Making a hybrid car?

In the early 70s Mother Earth news advertised a kit to make a hybrid car using a 5 horse engine to run an alternator that fed a battery bank which in turn ran an airplane engine starter motor coupled to the transmission shaft. Is that still viable? Or does anybody have that set of plans for sale?

Plantbot hybrid drone

Hello i recently stumbled upon this instructable here. https://www.instructables.com/id/Plant-Host-Drone/ but the guy didn't put a how two. i was wondering if anyone could figure out how to make one and post a step by step. Also i thought that it would be could if you could make it seek out light. like if a shadow goes over it for more than a minute it seeks out the nearest light source but if it cant find one for lets say 5 minutes then it shuts down.

Suggestions for harmonica hybrids

Hey, I just posted my giga-monica instructable and was wondering just what else I could use. To save you the search, I've hollowed out a spot about an inch or so long and just wide enough to house the connector of a usb device into a cheap harmonica. The idea being that you can insert something here to prove to your friends that yes, you don't have a life. So far, i've tried a flash drive, a 'Blues-tooth adaptor' (conceived solely for the name), but cannot think of ANY other devices you could use.. at all. In fact, to be blunt - what tiny usb devices can a computer use? (Picture shows roughly how much room you've got - no specific measurements because I'm looking for generic items, not specific models) Thanks in advance, McDouche

Human Electric Hybrid Vehicle

The HE Human Electric Hybrid Vehicle It looks like an interesting concept car. Although, it might be hard to find somebody who wants to pedal it. I really like the solar panels on top, and how on the downhill, it charges a capacitor for energy.This HE Human Electric Hybrid Vehicle concept uses the power of your muscles as well electricity stored in the batteries. It allows smooth and constant velocity both uphill (with the help of the electric motor), as well as downhill (when the wheel acts as a generator and charges the batteries). The vehicle can turn 360 degrees maintaining stability all the time. Additional power is acquired from photovoltaic placed on top of the vehicle as well as during de-acceleration from regenerative braking. Elderly and handicapped people that are unable to provide enough kinetic energy can also charge the batteries directly from the grid.

Hybrid cars - uphill strategies

I own a hybrid car (Honda Insight 2nd generation - CVT) and I'm happy with the fuel economy (4.3 L/100 Km  --  54,7 MPG),  but I think there is still room for improvement. My house is on top of a hill and when I get home I have to climb steep slopes. The batteries go low and the forced regeneration kicks in. (The car uses the gas engine to recharge the batteries.) When I get home the batteries are almost fully charged. The next trip is, of course, downhill and the high state of charge prevents me from getting the maximum advantage of regenerative braking. (Put in other words: I'm burning gasoline uphill to recharge the batteries that I could charge for free driving downhill...) How could I avoid/reduce forced regeneration? What strategies do you use driving uphill? Thanks

Series Hybrid Motorized Bike

I am designing a system to motorize my bike, but I really don't have enough money for it. I have been thinking I would like to use this engine for quite a while, because it's cheap, light, and OHC. There is a centrifugal clutch for it, but it costs $85, so I've been trying to design a series hybrid system instead. Considering that these motors cost only $6, it seems perfectly feasible to make something cheaper this way, but there are ways I can think of to possibly make it even cheaper. Here comes the technical part: my original design has two of the motors hooked up to the engine at double speed as generators, making 12v. Then there would be two more of these motors traction-driving the rear wheel. The problem with this is that the gear reduction is expensive. My new design has the engine directly driving only one generator, making only 6v so that I would have to have as many as 8 motors driving the wheel (opportunity for AWD?) to pull enough current to get full power out of the engine. Here's the problem: I don't know if the generator will be able to handle that current draw. Considering it would only have to do it for a couple seconds, do you think that one of these motors (working as a generator) could handle 400 amps surge? Other information: this will not see much low-speed operation. Geared to top out at about 25mph, it will probably spend most of it's time going 10-20.

