Personally, I think that this dryer is a good investment for companies who want to help improve the lives of the homeowners - as they will be able to save money, and be able to get more out of their machine- and help reduce global warming (the dryer uses less energy than previous prototypes).
The idea is good and it is a great start, to have more sustainable ways of using household machines, though, like any other invention there are ways that it can be improved upon. To improve the machine the inventors could have a setting where the owners of the machines could choose the frequency of the wave that will hit the clothing, to blast the water out of the clothes.
