Lately I’ve been pretty optimistic about self-driving cars…the technology seems to be maturing so quickly, I’ve been expecting them to become commonplace in a matter of years, not decades. A recent photo from Apple has me questioning that – and it’s not a problem unique to Apple, all self-driving automotive technology currently has this limitation.
Take a look at that picture, what do you see? An incredibly complex array of optical-based sensors. Some are lasers, some are cameras. All self-driving cars use something similar, at least based on what’s publicly known right now (GPS is also used, but it just provides approximate location, with no insight into obstacles on the road).
So. Optical sensors. What happens when the lenses get dirty? I used to live in CA so sure, out there they can stay clean for months. Or, as Apple recently announced, the technology can be improved to deal with some raindrops on the lens. But drivers in most of the country have an honest four seasons to deal with, and of course the worst is areas with snow. Not just for the snow that can accumulate on the lenses, but when that snow melts, the dirty airborne mist kicked up by other cars coats your own in a deep layer of muck.
The automotive industry has developed washers for headlights to partially address this problem, but those are imperfect…but maybe good enough for this application? Ideally, I think a true wiper-based solution is needed for each lens.
How will this be solved? I really don’t know…maybe improving the technology used to clean some car headlights. Until then, I do expect self-driving cars to become commonplace, but only in mild-climate urban areas.
Mini is going to be building a limited run of a fan-designed special edition Mini Cooper, an $8900 package price that gives the awesome Tron-themed look shown here. It’s basically a cosmetic package…some LED lights and interior trim options…and unfortunately, doesn’t glow like the real Tron vehicles. But hey, I still want one…
Phinergy has developed a battery that’s, well, a bit difficult to categorize. It’s powered by aluminum and air, but it’s not readily rechargeable. Every 200 miles it needs to be refilled with water, and after 1000 miles, the aluminum plates need to be replaced. So, what’s the point? Well, it has some potential as a range-extender used in conjunction with a conventional rechargeable battery. This Al battery could be a ‘reserve’, or for long road trips, actually replaced enroute (the cost of the raw material being replaced would be ~$50, so it might not cost much to do this). It’s an interesting idea…and ideas like this take creative marketing and some lucky business deals to work out. We’ll see.