A Hybrid of Coil and Rail gun

So I said i'd throw this up in the comments section on Youtube not too long ago, and I don't like it when something easy and free doesn't happen. This is some ideas and observations that have to do with coil guns (mostly). I'm in the process of finishing up several projects, so my resources are kinda spread out. I should have a prototyped coil gun finished in 2-3 weeks though, so if this doesn't clear things up, hopefully that video will. I should point out, I am a chemist with expertise in biochemistry, not electrical engineering. Basically my idea is to combine a railgun and a coil gun for the expressed purpose of avoiding the pitfalls that a pure coilgun or a pure rail gun have. At present, none of the designs out there would be capable of competing with an actual gun. By mixing the two, i'm hoping to get something that might eventually be capable of doing so. So.. I've included a very poor drawing (I'm not an artist). The barebones circuit is sketched in the lower right hand corner. The gun barrel, which is a piece of aluminum tubing split into two pieces to sever as a rail system, is sketched in the upper left, and again in the middle figure to show how to integrate the coil and rail system. Looking at the circuit design, you can see that this starts off as a very basic capacitor-inductor circuit. The charge is purposefully allowed to trickle through the circuit until the coil reaches saturation and the capacitor(s) are charged. When the trigger is pushed, the inductor side of the circuit has to dump into the rail system to complete the full closed loop. Because of the ferromagnetic material (the brown stuff), the magnetic force persists for a while (that is to say, it has high reluctance). The ferromagnetic material does one other thing that is important here. It forces the middle of the coil to be far off center. The coil is pulling the projectile into the middle of the magnetic field, but that is not necessarily in the center of the winding. Adding ferrite, or other high reluctance material, towards the end of the barrel biases the field towards that end.  At the same time that the coil stops getting current, the rail system become active. This allows a charge to pass through the bullet/projectile, and, even though the majority of the force is going to be caused by the inductive coil, the rail system allows an eddy current to setup in the bullet. This does several things. First the bullet doesn't have to be iron, nickel, or cobalt. With a stray eddy current in the projectile, any conductive material will work. The advantage here is that once the current stops, the non-magnetic material stops being  to the magnetic field, preventing backwards acceleration of the projectile as it exits the barrel.  Second, Rail systems and coil systems are not often used because they are perpendicular to one another, but, this can be used to put spin on the projectile, in a similar manner to rifling in a barrel.  After the projectile is fired, the circuit is open, preventing excessive electrical discharge.  My circuit design is really badly drawn... =T if it needs more explanation please post up questions.

Toyota Will Offer a Plug-In Hybrid by 2010

If you make it, they will come. Or something.CalCars, the California Cars Initiative, has not only been campaigning for plug-in hybrid vehicles, they were the first to build a plug-in Toyota Prius. CalCars longstanding, and really quite simple, thesis is that plug-in hybrids can achieve 100+ MPG using today's technology:We promote plug-in hybrids (PHEVs). PHEVs are like regular hybrids but with larger batteries and the ability to re-charge from a standard outlet (mostly at night). They're the best of both worlds: local travel is electric, and you always have a gas-tank backup. More details here.Toyota seems to have finally received the message, now pledging to offer a plug-in hybrid by 2010: Toyota Will Offer a Plug-In Hybrid by 2010 (NYT). From the article:DETROIT -- The Toyota Motor Corporation, which leads the world's automakers in sales of hybrid-electric vehicles, announced Sunday night that it would build its first plug-in hybrid by 2010.The move puts Toyota in direct competition with General Motors, which has announced plans to sell its own plug-in hybrid vehicle, the Chevrolet Volt, sometime around 2010.Katsuaki Watanabe, the president of Toyota, announced the company's plans at the Detroit auto show as part of a series of environmental steps.Mr. Watanabe said Toyota, best known for its Prius hybrid car, would develop a fleet of plug-in hybrids that run on lithium-ion batteries, instead of the nickel-metal hydride batteries that power the Prius and other Toyota models.Plug-in hybrids differ from the current hybrid vehicles in that they can be recharged externally, from an ordinary power outlet. In a conventional hybrid the battery is recharged from power generated by its wheels.Mr. Watanabe said the lithium-ion fleet would be made available first to Toyota's commercial customers around the world, like government agencies and corporations, including some in the United States. He did not say when they would be available to consumers.Another case of hackers' solutions becoming mainstream? Definitely!

DIY Plug-In Hybrid Pickup Truck

Hi everyone, For a while, I've had this as my "back-burner" project. I'm trying to really get going on it now. It's an Open Source, DIY, Plug-in Diesel/Electric Hybrid Pickup truck. That's really a mouthful, so I'm just calling it the "SuperTruck" project, until I can come up with a better name. The entire concept is that it is a parallel hybrid, which you can charge from the wall, and it has a diesel engine that can run on diesel, bio-diesel, and possibly veggie oil. Either the engine OR forklift motor will be able to propel the vehicle. (Meaning that it will have a dedicated EV mode.) The driver can manually decide to run it on diesel, electric, or both depending on the driving situation. The mechanicals are relatively simple. It uses a manual transmission (rather than a CVT or planetary gearing.) In theory, this will be a project than any advanced grease monkey will be able to duplicate. I'm not much of a car guy, but I have learned quite a bit working on my electric motorcycle, electric car, and experimenting with running my car as a hybrid. Here's a YouTube playlist of what I've got going so far. For the latest on this project, please visit the page for it on my blog: http://300mpg.org/projects/supertruck/ I'll definately need help on this project, so please tell all your friends about it!

