Solar Car Speed Record Smashed

Posted by timothy on Friday January 21, 2011 @06:13PM from the hats-are-off-to-you dept.

An anonymous reader writes with word from Australia that "There's a new world record for the fastest solar-powered land vehicle: 88 km/h average speed over one kilometre in a lightweight car that uses about the same power as a toaster." As the article goes on to explain, this solar racer, built last year by students from the University of New South Wales, managed to nab that speed record earlier this month on an Australian navy base airstrip.

  88 km/h is very close to 55 MPH
  Toasters use about 1.5 kW which is about 2 horsepower. If one thinks in terms of doing work lifting without other losses, that works out to about 1100 foot-pounds per second.

  I'm gutted about this post for two reasons. Firstly I wanted to make that joke, and secondly I think you might have buggered it up. Kilometers are metric so woudln't they have to use an imperial flux capacitor? Pedantic I know, but that's what I get like when someone beats me to a punchline!

  No, Emitt "Doc" Brown, who invented the thing, did scientific and engineering research in Hill Valley, California over a period of over 100 years (non-consecutive). He would not have used the imperial system of measurement, ever, as California is a US state and would've used US standard units instead.
  US standard is similar to Imperial, but there are subtle differences. For instance, our gallons are a little bit leaner.

  We use metric measurements for stuff like measuring volumes and weights of food items etc, but we stil use miles as our official unit of distance on all road signs, and mph is the major unit on our speedometers. I've never seen any evidence that we have plans to change that, do you have any citations?
  It would be quite a lot of effort and expense to change all our distance and speed limit signs. Not to mention we'd probably have to do it twice - once for dual units, then eventually after a few years switching to km completely, presumably after all new cars have been sold with km/h as the major unit of measurement for a good few years.

  In the Autumn of 1985, at the International Human Powered Speed Championships, a fully-faired Moulton ridden by Jim Glover broke the 200 metres flying start speed record, at 50.21mph (80.79kph). Then on August 29th 1986, at the same event, he broke his own record at a speed of 51.29mph (82.54kph) which still stands today for the conventional riding position. [1].
  It seems that if you design a bike completely around top speed, and if you are a professional-caliber cyclist in excellent competition health, you can beat 88 km/h for brief periods [2]. On the other hand, these are 200 m races lasting under 10 s, so they are a little more sprinty than the 1 km achieved by the car in question.

  Very few humans are capable of generating a kilowatt, and none of the ones that can do it are capable of doing it for 40 seconds (1km / 88km/h). Typically, people consume about 100 watts in food power. Generating ten times that power (mechanically) using just your legs is hard and unsustainable.
  So, you're saying that an engine incapable of generating 1kw can't push the test car as fast as an engine that is capable of generating 1kw at the drive axle (FTFA: 1050w * 0.98). Yes, you are correct.
