Phil Weicker and Duncan Forster want to set a speed record. This in itself is a great engineering goal, along the lines of climbing a mountain because the mountain is there. The twist in Phil and Duncan's plan is the transportation mode - they've modified a 1969 Cadillac Deville to be a fully functioning driving hot tub.
The team is running a Kickstarter campaign to raise $10,000 to finance their trip to the Bonneville salt flats for Speed Week 2014 - the campaign ends on July 11th and around half of the goal is still needed. The costs for the vehicle and the watery modifications have already been incurred but towing fees, fuel fees, races fees and safety gear still need to be financed for the race.

Cleverly named the Carpool Deville, the project has received a great deal of press over the last few months but has not yet raised the full Kickstarter campaign amount. The team says that any money raised over the funding request will be donated to the Save the Salt Coalition for future generations to enjoy the racing at Bonneville.
Phil and Duncan say they're doing the project because they can. The Kickstarter page has several questions in the FAQ that ask why the project is happening, and then ask again. The simple fact is that racing is a pure undiluted form of engineering. The project has taken up years of the teams' time and the finished product is spectacular.
Incredible attention to detail has been brought to every component of the mobile tub. A detailed build pictorial is shown on the Kickstarter page. Driving 100 miles per hour in a traveling hot tub is a great goal to have, and Weicker and Forester look like they've done the work to get there.