SF's Hybrid Buses are Easy to Shut Off

This is an odd one! Apparently, kids have been playing around with the hybrid buses as they roll along -- by turning them off. The off switch is apparently just under a unlocked panel on the side of the bus."When that happens, the drivers can't accelerate, they lose radio contact with dispatchers and the interior lights on the buses go out. The power loss does not affect the brakes."They say that they're working on locking the compartments -- which seems like a good start -- as well as increasing patrol among the areas, as other attacks were common.Chronicle via Gizmondo

New breed/ hybrid sunflower! Market opportunities??

I always have lots of flowers in my allotment garden. Sunflowers, originally from 3 different  seed package varieties 5 years ago, come up spontaneously in spring, the seeds spread by birds. I usually collect the seedlings to put them in some rows, for beauty, wind protection and bird/ bee food. This year a large plant came up with double flowers. I have only ever seen small plants with double flowers. I am collecting all old flower heads and will sow these seeds in a small field next year, weed out all non double sunflower plants, and protect them from being pollinated by other, non double plants.  So next year I might end up with a big bag of seeds for big double sunflowers! So far so good, but then??? I think many people would love to buy a packet of these seeds, but how to go about? Should I change my pseudonym BobS to BobMonsanto?

Hybrid electric vehicals, batteries going serial or parallel

Can I wire 7000 lithium ion battery cells (about 75kwh) in parallel, and then use a lightweight bike engine hooked to a DC generator and connected in series to the batteries to boost voltage? Are there any flows in this design concept, for use in a hybrid race vehicle to increase the longevity of the batteries?I am trying to develop a race track car which is hybrid, thus utilizing electric motors immense torque.We build original race cars with common petrol engines but now I’m seriously thinking of developing a next generation race car. I know batteries don’t last long in high drain situations and thus any race car I sell will need a battery replacement after a race season. I’m sure this will be bad for business. Thus this is why I’m thinking of ideas to prolong the battery life by reducing current drainage. That’s why I want to have an engine generator with its sole purpose is just to boost voltage, and about 20,000ah worth of batteries connected in parallel so I reduce current demand per battery cell to well under 1C. Giving a Tesla p100d as an example I would require about 1200 amps and 400 volts to produce 480kw of power. If wire all 7000 battery cells in parallel to produce the same amount of current then each cell will need to provide about 0.18amps that’s very low to sustain longevity of the batteries. The generator is then connected in series to help boost the system voltage to 400vIn extrem simple terms, (the batteries provide the current, and the engine generator provides the voltage)I hope you understand why I’m looking at it this way. I know it might not be the most efficient way, but is it a practical doable way? Thanks

Floating Dock/Pontoon/Cabin Hybrid. Please Help!? Answered

So i have this idea for a vessel i would like to construct. First, imagine a 10' by 20' floating dock. It floats using steel or plastic drums arranged in a line and possibly attached to make two parallel pontoons. After the "dock" part is constructed, a 10' by 10' cube will be constructed on top, around 3/4 of the way back on the dock. The rest of the space in the front of the cabin will used for a mast and pirate-like (:)) steering assembly managing a rudder or two on the aft. Propulsion can be sorted later and may not even be necessary. I would also like pointers on how and where to construct this and possible costs parameters. I am on a lake, Lake Cushman if you've heard of it, and have little dock space. The lake level will go down and provide an inclined beach where i can begin construction over the winter. The lake level will rise after winter, but it can be completed by then i believe. Assume i have the cabin idea figured out, all i need advice on is the above stated. Thanks! Any advice is much appreciated!

