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:

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.

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:

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.

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.


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://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. :-)

Given the light weight of Carbon Fiber it would probably be possible
to build a all enclosing bicycle - I envision a sort of horizontal
rain drop shape that would allow cycling in inclement weather as well
as protecting the rider from accidents.

Those exist. I've known guys who rode them, and we've had posters here
who rode them. See

But I'm forever reading about the joys of winter cycling, the big
fuzzy jackets and the shoe covers, etc.

The AC sounds like a real design challenge, though.

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.

if the patio has unsurfaced concrete or brick watering after noon produces significant local temp reduction

poly 90% cotton 10% or 20 shirts when watered are cold but warmer+ than 100% poly dry .....select for conditions ...next year

weather in Flagstaff is AAA but DOWNWIND
