It's the technology that brought us high-speed wireless and and now, one of Australia's most significant scientific breakthroughs is set to fund future discoveries.

A team of CSIRO researchers has been the toast of the industry after finding the key to fast wireless networks and making $205 million in the process.

The technology has put the CSIRO well in the black for the first time in five years and now the peak science body wants to put back.

It has injected $150 million from the proceeds of its wi-fi technology to the once-defunct science and industry endowment fund, originally established by parliament in 1926.

Work has already begun, with three initial grants having been set up, including $12 million for two wireless research projects and $7.5 million for up to 120 fellowships and scholarships.
