E-POD ED Diesel vs Electric Propulsion

Kevin is at it again. Talking about the differences between diesel and electric propulsion. There are pros and conns of each, but of course we believe that the electric is far better.

And just for the record. I was working in my dad's shop taking outboard motors apart at the age of 12! I've never been far from a wrench. I've had my entire body covered in diesel filth. (Batteries can be recycled)

I've worked in quality control and believe me, I know SAE Standards and I KNOW that they can be manipulated.

Again, I'm NOT arguing that there is no place for a petrol motor, we just need to realize the benefits of electric power.

Folks, I'm NOT saying here that an electric motor is the answer to everything motive!

If you take a look, I'm referring to this application for displacement hull boats.

"a lot of issues"? really? You listed 4 things, 1 of which I would take issue of with in regard to a marine application. There isn't much vibration on an electric boat doing 7 knots.

As for horse power, let's look at an extreme.

Take for instance a locomotive. I wonder why they use an electric motor to drive the wheels.

Instead of just attaching that big diesel thru a traditional transmission.

As for the comment about a 300 hp needing too many batteries. That's a battery problem and NOT a motor problem. True! We need to find a way to store energy that is lighter and smaller, but don't blame the motor. There was a time when a 300 hp diesel motor would have never fit into a 25' boat!

By the way, the Queen Marry 2 uses ... yes ... Electric motors.

@EETechs Part 2. Also when comes to economics, electric motors greatly outnumber combustion engines. Just think about the motors in your car like the starter motor, fan, blower, window, seat, ABS braking, throttle by wire, idle air control, EGR valve, etc. Also every manufacturing plant I have been to have every machine and conveyor belts ran by electric motors. I don't see little Briggs or Honda engines or diesels running the equipment. So combustion engines have a small market share.

@ben5017 This is not even a response to my point I made. You have totally ignored to provide an answer to what I said, but instead you are talking about hybrids and electric cars. Who cares about hybrid cars or electric cars? This is about your false claim assuming that all electric motors have brushes and therefore are less reliable which shows your lack of electric motor knowledge, else you would know about the AC induction motor which is brushless and can last 25 years or more. cont...

@EETechs Appearently, you seem to be a total idiot when it comes to economics ... hybird cars do nothing but milk the taxpayers out of grant money and R&D tax breaks that screw our country! The academics hate the idea that a 1982 VW diesel rabbit averages better economy and less when it comes to repair!

The electric cars do what those who mooch off the govt want most, the break often, the require expensive maintenance, and they have failed to produce a product that can equal a 29 year old VW!

@ben5017 Apparently, you seem to be a moron when it comes to electric motors. Specifically you do not know that there are different TYPES of electric motors. AC induction motors for example to do not have the carbon build up problem because they do not have brushes you retard. Also explain to me why in every industrial job I worked at all I see is 3-phase ac induction motors and not your gay ass Briggs or Honda engines running the equipment? Deal with it pal. Electric motors outnumber gas 1000:1

I have a 30 Cabin Cruiser, I want to power her with an electric motor. I realize I won't have the same power I have with it's current 5.7 300 plus HP Mercruiser. But I know it can be done. Thus I am interested in how I can achieve this goal? Note: using solar and wind to recharge and shore power if needed, would a 20-50 HP electric motor do the trick? Battery weight and run time concerns could be resolved. Who makes such an electric motor? If no one does, then lets make one! Contact me! Thanks

8 hp at the shaft!!! no! 20 hp.. 1 hp for your 100 amp alternator. .5 for your seawater pump and 15% for your gearbox.. * hp is just silly

[ben5017]

A 25 hp Electric motor has a lot of issues as well ... Carbon buildup, vibration damage,to bearings, corrotion damage, battery get damaged from vibration.

Basically einstien, I see that you don't know whit about reality.

What about your battery polution?

Toyota Hybrid gets 46mpg and the New jetta TDI gets 58mpg ... Have your fingers ever touched anything mechanical other than a book?
