Re: The $100,000 80hp outboard

This new green technology stuff is amazing. The next thing you know, we'll be using wind to power our boats.

The sad part is how very many people out there truly believe that this would work.

Show me one viable electric airplane, viable means able to actually go somewhere, not a glider with an electric motor.
If viable means 200 kt cruise in your 6 seat airborne SUV, then your right, we aren't there yet with current battery energy density. But if you fly just for the pleasure of flying and not using it as a transportation tool, it is here today.

I started in hang gliders, then U/L and GA. Flying is more pure without the noise, smell and vibration of an ICE. For an U/L powered by a 2 stroke Rotax engine, operating costs with TBO and 100LL is about $30 per hour, cheap by GA standards. If the same U/L is powered by an electric motor and Lipo batteries, upfront costs are close to the same but hourly costs (including future battery replacement) is about $5 per hour at $0.10 per kWh. Much less in the PNW.

At 300 hours per year of pleasure flying

Gas engine $9000 per year.

Electric $1500 per year.

Here is Mark Beierle's Gull 2000 U/L.



On the electric front we have crossed the 200 mph level.

Of course it works. I know because I have one.

It's in my garage sitting right next to my 200 mile per gallon carburetor and my magnetic fuel enhancer.

Re: The $100,000 80hp outboard

A sailboat with a loud diesel engine makes no sense, to me.
A loud airplane with a quiet motor doesn't either. It is nice not to burn hydrocarbons,
but the case for heavy electric airplanes just isn't compelling.
(Or a $100k slow 80hp for a powerboat!)
Whereas an quiet electric slow boat it sure does.

Re: The $100,000 80hp outboard

Jack, the 80 hp ob is $20K and a single battery is $16.5K. Regardless though I agree with you on a slow boat electric powered. As you know the Atlantic was crossed at a stately 5.5 kt average on just 10 kW of solar and batteries powering a catamaran.
