Let's see some pictures of this thing we don't care if it's perfected yet or not. We like build thread's and pictures.

I was talking to Alan Kroeper with Revolt Hydrosport! Sorry I guess I should have mentioned that.
Kawi550 I am sure everyone would like to see what you can come up with also thank's

The first development ski was not picture worthy. There were a lot of things we did just for testing that were not representative of our intent (sensors, data logging, duct tape, bailing wire, vise grips), so we decided early on that the first one would be kept mostly to ourselves.
The SX-R build will be done in the open, with pictures and stuff on the website. Probably around the end of January. (I don't want the build to be too far ahead of the availability of actual parts in March/April)

I am beyond stoke! I remember last year there was a tread about Electric Jet skis and most just laughed about it. I am really happy to see that there is actually people working on it....and a few peeps interested on what is going to come out of it.
Yes they are. The main reason why 2 stroke are outlawed is because they contaminate. This is based on the EnviroNAZIS so called "research". I am also aware of the 200 yards zone in the surf, however I am not going to ride next to people, I will look for the most desolated beach to launch and do my thing. Rangers don't care so much in desolated areas and my main concern is to be stop based on the "polution" crap. As a matter of fact I would not be surprised if those same rangers will be glad to see a "Green" Jet ski.....
Moving? HELL YEAH!
Trust me I am looking for work in the SLO area.....I already convinced my GF so I am half way there....LOL!

what sucks is even if you get it to where it will "work" , it will run for about 15 20 minutes, then take two or three days to recharge.
if you come up with some kind of compound that will hold and output more voltage, and not take as long to recharge, you're getting really close to running into building a damned nuclear powered ski...LOL
I don't want a nuclear powered ski...lol, it's not worth losing my hair and half my life over.

Everything is picture worthey! You are inventing you are doing something that has never been done before! That's exciting and I completely understand not wanting to share the secret's no problem there good luck. You could at least show us something ?

was talking about the hull being sealed up so if wont sink. duh on the water cooling. and lead to a possable failer and sinking and electricution!!! IT WILL NEVER BE MASSED PRODUCED!!!!

so for the motor.. whats the theory a straight up high torque dc motor? or a dc servo drive... slightly more complex but the prgrammable features would be amazing

from what i can gather he used a brushless D/C motor. then lithium ION cells. i think lithium polymer is better but more expensive..

i work for a part of bosch .. we sell automation products.. but i know in the main bosch powertools division they just did a colaboration with samsung .. they released the 36 litium ion battery and i believe that they are developing the next generation of batteries

We like it or not, electric will be the future... I like it, easier to maintain, and eco friendly... but only if a ski whith that motor will be able to do backys..

ok, question, what are you guys thinking as far as a sealing a cooling system? I was throwing this idea around a few years ago and was in contact with hacker industries to see if we could build a strong enough brushless dc setup. the problem we we're running in to was being able to keep the system sealed enough to where you wouldn't get water intrusion, but at the same time the motor would be able to breathe and not over heat. even though dc motors do not run on air/fuel mixture, they still have to breath or they will burn up.
the other thing is the batteries need to stay at a nominal operating temperature. the lithium batteries can stay too cool or it will slow their discharge rate, and if you're using lithium batteries and they get too hot from not being air-cooled enough, they will explode like a fire bomb. I've been flying electric r/c planes for a long time, and I've had the lead wires build up a resistance from too much heat, back up into the battery and send the little foam plane back to earth on fire and a ball of melted styrofoam goo. that's just from not having enough airflow from the prop vectored through the plane keeping the system cooled.

Wrap a copper coil around the hot stuff and pump lake water through it with the jet pump.

you would need temparature sensors and water control solenoids controlling the flow based on feedback from the cooling sensors. that would work for the batteries, but the motor still needs to breathe or it will toast. you can't just wrap a copper cooling coil around a brushless motor and not give it any air.
