    Better if biofuels are used as... fuel.

    It's difficult to grow enough biofuel to provide electric generation... especially in a province that sells itself on "natural" beauty.

    I could name a few easy ways to provide reliable tricycle operation in the area.

    One: Run a converted carburetted tricycle off of digester gas (methane) collected from sewage reclamation. You could charge your e-trikes off of this, but you're adding two more steps to the energy chain, which would make it less efficient.

    Two: Convert tricycles to run with 1,000cc Kubota diesels. Run them off of waste vegetable oil sourced from the resorts and restaurants. Given the number of commercial operations on the island, you could run several of these vehicles easily off of the wastes.

    Three: Pedicabs. They're more environmentally friendly than anything else.

    -

    For an efficient electric service, I'd prescribe an e-jeep, built from the ground-up as an electric (hence, not a converted multicab, but a road-going Golf Cart / UTV. Give it twice the battery capacity needed and then ensure that the battery level never goes below 40%. In other words, if it has a 50 km range, only use 30 km of that.

    Most rudimentary electrics here don't have that safety valve that prevents you from fully draining the batteries. Lead-acid aren't as vulnerable to overuse as lithium, but draining them fully is still bad.

    Then budget to replace the batteries. Most lead-acid electrics here seem to only get 2-4 years out of their battery packs in constant use. This must be part of the project budget.

    Ang pagbalik ng comeback...

    A 13hp 400cc diesel engine would already be enough for a tricycle. Waste vegetable oil is a reasonable option to use as fuel because it doesn't require the chemical reactions to be turned into biodiesel, altough the glycerin from the oil is quite hard to burn properly. I'm favorable to direct-injection engines due to the higher injection pressures but to use WVO an archaic indirect-injection setup is still often quoted as a better option due to its higher temperatures.

    why not let market demand for EVs evolve by itself?

    when there's demand there will be supply there will be infrastructure (charging stations, battery recyclers, whatever)

    let evolution run its course

    but noooo

    environmentalists in govt keep pushing EVs

    pansin niyo walang independent end user bumibili

    it's all govt

    it's driven by ideology. environmentalist ideology
    Driven by "popular vote" for next election. hehe
    Fasten your seatbelt! Or else... Driven To Thrill!
