulate your physics teacher for a job well done..👏🏽

i truely concur with your vast knowledge in the field of physics...

but yes.. this is what i actually ment!👇🏽

your electric train whatever, duly relies on the 'Permanent Magnet!',
and infact all 'Motors' relies on permanent magnets, and for which case it yields a weak 'magnetic flux' since its a natural constant magnet, as compared to the 'Electricaly Induced Magnetic Flux' that involve coiling an electric charged wire through an Iron Metal.! coz this type of magnets tend to yield untold quantities of Magnetic Field/Flux that is cable of lifting a whole car!🙀 infact this Induced Magnets are mostly used in lifting heavy scrap metals including damaged vehicles..

but that's not the case inside a 'Motor' where permanent magnet is needed to produce electricity itself, and not vice-versa.

i went to school, i also know this thing bhana! 😆😆 acha kutubeba ufala. kubali tu matokeo, wacha ku 'Induce' vitu ili tu mradi ku falsely justify your argument!😆

eti umetaja kisumu!?🙀 riswa shetani shindwe!

coz me wht i knw is tht, only 10% of kisumu is considered as Slums.. tht is Nyalenda, Manyatta and a small section of Kondole estate, the rest is pure tranquil and leafy affluent homes..

upto 85% of the whole kisumu city is captured in this pics here👇🏽 but still cannot trace any form of slum..🤔
