Traditional "woolly hat "design

Kids don't have to look different because they are wearing protective headwear.

Engineering features that make SALi based head protection unique

This photograph shows the type of SALi padding used in the prototype hats. The capsules are expanded polystyrene beads in a thick viscous fluid.. The beads can be quite stiff, similar to the foam used in hard shelled helmets, but the fit is far more comfortable, because the pads mould to the shape of the wearers head.
Weight reduction: We can mix the liquid with polymeric microspheres, to reduce the liquid weight.
Cool heads for active sports:  phase change waxes that soften just below body temperature can be used as the matrix fluid. Further softening and eventual melting will occur as the wax absorbs body heat during vigorous activity.

Could Sassy hats offer a comfortable alternative, to conventional, rigid cycling helmets?

The risk of brain damage to cyclists involved in traffic accidents is high. The risk is reduced, but not eliminated by wearing a helmet. Sassy Hats may be superior to conventional hard helmets for some types of accidents, but research must be done, to verify this.

The logjam preventing development:

The Sassy Hats concept is simple, but extensive research into the impact energy absorbing characteristics of different SALi formulations is required before a commercial product is launched. Unfortunately the inventor Bill Courtney is currently unable to win research funding because rogue researchers at Manchester University have published fraudulent research suggesting that SALi is ineffective. This fraud needs to be exposed before the Sassy Hats project can move on.  [See this linked webpage for details.]
