According to Technology Review, startup Avanti Metal, using technology developed at MIT, hopes to commercialize a process that drastically reduces the cost of producing titanium, making more of it available for large, lighter-weight airplanes. I know this seems like a non-news issue, but I think it will change a lot of things. Being as strong as steel but only 60% as dense it will now be used in situations where steel was to heavy and other solutions were cost prohibitive. Can you imagine the kind of bridges that could be built using titanium? It's corrosion-resistant and extremely strong. Imagine the Golden Gate Bridge in stainless steel! How about cars? Fuel economy and no rust! I hope Avanti Metal is able to commercialize the process quickly as I want my titanium Delorian! ;)
