Epic - Electric Hybrid Boat

[zapada]

I think its going to happen. Sooner than later we are going to see electric powered Nautiques. I don't think it's as important to be the first boat company to do it as it will be to have the most capable system. In my opinion, Nautique should partner with someone like Tesla, BMW, or Audi and really do this right. Just thinking about it gets me excited. In all honesty, even if the boat ran 4 hrs. on a charge, that's probably plenty for most (assuming rechardge time is 1hr or so).

Does anyone know how electric motors and drives are cooled? I'm wondering if an electric motor would change the entire dynamic of the boat. The mechanics for a boat seems to be a lot less complicated than for an automobile.

Perhaps we're all dreaming here and there is some big obsticle that is preventing this from becoming reality.

nothing is impossible, only improbable. the idea of a gas/electric driven boat is doable. once battery technology gets just a little bit better. I think the most important thing would to be able to get back to the dock/ramp if all the batteries died, res. fuel basically.

I think this would be the same way I got back one day last summer when I ran out of gas. Don't recommend it btw. :-) I would think a combination of low-power warning and perhaps a backup battery that requires turning a switch (there's something psychologically more imminent seeming about turning a switch than hearing a warning beep).

Also last time I check the US navy uses gas turbines aka jet engines to power genartors to power electric drive motors, now they do use steam to launch planes on the carries, but steam hasn't been used for propulsion for some time now. .

Sorry, all nuclear powered ships/boats use steam to drive turbines to generate propulsion, and all US subs are nuclear powered and most of the aircraft carriers are nuclear powered, which also generates steam for launching planes.

I agree, if it is not nuclear powered, then it uses a gas turbine.

Yes, electric propulsion is quieter, but it is only normal operation for a diesel boat.

well if you want to do it right then you sure as **** don't want those clowns designing it for you, I would suggest you use the same people Toyoata, Honda and Ford bought their technology from

50/50 antifreeze/water cooled stators via an external water jacket. The rotor usually doesn't need cooled unless the motor is over 100Kw the good ones have interal oil passages in the lamination stack and rotor shaft tied into the transmission's fluid system, other less efficient motors use an oil spray on the end rings of the rotor.

you need to do a little more research

The Ticonderoga class also brings a multi-warfare capability to the Fleet which significantly strengthens Battle Group operation effectiveness, defense, and survivability. The cruisers are equipped with Tomahawk ASM/LAM giving them additional long range strike mission capability. The addition of Tomahawk ASM/LAM in the CG-47 class has vastly complicated unit target planning for any potential enemy and returned an offensive strike role to the surface forces that seemed to have been lost to air power at Pearl Harbor. Two five-inch gun mounts are used against threatening ships and boats, low-flying aircraft, or to bombard shore targets. In addition, the ships carry a strong Anti-Submarine Warfare Suite and the Navy's latest Electronic Warfare Suite is also aboard. The cruisers have the most advanced underwater surveillance system available today. The Anti-Submarine Warfare (ASW) equipment consists of a hull-mounted SONAR, an Acoustic Array SONAR which is towed like a tail behind the ship, and a helicopter that can locate ships or submarines over 100 miles away.

The "Tico" cruisers, using the SPRUANCE Class hull, measure 567 feet from bow to stern. Their beam is 55 feet, and displacement is 9,600 tons. Four powerful gas turbine engines propel the ships to speeds greater than 30 knots, and two controllable-reversible pitch propellers assist in rapid acceleration and maneuverability.

it would be nice to see effective alternatively powered military land vehicles(hummers, strikers, etc) to cut the cost of war down. i mean i've seen volkswagons that run on people's composted poop. back to the thread, sooner or later there will be a new drive system but who know's when an efficient one will come around.

A person I used to work with was on an aircraft carrier during the Vietnam war. He told me that one time they got orders to get over to the other side of the Pacific Ocean "as soon as is possible".
He said he was up on the bridge, and the speedometer, that was calibrated in knots per hour, and went up to 55 knots, was pegged.

How does that have anything to do with nuclear powered carriers and subs using steam to drive turbines for propulsion? All US subs and new carriers are nuclear powered.

You should do a little more research.

point is your spreading mis-information

carrier's are the only application of nuclear powered ships where the reactor drives a steam turbine, there is only a single reactor on the subs, and they don't drive steam turbines bit noisy easy to detect duh smart move to do that,

surface war ships are mostly gas turbines accross the board slick, get your information correct. It would be stupid for our government to pay for me to be doing the work that I do for them daily considering my company doesn't produce steam turbine, but does produce gas turbines for land, sea and air millitary applications, don't forget the M1-A1 is a gas turbine as well.

This game is fun.

I'm pretty sure I've logged more miles under water than you have on top, but then you have done your research.

So, back on topic. Perhaps CC can hire this guy (http://www.gamepolitics.com/2008/01/...i-pays-a-visit) to design the reactor. The question then will be if direct steam driven or electric driven will be the better way to go. I think I'd vote for electric since that would allow easier custom power curves for various sports and electricity is needed for other stuff anyway and assuming he can design a reactor that doesn't need refueling for 15 - 20 or more years, why not eliminate batteries altogether.
