It’s easy to forget about salt lamps.
The LED lights, designed to improve health by cutting pollution, are still considered a novelty and a luxury item.
But a new study by the Australian Institute of Technology and the Australian Research Council has found the lamps are the most effective and cost-effective way to reduce air pollution.
The study, published in the journal Atmospheric Environment, looked at how salt lamps worked on a local scale and found they reduced the amount of carbon dioxide emitted by burning fuel.
“We found that the salt lamps in the study were the most efficient and cost effective way to improve air quality and reduce emissions from a localised pilot project,” Dr Peter Hausman, the study’s lead author, said.
The researchers said the results could prove useful to the industry, helping reduce fuel consumption and reduce costs.
The lamps can be set up in one of five ways, including the standardised configuration shown above, or with a wider array of colours.
The team also found that, over the three-year study period, salt lamps reduced emissions by 7 per cent compared to the average diesel and petrol fuel used.
Dr Hausmans said the study showed there was a need to test more salt lamp systems to see whether they were more effective.
“There’s so much that can be done with salt lamps that the cost of the systems could be reduced substantially by having more test stations and using more testing equipment,” he said.
“Our results demonstrate the value of salt lamps as a cost-saving measure for cities, and a significant contributor to the reduction in emissions from local power stations.”
Salt lamps are not the only option for reducing CO2 emissions in the US, and there are a number of options that have been proven to reduce emissions.
One of the most popular is to install a gas turbine to run the lamps, which reduce the number of fuel tanks required to keep the gas circulating.
This reduces CO2 in the atmosphere by as much as one-third.
Another option is to use an air capture system that captures CO2 from the air.
This produces less CO2 but reduces emissions.
The cost of air capture systems can range from $US400 to $US2,000 per tank, depending on how efficient they are.
Other types of alternative technologies, such as solar panels, wind turbines and other wind energy technologies, are also gaining traction.
While it is possible to make a salt lamp, it will cost thousands of dollars to make one.
But it is also possible to buy a salt-lamp kit for less than $US5,000.
Dr John Watson, a professor at the Australian National University, said the new research showed there were benefits to salt lamps beyond their ability to reduce carbon dioxide.
“The key thing that is important is that they have a very low cost to manufacture, so that means they are affordable to consumers,” he told the ABC.
“If you’re going to buy one, make sure you do it with the best manufacturer and if it doesn’t work for you, go with another.”
You can have the same kind of problem with a diesel-powered car, and if you have a diesel car you can make a good case for why it’s cheaper to make the petrol-powered one.
“But you need to be aware that a diesel vehicle has to be driven on very clean roads and that there’s a certain amount of CO2 that needs to be emitted to be acceptable.”
It’s not the first time that we’ve seen a product that’s cost-efficient and that can reduce emissions, but I think the challenge now is to make it cost-competitive and have a range of products available.
