Well for starters I never said RUN an engine off of it. I said use less gas. Second, it's been ten years since I took Chemlab 101, but adding something to the water is not only for impatience, it's for chemical efficiency. Tap water is not even a question due to all the imperfections in it (heavy metals in the water make your electrodes corrode faster). I'd say distilled water with Sulfuric Acid would be the way to go.Blue Shift wrote: You'll never make enough H2/O2 to fuel even the smallest engine. Plus where's the energy coming from? Electrolysis sucks for efficiency. It also sucks to make work correctly due to nasty issues with electrode corrosion. I once made enough hydrogen/oxygen mix to fuel a tiny torch for a 10 or 15 seconds - after 15 minutes of pumping 12V though several square feet of electrode area, separated by a couple thicknesses of paper towel (they were oxidized to uselessness afterwards)...Try hooking your car battery charger to two electrodes of reasonable size, and dropping them into water. If you're really impatient, add something to increase the conductivity of the water. You'll probably give up on the idea. With tap water, you need massive amounts of electrode surface area.
With noble metal plated electrodes, you could possibly sandwitch a porous material and the two electrodes, and roll it up to make a reasonably sized cell, and feed it water with like, sodium hydroxide or something to bring the conductivity waaaay up so you can flow enough current to make a decent amount of output. It'll output mixed O2/H2 gas at a stoich mix.
Yes, suck for efficiency if you're running the gas engine constantly. However, if you're using it as a daily driver, the idea is that the gas engine is basically a backup (range extender) for the batteries. For your commute to work and back you'll be running primarily on batteries, since it's a plug in hybrid, and in theory you could drive for weeks without the gas engine starting up. In that sense, it's very efficient, as the power plantThe Dark Side of Will wrote:The Volt is a series hybrid, right? The engine just charges the battery?

I understand the concept, but I don't think that a parallel hybrid would be much more difficult to execute and not have any of the characteristics you mention, as long as it was imagined correctly to begin with.Nashco wrote:Yes, suck for efficiency ...The Dark Side of Will wrote:The Volt is a series hybrid, right?

it is - the cost to convert a prius so it can be plugged in is 8000$ according to my friend who has one and has looked into it.The Dark Side of Will wrote:I understand the concept, but I don't think that a parallel hybrid would be much more difficult to execute and not have any of the characteristics you mention, as long as it was imagined correctly to begin with.Nashco wrote:Yes, suck for efficiency ...The Dark Side of Will wrote:The Volt is a series hybrid, right?

After all, there's nothing preventing a parallel hybrid from running a big motor to accelerate the car and get it up hills, along with a tiny engine to push it down the highway straight and level.
