New mobile "High quality" airconditioning that you can take with you everywhere.

This company is advertising on Youtube (in Belgium). They tried to reïnvent the weel but failed to do so.

They claim that the aircon that consumes only 7.5-12.5W can compete with "real" airconditioning installations with an in- and outdoor unit. Do you smell bullshit too?

Just an evaporative cooler. They were sold everywhere in last summer. Obviously they are not nearly as effective as a real AC and increase humidity which is something you don't really want when it's hot (unless you live in a very dry climate zone). Besides, with humidity increasing, this approach also becomes less and less effective.

One of the NASCAR racers built a rig to keep him cool in the race car.  It was a picnic cooler full of ice and a small pump.  He put some kind of tubed panel, likely from some medical device up his back under the nomex jacket.  I don't know if this got banned, or now everybody uses them.  Such a rig would be trivial to build.
