Our passion

We want to inspire and help people to do something about climate change, without compromising in the quality of life. It is all about being creative and making conscious choices. Having the guts to try something new…

We do this by sharing the stories of people and projects that have implemented sustainability in different ways. How have they done this, and what can we learn from them? When it comes to sustainability there is not one good scenario on how to do it. By sharing different optional solutions, we want to help every individual to find new ways that suite for you.

The expedition car

  • The car is made in 2021, and bought in 2022.
  • We take a 50L water tank with us that we fill with self-purified water to drink, cook and shower. 
  • We cook induction.
  • We work with an innovative charging technique; directly DC instead of DC-AC-DC and without a battery in between the solar panels and the car. The result: up to 20% fewer energy losses. This charging technique is built by Venema E-mobility.
  • 60 solar panels of 1m2 each are stored in a frame with 6 drawers. The solar panels are 180Watt each. We will take them out of the car to charge.

Custom 200L rooftop
box for our luggage.

We sleep in this rooftop
tent. It can be set-up in
less than2 minutes and
has beautiful windows,
even a roof window.

Custom solar panels are
installed on the hood, the
rooftop tent and -box.

The car has all-terrain tires,
rims of steel and the ground
is enlarged with 6cm. 

On the front windows a special
foil is added to prevent
radiant heat.

In front of the grill we added
some extra protection to
prevent stones from crashing
in our airconditioning.

Our sustainable experience and experiments

Some experiments we have implemented in our private life:

  • We do not need natural gas at home anymore, by adding solar panels and a heat pump
  • Cooking electric
  • Buying food of the season, of the region, and less meat
  • Buying less packaging with initiatives such as PieterPot
  • Buying products that are close to the expiration date to prevent them from becoming waste
  • Taking a bag with us when we go shopping
  • Making our garden into a home for bees, butterflies, and animals with native plants that belong in our environment
  • Starting 2020 we chose to no longer travel by airplane
  • We collect rainwater, and use this to water the plants, flush the toilet and for the dishwasher and washing machine
  • Driving electric
