Just for a little variety, I thought I'd mention a couple of innovations I came across which caught my eye.
Next month, Aeros will be announcing their intention to build their first Aeroscraft, a new type of hybrid air vehicle capable of hauling large payloads across the sky. Others are working on similar concepts. I think this kind of new heavy transport, with its flexible takeoff and landing capabilities, would be especially useful for infastructure-poor India, and particularly for disaster relief.
Meanwhile, at the smaller end, someone has invented a toothbrush which makes it easier to rinse your mouth, by deflecting the tap stream upwards. I just thought it was a clever modification to a humble common product.
