Mmmm spicy shrimp

I bought shrimp to make orzo lunches but I forgot mushrooms. I figured I’d get them soon, but I haven’t been to the store - we’re not out of milk, bread, or coffee yet.

So I was looking for lunch and really needing to use the shrimp as they’ve been in the fridge for 5 days now.

So. Heat a sauté pan. Peel the shrimp. Drop butter into hot pan. Melt. Drop shrimp in pan in a single layer. Season with salt & pepper. Cook for 1-2 min. Flip. Drizzle with honey, then sriracha. Sprinkle with fresh cilantro and squeeze a lime out over top. Stir & sauté until desired doneness.

It would’ve been great with noodles or rice but I didn’t want to wait so I just put them on a bed of spinach & “power greens” (bagged mix from grocery store).

Since it was salad like & I love ranch with spicy things, I put dressing on it.

Anyway. If you’re at a loss for a quick shrimp preparation & you like sriracha, you’re welcome.

IBM solar collector magnifies sun by 2,000x (without cooking itself), costs 3x less than similar systems

Cleverly combining solar PV with solar thermal to reach 80% conversion efficiency

Concentrating the sun’s ray onto solar photovoltaic (PV) modules requires walking the fine line between optimizing power output and not literally melting your very expensive super-high-efficiency solar cells. A team led by IBM Research seems to have found a way to push back the line. They have created a High Concentration PhotoVoltaic Thermal (HCPVT) system that is capable of concentrating the power of 2,000 suns onto hundreds of triple junction photovoltaic chips measuring a single square centimeter each (they even claim to be able to keep temperatures safe up to 5,000x). The trick is that each solar PV cell is cooled using technology developed for supercomputers; microchannels inspired by blood vessels but only a few tens of micrometers in width pipe liquid coolant in and extract heat “10 times more effective than with passive air cooling.”

Waste not

The beauty is that this heat is not just thrown away. This system gets useful work out of it. So while the PV modules are 30%+ efficient at converting the sun’s light into electricity, another 50% of the sun’s energy is captured as heat and can then be used to do things like thermal water desalination and adsorption cooling. This means that the system is capable of converting around 80% of the collected solar energy into useable energy (though the electricity is of course more useful than the thermal energy).

A single collector can produce about 25 kilowatts of electricity. Below is a closeup of some PV cells where the light is being concentrated. Notice the piping to bring the liquid coolant.

“The design of the system is elegantly simple,” said Andrea Pedretti , chief technology officer at Airlight Energy. “We replace expensive steel and glass with low cost concrete and simple pressurized metalized foils. The small high-tech components, in particular the microchannel coolers and the molds, can be manufactured in Switzerland with the remaining construction and assembly done in the region of the installation. This leads to a win-win situation where the system is cost competitive and jobs are created in both regions.”

How to Make a Solar Usb Charger from Old garden Lights

With that charger you can charge every device that uses the usb port to charge like : (mp3 player, iphone,psp’s etc.) my solar charger i put some led’s to be able to use it as a torch).

Step 1: What you will neeed

1) two solar panels from garden lights
2) 4AA rechargable baterys
3) 4AA baterry holder
4) one female usb connector
5) a small button
6) a case
7) some wires
8) three 3.6v led’s
9) two 1n5817 blocking diodes
10) one dpdy 6 pin push switch
11) one 150 ohm resistor

Step 2: Taking the solar garden lights apart

Open the solar light and take the solar panel out of the light. there is a small circuit where you can take the two diodes and also some leds battery that come with the light will be about 800mha. we don’d need that low capacity.The capacity that we need from each baterry has to be about 2000mha).

Green Power Smoothie:  


I saw this recipe on a cooking show the other night and I fell in love with it. This smoothie is perfect if you’ve overindulged over the last few days and you’re feeling sluggish and yucky and you need a quick detox. It’s so amazing for your liver, it’s packed with all the essential nutrients that your body is craving during this time, and because its a smoothie, not a juice you’re getting so many benefits out of it, your body will love you for it and you will just feel amazing! 

And of course it’s perfect on a hot day if you need a cool healthy drink to cool you down! 

Ingredients:

2 celery sticks, chopped
 

½ cucumber, chopped
 

1 apple cored and sliced
 

½ tsp fresh ginger, grated
 

Small bunch baby spinach, kale or sprouts 

Put a little filtered water in a blender, then top with the rest of the ingredients. Start the blender slowly then gradually increase the speed until blended.

“Kansas has some of the greatest potential for wind energy in the United States, but the future of wind in Kansas depends upon the continuation of the RPS,” Davis said in an email. “If Kansas were to repeal the RPS, it sends a very strong message to the wind industry that we are not open for business, and you will see people back away from Kansas in a big way.”
