E V that generates it`s own electricity ?

    In this world of making things smaller and more efficient, is anyone researching the production of electricity in a small unit that can be carried by the EV. I E No batteries?

    The reason I ask this is that a small red neck team in Brazil are working on a small power unit with the output to drive electric motors. The fuel is currently petrol but can be adapted to any fuel source in the futue. The goal is one litre of petrol to give a pickup size vehicle about 100 miles range. Twenty times more than current power units.

    Any one else doing this?

    There are many advantages that would put the market place at ease.

    1. Fuel. Readly available all over the world. We are all firmilier with this processes and supply chains already established. Alternative fuels can also be used. In Brazil we commonly use natural gas but the aftermarket fit can be expensive and is has a bulky gas storage system

    2. Recharge time. A few minuites at the pumps , the same.

    3. Extra MPG. Great selling point. Save money as a consumer but also increase profits for oil companies and government tax revenue. With such an increase in range consumers would not mind paying three to five times the current cost for petrol. This would be a win win win situation.

    4. Upgrade to vehicles. The unit would be small enough and compatible with most cars on the road today. A convertion kit could be installed. In Brazil today Natural gas is commonly used because of the cost of refill. A whole industry has grown around this as the car maunufacturers only make petrol cars . The cars are converted after market. The same could be developed for a whole new power unit.

    5. Car manufacters .Car manufacters could incorperate this power unit into current designs very quickly as the space is the same and Fuel the same .

    6. Enviroment. Massive reduction in emmissions.

    Many things worry me about the current path. Battery powered vehicles are a disaster waiting to happen. The disposal of old batteries will be an enviromental nightmare for generations to come.
    The secound is that the electrical companies will not be able to cope. Millions of people plugging in their cars for the night. They already complain when there is a break on tv program and every body reaches to make a tea or coffee.
    How many times have you heard someone complain that there cell phone is low in power or died. So just imagine that with cars. The emergancy services would have to provide a new service for those people.
    The last , maybe contraversal , point is that we would be giving a lot of political power to the electric compainies as we gave to the oil compainies in the past. We need fuel that is competative and customers can choose not a monopoly.

    Your thoughts on the above would be appreciated.

    That would be a home made Hybrid since that's about what they do. Depending on how it works it could be a series Hybrid like the Chevy Bolt. It basically runs on battery with the gas motor coming on after it's low and recharging itself. We also found it drives the wheels with the gas motor too but it's very similar. The BWM i3 is the same basic idea.

    With the amazing batteries we now have it's twice the cost and half the efficiency running both a fuel and electric. Most small motors are very inefficient, noisy and polluting. What a waste of time and energy. IMO.

    You can do it in a fuel cell car with an onboard fuel reformer to generate hydrogen that powers the fuel cell.

    Highly inefficient as compared to a BEV, of course.

    That's much too optimistic. BEVs are perhaps 3.5 x as efficient as gasmobiles, so if the fuel cell+reformer car could achieve that level of energy efficiency, then perhaps people wouldn't mind paying 3.5 x as much for gas. But they're not anywhere near that efficient.

    According to the article linked below, a BEV is ~77% efficient at using energy stored onboard to power the car, whereas the FCEV is only ~42% efficient. Plus, the fuel reformer would make the overall efficiency even lower.

    Still, the vehicle should be considerably more energy efficient than a normal gasmobile, and that's nothing to sneeze at!

    From Green Car Reports: "Electric cars win on energy efficiency vs hydrogen, gasoline, diesel: analysis"

    This entire section reads like you copied it from an EV-hater's website. Please educate yourself on the realities of the subject. A good place to start is with the humorously titled "The EV-Hater's Guide to Hating Electric Cars".

    Some points:

    1. BEV batteries have low toxicity and can be legally thrown in a landfill. Even if that were not the case, the environmental impact of making one battery pack once, for the life of an EV, is far far less than the impact of making, distributing, and dispensing hundreds or thousands of tanks-full of gasoline for each gasmobile over its lifetime!

    The claims from EV haters on this point are really weird. They write as if we're burning the batteries like gasoline, instead of using them over and over and over for the life of the car!

    2. Electric utilities are already planning for, and building out, new capacity for charging BEVs as needed. That's their job. When a new technology that uses a lot of electricity becomes widely adopted, like central air conditioning in the 1960s, or (probably) BEVs in the 2020s, then the electric utilities have to build more capacity. Anybody who claims this is an impending disaster is trying to sell you a load of bull pucky.

    3. If you drive an EV, then sure, you have to make sure your car has enough "juice" to get where you're going, just like those who drive gasmobiles have to make sure it has enough gas. Driving an EV does currently involve more planning ahead, altho that will improve as EV tech improves. If you can't deal with that, then buy a PHEV so the car can run on gas when it runs out of "juice".

    4. It seems rather silly to worry about giving "political power" to electric utilities. They already sell us electricity; selling us somewhat more isn't going to change much. Electric companies don't make the obscene levels of profits that Big Oil does, so they don't have all that cash sitting around to use to bribe and lobby politicians, like Big Oil does. Plus, with the growing amount of installed solar and wind power, at least some of our future electric supply is going to come from distributed power sources, and therefore somewhat less from the centralized power generation we see today.
