Hey great post..I think this is the must read article for those who are really worried about their energy expenses thanks for sharing these great ideas as I also believe that future lies in these renewable sources of energy.

If you're going to have an article about a product with an embedded link it would be nice if that product was on the website.

I could not locate the solar experiment kit anywhere on the company website.

Interesting spotlight on developments in battlefield robotics and thinking behind the MAARS device.

It may be able to be timed to let one set of con rods work at the point of ignition with more leverage than normal? as in the Scuderi S/C engine

Dear Sirs: the sintering machine via laser, is SO COOL! I know Jay Leno (Entertainer, car builder/collector/restorer) uses some similar type of machine to build "un-obtainable" replacements to keep his almost 200 different cars running/maintained. Could parts as strong as forgings be made(--as in one-off small sets of rods used for race/other hi-performance IC-engines)? Why is there a limitation of only 10" or so in height? There might be applications where one wanted to do an engine-block that would have a height of way more than 10", yet would need a "one-off technology (--as in a marine diesil powering a cruise ship/oil tanker/military aircraft-carrier/cruiser/other?

the lower the work load on the engine the less fuel it needs so less carbon production thus this would reduce maintainance DON'T LET THE OIL COMPANIES FOOL YOU THEY WANT AUTOS TO BURN AS MUCH FUEL AS POSSIBLE

This is identical, I believe, to what "Inphase Technology" does with their microinverter. A friend has 24 panels on his roof; at times, clouds/trees/etc. will shade a panel or two and the whole string is degraded in performance. By selectively cutting out non-producing panels, the string's output is not effected. Remember, when one panel is dark, it begins to act like a resistor, causing a significant problem for the inverter. Also, a smaller inverter can be used since tolerances are easier to maintain, lowering the total cost for the system. These small "microinverters" usually cost about $100 - $200 dollars and are guaranteed for 10-15 years. I personally have not included solar panels in my "efficient" home as of yet because of the difficulty in panel placement and the extensive design choices that have to be made when calculating the panel size. One major point I see to these small units is this: a single panel can be added at a time, instead of requiring strings of 8-12 units or more. This alone is an attraction for most people. You simply add panels as money becomes available.

I believe these units are the single biggest advance to come along in solar electric design in a very long time and will greatly influence how quickly panels become commonplace on roofs across the country!

But what is the efficiency loss. Like she said, you don't get something for nothing. Power loss from 100%?

Brilliant technology! While we all recognize the need to blow up the bad guys, I am also thinking the "ghostswimmer" could also be used to monitor undersea turbines as part of the overall alternative energy initiative.

Thanks for an outstanding report. I am a professor who welcomes this opportunity to inspire students. Cool!

This engine is alot different, it solves alot of problems of normal 2 strokes. First of all your tubo is going to be more efficent , exhaust port open and charge air ports closed. Next, you can pressurise the cyclinder with the intake charge. And most important, Low amount of ring drag. To get the same amount of power with a 4 stroke, the amount of dead piston movement would be measure in feet..Detroit diesel stated that on their engine that just .5 inches longer stroke would kill efficiency.
