Hybrid Cars suffer from certain drawbacks. To overcome these drawbacks, I am proposing the concept of creating a new Greener Car, which should travel a lot longer per gallon fuel and environmental more than enough. This is because a greener car, each time takes brake, recovers brake power to drive itself to save fuel, each time passes over a speed pump it recovers shock absorber power to drive itself to save fuel, each time stops to wait, like at traffic lights, it can save fuel and it should be lighter.
The idea of hybrid cars is to increase fuel efficiency to increase mileage per gallon and to reduce pollution. Standard cars waste fuel because very often the engine generates a power more than necessary. This happens when you change the gear or drive at a lower gear and when you push the accelerator unnecessarily. If your car is automatic it consumes more fuel when you drive slowly. So the idea of hybrid cars is to save the extra generated power and use it later to drive the car and to make it more fuel-efficient. Now hybrid cars also save brake power to drive the car to save more fuel.
To ensure your hybrid car is more fuel-efficient than a standard car, it must not be heavier than the standard car. Otherwise your hybrid car, in addition to the saved power and better fuel consumption, may cost you more fuel than the standard car. An ideal or rather an optimum hybrid car is the one, which is only electrically driven. The engine drives an electric generator to charge a pack of batteries and to drive an electric motor to drive the car. No power is wasted in theory. Any extra power, generated, goes into batteries, which each now and then used to drive the electric motor to drive the car. But there is a drawback, electric generators can produce a viable power only when the engine operates at a considerably high speed. Brake power also saved in the batteries as electrical power.
Let us see if an optimum hybrid car is heavier or not than a standard car. An optimum hybrid car doesn't need a gear box, battery charger and possibly motor starter as well. But instead, it has an electric generator, at least one electric motor and a large pack of batteries. In addition to these, it has extra equipments to convert brake power to electrical power. So three items, one major and two minor, have been removed but four new major items have been added. The problem here is that each one, of these four new major items, could be as heavy as the total weight of the three removed items. In other words, a hybrid car, even if it is optimum, is heavier and could be as heavy as a standard car with more than one person inside.
Accordingly, on the basis of a simple common sense, a hybrid car, even if optimum, may not have a lot of advantages over a standard car in fuel saving because what ever extra generated power saved may not be enough to compensate for the extra weight, which could consume a power more than the saved one. Add to that the disadvantages of batteries used as power storages because batteries, vehicle rechargeable batteries, are not efficient enough. Regardless to these drawbacks, it has been claimed that hybrid cars travel longer per gallon. So how that is possible? This longer travel per gallon mostly must be coming from saved brake power. The contribution of saved engine power and fuel efficiency to this longer mileage travel per gallon may not be a lot and worthwhile when compared with the heavy compromises made for them.
Brake power recovery system of hybrid cars is known as regenerative brake. It is simply an electric generator operates only at higher speeds outside cities, which means a hybrid car also needs the standard friction brake for use at low speeds. This is a serious drawback. It means regenerative brakes are useless inside cities. In addition to that, for practical reasons, regenerative brakes may not be possible to operate with front wheels of rear wheel driven cars.
Having identified some technical disadvantages of hybrid cars, now I am proposing the concept of creating a new car; a greener car, with my invented power storages and, shock absorber and braking systems to eradicate these technical disadvantages. In addition to brake power recovery to save fuel, my proposed greener car also recovers shock absorber power to save more fuel. In addition to that a greener car becomes lighter than a hybrid car and more fuel-efficient.
My invented power storages can replace and take over the job of the large battery pack, electric generator and electric motor. Admittedly, my power storages are going to be heavy but they shouldn't become as heavy as half of the weight of the items they replace. In addition to these, unlike electrical machines like electric generators and electric motors, they need low capital skill and investment. They are going to be inexpensive to make and inexpensive to maintain.
My new brake and brake power recovery system is still the same good old drum and disk brake type but it is improved and frictionless; it is without brake pad and brake shoes, it has the same weight more or less. It works at all speeds and fitted to each wheel. It should be as inexpensive as standard brakes to make and hardly needs any maintaining cost. It doesn't need brake pad and brake shoes renewals and the same disk and drum my last the life of the car. Shock absorbers are the same usual shock absorbers, except they are improved. No longer they release the power they generate uselessly, but now they release any power they generate into power storages for use to drive the car.
Putting all technical details of my proposed greener cars into consideration, when consumer interests concerned, one can confidently say that the benefits of these greener cars are not going to be similar to the benefits of bottled water we buy at supper markets although we can get it free at home. But the benefits of these proposed greener cars, for consumers, are going to be similar to the benefits of energy saving light bulbs. The consumer does get back and saves some thing for sure.
Actually benefits of my proposed greener cars are going to be more than similar to the benefits of energy saving light bulbs, which might be costing double the cost of standard light bulbs to make. The cost of producing my proposed greener cars may be higher than the cost of producing standard cars but it is going to be negligible. So the market prices of these greener cars shouldn't be as high as to force a consumer to choose a standard car over a greener car unless standard car prices slashed by thousands.
These greener cars are not going to suffer from inefficiencies of batteries, electric generators and electric motors. It should save and use all engine, brake and shock absorber powers except what is lost through usual lubricated friction. Once the engine coupled to the power storages, all it's powers put to use. Each time it takes brake at any speed inside cities or on motorways it saves fuel. Each times it passes over a speed pump, it saves fuel. Each time it stops to wait like waiting at traffic lights, it saves fuel.
The job of the engine inside greener cars changes completely. No longer it drives the car. That becomes the job of the power storages. The job of the engine will be to load power storages only. This arrangement can be optimised to put engine operation entirely under the control of power storages., in which case, power storages can put the engine on when stored power falls to a certain level and put the engine off when stored power raised to maximum level. This is an optimum arrangement of fuel consumption by the engine. For example no longer like standard cars, the engine of greener cars burning fuel when they stop at traffic lights. The operation of the engine becomes free from the movement of the car when driven.
