On dim days, batteries can charge the condenser in a few seconds (2 x AAA cells, not included).
Powered by the condenser, the space vehicles become little racers. The solar module of the ISS
station can also power all models.
- A space station and 6 different space vehicles, which can successively be assembled and powered by
solar energy or the condenser. - The condenser is an energy storage medium with little internal resistance.
It can be recharged in less than a minute to provide power for the next 2 to 3 minutes.

Construction Kit AirCar
€37.99*
For years, many experienced engineers have tried to introduce an air-pressure car to market. They are convinced
that such a car would practically have zero emissions. Now, the first commercial air-pressure car available as a
miniaturized kit gives a glimpse of tomorrows technology. Air as "fuel" is available 24/7, it never runs out and is free of charge!
This car has a top speed of 15 kph with a max. range of 50 meters. It takes approx. one minute to "refuel" the car. To do this,
air is pumped into the top PET bottle. A gauge shows the current pressure. Via the red tubes, air streams to the pistons and
powers them. They in turn drive the gear of the rear axle shaft - the car moves. This power unit is a first stage of what future
manufacturers will install in taxis, small vans and buses.
Will your children become tomorrow's engineers?
