Air pollution from Los Angeles to San Diego has brought clever advice to the city-
If not always practical-
To get rid of the smog.
Such solutions include a huge range of fans.
The other one uses a giant air purifier. Now E.
Stephen Miliaras, an engineer trained at the Massachusetts Institute of Technology, filed a patent for his own idea of spreading smog: a one that will pollute the air directlyMr.
Milaras said he thought when studying the hot air plume that some power plants would release the heat generated in the production of electricity.
In the 1960s s, several studies were conducted on these plume at the request of the power plant in the hope of proving that they did not contribute to the ground
Degree of air pollution
The study found that the plume rose to a height sufficient to penetrate the heat reversal, which gathered smoke in a warm air in cold weather.
At the time of the advertisement, no one thought about using the plume to break the inversion so that the polluted air could escape.
But now, sir.
Milaras has proposed the construction of small gas power plants in smog-plagued cities.
The entire power plant will be housed in a large, 300-500 feet-meter-high double-shaped tower.
In the tower, it is about the third high, and it will be a chimney.
Hot air, as a by-product of power generation, will be forced to rise into the chimney, and the resulting plume will continue to soar for several miles in the atmosphere.
Blinds at the bottom of the tower breathe in more polluted air.
"It's like a chimney in a fireplace . "Miliaras said.
"The warm air inside the chimney weighs less than the cold air outside, and the pressure at the bottom forces the hot air to rise.
"The one sitting on the chimney will be a huge movable nozzle that can be tilted, go through the inverted hole in different positions and break it down.
"You can vent the whole city . "Miliaras said.
An extra benefit, sir.
Milaras said it would be the transfer of ozone from the ground to the stratosphere, a pollutant because at this height, ozone shields the Earth from ultraviolet rays dangerous to the sun, so its depletion has attracted people's attention. Mr.
Milaras said he realized that real estate within the city is a valuable commodity.
So he suggested feather stream-
A chimney is installed in an apartment or office building.
"It will be very quiet," he said . "
"You can eliminate the noise easily. "Mr.
The company of Miriam, headquartered in Energotechnology Corporation, Cambridge, Massachusetts.
, Is looking for financing to test this idea further. Mr.
Miriam was granted patent No. 5,425,413.

Wyner, engineer at Sands Point, Los AngelesI.
He said that his business has been. M.
He said he had come up with a way to prevent potholes. Mr. advertising
Wyner has obtained a patent for a machine that spans the width of the highway lane and has more than a dozen sprayers that use polymer resin under high pressure.
The resin will be applied at such a huge speed, sir.
It will penetrate three to 4 inch of the road, says Wyner.
The resin will then protect the concrete and the steel bars that reinforce the concrete from moisture and contaminants.
"You can extend the road from 30 years to 40 years without the need for repair ,"Wyner said.
He got a patent no. 5,413,808. Squeaky Floors?
Get a 79-year-old GasketCharles Corston who works in the construction industry most of his life.
But it was not until recently that he began to think about how to prevent the floor from creaking.
"It took a friend of mine $4,000 to redo some work," he said . "
Live in Coston, Wash Bellingham.
"People are very angry because there are 13 creaks on the floor.
I think, 'Gosh, they can send people to the moon.
Why can't we stop a scream? ' "So Mr.
Corston invented a way to connect the plastic gasket to the top of the floor beam before laying the plywood bottom layer on the top of the floor beam.
The gasket prevents the floor from rubbing and creaking together with the support beam.
"Usually they just stick the bottom layer to the pallet," said Mr. Corston said.
"But today's Wood is not dry enough. It's green.
When it finally dries, it becomes different, which is why you make a squeak.
"This Sandwell company, based in chagringfalls, Ohio, is producing washers and is planning to start selling nationwide in October. Mr.
Coston obtained the patent No. 5,403,414.
