i guess i didn't make it very clear......ok i understand that the resistence would drain the battery and the energy created would not be enough to off set the drain in the battery. by air damb i mean the same as a hood scoop...dont know how to explain it much more than that like most 'electic cars' they run on fuel untill a certain point....what if the energy from the blades was only harnessed while fuel was the main contributor to the over all movement of the vehicle.....and when it's being run off the battery, a small sheild would come up infront of the air damb eliminating the air resistence,not slowing it down at all now if the vehicle was run 10 miles reaching top speeds of 50 using mainly fuel, then merged on to the highway for x amount of miles going 70.... the battery would have been charged enough to sustain 70mph for x miles now the question is, is x miles worth the added resistence while the vehicle is running off of fuel? sticking a retractable windmill so when you park the vehicle i find to be comical this has been something i've been pondering for a couple weeks, and i'm not very serous, just thought i would bring it up to make some viewers rethink the already thought of. if it were up to me....the heat from the exhaust would be captured to run a form of boiler....the roof would be solar panels, and the actual aerodynamics of non-commercial vehicles would be regulated and be enforced... but none of this would matter as long as people still want all those horses under the hood and dont mind paying for it......you can't regulate freedom i guess/or can you?

i'm yet to research this idea.... having said that, if a air damb was made and inside of it was a mini wind mill and the power of which was directed to the alternator that in return charged the batteries that the vehicle runs on...... now i understand that enough energy probably would not be produced to run the vehicle on it's own, but i would like to think that enough would be created to make the batteries charge to stay higher, longer. questions i have...will research on my own....but if you have the answer please share... what is the ratio between the minimum air speed on the blades, the blades surface area and it's out put in torque? what is the ratio between torque and a generators ability to create energy? something to ponder: is the energy out put enough to make up for the drag of the air damb......i'd like to think that the drag wouldn't be much at all(might be misinformed) understand with a smaller blade, the less you'll get from it..if the air damb was the width of the vehicle and sat on the roof-having the fan blades all in a row across the roof....so i'm sure that driving 60+mph (opposed to 15mph for the big wind mills); this i believe would imply that the surface area of fan blades is 1/4 the area of the big fancy ones in the fields around the world....

hmmm... where to begin, first off the "bladder" idea is just foolish and wasteful....so many things wrong i'm not even going to get into it.... the energy from the lift of the bladder can only be collected once, and ends as soon as it reaches the top??? if the energy of buoyancy can be captured again and again, the only thing restricting the possibility of capturing the energy is the depth/length* of when it starts and the mass of the buoyant gas. this being said, the efficency is all relative to the lengths* you are willing to go....excuse the pun, and the minimum mass of gas that in return gives you a measurable and obtainable amount of energy. Now here's the best part..... the obtainable amount of energy does not need to be very much at all.....why you might ask!?......well that just means it's going to take that much more energy to get there.......but it's not very much?.....well remember i said it's realitive to the length, because this length gives you more opportunities to harness this energy..... next.... the gas transfer/relay/cycle is to be powered by not electricity(maybe very little for computing, but nothing big) it shall be driven by whatelse....gravity this is a whole nother story, and spurs a whole new conversation....just think weight of under water, and weight above surface, use the weight of water above surface to off set the buoyancy of the gas..... i have most of the math worked out, there is no question i have it figured it, now it's just fine tuning the thing for the best return......which realy only matters how big i want to make it i would like to maybe get a little help.....maybe......certainly need some money to invest, i've made cheap protos but they are not nearly large enough(i'm talking small) and materials and construction was a little crude, again due to not having enough money to invest in it i hope this opens your eyes and maybe you can start to think out side the box
