Hello,
I work for a company that is developing a new type of portable heater using
system of permanent rare earth magnets and spinning disks that runs off of a
PTO and produces large quantities of dry heat very efficiently. We are
looking for suggestions as to suitable features and functions as well as
data on the types of areas heated on a farm. Anyone interested in commenting
on the below questions or making any other suggestions would be greatly
appreciated.
What do you consider the most common applications for a portable heat source
around the farm?
What would be the typical size of an area you would need to temporarily
heat?
What would you say are the most important attributes of a portable heating
system?
(cost, reliability, output?)
What are the most successful attributes of your current method of portable
heating?
What are the least successful attributes of your current method of portable
heating
Are there areas associated with farming/agriculture that currently are not,
but would benefit from being heated? Why are they not heated?
Can you think of any benefits that having a PTO based heater may bring?
Can you think of any drawbacks that having a PTO based heater may bring?
What size of tractor would you run a device like this from?
Thanks for your input,
Rob

Why not just use a friction brake?

This post is worth absolutely nothing and is probably fallacious.

There are portable heaters already available that probably are a lot
more efficient than anything relying on a tractor PTO. What advantage is
there to what you want to do compared to portable kerosene heaters?
One type of portable heater was nothing but a steel tub with a lid on it.
There was a flue at the center of the lid maybe 5 feet high. One poured
diesel fuel into the tub and lit it. Heat output was regulated be opening
and closing a vent on the lid.
Some grain drying systems need heat. Those are typically fueled with
natural gas or propane. These are usually drying bins or things like batch
dryers. Hog farrowing operations probably need some heat when the pigs are
young.
You're asking a farmer to use an expensive piece of equipment to produce
heat. There would have to be some big advantage to your system to justify
that. Tractors aren't cheap nor are repairs.
These are a couple examples of your competition:

The price is under $500 U.S.
Good luck,
Dean
