Considering this engine for my next boat...

Saw this on eBay and though it would be perfect for my 34 footer. Fuel consumption isn't bad at 440 Kg/hr, and the price is right!

...mate, go for it.....at least it would be something to tell the grandkids about!

Its a good idea


I actually saw a little boat that had a turbine in it.

It was not this one.

But hey.









Dont forget to Bid on the LUCKY BAG!

what will be the life cycle cost of running this sucker?

More likely she will end up like one of these......



This is the 6,000 Hp Baby Duck from Belgium. She does 0 to 160 km/h in 3 sec. The 4 gasturbine engines are from Russian helicopters.



A drag wagon has to be pulled in this sport. The drag wagon has wheels on the back and a foot on the front. The load on the wagon starts at the back and moves driven by the wheels forward to the foot whilst running. There are gears to regulate in which speed the load moves forward to the drag foot. Max load on the drag wagon is about 24 ton nowadays but that is moving up as the tractors get stronger.



Usualy a run is max 100m. Pulled distance before the wagon stops the tractor is what counts. In case of a full pull it's the time that counts.



But don't bother, this is a girls sport . . .

In Europe there are tractors over 10,000 Hp, max weight for these animals is 4.5 ton.

Here is Baby Duck's website, here the photo and film links. See also Tractor pulling.

Nice to see a picture of you Angel!
And now you affinity with tractors becomes clear .......

Well, this was my avatar here for a while

But the girl's name is Caroline, she does the electronics and is one of the two drivers.

I consider it as a compliment to be compared to Caroline! Thanks

Cheers,

Like anything there's a time and place for everything.

They can have a thermal efficiency of up to 40% which is much better than gasoline engines.

Given a choice,1100 hp:
-buying,maintaining,and rebuilding every 100-200 hours a supercharged 500-600 Ci V8
-having 2.5 tons of a huge expensive diesel engine ~50 gallons an hour
-having a 400 pound, 1100 hp 5' by 2' diameter turbine and have it last couple thousand hours. About 80 gallons an hour,maintenance consisting of changing the oil and able to burn whatever is flammable.
Have seen good used surplus/rebuilt for $5k...rebuilding is basic.
A friend works on heli turbines...

Love the sound...

That was before tuning and repainting, of course! Caroliiine.........

They do sell a lot of LM2500s

This one is red and has a tuned piston engine. Big pic here

It's the European Maid in 2009 in Wierden in Holland. Driver is OK due to good clothing.



But slightly back to topic . . . .

What about one of these as a genset for heating and juice * in a boat . . ? ?

PS - * and Absorption Chiller Air Conditioning (exhaust heat can be used for a absorption chiller which create cold for air conditioning from heat energy)

Microturbines click for many links in the original article.

Microturbines, also known as: Turbo alternators, MicroTurbine, Turbogenerator.

Microturbines are becoming widespread for distributed power and combined heat and power applications. They are one of the most promising technologies for powering hybrid electric vehicles. They range from hand held units producing less than a kilowatt, to commercial sized systems that produce tens or hundreds of kilowatts. Basic principles of microturbine are based on micro combustion.

Part of their success is due to advances in electronics, which allows unattended operation and interfacing with the commercial power grid. Electronic power switching technology eliminates the need for the generator to be synchronized with the power grid. This allows the generator to be integrated with the turbine shaft, and to double as the starter motor.

Microturbine systems have many advantages over reciprocating engine generators, such as higher power-to-weight ratio, extremely low emissions and few, or just one, moving part. Advantages are that microturbines may be designed with foil bearings and air-cooling operating without lubricating oil, coolants or other hazardous materials. Microturbines also have a further advantage of having the majority of the waste heat contained in the relatively high temperature exhaust making it simpler to capture, whereas the waste heat of reciprocating engines is split between its exhaust and cooling system. However, reciprocating engine generators are quicker to respond to changes in output power requirement and are usually slightly more efficient, although the efficiency of microturbines is increasing. Microturbines also lose more efficiency at low power levels than reciprocating engines. When used in vehicles the static efficiency drawback is negated by the superior power-to-weight ratio - the vehicle does not have to move a heavy engine and transmission.

They accept most commercial fuels, such as gasoline, natural gas, propane, diesel, and kerosene as well as renewable fuels such as E85, biodiesel and biogas.

Microturbine designs usually consist of a single stage radial compressor, a single stage radial turbine and a recuperator. Recuperators are difficult to design and manufacture because they operate under high pressure and temperature differentials. Exhaust heat can be used for water heating, space heating, drying processes or absorption chillers, which create cold for air conditioning from heat energy instead of electric energy.

Typical microturbine efficiencies are 25 to 35%. When in a combined heat and power cogeneration system, efficiencies of greater than 80% are commonly achieved.

MIT started its millimeter size turbine engine project in the middle of the 1990s when Professor of Aeronautics and Astronautics Alan H. Epstein considered the possibility of creating a personal turbine which will be able to meet all the demands of a modern person's electrical needs, just like a large turbine can meet the electricity demands of a small city. Problems have occurred with heat dissipation and high-speed bearing in these new microturbines. Moreover, their expected efficiency is very low 5-6%. According to Professor Epstein current commercial Li-ion rechargeable batteries deliver about 120-150 Wh/kg. MIT's millimeter size turbine will deliver 500-700 Wh/kg in the near term, rising to 1200-1500 Wh/kg in the longer term.

Wow Angélique,

thats what I call a proper cigarette lighter!

Yepp, the Micro Turbines are a promising solution. Unfortunately the industry is not providing too many reliable and affordable items as far as I am aware.

Jaguar is looking at micro turbines as back up/get home power in electric cars.

The largest problem is the accurate micro machining of the compressor blades to get efficiencies up,guy has been working on the problem for 15 years.
