Sean McCarthy: It varies from configuration to configuration. I think the largest efficiency that we would have physically measured would be about 485%. These numbers can be misleading. For example we might be getting 485% per joule, which means were getting 4.85 J out, but there could be a configuration that’s could be delivering 130% efficiency yet delivering 10 joules. So, the technology itself is pretty well researched in terms of punch line efficiency it’s 485%, but that wouldn’t be the optimum output of the system. Obviously we’re more focused on direct power output of a device than the punchline numbers. 485 to 1 is 4.85, but we could easily say, 10 to 12 joules off of a system is going to have a lower punch line efficiency. And power output is obviously the key factor, energy output is obviously the key factor.
