There are a host of technologies in development or embodied in products and systems which claim to be clean or at least cleaner. How do you judge between them? What is just greenwash and which are the genuine gems? There are many issues to consider, of which the foundational one is the underlying science and engineering.
CleanTechNet is a growing database of clean and cleaner technologies assessed on their scientific and engineering merits by engineers.
With this focus the database is an excellent tool for more closely understanding which technologies are the best for meeting our need to be compatible with our environment.
The database entries are specific products and systems rather than generic technology classes. They are at all stages of development, from R&D to commercially available.
Each entry has a rating from A++ downwards, enabling users to rank selected entries and to identify best in class.
Entries also highlight complementary clean and cleaner technologies, which could be combined to provide enhanced value.
CleanTechNet has been developed in spare time and there are many ways it can be developed if it starts to develop an income stream and involve more people of the same mind and specific expertise.
