Actor Kelsey Grammer once lost a small fortune after investing in a failed windmill technology project.

The former "Frasier" star reveals his bank balance took a serious hit after he agreed to funnel his hard-earned cash into a new energy plan -- but it didn't work out.

He tells TMZ.com, "It's not really a friendly environment for new technology. It really isn't. You have to have a way in. Big wind is doing okay, but it was a small wind investment, and it cost me a lot of money. ... I'm okay, but I didn't make up for it. It's just one of those things that's just a straight loss."

Grammer refuses to divulge just how much the bad investment cost him, but admits it was at least six-figures.
