    I saw this on youtube. A very useful invention - cars that run on compressed air. This is very good. Finally an alternative to petroleum products. Watch this.

    However, this project did nor push through because it is too expensive to compress air. Therefore, this project was abandoned.

    Lugi ka in terms of energy balance pagdating sa conpressed air vehicles. Mas malaki kailangan na energy to compress the air than the energy produced.

    Air might be free but the energy used to propel the car comes from the high pressure from the compressed air. Compressing air requires lots of energy.

    There is no "free lunch".

    Yup. Nakakapanghinayang lang. But maybe we can harness other sources of energy like the movement of pavements / roads when people or vehicles traverse over them. Baka we can collect those "movements" convert them into energy, store the, then use them to propel our cars.

    More effective to turn it into electricity.

    Air compression and storage is very energy-wasteful. Charging batteries from that movement or turning it straight into electricity to power something is more useful than using pavement movement to generate electricity to run an air compressor.

    The most developed of "air cars" have never shown much more than mediocre range and performance.

    Yup, at best, air powered motors are only good in power tools and some toys.

    Which reminds me of my old air power toy car from decades ago. It had a one cylinder engine and goes quite fast but only lasts a few meters before it runs out of compressed air.

    Ah. You had good taste in toys, sounds like the Tomy air car. Mine was red and black...



    One of my all-time favorites. Tomy was THE toy company of the 80's and 90's.

    All my cars run on air ... and gas ... mixed and compressed, add a spark ... boom! Hehe

    It would be more efficient to use all the hot air generated in the Senate and Congress to produce electricity.

    Nice idea na gamitin ang air. Nakikita ko lang na problem dito e panu mo gagawin sa mas malalaking car.. Sa mini car lang siya possible kasi yung torque niya e mahina.. If ever na ma dedevelop pa nila ito na tipong air efficient ang engine e panalo ito sa market. Tatalunin pa nito ang electric car..
