RIDING THE GREEN FROG BUS

(Updated Nov. 19, 2014)

Commuting in the Philippines is always a harrowing experience. Hot, rickety Jeepneys, Taxicab drivers who overcharge and ask you to pay a steep contract price rather than use their taxi meter. Drugged bus drivers soaring through the highways and skyways and straight into hell [that is, if you don't get nabbed inside their bus first]. Public Utility Franchises, Traffic Enforcers and Lives are all bought, [ironically,] in the pursuit of the elusive “Hanap Buhay” 1

It is the commuting public who are ultimately at a loss in this state of affairs.

Now this is where the visionary and Entrepreneur Philip Go Apostol coes into the picture. He was convinced that the Filipinos deserve a World-Class public transportation system and thus he founded the Green Frog Transport Company. Touting the slogan “The Filipino Deserves Better”, Apostol aims to improve public transportation in the Philippines by showing Filipinos how commuting is done in First World Countries and to inculcate in them proper commuting behavior so that they can demand the same quality of services from government and private transport providers.

My girlfriend and I finally got to ride the bus.

The Ride

The bus route is from C5 Buting to Taft Avenue and on to the SM Mall of Asia. On our particular trip, we got aboard the bus at the Bus Stop near PNR Buendia. The time was around 7:30PM.  [Click for route information]

The pricing system is area pricing:  A ride in Taguig and Makati City is twenty pesos (P20.00).  A ride in Pasay City costs ten pesos (P10.00) so a trip from end to end would cost thirty pesos (P30.00).  This price may be a bit steep for someone used to paying eight pess (P8.00) for a jeepney ride, but it is definitely worth it. The bus is reasonably fast. True, the hybrid system means that it only accelerates at one meter per second, but it makes fewer stops, because everyone goes on and off at a designated stop.  There is no swerving in and out of traffic and the buses are well maintained so you can be certain that there would be no unforeseen breakdowns.

The floor of the bus is lower than the usual coach that flies on EDSA. This is deliberate in order to make ingress and egress easier. This also means that there are no luggage compartments under the floor of the bus, which is fine since they are unnecessary in a commuter route. What the bus does have is lots of space inside and plenty of standing room: a must during rush hour.

My Girlfriend and I sat at the rear of the bus. And the following are actual pictures taken from our position.

The seats were made of hard plastic, but they were far from being uncomfortable. They were ergonomically designed for the average Asian. They curved so that one could sit snugly. They were not of the bench type so there was no sliding around in the corners. And there was lumbar support, so I could imagine the aged and the infirm sitting on these chairs comfortably. The road we travelled was well-maintained and has a fresh asphalt overlay so this also contributed to the comfortable and not bone-jarring ride.

The conductor, who was a lady was very courteous and genuinely concerned for the safety and comfort of her passengers. She was approachable and when I asked her where I could buy Tap Cards for the bus, she told us that we could get it from her. She politely tried to convince me to buy the Tap Cards on that occasion and it made for a very convincing sales talk.

It was still rush hour when we took the bus so there was plenty of stop and go traffic, but we still felt safe and comfortable. The reasons for this are: (1) cool air conditioning, which points to the fact that the bus is probably lovingly maintained; (2) clean surroundings, which again point to proper maintenance and; (3) reasonable acceleration, the bus does not lurch about as you would expect buses would. I would attribute this to:

(a) driver professionalism and finesse and;
(b) the hybrid drive system.

Because of all these factors, by the time my Girlfriend and I got off the Makati Avenue Stop, we were still comfortable and were not suffering from motion sickness. I could ride this bus everyday, and I would even look forward to the morning commute if this is what I'm getting.

Technical Notes

The hybrid system is not of the diesel electric type in the sense that the motive force of the bus is lies in the electric motors alone (a system I've written about previously, see here). The diesel engine and the electric motors work in tandem with one another. This system has its advantages because of its durability and reliability since it will not allow the electric motors to overwork themselves [probably... ask a automotive expert, not me].

The bus accelerates slowly and I believe that this is deliberate so that it does not lurch about, throwing about the standing passengers. This is no doubt facilitated by the automatic transmission system which allows the bus to accelerate at a constant speed.

Points for Improvement
When I took this particular ride, Green Frog only had 8 buses in its fleet.  This meant long waiting intervals between buses.  But the company according to its Facebook page recently took delivery of new buses and expects a total of 24 buses by 2015 so we can expect to see shorter waiting times.  





New buses will also solve another problem which is crowded buses.  For a bus that charges P20 for a jeepney ride which would only cost P8, the buses do get very crowded at rush hour.  More buses should help with the congestion.

The riders can also work on their discipline when riding the bus.  Specifically in loading and unloading, as there is a designated entrance and exit which riders still tend to ignore.  Though again, this could be a function of congestion as well.

Conclusion

One of Philip Go Apostol's intentions when he started Green Frog Transport Company is to educate Filipinos as to how commuting is done in developed countries—to show us that it is possible to have dignified, fast, economical, clean and safe transportation. The ultimate goal is that Filipinos would campaign and lobby for world class transport.

