    Usapang alternative fuel. But in this case, alternative car ang nangyari. Well it's nice to have na marami ng option sa kotse. May mga mumog gasolina at meron din halos katulad ng motosiklo lang.

    My suggest, you dont really need to sacrifice so much in choosing car u don't really like. Check this out, something that will save us from a very high fuel expense at the same time environment friendly pa. PLUS 50! 50% more fuel mileage and no conversion needed.

    *ddcspot - i am a bit skeptical about this "Plus 50" fuel saver. the link you gave just provided some vague information about the product.

    This is definitely new especially for many people...

    I hope this technology will prosper...

    "Drivers also will be able to plug into the electrical grid and use the car’s built-in compressor to refill the tanks in about four hours"


    this is the biggest downside so far. no one will want to wait 4 hours to "fuel" a car that will run 100+ miles or so. but couldn't they make a compressor that won't take as long?

    4 hours is fine for an on-board compress capable of producing thousands of PSI in pressure. It's a "recharge" at the office thing. Anyway, the main market of the air-car would be the daily commute crowd and not people going for a long drive in the province.

    yes, of course, you can have higher powered compressor, but it would be big and heavy and it would require a dedicated power outlet to handle the power

    the 4-hour compressor is probably the practical rating that can be built-in into the car and can be plugged on a typical household outlet

    infrastructure na naman problem nyan ... you'll have to build huge powerfull compressors for stations and the problem is a lot of people aren't smart enough to invest for the future

    re the air car's tanks rupturing - maaring mangyari po ito, ngunit ang dalawang dulo ng tangke ang at risk of rupturing out wards towards the front and the end of the vehicle (i.e. more or less safe yung passengers sa itaas) - this is because this is the area where the welds are located. also po, divers are strapping these tanks to their bare backs for years and accidents are rare po.

    re engines - i believe australia is already using air powered vehicles - mostly in their golf-cart sized vehicles.... the engine used by the australian model is based on the wankel rotary engine (yes, the same kinds used by mazda sports cars). advances in materials research have made this technology feasible. the rotary engine is surprisisingly small, but has much lesser power loss since the flywheel axle is fitted right in the middle of the engine, eliminating the need for camshafts, pistons, piston rods, etc... (wikipedia shows a detailed construction of the rotary engine).

    the air rotary engine shown in discovery is the size of a large pail, but it has sufficient power to drive the golf cart on compressed air.....

    dagdag lang po,

    since the energy required to start the car moving consumes more fuel, mit students were able to take the energy from applying the brakes into charging a small airtank. the compressed air is then released whenever you will start to press the gas pedal. the car will start its movement using compressed air, and you can shift directly to 2nd gear na.this enabled their model car to get upwards of 25kms / liter.

    imagine if this technology was applied to the aircar. meaning everytime you apply the brake, you activate a compressor that automatically recompresses the air tanks - sa haba po ng trapik sa metro manila, baka ma-overcharge pa yung tank.....baka po no need na po to recompress using the generic electricity-driven compressor.

    You might want to avoid going into discussions about perpetual energy because perpetual energy is ranked among Daniel Dingle, etc....

    not really perpetual energy sir, but rather more efficient use of energy, in such a way that waste is minimized.

    braking is one such waste area. all that energy from stopping the car is translated into heating up the brakes.

    anotehr example is shifting to 1st gear from a standstill. this part of driving uses much more fuel because energy is needed to overcome the static friction from the tires ( and thereby moving the weight of the car).

    no system is perfect, there will be always energy losses (friction, heat, etc..)

    in the case of the air car, instead of a sudden drop in pressure when you have used up the stored air in the storage tanks, you might be able to "extend" the charge / pressure a bit (through recirculating / rechargin the air tanks via the brakes), just enough so that you can make it to the next refilling station.

    also sir - electric car inventors are working on a "reverse magnet" - a brake that relies on magnetic repulsion in stopping the car,and producing electricity in the process - thereby recharging the batteries.

    unfortunately you mentioned in your previous post about never needing to recharge and possibility of overcharging the system. You are going into perpetual energy territory.

    Unless you have been under a rock in the last ten years... the system has been in use for years. It's called regenerative braking.

    cool! so these things are not so new after all....its sad that we dont see them from our favorite car makers......kinda makes one think na magkasosyo sila ng mga oil companies.....

    Car makers have been doing research into alternative cars for decades thats why we now have some hybrid cars on the world market like the Toyota Prius, Honda Civic hybrid and such. But research can be slow since the main problems of the hybrid and electric cars are still the range of the battery system and the total cost of the car.

    Hybrid and electric cars are still waiting for further development in battery technology to improve range and lower total vehicle costs to make it more acceptable to a wider market.

    Example, converting a standard Prius into a plug-in hybrid car with additional battery pack(s) (to increase electric-only range) almost doubles the original purchase price of the car. Given the SRP of this car is already at the P2M range, this option is only viable for the ones very dedicated to the green movement with deep pockets.

    im kinda curious just how "slow" the research can be. look at LPG., it caught on fast, less than a decade (more or less) and look at how much the technology has progressed. its mainstream now.

    whereas the hybrids, which directly threatens the oil companies' main buyers, has been in the works for decades, and still has not yet become mainstream.

    they did introduce the prius and the civic hybrid - but made its pricing so inaccessible that only the uber rich can afford it. why not mass produce the thing and have the research cost spread out over a much larger number - thereby driving down the price?

    re range - while range might be an issue in the U.S. , here in the phils - where the daily commute in cities are less than 100 kms, these hybrids have huge potential. also, why not make 2 seaters? ive been to work all these years and 90% of the time its just me or at least one other passenger. smaller size increases mileage....

    it is also interesting to note that the devt of lpg's were led independently - i.e. it was not dependent on the big automakers' research efforts.(please correct me if im mistaken re this point).

    perhaps the private sector outside the automaker's circles will need to step in and "turbo boost" the development of vehicles that relies on alternative sources of energy.

    peace po

    Auto-LPG first appeared in the 70's during that decade's fuel crisis. After that, a slow but steady progress in design and development in certain countries helped push auto-lpg usage to become more mainstream. It didn't happen as quickly as you think.

    It is only in the past few years that we are benefiting the decades long development of auto-lpg in other countries.

    The technology to produce a hybrid is expensive, hence the high cost of hybrid cars. You are literally putting two propulsion systems into a single vehicle. One is gasoline or diesel fueled and the other electric. That alone would result in a car costing much more than a standard car which only has a gasoline or diesel engine under the hood. Then add the cost of the battery pack and the power regeneration system.

    If hybrid cars get cheaper, it would be a good bet that cars with only one power system (gasoline, diesel or electric only) will be even cheaper.

    Hybrids cost too much for the simple daily commute. A pure electric car would be a better solution but more affordable electric cars like the G-Wiz can go less than 100km per full battery charge.


    it is also interesting to note that the devt of lpg's were led independently - i.e. it was not dependent on the big automakers' research efforts.(please correct me if im mistaken re this point).
    Mostly independent although some car makers did produce LPG fueled engines straight off the production line like Toyota since in Japan certain car models are meant to be fueled by LPG (Crown Taxi cabs).


    perhaps the private sector outside the automaker's circles will need to step in and "turbo boost" the development of vehicles that relies on alternative sources of energy.
    Easy to say but without big profits as incentive, it would be a very slow boat to anywhere.

    Example, the TESLA electric sports car. High performance electric car that also has a high performance price tag.
