The gold st

of the 21

century is

called

“energy”

Yes. Because imagination is the most

powerful of all engines.

Visionaries are people who can imagine what others can

see only when it is there. For example, an engine that is

powered by “light and air” and that generates thermal

energy and electricity

Inventors blessed with the gift of foresight know that a new

idea follows the laws of evolution:

If it doesn't offer any benefits, it's not going to be around for

very long. If it solves a problem, it will develop further until it

reaches a new level of laws: the laws of the market.

For almost 200 years, generations of inventors have been

constantly improving the Stirling engine. Today, it is ready

for series production and entry into one of the largest

markets of the future.

Because:

With increasing technological progress, the need for

energy is also increasing. Therefore, energy costs will

increase even if electricity prices fall. Energy is the gold of st

the 21 century. Whoever has the means to generate

energy is sitting on a goldmine.

Better looking and

more useful

than your own oil well:®

a SUNMACHINE

Imagine you've got a fascinating

sculpture in your garden that

transfixes the gaze of your visitors.

The large concave mirror automatically traces the path of

the sun. The concentrated energy gets the Stirling engine

up to speed at an output of 2.5 kW and supplies your whole

house with heat, water for domestic use and electricity.

No energy costs, no operating costs and 80,000 hours

without any maintenance whatsoever.

It's not difficult to imagine the good

you'll be doing our environment.

In the summer months and when you're away on holiday,

the Sunmachine is particularly productive, despite the fact

that your house has a lower energy requirement during this

time.

The excess energy is fed into the grid against payment and

is used to top up your energy account held at the public

utility companies.

The solid design is just as robust as it looks. It defies

hurricanes up to force 12 and will still be around to meet the

energy needs of your grandchildren.

Operation is easy:

Switch OFF = Sunmachine is not in operation

Switch ON = Sunmachine produces thermal energy and

electricity

The latest Stirling engine: we've known how it

functions for 200 years. And now we can

guarantee that it does function.

The principle: gas enclosed in a cylinder

expands, contracts, expands again…. and this

moves two pistons that rotate the axle of a

generator.

Temperatures of up to 3000C are attained at the

focal point. No exhaust gases and no energy

costs.

That is x times as high as in the combustion

chamber of an oil-fired boiler. If the sun's rays

are weak, the in-built gas burner switches on

automatically. Thus, the engine ensures a

steady supply of heat, water for domestic use

and electricity. If no heat is required, the whole

plant functions as an air-conditioning system!

An attraction in itself: the calyx technology.

The revolutionary parabolic mirror made of

highly transparent, iron-free solar glass was

developed especially for the Sunmachine. The

calyx consists of eight individual petals which

have a durable silver coating and are sealed to

make them weatherproof. The non-scratch

surface is resistant to hail and able to withstand

desert sandstorms.

Automatic solar tracking

Controlled by an internal clock, the engine's

movements mirror those of a plant following the

sun.

It can replace a modern

condensing boiler with six

solar collectors and a good

photo-voltaic system.

However, it lasts longer

and doesn't cost as much.

thTo celebrate its 100

anniversary, the

Wolfgangshof Estate near

Nuremberg will once again

be opening its doors:

Carefully renovated, it will demonstrate its new lease

of life as solar park, proving ground and

demonstration centre for Stirling engines. Visitors are

always welcome since, in parallel to the industrial

use of the historical building, the infrastructure of the

traditional farm estate will be reinstalled. A few

horses, a few highland cattle, goats and geese to

invigorate the scene and exemplify the philosophy:

the meaningful synthesis of tradition and progress

and the symbiotic co-existence of man, animal and

technology in a wonderful and vital world that is well

equipped to face the future.

TCustomers and visitors from

all over Europe can come to

see the pilot project for a

functioning “Noah's Ark” of the st

21 century.

The energy is supplied

exclusively via Sunmachine

power units. All three types are demonstrated in real

use:

SUNMACHINE ® SOLAR

SUNMACHINE ® GAS

SUNMACHINE ® WOOD CHIPS

There's no better way of demonstrating that industry,

agriculture and our own private lives are far from

dependent on harmful forms of energy.

