Could We Run Modern Society on Human Power Alone?
Unlike solar and wind energy, human power is always available, no matter the season or time of day.
Human power
Interesting possibilities arise when you combine old technology with new knowledge and new materials, or when you apply old concepts and traditional knowledge to modern technology.
High-tech has become the idol of our society, but technological progress is—more often than not—aimed at solving problems caused by earlier technical inventions.
There is a lot of potential in past and often forgotten knowledge and technologies when it comes to designing a sustainable society.

Could we rethink and redesign office equipment, combining the best of mechanical and digital devices?
Modular Cargo Cycles
Modular cargo cycles are cheap to build and easy to customize.
Electric Velomobiles: as Fast and Comfortable as Automobiles, but 80 times more Efficient
About a quarter of the existent wind turbines would suffice to power as many electric velomobiles as there are people.
Electric Velomobiles: as Fast and Comfortable as Automobiles, but 80 times more Efficient (Part Two)
A car with a top speed of 270 km/h can be driven anywhere on Earth, while an electric velomobile with an electric assistance of up to 50 km/h is illegal is most countries.
Cargo Cyclists Replace Truck Drivers on European City Streets
A cargo cycle is at least as fast as a delivery van in the city - and much cheaper to use.
