Like most Middle Eastern deserts, the Negev is usually associated with sand, rock and the odd camel.
The light is powered by a simple weighted bag, be it sand, rock, or earth, or anything weighing approximately 20 pounds.
The flight bans came amid fears that the ash - a mixture of glass, sand and rock particles - can seriously damage aircraft engines.
According to the company developing the island group - state-owned Nakheel - Palm Jumeirah was built using 100 million cubic metres of sand and rock, and is large enough to be seen from space.

This process of combining of water, cement paste, sand and rock creates an awful lot of CO2 gases - which are linked by some scientists to global warming - about five to 10% of the world's total emissions.
The market cap of Petrobras has shed billions since she took over from what many Petrobras watchers say is nothing more than a policy instrument for Brasilia to funnel money to pet projects, rather than an actual oil company drilling below sand and rock salt in the Atlantic Ocean.
FORBES: Brazil Oil Giant Petrobras Blames Dollar For Collapse
With sections of sand, solid rock and even worn-down bridges that drivers must inspect before crossing, the 200km road takes nearly 24 hours to drive.
Under the process of fracking, oil or gas is extracted from shale rock by pumping a mixture of sand, water and chemicals into the rock at high pressure.
Dredging: excavation, digging, scraping, draglining, suction dredging to emove sand, silt, rock or other underwater sea-bottom material.
As the drill progresses through the rock and sand below the seabed, the pressure of the mud in the drill string must be kept within a limited range.
The company has had to raise capital in order to invest in pulling that oil out of the ground, thousands of feet below the surface of the ocean, and another thousand feet below rock and sand.

Fracking involves drilling horizontally into the rock, forcing sand and water underground to cause tiny fractures that release gas from the shale.
BBC: NI shale gas deposits 'could be worth ?80bn' says report
On reaching the shale, the mixture of water and fracking fluid bursts open the rock and the sand keeps the fractures open, allowing the gas to flow to the surface.
They had been protesting at a site in Hesketh Bank operated by energy firm Cuadrilla which was given a licence in 2008 to extract gas by pumping water, sand and chemicals into shale rock at pressure.

There's no doubt that critics of hydraulic fracturing a practice colloquially known as fracking that involves injecting water, sand and chemicals into underground rock to free vast reserves of gas have some legitimate concerns.
The chemicals facilitate the flow of hydrocarbons, while the sand keeps the pores of the rock open.
Another early beneficiary might be Carbo Ceramics, which sells ceramic pellets the size of grains of sand that are pumped into the rock surrounding the wells to prop open the tiny cracks through which oil and gas flow.
In Tajikistan, on the southern fringes of the ex-Soviet Union, 250 shift-workers are slowly bulldozing a 32-kilometre (20-mile) road from Murgab in the Pamir mountains, eastwards across the rock, salt and sand wilderness of no-man's land, towards China.
And while towns fortify beaches and dunes and put up sea walls, rock barriers or even sand-filled fabric tubes to guard against future storms, state governments are readying hundreds of millions of dollars to buy out homeowners in flood-prone areas who want to leave.
Fracking uses high-pressure mixtures of water, sand or gravel and chemicals to crack rock formations and release oil and natural gas deep underground.
Although barely visible in the air, the ash -- made up of tiny particles of rock, glass, and sand -- poses a serious threat to aircraft, stalling engines and causing electrical failure, experts have said this week.
Tombolo: accretionary deposit of sand or gravel joining a small islet or rock to a larger island or landmass.
The industry has boomed in recent years, thanks to a stunning expansion of drilling in previously untapped areas because of the use of hydraulic fracturing, or fracking, which injects sand, water and chemicals to break apart rock and free the gas inside.
This year he completed what is believed to be the first ever fracture stimulation procedure in Turkey: injecting a mixture of water and sand at high pressure down the wells to break up rock and release gas.
Fracking involves injecting water, sand and some chemicals deep into the earth to crack shale rock, which frees oil and gas.
Composed of sedimentary rock (successive layers of coral, shells, sand, and other materials hardened over time), exploring Coral Castle is like wandering among a man's hopes which have been encrusted with disappointment.
Beachrock: ledges of rock formed within the body of the beach consisting of sand grains cemented by calcium carbonate and formed by chemical processes.
During fracking, large volumes of water, along with sand and hazardous chemicals, are injected into the ground to break rock apart and free the oil and gas.
In the spring, tourists come from all over the world to see the natural wonders: crystalline salt popping out of the ground, sand dunes surrounded by mountains, vibrantly colored, unearthly-looking rock formations and, if there's been enough rain, blooming wildflowers.
Carbo Ceramics is a leader in making what's called ceramic proppant, which is the synthetic material, sand-based often, with chemicals that are injected into the fractured rock to hold open the cavities so the natural gas goes up into the piping that captures it.