I've seen what it is like. And I am quite angry that our roads look like this,

and our commuters have to line up for hours,

So I am calling to you, Mr. President Benigno Simeon Cojuangco Aquino III, Chief Executive of the land to help make commuting safer, cleaner, more efficient and more dignified.

1 Hanap Buhay – Tagalog, roughly translated as “Livelihood”. In the simple Filipino mind and Philosophy, it is a justification for all sorts of reckless behavior. It seems to justify the taking of life and property so that one may support himself and loved ones. As though personal prosperity is dependent on the poverty of others. It is the urban-dweller's version of a “zero-sum” game.

Hybrid Cars: Will the Philippines have a bite?

ELON MUSK OF TESLA MOTORS CERTAINLY 
THINKS SO

Updated: 6/13/14

Hybrid cars are getting better and better. They have definitely become more glamorous. Lately, with the introduction of hybrid sportscars and supercars, they have also been pushing the envelope of performance.

I see an opportunity here with hybrid technology. It is a “green technology”, which means that drivers of hybrids will always hold the moral high ground over ordinary internal combustion. Furthermore, as Tesla Motors has proved, it is possible for new players to enter the market.

The hybrid system that interests me the most is the one currently being used by the Tesla. Its formula is a battery powered electric motor for the rear wheels; batteries stored in the center tunnel; and an internal combustion engine which acts as a generator to charge the batteries on the go.*


The Tesla Model S: What arguably started the trend for a 'cool' hybrid


The McLaren P1:  Pushing the Envelope

Why does this system interest me? Allow me to enumerate:

1st It is versatile; a designer is no longer confined to stick to a certain layout. A manufacturer can easily create a rear-engined, front wheel drive car for example. A transversely mounted front engine with rear-wheel drive is likewise possible. A designer could put the engine on the roof if he wishes. The designer is limited only by his imagination.


This picture is from Tito Eusebio Jr, which was posted on the Top Gear Philippines Facebook Page.  Note how the engine may be located on top of the rear axle.  See, with a hybrid, one may position the components anywhere they like for better ground clearance, aerodynamics or weight distribution. 

2nd It is inherently powerful; an electric motor is said to generate all of its low-end power (torque/hatak) instantly. It is for this reason that this formula is also utilized by diesel electric locomotives.

3rd It is very efficient; less power is wasted than in a traditional car with a lot of power being sapped through the friction created in the drivetrain. Regenerative braking can also be set up. The motor can also run at a constant speed unaffected by stop and go traffic. i.e. It need not rev so high when setting off, and theoretically, it can just idle at speed. This is because the engine is not connected to the wheels at all.

4th It can be cheap; the Asian Development Bank is trying to get us to use electric tricycles and local authorities are trying to get jeepney operators to go electric. An electric tricycle costs around P200,000.00 so the cost of a brand new electric motor from China (or preferably locally produced) is probably not that much. Furthermore, since the engine is only supposed to act as a generator, the engine need not be that big. One can ostensibly use an old motorbike or kuliglig engine to power the car.

5th Maintenance should not be problem; an electric motor is built simply with only one moving part. They are very reliable. Jay Leno is said to have a hundred year old electric car that has never needed a service. In any case, if the electric motor is broken, it could be easily removed and overheauled/replaced. Furthermore, since the internal combustion engine is not stressed, it can last longer than one in a normal car.

6th It is environmentally friendly; Its a hybrid!

To be fair, Autocar Magazine found it better than the REVA Electric Car

Drawbacks:

The manufacture of batteries is still very damaging to the environment. 

Towing capacity may also be less than a normal car, this is an inherent limitation of the electric motor.  

Electric motors may also be very susceptible to damage in case of a flood.

Tesla Motors:

Elon Musk, CEO of Tesla Motors recently just "gave away" all of its patents to their hybrid car technology.  He did it because:

According to Musk, Tesla made this gesture to—once again—try to nudge the rest of the automotive market along. Tesla’s Model S has proved that there’s massive interest in a well-made, fun-to-drive electric car. Still, Tesla is barely making a dent in the massive auto market. Musk wants to promote a more dramatic shift toward electric cars, so he will do what he can to accelerate things. “I don’t think people quite appreciate the gravity of what is going on [with regard to global warming] or just how much inertia the climate has,” Musk said during a conference call. “We really need to do something. It would be shortsighted if we try to hold these things close to our vest.”

This highly symbolic gesture is what, in my opinion, is just what the enterprising Filipino Entrepreneur-Inventor needs to get started.  No doubt, as we speak, a Chinese company is out there getting its employees to pore over Tesla's plans so they can copy and improve on it.  This country will only get left behind again. 

Conclusion:

Its high time that the Philipines should have domestic automotive manufacturing business of its own. Perhaps the way to go is with hybrids, especially considering its versatility and advantages. I am quite sure that an enterprising backyard owner jeep builder can come up with something better than the Hammerhead Eagle iThrust that the Top Gear UK Trio came up with. Why not give it a try? How hard can it be?

*I have to admit that I first got interested in the hybrid car after watching Top Gear UK. In one episode, the presenters built a hybrid car from scratch. They used the chassis from a TVR Chimera, an electric motor from a Milk Delivery Van, a diesel generator and a few 12 volt batteries. Autocar Magazine did a review. Read it here.
