The Power Problem with Electric Vehicles

EV Power ProblemThese days, it’s all about Going Green. And what could be more green than an electric car?

Zero emissions, baby! Well, sort of…

While the acceleration may be awesome, the range leaves something to be desired. And range is directly related to power – specifically, the available power from a battery pack.

What’s more, the power to charge the battery has to come from somewhere, and that “somewhere” is the electric grid. So what happens if all of a sudden, everyone gets an electric car?

Well, in many places, it wouldn’t be pretty. Some regions would need to DOUBLE their current grid capacity. And all that extra juice has to come from somewhere… and it ain’t coming from solar or wind power!

Why haven’t space suits changed much in 45 years?

Space suitsWhen we watch sci-fi shows, we see these uber-fancy futuristic space suits.

Yet when we look at the actual real space suits in use by astronauts today, we see the same big puffy white suits that look unchanged since the Apollo missions in the late 60’s and early 70’s!

What gives? How come we don’t have fancy space suits yet?

It turns out that there are pretty good reasons. Space suits need to do specific things to protect astronauts…

Is Wi-Fi 6 really that much better?

How good is Wi-Fi 6?There’s a new flavor of Wi-Fi in town: Wi-Fi 6!

In case you’re confused, I’m talking about IEEE 802.11ax, the successor to 802.11ac (which is now called Wi-Fi 5).

Are you confused yet?

While I’m not a terribly big fan of wireless stuff, Wi-Fi 6 does include several improvements that increase capacity and speed for more connected users.

The question is: does Wi-Fi 6 go far enough, or is wired still better?

No more WiFi, Part 2: Home Powerline Networking and MoCA

Powerline Networking and MoCA adapters for home networkingSo you’ve read all the studies about our Wireless Wonderland, and you’d like to go wired.

Or that it’s the first phone (of any kind) that I’ve had in years that actually fits in my pocket?

Deepfakes: Should you be worried?

Oh no, I'm HUGE!Yes, I confess: I was actually the star of the hit 1987 film Predator.

No, not really. But these days, with deepfake software, anyone can make a video or audio clip that shows anyone else doing/saying whatever they want!

There is a lot of angst, anxiety, and worry about deepfakes – but just how dangerous are they?

Obviously, deepfakes have been made for, shall we say, “less than wholesome” purposes such as getting revenge on an ex-lover.

And there certainly is the potential for some chaos.

Can EMF exposure ever be GOOD for you?

Good EMFs?!You all know I’m not a big fan of wireless due to the health risks.

I’ve also said before that resources should be devoted to making these wireless technologies safe – so that we don’t have to just ditch it all!

But then, the question is: Is EMF ever safe?

Better yet, are there examples of EMF / radio frequency energy being used to possibly even HEAL people?

It turns out, there are! And it’s all pretty interesting…
