The company JustWinglt is currently experimenting with new materials for their new line of luxury jets. Conventional panels were constructed using 7075-T6 Aluminum alloy with each panel weighing 500 kg. JustWinglt has decided to use a 60 v/v % boron reinforced Al-Li alloy composite to make the panels instead. Calculate the potential savings from the reduced weight assuming each kg saved reduces fuel consumption by 2000L per year. Cost of fuel is $10/L.
