What will those Ivy Leaguers think of next?

One of the world's worst parents works at the nearby law school (and yes I do mean that bellend Amy Chua), but a way better team at Yale University in the US has built the world's first anti-laser — or coherent perfect absorber (CPA). The device, constructed from silicon, absorbs light and dissipates the energy as heat. It's pretty impressive and could make a newer and more environmentally friendly heat source in the near future, but it won't be so good at thwarting laser-based weapons because the energy is dissipated as heat, therefore, use is limited against laser weapons since the heat would damage the target anyway.
