The best robot vacuum deals to pick up before Prime Day ends

If you don’t need a robot vacuum that can sweep your baseboards or empty its own bin, theis on sale at Amazon and Walmart for $139.99 ($140 off), which is one of its better prices to date. The entry-level robovac isn’t the smartest option available, but it’s at least aware enough not to bump into walls or tumble over stairs. The 11S Max offers good carpet and hard surface cleaning with relative quietness, too, and its 600ml bin is roomy enough to go through several cleanings before it needs to b

Robinhood is up 160% this year, but several obstacles are ahead

Underwater turbine spinning for 6 years off Scotland's coast is a breakthrough

Submerged in about 40 meters (44 yards) of water off Scotland’s coast, a turbine has been spinning for more than six years to harness the power of ocean tides for electricity — a durability mark that demonstrates the technology’s commercial viability. Keeping a large, or grid-scale, turbine in place in the harsh sea environment that long is a record that helps pave the way for bigger tidal energy farms and makes it far more appealing to investors, according to the trade association Ocean Energy

Judge Finds Tesla Has Failed to Deliver Full Self-Driving, Needs to Issue Refund

After a year of fighting out his case in arbitration, a Tesla owner successfully forced Elon Musk's EV maker to reimburse him the $10,000 he paid for the company's misleadingly-called "Full Self-Driving" driver assistance package, Electrek reports. For over a decade now, Musk has made yearly promises that Teslas will be capable of driving themselves. But the software, even after all these years, still requires users to be able to take over control at any time, making it no more than a middle-o

Robinhood CEO downplays OpenAI concerns on tokenized stock structure

It comes after OpenAI raised concerns about the product, which is designed to give users in the European Union exposure to various U.S. stocks — including private companies, which are less liquid than publicly listed firms. OpenAI last week warned that Robinhood's stock tokens do not represent equity in the company an
