Amazon Alexa

What is Amazon Echo?

The Amazon echo is brand of smart speakers developed by Amazon.

All of the Amazon Echo devices work with a cloud based assistant called Alexa and respond to voice commands.

They can be used to set alarms,play music, and controlling a variety of smart home devices like lights.


How The Amazon Echo Works

The Amazon echo continuously listens for a wake up command which by default is Alexa.

Once it detects this command it sends the audio that follows to the Internet for decoding.

The Alexa personal assistant located in the cloud decodes the audio into text commands.

These text commands are process by a program known as a skill, and Alexa responds accordingly.

Methanol a promising alternative to fossil fuels.  In the area of- Transportation Methanol can be used in road, rail, and marine transportation. It can be more affordable and reliable than electric vehicles (EVs) in some situations, like long-haul transportation.  Methanol engines can be as efficient as diesel engines without the diesel emissions. Energy Methanol can be used in boilers, process heating modules, tractors, and commercial vehicles.  Cooking Methanol can be used as a cooking fuel in stoves and canisters that don't require pipes or regulators.    Benefits Environmental impact Methanol can reduce nitrogen oxide emissions by up to 80% and carbon dioxide emissions by up to 95% compared to fossil fuels.  Accidental spills not harmful for environment as methonol is biodegradable,  ' Production Methanol can be produced from a variety of sources,  agricultural products,  municipal waste,  wood, and biomass.  from chemical recyc...
