Elon Musk says we could make Mars habitable with thermonuclear bomb

On Wednesday night, SpaceX and Tesla founder Elon Musk appeared on The Late Show with Stephen Colbert and announced that the speediest way to terraform Mars and allow humans to live outside of an airlock dome would be to nuke it.
"The fast way is to drop thermonuclear weapons over the poles," Musk told Colbert, prompting the host to call him a super villain. But is the idea that crazy?
The basis of the bomb plot is that the nukes would melt the frozen CO2 on the Red Planet's poles, releasing it as gas into the atmosphere. This would help to thicken up the Red Planet's thin atmosphere, which could be enough to heat the planet and allow water to exist in a liquid form.
Essentially, the bombs would kick-start something similar to the global warming that's happening here on Earth, and hopefully trigger a cascade effect - so the more ice that melts, the more CO2 that's released, which warms the planet and melts more ice, and so on.
However, there are some obvious downsides to this plot. Not least of all the fact that those bombs would also release a whole lot of radiation that may or may not contaminate the Red Planet.
The bigger problem is the fact that they simply wouldn't make that much of a difference, Samantha Masunaga reports for The LA Times.
"It seems possible to make it Earthlike, but there's a lot of barriers to overcome," said Brian Toon from the University of Colorado, Boulder. "Blowing up bombs is not a good one."
Toon also explained that the amount of CO2 already present in Mars's atmosphere is already incredibly high, and while adding to it may make the planet plant-friendly, the atmosphere wouldn't be suitable for animals anyway.
NASA didn't even dignify the suggestion with a proper answer, simply stating: "We are also committed to promoting exploration of the Solar System in a way that protects explored environments as they exist in their natural state."
But in good news, Musk also used the interview to announce that SpaceX would be sending humans into space in the next two or three years, and there's a good change they'll be riding there in this beauty. Let's file that one under transportation goals.

Startup builds AI to automate accounting

Smacc , which uses AI to automate accounting, has secured a 3.5 million Series A round from Cherry Ventures, Rocket Internet, Dieter von Holtzbrinck Ventures, Grazia Equity and business angels. Smacc offers small and medium-sized enterprises a platform to digitize and automate accounting and financial processes. The founding trio Uli Erxleben, Janosch Novak and Stefan Korsch came up with the idea after find accounting to be the most painful part of their own startup. Erxleben managed Rocket Internet’s US ventures in New York and San Francisco, and is also the founder of Berliner Berg , a craft beer startup. Customers submit their receipts to Smacc, which are turned into a machine-readable format, encrypted, then allocated to an account. The platform gradually also self-learns, tracking invoices, sales and costs, as well as their liquidity. The system checks against some 64 data points, verifies the invoice, checking, for example, that the math adds up, and even if the VAT...

AI in Soap Manufacturing Industry

Machine learning (ML) has numerous potential applications in the soap manufacturing industry, contributing to process optimization, quality control, resource management, and more. Here are some examples: 1. Quality Control : ML algorithms can be trained to analyze images of soap bars to detect defects such as cracks, air bubbles, or inconsistent coloring. By automating the inspection process, manufacturers can ensure that only high-quality products reach the market, reducing waste and enhancing customer satisfaction. 2. Predictive Maintenance : ML models can analyze sensor data from manufacturing equipment to predict when maintenance is needed. By detecting potential issues before they cause equipment failure, manufacturers can minimize downtime and reduce repair costs. 3. Supply Chain Optimization : ML algorithms can analyze historical data on raw material prices, demand forecasts, and production schedules to optimize inventory management and procurement decisions. This helps minimize...

Elon Musk to send his Dragon spacecraft on Mars by 2018

SpaceX chief Elon Musk shed light on his new plan to send an unmanned spaceship to Mars as early as 2018, as part of his quest to some day colonize the Red Planet. He appeared to be referring to an upgraded version of the California-based company's Dragon cargo capsule, which is currently used as an unmanned spacecraft to shuttle food and supplies to and from the International Space Station. In a new exclusive this week with The Washington Post, the entrepeneur drew parallels between people crossing the oceans in centuries past to unknown worlds. The months-long journey is sure to be "hard, risky, dangerous, difficult," Musk told the Post, but he was confident people would sign up to go because "just as with the establishment of the English colonies, there are people who love that. They want to be the pioneers." Before that can happen, however, unmanned travel and a supply chain must be developed successfully. "Essentially what we're saying is we...
