Macro-engineering involves the large-scale modification and manipulation of natural systems for the benefit of mankind. The primary goals of some Earth-based macroprojects described in this book are power production, land reclamation, food production, climate change, water, transport and coastal protection. Other Earth or space projects considered here have a more futuristic ring, but our present-day technical skill makes their realization possible.

Earth-based macroprojects usually combine different aspects and aims. They have a major impact on the ecology of a region and the...

Jak malý může být slon? Záleží na tom, jak velkou máte fantazii. Není slon jako slon: indický je menší, africký má větší uši… a ten zahradní má zaručeně nejdelší chobot! Malý slon Pomelon se sice vejde pod pampeliškový lupen, ale chobot má tak dlouhý, že si ho při tanci často přišlápne. K čemu takové nosisko, když všude jen překáží? Ke spoustě věcí! Přesvědčte se o tom s Pomelonem! Je zkrátka prima být přesně takový, jaký slon (nebo člověk) je. A mít z toho radost. Pomelon se stane kamarádem dětí od tří let, které se s ním...

The Earth has limited material and energy resources while these resources in space are virtually unlimited. Further development of humanity will require going beyond our planet and exploring of extraterrestrial resources and sources of unlimited power.

Thus far, all missions to asteroids have been motivated by scientific exploration. However, given recent advancements in various space technologies, mining asteroids for resources is becoming ever more feasible. A significant portion of asteroids value is derived from their location; the required resources do not need to be...

Solar radiation data is important for a wide range of applications, e.g. in engineering, agriculture, health sector, and in many fields of the natural sciences. A few examples showing the diversity of applications may include: architecture and building design, e.g. air conditioning and cooling systems; solar heating system design and use; solar power generation; evaporation and irrigation; calculation of water requirements for crops; monitoring plant growth and disease control; skin cancer research.
