I'm taking an engineering course in thermodynamics, so I find this post quite interesting. (final's on Friday, ugh, hehe) 70% efficiency is
freaking amazing. Most of the stuff I've studied is usually in the 30-something percentage efficiency range. Strangely, my textbook does not
mention Brighton cycles (I thought it might be a phonetic misspelling of Brayton) but
I did a google search and Brighton cycles apparently exist, but I could only find a single relevant link, and it was to an academic paper whose text I
could not read without a subscription.
I am skeptical about the 70% number, though. The ideas of heat recuperation and isothermal compression mentioned in the article are already used, and
are quite old. Unless the 'isothermal compression technology' the article refers to is something new and revolutionary, I don't see how they can
reach that kind of performance. "GVE Inc claims the JVT is 58 percent to 70" but I find even 58% hard to believe. If they've got some new really
good insulators, maybe they could reach 58.
If this engine does work as claimed, it could potentially revolutionize the industry, especially if, as Sigma hopes, they can get these into cars.
I'll be very interested to see where this thing goes in the future.
