Solar FarmsSolar FarmsParabolic mirrors focus the sun’s
energy on a small area, generating heat, which can then be converted to electricity. Large scale solar tro ghs like troughs, like these in California, have tremendous commercial energy potential.

Provide energy from fusionProvide energy from fusion
Fusion is the energy of the stars. Enormous heat and gravitational pressure compress the nuclei of certain atoms together to form heavier nuclei.
In the process, a tiny t f i amount of mass is
transformed into energy.
Fusion ReactionFusion ReactionUnder high pressure andat high temperature twoat high temperature twoisotopes of hydrogen,deuterium and tritium,f t th t ffuse together to form ahelium atom and freeneutron. The neutron canbe combined with lithiumto produce more tritium.
There is 300 times more potential energy in a glass of seawater than the equivalent volume of gasoline!Deuterium, or heavy hydrogen, occurs naturally in the ocean and is a key fuel for nuclear fusion reactors.

laser heats the plasma and triggers fusion pulses creating propulsionpropulsion.

Manage the nitrogen cycleManage the nitrogen cycle
Microbes near plant Microbes near plant roots convert nitrogen from the environment into the forms that plants can use as nutrients in a process called fixation. Fertilizers fixation. Fertilizers deliver nitrogen to plants in a ready‐to‐use form, increasing l t thplant growth.

Manage the nitrogen cycleManage the nitrogen cycle
Excess nitrogen in runoff into the
Mississippi River causes explosive growth of algae in the Gulf of
Mexico. The bacteria that decompose the that decompose the
algae use all the oxygen in the water creating a
"dead zone".S G l SSource: Liam Gumley, Space
