Low Temperature All-metal Stirling Engine Model Toy for Developing Intelligence

EASY OPERATION: Set this engine over a mug of boiling water; wait for 20 seconds; give the flywheels a gently turn; it will be smooth-running quietly and slowly for around 20-30 minutes. Power piston goes with faint sounds when the flywheels is rotating, which even quieter than the tick tock sounds of your clock. This model needs a relatively high operating differential between the two panels (we will explain why in description), so taking BOILING WATER as heat source is a must.
UNIQUE AND GRACEFUL: Twin flywheels are totally symmetrical on both sides of the nicely curved arm and run simultaneously when you give them a gentle turn. Hollow-out parts cut into flower shape beautifies its appearance a lot. 4 aluminum alloy feet & 4 golden fasteners on the top panel truly give this silver engine a more eye-catching appearance. Special anodizing treatment ensures this engine shining for years. It will be a great ornament on your desk.
AN ENGINE WITH FINEST WORKMANSHIP & MATERIAL: Essential parts all made by SUJ2 bearing steel are of precision up to 0.002mm tolerance. Ultra high hardness alloy with high-precision size enables those parts to be wear-resistant and interact with each other smoothly. The bent rod is of high hardness after the heat treatment, strongly stable to keep 2 aluminum alloy flywheels perfectly in the right position. It’s designed to, and we do hope and believe it will, accompany you for years!
WIDE APPLICATIONS: It will be a great conversation starter for everyone around you; a cool desktop piece amazing your friends and colleagues; a great gadget to kill time when boring; a relaxing stress relief physics toy for people in the office; an impressive gift for your families, friends, especially for engineering/physics lovers. It can be used for teaching physics, great to display basic principles of a Stirling engine and to show the art of design.
FANTASTIC GIFT FOR EVERYONE: If you’re always stuck in a choice that prepares a unique gift for someone you love, this shinning engine could be a remarkable one impressing them, gorgeous and funny. Especially for those who owned a Stirling engine before, you should try this one and I guess you will not feel regretful.

 

Working Temperature Differential of this engine is around 40-50°C/72-90°F, much higher compare to our other engines. The main reason is we use a power piston made by bearing steel other than glass! Weight of the power piston is about 26.5g/0.93oz while a glass one is about 6.5g/0.23oz.

To play this engine, simply pour boiling water into your mug, wait for 20 seconds, then give the flywheels a gentle push, it will then rotate by itself for about 20-30 minutes. I don't know what will you do with the engine, for me, every morning when I get to my office, after making sure my boss is not somewhere nearby, I will put mine on mug and watch it rotate for a while.

It is not designed for kids. If you are a starter at Stirling engine I do not suggest this one; if the one you send it as a gift to is not very close to you I do not suggest this one too since it is expensive. In both cases you have wide choices of LTDs in our store. This is an engine that will accompany you or those you love for years. If it is a gift, he/she will think about you every morning:-)

It’s not necessary to lubricate any parts to get it going faster. Finest material with finest workmanship ensure its durability. This is an engine work in good condition for many years without lubrication.

GREAT 80v edger (but Kobalt users beware)
Size: 8" Edger Gen1, Size: 8" Edger Gen1
This Greenworks 80v edger is fantastic. I was surprised at how sturdy and rigid the shaft is - much more so than the very much more expensive Stihl Brushcutter I used for years. I like the adjustability of the blade depth and the power is impressive. You will get more run time with higher amp batteries - I have both 2.0 and 2.5 amp batteries, but if you have multiple batteries and chargers (from acquiring multiple tools) you will never be waiting for a battery to charge. If you have only purchased Greenworks tools, then you are golden. BUT HERE IS THE RUB IF YOU, LIKE ME, THOUGHT THEY WERE STRAIGHT-ACROSS COMPATIBLE WITH THE SAME LINE OF TOOLS THEY MANUFACTURED FOR LOWE'S UNDER THE KOBALT MONIKER AND BLUE COLOR, AS DIFFERENTIATED FROM THEIR STANDARD BRIGHT GREEN. One of the reasons I went ahead and committed to buying the Kobalt line of 80v yard tools was because Greenworks made them and I figured that it would be a long-lasting and stable design platform, being the same 80v system across two different brands. Then Lowe's dropped the 80v line. I was able to get a few more of their tools for great clearance prices and looked forward to switching over to the complete line of Greenworks 80v tools. was very happy to be able to order their edger because it's the exact same power system - just that all of my gear is Kobalt blue. AND HERE IS THE DEAL WITH THAT: They are different. The Kobalt 80v battery will not fit/slide into the Greenworks 80v battery compartment/housing (*as manufactured). - I guess I shouldn't have been surprised - and it could have been Lowe's that required that the stuff made for them specifically would be incompatible. But since it's the same power system, I wondered what the difference was and if I could work-around their obstructionist corporate bs. What I discovered was that the battery compartment on the tools have two long molded channel-guides (male) that match the two long molded (female) channels in the batteries. The vertical placement of the bottom 'rail' in the tool/compartment is positioned in a slightly different spot between the Kobalt and Greenworks 'brands'. But this actually works, because I just used a hand chisel and removed the 'bottom' rail from the Greenworks tool/edger. WA-LA - EUREKA!!! It worked great! It's a great fit, the top rail is more than enough to hold the battery stably in position and the 'lock' mechanism functions perfectly! I am looking forward to buying more tools in the Greenworks 80 volt line without having to replace all of the Kobalt tools I already paid for AND ESPECIALLY the rediculously expensive batteries...

Great product that makes edging very fast
Size: 8" Edger New
Edging was quite a job because I had to do it with a hand tool. I have quite a few Greenwork tools, so I decided to purchase the edger. It works great and I am in general happy with it. The three downsides for me are that tool is quite heavy when it also has the battery in it, that the metal blade decreases in size rapidly because of the friction when edging near concrete, and that the wheel is in such a position that I have to bend substantially while the blade does not edge deep enough so that I have to lean the tool on the metal strip at the bottom of the tool.

Plenty of power. Easy to use.
Size: 8" Edger New
I was amazed at the power of this edger. Due to health issues we couldn’t give our lawn adequate attention. It hadn’t been edged in over a year. This edger cut thru the heavy overgrown grass. Maintaining the edging now is a breeze. It uses the same 80 volt battery as my blower👍. The only negative is there is no edge guide, but once I got used to it, it’s not really needed.