Soon you'll hardly recognise

the estate of the Count of

Faber-Castell:

Not even Jules Verne could

have come up with anything

better.

Even when driven by gas in the cellar, primary energy consumption and energy costs are reduced by half. And pollution of the environment is reduced by 90%!

Now that it can be fuelled with wood, the Stirling engine can also be used effectively in solid-fuel boilers.

Not every property is suitable for displaying a

futuristic object. But every cellar has space for this

particularly noble form of understatement: The ®

SUNMACHINE GAS.

It is operated by natural gas, biogas or

liquid gas and yet offers all the

advantages of Stirling technology:

providing your house with an

economical and environmentally-

friendly supply of heat, water for

domestic use and electricity. The idea

is nothing new. However, the “Stirling

engine in the gas boiler” has only become suitable

for domestic use due to the development of the new ®

FLOX recuperator burner that, at combustion

temperatures of 1000C, delivers the necessary

efficiency and drastically reduces the level of exhaust

pollution by means of flame-less oxidation.

The new wood pellets represent the most

elegant method of heating with wood. They

consist 100% of wood dust compressed

without the use of binding agents and they

have a very high energy density, comparable

with that of oil.

Their ecological values, however, are incomparable:

pellets are a biomass product made from regenerative

raw materials. They burn without producing CO . 2

The exhaust gas has a low particle content and is

smoke-free. The pellets are delivered by tanker and

blown through a hose

into the storage

container. From there, a

fully automated system

feeds them into the

SUNMACHINE where

they are then burned in

a special pellet burner

leaving no residue

whatsoever.

There's no better way

of heating with wood.

A simple calculation for

environmentally-aware house

owners

The inside story for Stirling

technology enthusiasts

When burned, fossil fuels are converted into carbon.

One part carbon (C) combines with two parts oxygen

(O). Your chimney releases three times the weight of

the oil you burn into the atmosphere in the form of

CO . At a consumption level of 4,000 litres of heating 2

oil per year, this makes 12 tonnes of CO !2

The new Stirling engine STA 520-25 runs on normal

nitrogen extracted from the ambient air at a moderate

pressure of 0.6 2.5 Mpa.

The compressed working medium is generated in the

plant itself by a specially developed miniature electric

compressor that operates according to the molecular

separation principle. This solves the problem of gas

loss in engines running on helium.

The Stirling engine is maintenance-free. For the first

time, thanks to a joint development with the University

of Darmstadt, innovative, permanently lubricated roller

bearings with solid lubricant are used. Another

innovation is the dry-running material matings for

pistons, piston rings and cylinder wall; these were

developed in co-operation with the University of ®

Erlangen specifically for use in SUNMACHINE power

units.

Oil has been dead for millions of years. And it's buried

so deep that the toxins concentrated within it cannot

escape “naturally” into the atmosphere.

So why don't we just leave it to rest in peace? Fresh,

living energy comes down to us every day from above.

And helping the environment will bring you financial

rewards:

Owners of Sunmachines save up to

$2,000 a year and this over

decades.

When the Stirling engine was

advertised for the first time, it still

had a srew loose:

Three years before we had solved the technical

problem of helium escaping from the engine's cylinder,

which necessitated further seven-digit development

costs, we were interested in the fundamental reaction

of the market to the engine.

The response to the advertising campaign for the

Stirling engine as reflected in

the two magazines, STERN

and SPIEGEL, was

overwhelming: the

advertisement with the nun

was awarded the title

“favourite advert of the week”

by W & V magazine. The

Lutheran church imposed a

temporary injunction on our

advertising agency, there were numerous enquiries

from the Ministry for the Environment and some 1500

communications relating to each of the 12

advertisements. Thousands encouraged us to

continue and many asked for an option on the first

series-produced engines as the adverts had made no

secret of the fact that the engine was still at the

development stage.

For us, this test campaign was just one more

proof of the incredibly good prospects for the

SUNMACHINE.
