A new type of solar energy collector concentrates the sun into a beam
that could melt steel. Researchers say the device could revolutionize
global energy production.
The prototype is a 12-foot-wide mirrored dish was made from a
lightweight frame of thin, inexpensive aluminum tubing and strips of
mirror. It concentrates sunlight by a factor of 1,000 to produce steam.
"This is actually the most efficient solar collector in existence," said
Doug Wood, an inventor based in Washington state who patented key parts
of the dish's design — the rights to which he has signed over to a team
of students at MIT.

I don't follow at all what is novel about this. Parabolic mirrors are
old news which is what this simulates.
I'd hardly call the construction revolutionary either.
Nothing to see here, move on. |

Most efficient may simply mean "as efficient as the most efficient designs."
It's marketing-speak. |

If a patent is issued it is issued, that's it.
There are LOTS of cases of non-novel patents being issued -- happens all
the time, big deal.

It is the possible low cost per square foot that might make
a difference, but I doubt it. It would obviously need to be housed
in a glass front enclosure as it obviously would not withstand wind
or hail.
To bad he gave it to a college instead of a private company
eager to invest in real solar production.
Actually, just reading this and thinking about solar has led
me to reconsider the production of hydrogen as a viable method of
storage of energy.

Solar energy collection is a great idea.
However, this guy's "Solar Dish" isn't going to revolutionize squat. |

The examination is for new and novel, plus defining the claims.
How many patents do you have?

Patents are issued on claims.

Possibly not, but if mass production is easy and the price low
enough, that thing could produce about 3 HP, enough to power a house
while the sun shines.
But if architects and builders are not utilizing the most basic
passive solar or ordinary thermal solar in new houses, why would
that concentrating collector make a difference? |

A "patent claim" is supposed to be a precise description of the
physical embodiment of the invention. If you are saying that two
patents could issue for identical chemical formulae, maybe, but there
should/will be a data base to check that.

Sure. But I'm challenging this article's claim that this particular
solar dish is revolutionary. It isn't.
Thanks for the dialog. Have a nice, reflective, day.
it is possibly, in it's light weight, but frankly, that may
be it's weakness.
I have a parabola drafting instrument, and can draw parabolas
within 0.01 percent accuracy, but would I use that to construct a dish
like that?
And I prefer ordinary "float glass" window glass second surface
mirrors for solar energy concentrating reflectors, that is what I have
always used, and will continue to use.
Most journalists today have no idea of how much work was done
in solar energy during the 1970s, and concentrating collectors and
thermal electric have been grossly ignored in favor of the much more
expensive photovoltaics.
Any dish or trough that can smoke wood like that will produce
steam, and steam will produce power, and efficiency is hardly a factor
at all, yet next to nothing has been done in the last 20 years.
A lot of peak power is needed just before noon and late in the
evening, and solar steam plants across the sun belt could help a great deal. |
