He also says that it is very useful for those seeking out the names of companies , <unk> , agencies , and people working on each technology . <unk> identifies one omission : the concern that major investments in clean technology parallel those made during the Internet boom , with the attendant fear that there " may be a bubble burst with clean tech " .
