Mining Weekly reports that the price
of tantalum oxide will go up as the market experiences a supply squeeze.
While researchers already knew the potential value
of tantalum oxide for memories, such arrays have been limited to about a kilobyte because denser memories suffer from crosstalk that allows bits to be misread.
White remains cautious, though, and would like to see more work looking at whether some of those 10 watts might be coming from the piezoelectric properties
of the tantalum oxide, rather than from its interaction with the droplets.Ten watts would be enough to power a mobile phone, a military radio, a GPS device, even a small laptop, Krupenkin says.
