HOW TO DESIGN A SAILING SHIP FOR THE 21ST CENTURY? It is surprisingly difficult to build a carbon neutral sailing ship. This is even more the case today, because our standards for safety, health, hygiene, comfort, and convenience have changed profoundly since the Age of Sail. On board the ship `Garthsnaid' at sea. A view from high up in the rigging. Image by Allan C. Green, circa 1920. The sailing ship is a textbook example of sustainability.

Wood stoves can provide a household with thermal energy for cooking and for space and water heating. Wood stoves equipped with thermoelectric generators also produce electricity, which can be more sustainable, more reliable and less costly than power from solar panels. Illustration: Diego Marmolejo.

If the electricity for a vertical farm is supplied by solar panels, the energy production takes up at least as much space as the vertical farm saves. Urban agriculture in vertical, indoor “farms” is on the rise. Electric lights allow the crops to be grown in layers above each otheryear-round.
REINVENTING THE SMALL WIND TURBINE Many commercially available small wind turbines with plastic blades and steel towers are infamous for their low reliability, high embodied energy, and limited power output. Building them out of wood can address these issues. Because of their aesthetic appeal, and thanks to the ability to produce them locally, small wooden wind turbines can also improve the public acceptance of wind power.

Wood stoves can provide a household with thermal energy for cooking and for space and water heating. Wood stoves equipped with thermoelectric generators also produce electricity, which can be more sustainable, more reliable and less costly than power from solar panels. Illustration: Diego Marmolejo.

Illustration: Rona Binay for Low-tech Magazine. Given the right conditions, a mechanical windmill with an oversized brake system is a cheap, effective, and sustainable heatingsystem.
REINVENTING THE SMALL WIND TURBINE Many commercially available small wind turbines with plastic blades and steel towers are infamous for their low reliability, high embodied energy, and limited power output. Building them out of wood can address these issues. Because of their aesthetic appeal, and thanks to the ability to produce them locally, small wooden wind turbines can also improve the public acceptance of wind power. WOOD GAS VEHICLES: FIREWOOD IN THE FUEL TANK During the Second World War, almost every motorised vehicle in continental Europe was converted to use firewood.
