It costs money to keep it operated. I'm surprised they've lasted this long with practically no products to sell. It costs a lot of money just to keep an office.They supposedly have millions of dollars, but are hidden away and not showing off their technology. The test track rarely operates and there are serious doubts as to whether or not the trains can hit advertised speeds given its short length.
They are smart to keep their money hidden. A company that small with practically no product to sell would exhaust those millions very quickly, if it weren't locked away somewhere.
