There are only a couple of bids available here are the details.
The American Council On Renewable Energy (ACORE), a DC/SF based non-profit sponsors the race, and as part of their sponsorship receives a number of race bids. They then ask for donation in exchange for entries to help offset the cost of the sponsorship.
Normal race bids entries cost $400, if you can get one (there is only a 1/3 chance of getting in after you qualify).
Through ACORE, you can reserve a bid for a $1,000 donation, all of which can be written off (and youre supporting renewable energy!).
