World Solar Challenge Set To Begin 78
"My Alma Mater's
team (which took second in the
American Solar Challenge...go UMR!) is looking to take sweet
revenge on the evil (*g*) that is the U-Michigan Solar
Car team (which won
ASC.) Some other North American heavyweights will be
Queen's University

are often

Re:No Survivors (Score:3, Informative)
Actually, they're safer than that..
Usually the battery packs are kept compartmentalised from the rest of the shell so that they can't spill onto the driver. There is also usually at least two driver's egresses built into each car (even if that egress means kicking out the bottom of the car).
The crashes that do happen are usually brought under control very quickly. The brakes on these things are usually quite good, and the cars are usually able to be salvaged (and of course the drivers are generally safe).
As long as the team is aware and treats their drivers nicely (there are some horror stories about, for example, seatbelts being tied to the chassis of the vehicle bit a couple of bits of wire), then the cars are actually quite safe.

There are competitions involving fuel cells, including Future Truck [futureenergies.com] and karting [futureenergies.com]. Fuel Cells take a lot of R&D but when their price begins to decline we will see a lot of independant parties begin to become creative with what can be done... then we will see an increase in the number of races.

The big oil interests certainly have an interest in green energy... if it will make them money. Look at BP buying up all the small solar companies and cornering the market in solar cells.

Fuel cell technology is certainly not being ignored, it has massive momentum behind it. Most of this is from the car companies, who don't really care what goes into the engine (oil, hydrogen, etc) as long as people buy their cars. If fuel cell technology fails to take off it will be because of public apathy in supporting it, prefering to pay slightly less for old established petrol based polluting machines instead of the new and inevitably to begin with more expensive green option.

NO: Solar cars today are an experiment in engineering, not a solution to your everyday commuting needs. We can get relatively high speeds and drive all day, but the cars are very wide and long, flat, only hold one medium-to-small person (barely) and are limited by the environment.
YES: Any electric car could easily be supplemented by the addition of a high efficiency array. It wouldn't provide enough power to drive the car all day like we do with the current crop of cars, but since most people only drive their cars about 2-4 hours a day it could help a lot, and could be a real lifesaver if you ran out of power. OTOH, even a well designed commuter car is going to be much heavier than our solar cars and have much less array area. What would make the most sense is for all carports to have arrays on top that could store and transfer energy to the cars parked under them.
MAYBE: I don't know that electrical cars or fuel cells are the (near) future. Chemically propelled cars can potentially be much simpler and more efficient, since they aren't losing power through the extra electrical storage/transformation. And you can make fuel using solar power (you already were with the fuel cells). And until efficiency actually matters and the big-ass SUVs get off the road, it just won't be safe for extra-lightweight cars.
BTW, the plane thing has already been done with the Helios project. And you're right, it has a lot of potential.

Chemically propelled cars can potentially be much simpler and more efficient, since they aren't losing power through the extra electrical storage/transformation
I do a lot of solar projects (mostly on a miniature scale, won a few small solar competitions, etc), and sometimes keep an eye on some commerical electric car developements, and my understanding is that the opposite is true - anything with a combustion engine suffers from hundreds of moving, wearing parts, relies on kludgey, expensive additional systems (clutch, etc), dumps all it's energy every time you hit the brakes - then wastes fuel getting back up to speed again. (Which in a city commute might mean you're spending ten times the energy actually needed. Hence hybrids getting up to four times the mileage).
Electric engines are cheaper to make, last longer, more reliable, often involve no moving parts bar the shaft itself, gruntier even when running on significantly less energy, etc etc.
But until an electricity storage system gets to the point where it hold even a signficant fraction of the energy that petrol does, you're right.
BTW - I'd be interested to know how many orders of magnitude less energy these solar cars run on compared to a combustion car - can you give us an idea of what a typical solar-racer solar panel output is?
Re:No, yes, and maybe (Score:2)
When I talk about chemical engines, I'm talking mostly about potential efficiency. There are some pretty amazing engine designs out there - there was a recent article about a rotary engine that only had one moving part besides the shaft and valves and required no lubrication.
Most teams use the same type of engine, which is built into one of the wheels. It's a lot louder than you would expect (makes this wierd popping noise) but gets better than 90% efficiency. OTOH the power range it can provide is limited.
I'm not sure about orders of magnitude, but I can tell you our car runs on about as much power as a hairdryer.

Most of the "power" for the solar cars actually comes from the batteries.. Queen's University's car, for example, in the '99 WSC could run at 70kph on the array alone, but at 120kph with the battery power as well.
So, yeah, they practically are a secondary form of power, but still.. The technology used there, goes on to more practical applications.

They rebuilt their car 17 days before the ASC because it was destroyed during testing. They have a GaAs solar array, Lithium Ion or Lithium Polymer batteries, a very sleek design, and 4-wheel steering. Apparently when they redid the 4-wheel steering, they replaced the mechanical linkage with an electronic control. It's the most advanced solar car I've ever seen.

A lot of fundamental research was done on improving the efficiency of electric motors, their drive electronics and simulations as to the most efficient way to drive these vehicals. Hell, even the telemetry to the support vehical was something pretty new for the time!
There ought to be many more of these sort of worldwide research challenges. Especially in areas that really will become important soon such as fuel cells as others have pointed out.
