Niflheim Media and its subsidiary “WoodHeDid” intends to hand out mesquite wood pieces to the homeless. Urban logging.
The pieces will be cut out but in need of sanding. Sayings can be carved into them by the poor people and sold to tourists and others.

Project STORMFURY was an ambitious experimental program of research on hurricane modification carried out between 1962 and 1983. The proposed modification technique involved artificial stimulation of convection outside the eyewall through seeding with silver iodide. The invigorated convection, it was argued, would compete with the original eyewall, lead to reformation of the eyewall at larger radius, and thus, through partial conservation of angular momentum, produce a decrease in the strongest winds.
Since a hurricane’s destructive potential increases rapidly as its strongest winds become stronger, a reduction as small as 10% would have been worthwhile. Modification was attempted in four hurricanes on eight different days. On four of these days, the winds decreased by between 10 and 30%, The lack of response on the other days was interpreted to be the result of faulty execution of the seeding or of poorly selected subjects.
These promising results came into question in the mid-1980s because observations in unmodified hurricanes indicated:
- That cloud seeding had little prospect of success because hurricanes contained too much natural ice and too little supercooled water.
- That the positive results inferred from the seeding experiments in the 1960s stemmed from inability to discriminate between the expected results of human in

“Lignum vitae” is Latin for “wood of life”
Master clockmaker John Harrison used lignum vitae in the bearings and gears of his pendulum clocks and his first three marine chronometers (all of which were large clocks rather than watches), since the wood is self-lubricating. The use of lignum vitae eliminates the need for horological lubricating oil; 18th-century horological oil would become viscous and reduce the accuracy of a timepiece under unfavourable conditions (including those that prevail at sea).
For the same reason it was widely used in water-lubricated shaft bearings for ships and hydro-electric power plants, and in the stern-tube bearings of ship propellers  until the 1960s saw the introduction of sealed white metal bearings. According to the San Francisco Maritime National Park Association website, the shaft bearings on the WWII submarine USS Pampanito (SS-383) were made of this wood. The aft main shaft strut bearings for USS Nautilus (SSN-571), the world’s first nuclear-powered submarine, were composed of this wood. Also, the bearings in the original 1920s turbines of the Conowingo hydroelectric plant on the lower Susquehanna River were made from lignum vitae. The shaft bearings on the horizontal turbines at the Pointe du Bois generating station in Manitoba are made from lignum vitae. Other hydroelectric plant turbine bearings, many of them still in service, were fabricated with lignum vitae and are too numerous to list here.
The United Railroads of San Francisco (an ancestor of the San Francisco Municipal Railway) began installing lignum vitae insulators to support heavy feeder wires for their trolley system in 1904. The reason for the adoption of lignum vitae was its ability to withstand the high stress at high temperature, a problem posed by heavy cables turning corners heated by high current overloads. Many of these insulators survived the 1906 earthquake and fires, despite temperatures high enough to soften the iron poles and melt the copper cables. Many of these lasted into the 1970s with a small number remaining in service into the first decade of the 2000s (most of these came down when the overhead 600 V DC feeders were replaced with a new system of underground feeders,

Pieces are very seldom seen for sale, as this tree is too small to produce commercially viable lumber. Like the unrelated Desert Ironwood, Black Ironwood is an excellent choice for small turning projects.
Olneya ironwood is very hard and heavy. Its density is greater than water and thus sinks; it does not float downstream in washes, and must be moved by current motion. One popular usage for the wood is for knife handles, since its hardness, grain, and coloring is ideal.
Due to its considerable hardness, processing desert ironwood is difficult. Final treatment of the wood with solutions can also be difficult because of its high density.
Olneya tesota is an indicator species of the Sonoran Desert region. The Sonoran Desert has one other species with the identical north-south, and east-west range. The seasonally migrating lesser long-nosed bat follows the bloom season of various species from south to north and extends into the same regions of the Sonoran Desert as Olneya; (their ranging maps are virtually identical). The bat ranges from southern Baja California del Sur and north into the southwestern United States
It is satisfying to touch Mesquite. I would like to bite it if I was younger…