Antarctica-Bound Hybrid-Electric Hummers Visit Pier 9

Drive Around the World, a nonprofit founded in the Bay Area, revealed its latest innovation, a pair of hybrid­-electric Polar Traverse Vehicles, also known as the Zero South PTVs. These two unique vehicles are bound for a history­-making expedition across Antarctica and they came to Pier 9 today to talk about it.  These revolutionary vehicles, designed using Autodesk tools, have undergone an extensive transformation from gas guzzling Hummers to open source, environmentally conscious biofuel hybrid­-electric vehicles outfitted with ice tracks and capable of standing up to the Earth’s harshest environments. Vehicle designers and leading NASA scientists discussed the expedition's logistics and the latest in climate discoveries. From the Zero South team: There is intentional irony in repurposing the Hummer H1, which many view as a contemporary symbol of gross consumer waste and inefficiency. Others view it as a remarkable multipurpose machine capable of extreme on­ and off­-road performance. But no matter which way the audience is ³polarized² by the vehicle, this adventure will appeal to everyone. Zero South Electrical Engineer Brock Winberg

Can Non-Hybrid Cars Get 100+ MPG Today?

  We're not talking about hybrids here; our topic is cars powered by the basic IC-engine that relies on gasoline and not electric motors. Today's gasoline engines are not designed to combust/burn gasoline efficiently. Even with the advent of using high pressure fuel injection techniques that are computer controlled, we still fall short of the mark. Partly because liquid gasoline can't burn, only gasoline vapors burn, and there lies our problem. The same goes for injecting the high pressure droplets of fine-mist liquid gasoline that enters the engine cylinder using our current nozzle ejector technology, it doesn't all burn at the same time! Engine designers assume that these droplets are instantly vaporized by the engine's hot cylinder walls, and then instantly explode/combust when ignited by the sparkplug. Not true, up to 2/3 of the fuel isn't vaporized and doesn't combust until later on in the cycle. The 1/3 that gets almost-instantly vaporized and burns will do so within the several thousandths of a second (Fig-1) it has before the piston moves down its 1/2-stroke (out of today's 4-stroke cycle) completing the engine power-portion of its cycle. This releases power and tremendous heat which indeed vaporizes the remaining ~2/3 of our fuel from its liquid droplet form, but too late. It essentially does so when the power stroke is almost over or the piston is just about ready to move into its up-stroke (2nd stroke of our four stroke cycle) phase. So, because of poor vapo-timing we have 2/3 of our fuel virtually wasted by exploding at near the bottom of the power stroke. This incorrect explosive timing, which happens to most of our fuel, imparts very little energy into the crankshaft because its effective "moment" (a product of explosive force and radial-component distance from crankshaft center) is insignificant by then. Various attempts at adjusting the combustion timing spark hasn't made a significant difference. Even though ~2/3 of the fuel is now exploding and providing a huge force, its small "influence" arm distance is rapidly diminishing to zero, and any huge downward force times near zero arm-length is still zero. Some clarification here, technically thermal-efficiency is not improved, pretty much all of the gasoline gets combusted today. That means the energy of the fuel is almost totally released, but not effectively used. The problem is the timing it takes to convert fuel-injected gasoline droplets into vapor to combust at the correct engine rotational time and extract that expended energy. If you did the math for any size engine rotating at say 3200 RPM, you would find that a 4-stroke engine can only extract that energy from combustion during one of the four strokes. And the time it takes to make that stroke happen is only about 9.4 thousandths of a second or 9.4 milisecs (msecs). Now picture the piston just below TDC, all its valves closed, under pressure and containing all the fuel and air it needs to combust. At this point our deadly cocktail has about half of the 9.4 or about 5 msecs to complete combust after the timed sparkplug ignites it. The half factor exists because the max portion of our power stroke (moment arm) occurs at the mid-stroke of the piston sliding down and turning the crankshaft. If all of our fuel isn't combusted by then, the moment-arm or distance from the piston-center to the crankshaft quickly reduces to zero. Again, only vapors combust within a healthy 2 msecs (Fig-1), while fuel droplets take a relatively long time (>5 msecs) to vaporize before it can combust. Unfortunately nature is stubborn and vaporizes ~2/3 of our injected fuel droplets only during roughly the second half of the power stroke. So this huge amount of energy gets wasted because even though the forces of combustion are huge, its moment arm is rapidly approaching zero. Infinity times zero is still zero! Engine designers/engineers have been plagued by this phenomenon ever since the creation of the 4-stroke gasoline or Otto cycle engine. We need to improve this intermittent combustion/explosion process by combusting all of our injected fuel at the correct timing sequence. This is accomplished by injecting only vaporous fuel which will produce ~3X the power we now get. Another way to state this is, for the same power that we now get from a gasoline engine, if we burned the fuel correctly, we would only need 1/3 the fuel consumption to get 3X the current MPG.
