What an awesome heater

My boyfriend is always trying to come up with some invention to make a million dollars.  I can’t tell you how much he has spent over the last couple of years on gadgets, plus how several failed inventions are lying around the house! His latest method for making it to the big time is a portable cooling equipment that you can take camping or the beach or anywhere else. He bought some motors that are battery powered but has had several failed attempts so far. He wants to create something that is lightweight, portable, plus energy efficient, but most of the oness he has come up with are either cumbersome, noisy, or not entirely  effective. I have watched him try then fail several times. I think it is frustrating to him so I wish I knew of a solution. The taxing thing about it is that there are already portable units on the market that he would be competing with as well. I even saw a small counter top one for tiny rooms that was pretty cute. Of course, no portable equipment that is that small will ever cool a large space, but, your immediate area would be comfortable. I guess that my boyfriend has higher aspirations for the portable cooler equipment he wants to design.  He thinks that he can come up with one that can do more that just cool the individual who is sitting near it. I entirely hope that he is successful in his endeavours. If the A/C equipment doesn’t work out right, I am sure that he will come up with another plan.
