What I had envisioned was a sort of air bag type of protection with an
inflatable suit triggered by some sort of shock sensor. The resulting
inflated "armor" would look something like the "the Michelin Man"

In fact, given the popularity of the auto air bag systems I am amazed
that this over all (would one say all in compassing?) protection
scheme is not required by law in order to protect bicyclists.

You're a bit late to the party with that idea:

There is a real air bag helmet, but at 300 Euros, it's a difficult
sale:

It helps to have a workable product before it can be made mandatory.
Maybe contrive a few statistics which show that we'll all be dead
without an air bag helmet. Of course claiming that what few road
fatalities can be found would not have happened with an air bag
helmet. We're between elections right now, so there should be a
substantial number of unemployed and available political salespeople
to help with the promotion in congress. If it saves but one life.....

Personally, I'm wondering why nobody had contrived a bicycle with and
external frame in the shape of a roll cage. The roll cage frame would
be padded, so no helmet is required. Should it be involved in an
accident, it would simply bounce or roll down the road with the rider
never hitting the pavement. Something like this, but with only one
rider:

With a tiny bit larger hub generator it could have a really impressive

Lights, yes. But I doubt any heating is ever necessary. The bigger
problem seems to be keeping cool. On my normal bike, I always arrived at
work at least a little sweaty, even when the temperature was in the 30s
Fahrenheit.

The AC sounds like a real design challenge, though.

Actually I might be interested in such a helmet. It appears that you don't have to wear anything but a cap while using that thing.

Oh how timely. Yesterday Marilyn Manson proved that guns are
dangerous and that one ought to wear a helmet when around them:

The current belief is that conventional air conditioning takes way too
much power for a human to provide under any circumstance. I think there
might be a way around that but I've not tried it myself.

I don't have one and haven't ever had the opportunity to test-ride
one--but people with velomobiles say that keeping cool isn't a problem
at all, even on very hot days. The interior of a moving velomobile stays
as cool as the surrounding air and most of the perception of heat that
you get is from your head, which sticks up outside the bodywork in the
moving air stream.

Also Velomobiles also aren't normally fully-enclosed, as the humidity
from perspiration and breathing usually fogs up the inside of any
windshield pretty quick. The /racing/ ones are enclosed but they're not
practical for everyday use, for a number of reasons.

Probably, but there are better ways to stay cool:
<https://coolingclothing.shop/collections/evaporative-cooling>
<https://www.thewarmingstore.com/cooling-products.html>
Basically, it's like wearing a swamp cooler. As the water evaporates
from the surface of the vest or hat, the temperature drops. The
material is PVA (poly vinyl acetate) which is quite porous which helps
it retain water for longer periods. You'll find PVA cooling cloths in
the headbands of better bicycle helmets.

One catch is that it works rather badly in high humidity environments,
where the air just can't hold any more water. It's also somewhat of a
problem in very low humidity environments where the water evaporates
so quickly, that you will quickly be too cold.

You can get a similar cooling effect by simply having the bicycle
spray you with a fine mist of water. As the water evaporates, you
become cooler. Water mist spray bottles are available:

I don't know if it is used everywhere but large fans with a "water
spray" system attached so that they blow a sort of fine mist are
commonly used here in outdoor places where people accumulate. Think
"beer garden", and they also make what might be called "room air
conditioners" that are what used to be called "swamp coolers". The
advantage is that a proper air conditioner exhausts about as much heat
as they do cool air and just don't seem to work too well in an
enclosed environment. :-)

Anything is possible. After all we are seeing e-bikes for people that
are too lazy to pedal. Why not a m-bike for those that want to have
air conditioning :-)

We bought one of the pressurized bottle personal misters during one of our trips
to New Mexico. It worked well for my wife, who doesn't tolerate heat well.

It seems noticeably less effective here in humid Ohio. What's the typical
humidity levels where you see the water spray fans used? Maybe I should rig
up something like that for our sunny patio, for next summer.

Ummm,,,,,, in the desert.

The stark reality of evaporative coolers is that they work best in the
very places that typically don't have a lot of water.

~~~~~~~

In places where evaporative coolers work well, some nicer houses even
have them integrated into the central heating/cooling system.
Evaporative coolers also have the side-effect of dumping a lot of
humidity into the air, which, if you have a luxury home with a lot of
fancy woodwork, part of the warranty is that it isn't valid if you don't
take precautions to protect the interior of the home from very-high and
very-low humidity--because the pretty woodwork will all warp and crack.

If retailers don't sell them where you live, then you probably live
where they don't work well.

If you live in a humid environment, all a swamp cooler is going to do is
make mildew grow on everything in the room.

[cycl...@gmail.com]

Actually it's pretty surprising that in the desert the relative humidity often runs to 24% which is humid as hell. Inside your home it's probably around 12%.

[AMuzi]

Yeah, Coolerators are bad enough in Texas but useless in
Wisconsin or (as Frank said) Ohio.

[John B.]

I've seen them used in Thailand and Singapore. Singapore has an
average temperature of 82.5(F), 166 days of rainfall and an average
humidity of 80%. Thailand has an average humidity of 79.9%, average
annual temperature is 89.6(F) and averages 130 days of rain (average
whole country).

Quite a lot of open air type of places have them and my experience was
that it made it feel cooler, but I don't know whether it actually
lowers the temperature appreciable.

The first ones of these I saw was a ring of, maybe, 1/4" tubing
mounted on the face of a 24" fan, similar to
https://www.amazon.com/DecoBREEZE-Outdoor-Misting-Kit-Fans/dp/B002COJB3Y
A piece of 1/4" copper tubing and one could make his own at least well
enough to see whether they were practical.

My wife has a evaporator type of room air con (swamp cooler) and it
blows cool air... or at least it feels cool, even during a downpour.

Re make your own. The first ones I saw were simply a tube ring with
small holes drilled in inner diameter of the tubing aimed straight
across the face of the fan. No nozzles as in the Amazon version.
