The clap skate

It must be possible to go faster thought late movement scientist GerritJan van Ingen Schenau in 1980, and he sketched a hinged skate. His colleague Jos de Koning obtained support from STW, made a test model and started to test it. The rest is history.

An open solar telescope

A telescope to observe the sun should preferably be completely open so that no image-distorting air turbulence can develop in the telescope. A STW project has resulted in a tent construction that is open during good weather and easily closed during bad weather.

Switchable windows that save energy

Window glass that can be switched between three sun-reflecting states and in each state obtains energy from sunlight for its own electrical operation. That is the outcome of a STW project, which is now the product of a new company.

Metal fatigue in steel bridges

Steel bridges develop metal fatigue faster than expected. STW research has yielded a method to predict the state and lifespan of a bridge. It has also yielded new types of bridge deck.

Operational processes optimised with process mining

A technique called process mining uses software that models and analyses organisational processes to help improve companies. A STW project helped lay the foundation for a software package that is now commercially available.

WEDACS: using wasted inlet air of car engines

Replace the standard gas valve in the air inlet of a car engine with a rotating valve (a turbine) and you can use the inlet air to generate electrical energy, cool the air in the car and increase the performance of the engine. This increases the energy efficiency and comfort of the car.

CyclOx: diesel from plant waste prevents emission of nitrogen oxides and soot

CyclOx is a new diesel fuel that can be used in each type of diesel engine. It reduces the emission of nitrogen oxides and soot and in the future it can even be produced from plant waste. With the support of an STW Valorisation Grant the inventors of the fuel are developing it for commercialisation.

PFAMEN: new nozzle combusts diesel better

Increasing the number of holes in the nozzle through which diesel is sprayed into the engine cylinder makes the diesel spray finer. And that improves the diesel combustion. A simple yet brilliant idea that also works.

Hearing with your glasses

In the past hearing aids suffered from the problem that they amplified the sound from all directions, which made it almost impossible to follow a conversation in noisy surroundings. An idea to insert directional microphones into the arms of a pair glasses eventually resulted in hearing glasses that are now marketed as a commercial product.

Multilayer mirrors in the chip industry

At the heart of the latest generation of ASML’s lithography machines for producing microelectronic chips is a multilayer mirror that once started life as a STW project.
