Electric Velomobiles: Urban Transportation For the Future, Available Now 201
An anonymous reader writes with this excerpt from Low-Tech Magazine: "Both the velomobile and the electric bicycle increase the limited range of the cyclist — the former optimises aerodynamics and ergonomics, while the latter assists muscle power with an electric motor fuelled by a battery. The electric velomobile combines both approaches, and so maximises the range of the cyclist — so much so that it is able to replace most, if not all, automobile trips. A quarter of the existent wind turbines in the U.S. would suffice to power as many electric velomobiles as there are Americans." One thing I wish was included in the article — worth reading for the photos alone! — is a chart with prices and worldwide availability for more of the vehicles mentioned. They do mention, though, that the eWAW ("the Ferrari of the velomobiles") costs 7790 Euro.

You can fix the tire problem by running hybrids, like armadillos. You can fix the suspension problem by buying a shock with a stop that can be fixed. Then the only problem is the extra ten pounds of bike you're lugging around that could have been a street bike. Thing is, IMO street biking is solely for people who don't care if they die excessively sooner than necessary. And an enclosure that isn't a crash cell only makes the experience more dangerous by severely limiting your mobility. In the worst case I can fling myself off of my bicycle, possibly off of an embankment, to avoid a car, if one should try to run me down on one of the fire roads I occasionally have to use between trails. If I were sitting down in a plastic cocoon all I could do would be to pedal hard, steer for the embankment, and hope that I slide into a tree soon rather than down the hill forever.

The thing about a bicycle is that I am more at the mercy of others because they are moving so fast I cannot possibly get out of their way if they screw up badly enough.

It's not a panacea, amongst other reasons due to some of the issues raised in the article, but all too many people seem to think it is impossible to ride a bike to and from work on a daily basis (I'm not saying you're one of them).
This is in stark contrast with what you see in large European cities like Copenhagen, where 35% of all workers and students [www.kk.dk] use a bicycle for their commute. That's a city where the municipality alone has half a million people, and what most people would consider the urban area has another 700,000 inhabitants.
Is it a panacea? No. But I wouldn't mind seeing what'd happen in Copenhagen, if the eWAW and similar bicycles were legal to use and affordable in Denmark. I'm pretty sure we would see a lot more bike riders.
It obviously won't replace everything - goods still need to be transported, not everyone wants to ride a bike (even if they don't have to provide any power themselves) etc.
It's a relatively small area, and since the eWAW seems to be capable of about 60 km unassisted at 30 km/h with a small battery (I'm guessing 500 Wh), this would rival make a lot of car commutes once you take rush hour into consideration, and with commutes about 30 km or less, we're not looking at close to two million inhabitants.
With a 500 Wh battery, you'd need 1,000 MWh to charge the batteries needed for two million bikes. Let's call it 1200 MWh by including some inefficiencies in transmission and charging. And let's assume that on average they need to be charged in 4 hours.
That requires 300 MW in production capacity, or to put it into perspective, roughly the same energy as put out by 8,000 cars using 50 HP. 300 MW is less than 8% of the wind power capacity in Denmark as of 2011 [windpower.org]. And as someone pointed out, charging a 500 Wh battery can be done with a relatively small solar panel. And while it'd obviously increase the weight and cost, I wouldn't be surprised, if you could get most of the 250 W, that the motor peaks at, from panels installed on the bike itself.
Incidentally the cost of charging a 350 Wh battery is less than one Euro (DKK 4.22/kWh or roughly 57 cent/kWh [dongenergy.dk]) at the most expensive prices I can find. It's pretty difficult to find a cheaper way to travel 60 km.
Sadly these bikes aren't cheap. Not even close to cheap. They seem to cost in the neighbourhood of 5,000 to 10,000 Euros, which puts them fairly close to the cost of a small car, and thus makes them much less viable as a replacement for the car for commuting.
It's a shame, because it'd make for a serious decrease in local air and noise pollution.

However, I think the big problem for these is safety, particularly if you must share the road with cars, trucks and busses.

Combine that with the extremely low profile... let's just say that the odds of getting caught dead in one of these seem a little high for my comfort.
Now, in cities with excellent bike networks, that wouldn't be such an issue - IF the vehicle actually meets the legal requirements for use on bike paths.

It remains to be seen if electric assist has any effect in this thing. TFA says that two vehicles were tested, one with electric motor and another without, and they were performing identically.
Think about it this way also. TFA provides calculations of the efficiency of the vehicle. 100W from the driver + 250W from the motor seem to be a great idea. But it all depends on the weight of the electric powertrain. A skinny rider on an unpowered bike will be far faster than the same skinny rider who carries the fiberglass shell, the battery and the motor in addition to the bike's parts. If the rider's weight is 300 lbs then perhaps the battery's weight is not that critical; but riders with those characteristics prefer Harleys :-)
Finally, TFA clearly spells it out: "The electric motor is intended to be used for acceleration only (and for climbing hills)." This is counter to the theory that a casual rider can use the motor instead of pedaling. The battery (288Wh) would be good for more than 2 hours, isn't it so? But for some reason this is not the mode that they tested. Perhaps this vehicle lacks the transmission (electric or mechanical) that would be required to handle the full range of torque? But whenever you are NOT using the electric assist you are hauling all that extra weight for naught. That would be a big loss in overall efficiency. Prius, for example, is using battery power whenever it is not charging the battery; Toyota's designers understood well that you must use the battery, otherwise you'd be better off losing it.

I guess you've never seen a car hauler with a winch. You can use rolling jacks to slide the car into the street, then winch it into the car hauler, and drive away with no one the wiser. Or on a hill, you can park a flatbed downhill from the vehicle, and winch it that way.

