There are trams run on flywheels.

It will reduce the cost of the whole shebang.

You only have electrical ports at each station that spin the fly wheels up to speed at every stop.

Sabagay, if the distance is short, it will work.

Now I'm curious enough to go visit...

Mas mura siguro kung nag electric/cng buses na lang. Pero nung nag-trial sila dati nun, nagstrike lahat ng jeep. hehehe

Electric buses are still economically infeasible. Rangewise it'd be very limited. Pricewise its easily 2.5x as much as a new bus. The replacement battery alone is worth more than a new engine.

CNG's economics can be justified if you have a wide enough distribution network.

ALthough electricity might be cheaper... the cost of the batteries is very expensive and batteries do wear out and need to be replaced after their life cycle is done. The life cycle can vary from 500 to over 1000 cycles.

The batteries used in e-buses are Ferrite-carbon/Li-Ion. Heavy, durable, but very expensive.

I'm talking about UP. For smaller routes, it might be better to look at electric of cng buses. UP is capitalizing on infrastructure which might be as expensive as having small electric or cng buses.

For trains, I'm guessing we might be better off with BRT than trains because BRT technology can be easier and locally developed.

UP already has a few e-Jeeps. They could run electric routes, but I'm thinking up-front and battery costs are holding them back. Wthi daily use, you're looking at reinvesting about 100k in batteries into each e-Jeep every year or two.

For a dozen units, that's 5m up front, and a miklion reinvested every year and a half.

And that is the problem. Rechargable batteries, no matter how good the performance, will eventually wear out and need to be replaced. Given how things are done in the Philippines, the e-Bus might end up in the junk pile behind cityhall because all the propaganda that came with the initial purchase of the eBus would have faded from pinoy memory by the time the battery wears out and no additional budget is set aside to purchase expensive replacement batteries.

A bus will practically use as much fuel as its worth within a little over a year.

All these are about business cases.

If for instance fuel prices double, then its pretty easy to justify an E-bus that needs to replace its batteries every 2 years.
