ya resistor will do the job but i wonder how do we calculate the ampere once its down to 2v .... how much ampere would the 2v able to take?
after much read up from some pdf files i download off waterpoweredcar.com,
its best to have 7 cell (a pair of + - make one cell) to benefit from the full 14v (generated by most car alternator).
So, to make it abit more simple for noobies like me (and some of us here), i think we should start building one cell first and move on from there........ as many stuff we need to take into consideration such as the following....(quesstion i might need clarification if any one knows the answer..)
1. Under bonnet space and location of the system.(eg.away from heat?)
2. Do we need a bubbler? (a safety and filteration system).
3. IF yes, back to question 1.
4. Where to get the one way valve (to prevent water flowing into the engine)?
5. As i know we do need fuses and relay, based on a one cell design, how much amp of fuse should we use? (i think we have to run it thru an amp meter to check the value if i am not mistaken)
6. how large would the plate be ? bigger would take up higher amp draw from the battery/alternator?
i think thats some little question i have for now...
