Web pioneer Gross revitalized by green energy

LOS ANGELES (Reuters) - In 1973, when Bill Gross was 15 and cars were lined up at every gas station in Southern California, the aspiring engineer wanted to do something about spiking energy prices.

So he figured out how to build parabolic concentrators and Stirling engines to capture the sun's energy, selling the plans for $4 apiece through ads in "Popular Science" magazine.

Gross, now 49, is again building solar power projects, albeit after a lengthy detour through the early days of the Internet.

His company, Idealab, created a slew of Web businesses in the 1990s, including pay-per-click advertising pioneer GoTo.com and online toy retailer eToys, which he said eventually "outspent its leash."

"Everything we touched was turning to gold for a while, and then the crash came," Gross said in an interview at his headquarters in Pasadena, California. He is not related to the Bill Gross who manages bond fund Pimco.

In its heyday, Idealab was planning an initial public offering, had 5,000 employees and locations in Boston, San Francisco, Pasadena and London. That is down to between 500 and 1,000 employees and one office now.

In that period, he also faced accusations -- since dismissed or settled -- by some of Idealab's shareholders that he used company assets to finance a lavish lifestyle.

Two years ago, Gross was spared financial ruin again when Idealab shareholders agreed to pay off a $50 million (25 million pound) personal loan he owed to a bank.