Diesels generally require less service, though they do often have higher parts costs. These days though gasoline engines are going to direct-injection, so they have both a high-pressure fuel injection system and a spark system. Subaru in particular has a lightweight diesel engine because they are using opposed pistons, which would be an ideal genset motor if produced in a two-cylinder configuration. It would sound ghastly but there wouldn't be any pulsation feel from it if it were only running a generator.

Only suited, it seems to me, for use in large numbers if you've got more land to waste than you know what to do with (which is the case in some parts of the world but not others).
In constrained city streets there is neither the road space nor the parking space for vehicles like this. OK so it might be a modest improvement if motorists started using them, but it would be a pretty catastrophic backwards step if existing cyclists started using them in any numbers.

without mentioning it, the author of the article assumes that you will completely drain the battery on every commute, for both the velomobile, and the electric car. With that completely rediculous assumption, he comes to the figure of 25% of the windturbines.

I have a velomobile. I ride between 6 and 10 thousand miles a year - which is actually pretty easy, given that the velomobile is fast and protects you from the weather so you ride year round without any trouble.
With the gasoline I save, the depreciation of the car I don't use when I ride the velo, parking tickets I don't have to pay... the velo paid for itself in 3 years. After that it's all free miles.

This would only be close to true if you limit your car usage to match what you use the "velomobile" (whatever that is) for.
I have an two-seat enclosed recumbent bicycle, which ought to be pretty close to a "velomobile". The bike is a good replacement for a short leisure trip, but not for much else. Shopping, especially weekly shopping, longer trips, trips with more than one person and a half, trips in bad weather, etc. are all much easier and much more pleasant in the car.
So, forgive me, but I feel you're stretching it quite a bit.

I will hypothesize that the poster originally wrote "I have an enclosed..." and then edited it to add "two-seat" but failed to adjust the article.
By the way, the conjunction "and" does not ever, in English, substitute for the article "a". Don't you mean "Does no one know how to use a and an anymore?"

No, we do. Incorrect grammar has a tendency to spread; people use it because they've read it elsewhere so often that it pops to mind when they're writing text themselves. I even find that I'm beginning to think "it's" for the possessive form of "it", because that error is so damn pervasive.
Many people, when called on bad grammar, will use the defence that "nobody cares so I'm just going to continue being wrong". If the GP wants to go around correcting them of that notion, then I will support him in that.

Some languages have prescriptive grammars: you do it this way because that's the rule. Latin and ancient greek are that way, mostly because they are dead languages that can no longer change.
English has a descriptive grammar: you do it this way because that's the way it is done. That is one of the reasons it has emerged as the global language of the Internet, and one of the very few languages that sees more use among non-native speakers than among those who were raised with it.

No insurance, no Shaken, no gas bills? A battery small enough that you can drag it back to your apartment to charge it?
Kei cars, insurance and gas costs, at a conservative 5000 miles per year, will still run you like $1500 per year average. That pays for the velomobile in about 7 years.

Yeah. Many people have different transportation needs in Japan. I live in a compact city where my farthest commute is 7KM each way. So for me, a road bike works perfectly. Paid about 5 man for it, and I can make the commute out there in about 25 minutes. This works for me because i've essentially (with repairs) paid a little over 3 man a year i've had it, over 3 years. So it's been a good investment versus getting a kei car (20 man), driving school (no license, so 30 man), 3 years of insurance (30 man), shaken (10 man), and gas (my odo says i've gone 4k on my bike, so let's just say that would be probably about 6 man) . So i've saved about 10 grand.
But if I lived in a town where my farthest commute was more like 40km, cycling would be impractical. So i'd have to go that route. Plenty of people live in the burbs and commute in, for them a kei car is economical. That's their living situation.
However, where the Velo really comes in handy is when you're commute is like 20km, because a Velo can easily maintain 50kph with a fit cyclist, doesn't mind rain, and etc. If you're commuting 40km round trip, your kei would be eating 3/4 of gas a day. 5 days a week 45 weeks a year that's 8 man a year just for gas. You tack on supplemental insurance (10 man a year) and you're shaken (10 man every 2 years, so let's just say 5 man). So you're looking at a yearly running cost of of 23 man. At those prices, that 8000 euro velo will pay for itself in 4 years. And if you're spending say, half an hour in the gym per day to stay fit, you can shift that half an hour in the gym to your hour of cycling. Considering that, the times would equalize.
So there are many different angles you can work on this. Some people might pick the Velo. I know I would, for fitness. The same reason why I haven't bought a car, only having a bicycle forces me to cycle everywhere and has helped me loose 50 pounds.

Unlike a bicycle, you'll need a parking spot for this in Japan. Also, I am not quite sure what kind of treatment you will get in terms of license requirements from the government. I'm afraid this thing will be treated more like a scooter than like a bicycle on the account of speed and size. As for "doesn't mind rain", well, my tricycle disagrees, it does mind rain a bit. You can't get in and out the same way you do form a car.
So, yeah, for a niche market it probably makes sense, but for most people that need transportation and not a toy it doesn't look like a good choice.
But maybe we'll see some interesting development as the genre matures.

Another problem, no matter how many Americans drive their Velomobile, there will still be exactly as many Freight Trucks on the road who already have trouble seeing small cars and motorcycles.

Shouldn't 200 watts be plenty? IIRC, a human being can only put out 100 watts average and less than 300 watts peak - so 200 extra watts roughly triples the average output of a human-powered bicycle and significantly boosts the peak output.
