Electric Velomobiles: as fast and comfortable as automobiles, but 80 times more efficient
http://bicycledesign.net/2015/02/a-collection-of-velomobile-links-part-1/ |
Power assisted Velomobiles will become a very
popular for of transportation (when enough people wake up to the facts of
global heating and environmental collapse).
Velomobiles have an efficiency of 40
miles to 85 miles per kilo-watt hour of electricity, depending on the weight,
speed, gears used, and hills you climb. As opposed to 3.7 miles per kWh
for a full sized electric car. How can anyone not afford to own
one of these minimalist vehicles?
Don't be discouraged by the pedaling, you don't
need to pedal at all if you don't want the exercise. But it will give you
better mileage. One man built a Velomobile that is charged by pedaling a
generator rather than the drive wheel.
The
paradox of improved efficiency while it may reduce the environmental
problem wan at the same time lead to greater use of the technology
and eventually result in more consumption and pollution. But if the
size of the vehicle were lowered drastically from what we are used
to, it would take a long time to catch up. That is one reason to keep
the pedals on a vehicle that does not really need them because of the
large amount of power. Think 'two person velomobiles'.

Contrary to popular belief, carbon fiber is not
the strongest material for the body. The only thing that makes it strong at all
is the epoxy. So you could use news paper for the sub-straight. But Kevlar
cloth is the strongest material if stretched tight enough, but probably not the
lightest weight. Some people use wooden door skins molded on the frame.

You can buy a kit to build your own, or you can
get a really nice Velomobile ready made. But you do need to consider the right
power system for these vehicles. Steep hills can destroy an a inadequate drive
system.
If you must use a hub motor, there are some (see
link below) that are much stronger than Crystal Lite, formerly known as the
strongest. While hub motors can produce a longer roving range on flat land,
they have problems with road shock and rain. Some have a disclaimer that their
hub motors can't expect to last more than 7 years. So I would use a 1.6 hp Mars
909 motor and a large rim pulley, just to climb our steep hills with two adults
and/or cargo up to 600lbs total combined weight.
