Concentrating light onto PV cells has been done before. The main problem is that the PV cells get too hot and degenerate quickly. Bulky panels using mirrors or lenses can be solved using flat fresnel fenses.
Now the question remains, how to cool these things. It dawned to me that the panel created so far is in fact very similar to the solar water heaters. Why not combine the two?
A fresnel lens concentrates the light onto a PV panel that is protected against heat by water flowing up between two layers of glass (Hot water rises) circulating as it does in traditional solar hot water systems.
The water takes out the heat producing IR radiation leaving all the good electricity generation radiation for the PV panel.
This way you can put up one panel producing both hot water and electricity.
Just torn open the packaging from the CD/DVD. The sticker say's this software can not be returned to the retailer after opening the package. During install I am presented with an EULA and I do not agree with it.
Now what! say goodby to my $100 and toss out the software? because I can not return it. So I agree. All EULA's are agreed to under pressure because you have no other option since software returns are almost never possible.
In my opinion all software should be returnable to the retailer provided the CD packaging has been unopened. Packaging should contain a EULA in a printed form so it can be read wintout opening the CD/DVD packaging.
And all this still doesn't warrant the stupid content of these EULA's. I never ever read a EULA and treat a software product purchased in a store just like anything else I buy it a store.
Automatic parking? That only works at night time here. Before 5 AM and after 10 PM. Why? At any other time there are no free car parks! Whooooaaaaa ha ha ha ha. Parking. Yeah sure (And I drove around the block again hoping in vain to use my $700 parking feature)
Indeed GPS is a far simpler way to reference speed information for a road.
New Zealand roads have some pretty challenging layouts and not all dangerous bends have speed signs.
An onboard database can contain far more detail about the speed curve recommended for a certain bend.
Rather than distracting audible or visible signals I propose a force feedback on the accelerator pedal. Mind you this is NOT cruise control but an accelerator pedal that nudges you foot back up until you have decelerated to the database recommended speed.
Tried a computer model based on this where a forcefeedback joystick acts like the accelerator pedal and it works!
My dear friend, Lord of the Rings crew, did not pack up and leave. Contrary to popular believe, the Lord of the Rings Crew are mostly New Zealanders that are still here working on the next block buster.
YES! Finally some sense. So many times have I walked past the Lego shelves frustrated that there is nothing fun on there. Soon there will be (I hope)
anyway, what I want to say is that I am glad that Lego discontinues the themed stuff. Back to basics great. Have designers design great looking designs using standard bits and box them, as long as the bits can be used for something else.
This also applies to specialised parts. Pneumatics, motors, CPU's and so on. They are all parts that can be used to build the most amazing things.
Therefore. Yes to back to basics but No to dumbing down. Lego is interseting for kids up to 99 years old.
